#49 – Analog Devices, Design Spark - Unusual Usenet Usurpation

Dave Jones: Welcome to the Amp Hour. I'm Dave Jones from the EEV blog.

Chris Gammell: And I'm Chris Gammell from Chris Gammell's Analog Life.

Dave Jones: Hey Chris, what's happening there in Cleveland, Ohio?

Chris Gammell: Not much. I finally got a new chair for my workbench that I built oh so many moons ago. Excellent. Is it on wheels or is it a... It's on wheels. I got the little... It's a drafting chair. I had this realization. I was looking for tall chairs and all these different search terms online and everything else. That's the search word you have to look for is drafting chair.

Dave Jones: Oh, okay. Draft and chair, right. Yeah. Okay, mine's just like a cocktail. Mine's just like a bar chair. Like, you know, one of those... Oh, like a stool? Yeah, a stool. Yeah, a bar stool kind of thing.

Chris Gammell: Yeah. There's a whole range of them and it's got like a little footrest and it's actually padded. So I can sit here for more than an hour without having to get up and do a little dance.

Dave Jones: Nice. Yeah.

Chris Gammell: So...

Dave Jones: How many hours do you actually spend at the bench?

Chris Gammell: Well, when I'm doing like work or, you know, consulting or anything like that, then it can get, you know, up into the many hours. Yep. You know, like on a show night, like when we record, you know, I'm sitting here for the hour and a half that we usually talk and then another two hours.

Dave Jones: Yeah, because that's right, because you're actually in your lab, aren't you? Not... Which is different to me. I'm not in... My recording studio isn't the lab, it's my study. It's my recording studio. So I spend most of the day in here because it's where the computer is and it's where the internet is and... Yep. And that is the bringer of knowledge. That's right. Yeah.

Chris Gammell: Or the biggest time waster ever invented, whichever way you want to look at it. Yeah, that's... Yeah, it's been... It gets tough sometimes. I mean, how have you been handling that? You've been able to...

Dave Jones: Working from home, yeah, it's a time sink, you know, because I've got to have the internet open in front of me because I'm researching stuff. So I've got to have, you know, 20 different tabs open with all the data sheets and whatnot there. And it's like, oh, I'll just go check forum for five minutes and I'll just go check this or I'll just search for this or, you know. And, yeah, an hour later, you've just pissed away because, oh, well, you just get carried away.

Chris Gammell: Yeah, you know, my fiance sent me this article about how the internet, like, messes with your brain or something like that. Oh, it's called... Right. There's an article, yeah, it says, does online life give you popcorn brain? I didn't...

Dave Jones: Oh, okay, as in jumping from one thing to the other. Yeah, that makes sense.

Chris Gammell: I mean, basically the idea is the internet gives you all this instant gratification. Like, you know, we talk about Twitter, right? So I say something like, oh, I need help finding, you know, a new CAD package. And within maybe 20 minutes, I'll have 10 people saying, oh, I'd try this, try that. Yeah, try that. Or I did that with, like, revision control. I asked about that last week. You know, what people's...

Dave Jones: So you've got to go check out each one, right?

Chris Gammell: Right, exactly. But it's like this instant response and your brain just goes crazy. It's just so much dopamine. Like, yeah, get another hit, get another hit, post something else, another hit, you know? It's like, that's... I mean, it makes sense from, like, a biological perspective. Like, it's addictive, right? So there... And there's an actual... Absolutely. ...internet addiction. But at the same time...

Dave Jones: Oh, yeah, yeah, it's real, you know?

Chris Gammell: When she said this to me in a very accusatory manner, I said, what am I supposed to do? That's where they keep all the data sheets. That's where, you know, I communicate with people about...

Dave Jones: I know, that's the problem.

Chris Gammell: Yeah.

Dave Jones: You have to be in there to do your work. And yet, that's the... That's the thing that sucks all your time. Like... Yeah. Well, it's... I don't know. You've got to be... I try to be, you know? I try not to go search wiki or something like that. Oh, well, no. Even if you are researching something and you end up in wiki, all those seductive hyperlinks, you know? Oh, yeah.

Chris Gammell: Where you just go, like, link after link after link.

Dave Jones: Yep.

Chris Gammell: Yeah, that's the worst.

Dave Jones: That's the thing that made the internet, isn't it? Hyperlinks was the... Yeah. You know, was the big thing. Well, that actually... The web. That actually made the web. It made it so easy to jump from one thing to the other. And that's its downfall, too. Yep. When it's sucking your life away. Yeah.

Chris Gammell: So, I mean, I always wonder about that, too. Because, you know, you read these studies about, like, oh, well... At least with, like, double E's, right? So, all the old double E's aren't online at all. It's like, okay, I get that. But, like, they're not online in the same capacity that other people are. But I guarantee they're on there getting data sheets.

Dave Jones: Oh, of course.

Chris Gammell: You know, checking e-times or EDN or anything like that. You know, that's just how people commute. That's how they get information these days. It's kind of hard to avoid unless you're still getting data books, which I don't think a lot of people are.

Dave Jones: Oh, no. No. But, yeah, we're more of the social nerd, aren't we? Because we participate in forums and whatnot. I mean, I've been on forums since, you know, 12, 13, 14 years or something. I don't know. Yeah. Like BB forums, everything. Yeah, I've been on them for a long time. Oh, that's right. You were telling me about... I just like the social aspect.

Chris Gammell: You told me about the Usenet groups. You were... Because when... That's right. ...Piece died, you said, oh, I'll post this to Usenet.

Dave Jones: Yeah. And there's a lot of old timers still on Usenet.

Chris Gammell: So... What was the actual board it was that you...

Dave Jones: Psy Electronics Design News Group. Okay. So, Psy.electronics.design.

Chris Gammell: So... Yeah. And there's a whole bunch of them. I really... I mean, I've never... I mean, Google Groups, you can do with that kind of thing. I've never really done that before.

Dave Jones: You can do it using Google Groups, but if you use Google Groups, most of the old timers will just block anyone from Google Groups. So, they won't even see your messages. Which is weird. Because that's where all the spam comes from. Oh, oh. Because they do the right scripts. If you're a Google Grouper, you get no respect whatsoever. So... Yeah. And I switched over to using Google Groups. But if you've been on there a long time, they will put you on their whitelist so that they can read your messages because you're well-respected and, you know, you're not just a dumb Google Grouper.

Chris Gammell: Yeah. You know, so... Yeah. Many of them. Right. Is it like because people come in and just ask, like, these new questions?

Dave Jones: Yeah, these idiots. They don't understand what actual Usenet is. So, you get all these young, snot-nosed idiots coming on thinking that, oh, it's Google Groups. And, oh, you know, and it really riles up all the old timers. It's not Google Groups. It's Usenet. You know? They get angry and they say, piss off. Yeah, exactly. I've been on here for 20 years. Yeah. Piss off. You know, it's Google Groups. And, oh, yeah, that changed the entire Google Groups, changed the landscape of Usenet. So... That's interesting.

Chris Gammell: Oh, you know, that's how you said you've talked to Wyn Hill before, right?

Dave Jones: Yes. Yes, I've talked to him via... I think you were mentioning that two episodes ago. Yeah, yeah. Wyn Hill's a regular on the side. That's cool. I mean, it's kind of like the back-end channel of the EU world. Yeah, yes, it is. It's kind of like a back-end channel.

Chris Gammell: That's cool. I like it. And, of course, now we're going to have, you know, all the Amp Hour people go through there, hopefully. For sure. There will be the Google Groupers that get... Right, the Google Groupers. ...opticized, and then the Amp Hour listeners that all come in at once.

Speaker ?: Right.

Chris Gammell: Guys, trickle in. You know, we'll start giving out numbers.

Speaker ?: Right.

Dave Jones: But most of the people left on there are just all the old-timers, you know? Yeah. So, there's very few new people coming through to... And actually stay around on those sort of groups. It's pretty much just the old-timers, really.

Chris Gammell: You know, I used that when I was at one of my former co-ops. I was doing FPGA work, and I was... I had the same kind of interaction with, like, you know, more experienced engineers. Yeah. But the thing I don't like about all those, like, username boards and everything, it seemed like any time I search for my email address on Google, that's always the thing that comes up. You know, that's always the thing that's, like, causing spam for me. So, I don't know. I just thought I'd put that in there.

Dave Jones: But the ironic part of it is, is that if you use Google Groups, you don't get any of that spam. It's brilliant. Oh. So, yeah. Google Groups is actually a great way to use Usenet, except nobody listens to you because you're blocked. But, no, apart from that, it's actually a nice interface. That's why I started to use it before all the spam started, before the spammers discovered that you can spam Usenet via Google Groups. And, yeah, then it just went downhill.

Chris Gammell: Yeah.

Dave Jones: Ah, well. Yeah. Speaking of, yeah, pissing away time, we've just pissed away 10 minutes on something that wasn't even on the list, as we tend to do each week. That's okay. That's a given every week, isn't it? That's organic, man. When you start out the show, it's organic, right, is the wank word. Right.

Chris Gammell: It's organic, man. Yeah.

Dave Jones: We don't just jump into the list, do we? Well, what's on the list?

Chris Gammell: And sometimes, you know, we have guests call in unexpectedly, and we just got to talk to them for a while.

Dave Jones: That just came out of nowhere.

Chris Gammell: That guy was crazy. Literally, he's freaky. Hope he doesn't call back.

Dave Jones: I hope he doesn't call back. I think he's had his five minutes of fame.

Chris Gammell: Okay. That's good.

Dave Jones: All right. All right.

Chris Gammell: What have we got? We got any shout-outs? We had one shout-out, maybe two. I want to give a shout-out personally. So, I wrote over the weekend, you know, about Bob P. Stine. Obviously, we talked about that last week. And, you know, I really hadn't thought about it until I was writing about it, but I kind of lost, like, two writers, two, like, electrical engineer writer heroes of mine. You know, Jim and Bob both were writers and engineers. And so, kind of, like, looking at the ones that kind of brought up the third spot was actually Junko Yoshida from E! Times. She's actually the editor-in-chief. I don't know. But I just wanted to give a shout-out to her because she wrote this piece about Japan. She went to visit her mom over in Japan. And this thing read, like, a New York Times article. It was just, like, brilliantly written and, like, really touching and kind of creepy, even, just because of how she wrote it. So, I'll link it in there. But, I mean, she's basically my number one must-read column these days. I don't know if you have anyone like that other than reading my stuff.

Dave Jones: Yeah, probably not really because I'm not into writing and that sort of stuff. I suck at it. You know, I've written a bunch of articles over the years, but I think I suck at it. My English skills are absolutely terrible. My wordsmith skill. I don't know. What's the word? You know, wordsmith? Literary? Literary skills. Literary skills, yes. Yeah. Thank you. See, I even suck at that, even knowing the term. So, that's how bad I am. So, yeah, I don't... I'm always jealous of people who can write really well like that. Write eloquently and, yeah. Are you talking about me? Are you talking about me now? No, I'm afraid not. No, I know. I don't read your column. Sorry. No, it's all right, buddy. It's all right. No, you write pretty well. So, that's good. It's a very good skill to have. I found, though, it's a skill that doesn't help in your report writing or something like that. Not at all. It's a different, you know, engineering reports. If anything, it makes you ramble.

Chris Gammell: It makes you... Yeah.

Dave Jones: Yeah, I'm actually quite good at doing reports and stuff like that. But, yeah, when I have to write one of those really wordy, feely, you know, New York Times style articles, yeah, I just wouldn't be able to do it.

Chris Gammell: So, pretty envious, as usual. Junko writes a lot of good stuff, too. Her article caught my eye today because she was writing about Freescale. And, you know, they just had this forum, the Freescale Tech Forum, where they always have, like, this monster... It's kind of like the Renesas one you went to. Real similar. You know, like, very specific to the vendor. Right. Okay. They'll bring in third-party vendors, but they're really just there supporting the main vendor. And, uh... I don't know. I mean, she always just writes great stuff about that one, so I like that one, too, because she, uh... Reading about Freescale is its own thing, because Freescale is kind of like watching a plane crash. Oh, right.

Dave Jones: Because they're a massive company, Freescale. Are they still number one? Well, no. No, no. They're number two in microcontrollers, Freescale. So they are still massive, right?

Chris Gammell: They are huge. They're huge. But, uh... Yeah, I mean, they've just been... They're a sink and ship, basically. I mean... Right. Okay. Anyway.

Dave Jones: In terms of losing money, I don't know. I haven't followed it for quite a long time. Well, we talked about that on here. Are they just losing the shit? They're just bleeding cash, are they?

Chris Gammell: Well, they... Yeah, I mean, they're a monster fab. They have their own fabs. They're hemorrhaging cash, you know? Hemorrhaging cash. There you go. Yeah. You know, they're a monster company, but they just have... Because they got bought out and now they went public again. We talked about that a couple weeks ago.

Chris Gammell: They went public even though... And they lost all this money. They got bought for $17 billion and now they just went public for a billion. So it's like, hey, where'd that $16 billion go? Oops. So it's all... You know, they're just a... They're a train wreck. I've used three different, you know, analogies of transportation crashing, but they are... Yeah, they're a mess. So anyways, that's what caught my eye. And that's what... That's why I was talking about Junko, so...

Dave Jones: Sweet.

Chris Gammell: Yeah. All right. The other quick shout-out was for Amazon. If people don't know... I don't know if you knew about this, Dave. Amazon? But if you're a student... Why are we shouting out to Amazon? It's not really a shout-out so much as like a life hack. I found out about this and I used it to get this chair I'm on. So if you're a student or if you just have a student email address, as I might possibly have... Right. They give you Amazon Prime for a year, so I got like $4 shipping. It was awesome. So if people don't know about that, I thought that was sweet.

Dave Jones: Amazon Prime. What's that? I've never heard of it. No.

Chris Gammell: You get like free two-day shipping on everything and you get like $4 one-day shipping from Amazon. Oh, right.

Dave Jones: Okay. Right. See, that means nothing to us because Amazon won't ship shit here. They'll only ship books and CDs. That's it. Oh, that sucks. You know, they won't actually ship products here. So it's... Yeah, it's... Oh, that sucks. Yeah. I know. It's stupid.

Chris Gammell: Well, never mind then. I guess shout-out withdrawn. Right. Not that it was one of the first ones.

Dave Jones: Because it's not Australian compatible. It's not world... Right. I don't know if it's just... I think it's other countries. I'm sure it's other countries as well. Yeah. They won't ship any electronic items at all. You know, you can't go and buy a camera or something like that from Amazon or a multimeter or something. Really? Yeah. Can't do it. They will not ship.

Chris Gammell: So when you put those links on your site, you put those links, that's just for people in the US that can buy electronic stuff? Yeah.

Dave Jones: That's pretty much it. And other countries who they will. Well, it also depends on the third party. If it's... I think if it goes through a third party, they might be able to sometimes ship to other countries. But yeah, definitely anything by Amazon themselves, they won't ship overseas.

Chris Gammell: That's weird.

Dave Jones: Except for niche stuff like the Amazon Kindle, which has a market here and stuff like that.

Chris Gammell: Right, right, right.

Dave Jones: But yeah, I don't know. It's annoying.

Chris Gammell: Yeah, that is annoying.

Dave Jones: Anyway, I haven't tried for a long time. But maybe they do now. I don't know. Anyway, I think they send some items, but not others. It's just crazy. Hate it. Yeah. Thumbs down to Amazon.

Chris Gammell: Oh. Sorry. Shout out with drawn. Excellent. Yes. So what else we got here?

Dave Jones: I don't know. We're not very coordinated today, are we?

Chris Gammell: No. Not really.

Dave Jones: Yeah. I don't know. We just sort of cobbled this together at the last second.

Chris Gammell: Don't you mean we've been preparing for weeks? Of course.

Dave Jones: Yep. Well, I've been researching components again. Yeah. And I searched for a low-power ADC, low-power 16-bit ADC.

Chris Gammell: So this is for your secret consulting gig that no one knows about?

Dave Jones: No comment. Okay. And there are – here's a stat of the week. There are approximately – I'm not going to claim this figure is actually totally accurate, but there are 2,000.

Chris Gammell: I guess this is a DigiKey figure right here.

Dave Jones: No, no. This isn't – no. No, this is where DigiKey is useless. You've got to go direct to the manufacturer's website. Oh, okay. Yeah, they just don't have the right parametric search you need. So, oh, yeah. No, you can't. You just use DigiKey and cheat here. Yeah. There's 2,412 ADC devices on the market from 24 different manufacturers. There you go.

Chris Gammell: Wow. So roughly 100 ADCs average per manufacturer.

Dave Jones: Yeah, roughly. Some have 500 plus ADCs. Right, yeah.

Chris Gammell: I'm sure the big ones.

Dave Jones: Yeah, the big TIs and those sort of ones. Analog and everybody else. Maximum. Yeah, analog. And, yes. And that brings us to chip of the week.

Chris Gammell: Ooh, doing it early this week, huh?

Dave Jones: Doing it early. Who cares if we put it at the end? Does it matter? Or do you want to leave it until the end? No, it doesn't matter to me.

Chris Gammell: That's perfect to talk about.

Dave Jones: Right. Well, and it came down to there really is not much. Well, there's a few. No, there's a few. There's like half a dozen choices in the ultra-low-power 16-bit analog-to-digital converter. And by ultra-low-power, I'm talking 100 microwatts, right?

Chris Gammell: Okay, 100 microwatts at a certain sample rate?

Dave Jones: At 8 kilohertz sample rate. Okay. So, yeah. Which is reasonably quick for a 16-bit converter. You can get lots of low-power 16-bit converters, but they all run at like 300 samples per second maximum or something like that. Yeah, yeah. To get a faster one than that is, you know, is not easy. It comes down to, yeah, there's maybe, you know, eight or ten different devices on the market out of those 2,412. And the chip of the week is, ta-da, the analog devices AD7691 because I found that to be the best 16-bit low-power ADC on the market. And it just so happens to be not 16 bits. It's 18 bits. So you get an extra two bits for free. Woo! Great. And, yeah, and it takes 108 microwatts at 8 kilohertz sample rate, which is bleeding-edge stuff. It really is. I mean, you know. As somebody on Twitter, I think, pointed out, it's like 0.1 picajoules per sample or something. Yeah, I was just going to look at that. They converted it to energy per sample.

Chris Gammell: So that's about, so at a 2.5-volt rail at 100 microwatts, that's what, like 40 microamps? Does that sound about right?

Dave Jones: Calculator time?

Chris Gammell: Yeah. Okay, so 40 microamps. So on a AA battery, what would that be? Or two AA's, rather. So 40, because I'm on Wolfram Alpha. I think we did this before where if you type it in there, actually.

Dave Jones: Using calculators on air is, like, pretty much a big fail.

Chris Gammell: Oh, I thought they put this in here. So sometimes they do that, but oh well. What is the current of a AA battery, or the amp hour rating of a AA battery? It's like 2,500.

Dave Jones: A AA battery is 2,800 milliamp hour.

Chris Gammell: Hmm, 2,800 milliamp hour.

Dave Jones: We're talking 40-odd microamps, because it's 108 microwatts divided by 2.5. Right.

Chris Gammell: So 2,800 divided by 0.04.

Dave Jones: So what's 108 divided by 2.5? That's 40-odd microamps or something.

Chris Gammell: Yeah. That's 70,000 hours on two AA's.

Dave Jones: 70,000 hours?

Chris Gammell: 70,000 hours, if that's right. So 40 microamps. How many days does that convert to? Divided by... This makes for good radio. I know, right?

Dave Jones: Nerds on radio. Nerds on radio.

Chris Gammell: That's 29... It would have been easier if Wolfram Alpha would have just told me. That's supposed to just tell me the answer. That's 2,900 days or 365 equals eight years.

Dave Jones: Eight years is basically the shelf life of the battery.

Chris Gammell: Yeah. So that sounds about right. Yeah. Not bad. All right. Way to go, analog devices. That's pretty cool. And so...

Dave Jones: Except, of course, sorry, this is a nerd electronics radio show. You can't, unless you had a DC to DC converter in there to keep a constant voltage, you wouldn't use up all the usable capacity in the battery because its lowest voltage is 2.5 volts. So, yeah, you'd probably only get like three months or something out of it before the battery voltage dropped to a level where the chip couldn't operate or operate within spec.

Chris Gammell: Three months out of eight years? Really?

Dave Jones: Oh, I don't know. Probably. It's going to be small because, you know, the terminal voltage, right, of that battery is three volts. It only... Chip only works down to 2.5. It's not much margin there. Oh, okay. Maybe you might get a year or six months or something out of it. But, yeah. I don't know. With switchers.

Chris Gammell: Switchers aren't bad. I mean, they're getting switches up to, what, 95% now? I mean, like...

Dave Jones: Oh, yeah, but then they have extra quiescent current and stuff like that. Eh, I don't know.

Chris Gammell: Yeah. I'm sure... Well, and also, this wouldn't be the only thing in the system either. You're not just going to pump a signal directly into A to D. I mean, is there like a front end on this thing or what is it? No, no. It's just a differential input.

Dave Jones: Okay. Yeah. Standard differential input, zero to two and a half volts. It doesn't... Ah, that's the catch too. It doesn't have an internal reference. So, you've got to piss away some more current with your external reference.

Chris Gammell: Huh. Yeah. Bugger. And so, the app note on this thing, or the diagram, they show the single-ended differential op amp. And I've seen this circuit before. And why have I seen this circuit before, Dave?

Dave Jones: Because you're apparently an analog guy.

Chris Gammell: Ah, no. No, or did you claim... How much specific to this situation?

Dave Jones: You claim that you found this chip for me.

Chris Gammell: I suggested you look at the Pulsar family. Yeah, I did.

Dave Jones: Oh, unbelievable. I did a systematic search of 24 manufacturers. Thank you very much. That's right.

Chris Gammell: And Chris picked this one out of a lot. Yep.

Dave Jones: Well, you only picked the family.

Chris Gammell: There you go. Yeah.

Dave Jones: And it's by sheer luck that it happens to be... Well, I don't know. Yeah. The LT ones get very close in terms of power consumption. In fact, I think technically one of the LT parts might be slightly lower consumption. But, yeah, there's...

Chris Gammell: I mean, yeah, they're both scraping the bottom of the barrel in terms of how much they're actually using. So, and I mean...

Dave Jones: Oh, yeah, it's insanely low.

Chris Gammell: It's crazy. Yeah. It's... I mean, the interesting thing about that is like, I can't tell you the number of times where it's with all this... Excuse me. With all this choice, I mean, that's almost the best way to do it, you know, where you at least have a starting point, you know, like, or at least a reference point. Hey, I've used blank chip before. Why don't you check around that and say, oh, no, that's not going to work for me. Then you can just throw out an entire... Like, if you had looked at that family I suggested, and then you said, no, I can't use this. This is too much, you know, too much quiescent current or too much, you know, uses too much current or it doesn't go... You can't scale back the sample rate or something like that, you know? Yep. If that was the case, then you could just throw out that whole family right away. Oh, of course. Yeah. Creating some monster spreadsheet, like I'm sure you probably had to do anyways, but...

Dave Jones: Well, no, I created a smallish spreadsheet. Oh, okay. Two of them that, you know, had parts of interest. Yeah, I could just rule out manufacturers, you know, of those 24 manufacturers, they might have had... Well, some of them only had one device, you know? It wasn't that hard to look through. So, you know, yeah, but you can sort of rule out entire families and stuff like that. Well, tell me about that.

Chris Gammell: It's not as hard. What are some of the smaller ones? Because, I mean, I know the big ones like Analog, LT, TI, they all make really great analog digital converters. All those guys do, right? What are some of the ones that maybe only make one that I might not have heard of before?

Dave Jones: Okay, I've got a list here. I have a list. Here we go. One's that... Well, there's advanced linear devices. They make six ADCs, but you want one that makes one. Okay, let me look down. Oh, no, there's one that makes two. Okay. Oh, InterSyl. You remember InterSyl? Yeah. Yep, they still make ADCs. That's crazy. And they make two of them. Freescale have one ADC. There you go. We talked about Freescale. They've got one audio codec, you know. Go figure. What have we got? NGR has got three. Silicon Labs have one ADC. Okay. Yep. Two ADCs from ST Micro. Wavefront is another manufacturer, which have one ADC.

Chris Gammell: Yeah.

Dave Jones: I bet you've never heard of Wavefront.

Chris Gammell: No.

Dave Jones: Yeah. They make professional audio ADC convertors. So, they're like real niche companies. Really niche companies. Niche.

Chris Gammell: Yeah. Niche.

Dave Jones: Niche. I love it how you say niche. Yeah, there you go. And some of those only make one ADC or two or three.

Chris Gammell: Right. And so, some of them might even be like the, what did we talk about last week? We talked about that with the Android chip. The fabulous semiconductor companies. The ones that are just guys sitting in an office block where they're doing simulations.

Dave Jones: They do a cuticle and they simulate and they, yeah. Hand it over to a fab. Send it to a fab and that's it. Bingo. You're now a chip company.

Chris Gammell: Yeah. Which is cool. I mean, if you've got the money, you need money. You need a lot of money, right? Oh, yeah.

Dave Jones: Yeah. You need money to do it. But, hey. You can. You can be one guy in a garage, rich, but you can still form your own semiconductor company.

Chris Gammell: Yeah.

Dave Jones: It's great.

Chris Gammell: Speaking of, Touchstone. Those guys. How many times have we mentioned Touchstone? I know, but now they're like official. That's the thing. So, we've talked about it. We talked about it at the beginning before. I don't know. I don't know how we, I think we found out about them on Twitter. I don't know.

Dave Jones: You dug them up from somewhere, I think. Yeah.

Chris Gammell: Well, I found them on Twitter the first time. So, and then they just had some announcement in E-Times. They had all this press release stuff. And, yeah. So, they're like one of those fabulous companies. Same thing. And so, now they're second sourcing. I don't know.

Dave Jones: They're second sourcing Maxim parts. It's not that exciting news. I'm sorry. It's, you know.

Chris Gammell: It's not exciting. It's, it's interesting though. Oh, yeah. Because all their people came from Maxim. So, I would just think this is a lawsuit waiting to happen. You know. Okay. I talked to one of their guys there and, you know. Really nice guy. He told me all about like what they're doing and stuff. And, you know. They're obviously targeting their, their very, their very targeted market or whatever. But, yeah. If you're coming from Maxim, you'd think you'd, you'd shoot for someone else's knees.

Speaker ?: You know. Right.

Chris Gammell: Maybe they've got a grudge. I don't know. So, that's.

Dave Jones: No, I can certainly understand that. If you come from a company and you didn't think that they did it right in some way. Yeah. Yeah. I could, you know. Your goal would be to take them on. Yeah.

Chris Gammell: Yeah. That's interesting. And, I mean. And, I'm not saying this is the way it is. But, you know, we've talked about on here before. You know, Maxim parts have been historically hard to get. Maybe not anymore. I'm not speaking about that.

Dave Jones: No, because they changed their slogan and everything's fixed now. Right.

Chris Gammell: Yeah. Innovation delivered. Right. But, if that is the case. And, if that's the. Those are the knees you're shooting for. Maybe they are shooting for the right knees. But, I don't know. First time I read that.

Dave Jones: It would be ironic if you can't buy the Touchstone semi parts. Please tell me you can actually buy the Touchstone semi parts. Right.

Chris Gammell: They're just like these poison parts.

Speaker ?: Right.

Chris Gammell: Yeah.

Dave Jones: Oh, that would be hilarious. Anyway, I won't say you can't get Touchstone parts. I'm sure you can.

Chris Gammell: Yeah. So, they're grown up. And, they. I mean, they got funding too. That's another thing they wrote about when there was a big press release. They got Series A funding. Whatever the hell that means. Out the Silicon Valley. Sure, it's important. Yep. Sounds serious. Money. Money rocks. So. Right. Yeah. I don't know. It's cool. But, I don't.

Dave Jones: Yeah. It's a tough gig though. It's a tough gig trying to start up a semi. Any sort of semiconductor manufacturer.

Chris Gammell: I can't imagine starting a company like that. You know, I can't imagine starting a company in the first place. So, starting a chip company is.

Dave Jones: Yeah, I know. It's just.

Chris Gammell: A whole other game.

Dave Jones: You know, because it's so important when you work in the industry to pick established parts from a big brain. A big name manufacturer. Yeah. You know, like you'll get almost, you know, almost fired if you buy some little one hung low brand. You know. Right. So, if you actually spec in a one hung low brand part. Right. Into your design. It's just. So. Right. Exactly. Yeah.

Chris Gammell: If you went and designed this, whatever this thing you're working on. Right. So, if you went and went with one of those manufacturers that. Say you picked the freescale part. You said freescale is making an A to D, right? One. Yeah. Yeah, they make one A to D. If they turn around tomorrow because they're doing all these internal changes and they say, oh, we're not making that anymore. Yeah. You're up a creek without a paddle, right? Exactly. I mean, like you're screwed. So, yeah. It's the same. That's the same risk that any new company takes, right? It's like, well. Yeah. That's right. We can deliver. Okay. Have you always done that?

Dave Jones: Well, this is what we talked about. When we first talked about Touchstone, we said that they have to differentiate themselves by having a part that absolutely is so unique nobody else has that you've got no choice but to design that part in. Yeah. And then it's fine. You know, if you come down, well, your specs to get your product to the market need this chip. There's no other chip on the market that does it. Well, fine. Yeah. Spec it in. Yeah. But, yeah. I don't know. But just doing second source Maxim parts, well, that can't hurt. Yeah. Especially when Maxim probably still don't deliver their innovation. I don't know. I'm not going to claim that.

Chris Gammell: Yeah. I mean, to be honest, I haven't bought Maxim parts in a while, so.

Dave Jones: Yeah. Same here. Or if I have, they've just been in prototype quantities and, you know, I haven't cared about it. Because you could always get prototype. That was the thing with Maxim. They would do the best prototype service in the industry. You could always get their parts. Yep. But then when you tried to buy, you know, 100,000 of them, you're screwed.

Chris Gammell: Anyway. We'll have to try and talk to a Maxim person sometime to let them settle the score. We could duke it out on the air or something.

Dave Jones: Oh, but then we'd end up with just all the spin that they'd tell you. Oh, and I'd be throwing up on air and it wouldn't be pretty. Sorry, people, if you're eating.

Chris Gammell: Yeah. Oh, well. Oh, well.

Dave Jones: Let's get on to CAD, shall we? Yeah.

Chris Gammell: Yeah, definitely. So there's a new announcement from DesignSpark, who we've mentioned on here before. And I think it's kind of cool, actually. Yeah.

Dave Jones: I haven't tried it yet, but I think it's a good idea.

Chris Gammell: Yeah. They just released a new converter tool. And I don't think it's built in. Right.

Dave Jones: No, a separate tool. Right. Yeah.

Chris Gammell: And so when they rolled out version 2, we talked about version 2 when they rolled that out. That's right. But they are now having it so that you can take the 3D. viewer that they rolled in in version 2. And now you can export that to Google SketchUp format. So now you can go throw it in your Google SketchUp drawing. And then I searched around a little bit.

Dave Jones: What advantage does that give you? It allows you to rotate it and do... I don't know. Can the 3D tool... How powerful is the 3D tool in the new DesignSpark 2? Is it...

Chris Gammell: I've used it. I've used it. I tried it out there. I got it installed and I tried it out and everything. And you can do 3D viewing and everything. I don't think there was any kind of...

Dave Jones: So what's the advantage of exporting to SketchUp?

Chris Gammell: Well, before you couldn't export it all. So before it was just view it. And now you can actually export to any kind of form. Now you can actually export it. I believe you couldn't actually export the 3D view before. So that alone is a good thing. And then also it's into SketchUp format. Which, you know, if people are using free DesignSpark software, they probably also want to use free SketchUp software. Right. And so by my estimate with that and, you know, now if you have a SketchUp mechanical drawing, you can actually use a different plug-in for the SketchUp now. And you can actually export to a 3D printing format. Awesome. In theory, you know, if you got your boards printed by, like, the Dorkbot PDX guys, you know, for a cheap board with cheap parts on it, and then you 3D printed your actual mechanical segment, I'm guessing you could probably make an entire prototype for less than $100. Right. It might take a lot of work, and it might not be the prettiest thing in the world.

Dave Jones: Oh, okay. Right. I'm getting the thing with this, right? You can export your board in 3D, and then I guess the idea, once you've got that in Google SketchUp, then you can use Google SketchUp as a CAD tool to design your case around that board. Yes. And then export it. Right. Okay. Because there's no point actually importing the board. You can't do anything extra in it in SketchUp.

Chris Gammell: No.

Dave Jones: To the actual board itself, because you've already got to have the 3D parts in the DesignSpark software in the first place for your components. So, you know, it's a bit of a chicken and egg thing there. So, you've got to have those 3D things first. Right. Yeah, there's no backwards compatibility. But then you'll finish board, and then you can use SketchUp to actually design a case or something. Yeah. Right. Okay.

Chris Gammell: And that's all assuming, I mean, like, the SketchUp itself, I think you have to have a pro license to actually export to the really useful formats, like things that...

Dave Jones: That's what I heard, yeah.

Chris Gammell: ...design houses will allow you to use. Yeah. But in terms of 3D printing, there's a plugin called CADSPAN, and you can use that in order to 3D print. So, if you had, like, a MakerBot or something like that, I think that that format... You know, there's a lot of dot three letters, right? Yeah. So, dot XXX, whatever it would be. You can actually then export that to something that a 3D printer can use, and then you could, in theory, print out an enclosure for your circuit board, which you could also do that at home, too. I mean, if you're doing chemical etching, you can do that at home, too, which has got its own bit of coolness. Or if you're doing, not chemical etching, but, you know, like copper routing, which is what I've done before. You ever done routing? You ever done that kind of stuff?

Dave Jones: Not, no, not routing with the actual machines, like the LPKF machines, or is it milling?

Chris Gammell: I guess it's milling, yeah.

Dave Jones: Yeah, well, that's, yeah, that's actually milling, yeah. Yeah.

Chris Gammell: Yeah, it's, I like doing that, because it's, there's no chemicals.

Dave Jones: Yeah, I know, it's not, but it makes a hell of a, yeah, but all the fiberglass, you wouldn't want to breathe it in, all that fiberglass. You kidding me? Shit in the air. I love it. Right.

Chris Gammell: Gets me messed up.

Dave Jones: Down in old Cleveland, Ohio. Yeah, we love that stuff.

Chris Gammell: Then I go take a dip in the Cuyahoga, light myself on fire, yeah, I'm good for the day.

Dave Jones: And I spray myself with DDT.

Chris Gammell: Yep. We run out of pollution here.

Dave Jones: I'm chewing on my grass.

Chris Gammell: Yes. Oh, boy. Let's get more accents coming out of you, Dave.

Dave Jones: Right, no, sorry, that's not all I do. Yeah.

Chris Gammell: It's pretty bad. Yeah, so, but it's a good step forward. I mean, I don't know if this is actually officially from, I mean, DesignSpark announced it. I'm not sure if it's actually through them. That's them and Allied, who actually owns DesignSpark, at least in the US. So, RS is.

Dave Jones: Right, yeah, Allied, RS, yeah, who knows how all that corporate stuff works. Everyone owns everyone else. Yeah. It's crazy. But how much, I don't know what their market penetration is with this DesignSpark. To me, it appears to be almost zip. That's hard to say. I just don't see anyone out there using it. I don't know why. The Eagle's too entrenched.

Chris Gammell: Yeah, it's pretty new, though, too. I mean, like. Yeah, it is pretty new. If they keep developing it.

Dave Jones: And they sort of came in a bit late, you know, sort of.

Chris Gammell: Yeah, I mean, Eagle's been around, what, 15 years? I mean, like, maybe 15 years from now. I mean, like we've said before on here, the DesignSpark stuff's free. So, that's a pretty good starter, you know.

Dave Jones: Yep. And it's free for any size board. Right. And here's the kick. Because I've got to choose a new, well, I want to choose a new PCB package soon. Yes. I want to move away from Altium for my open source stuff. Because, I don't know, I just get the impression that I'm going to be laughed at if I release an open source hardware product. And, oh, here's the design files. They're in Altium.

Speaker ?: Yeah.

Dave Jones: You know?

Chris Gammell: Well, I guess we'll, see you later, Dave.

Speaker ?: Right.

Dave Jones: Yeah, I don't think it actually matters. Because there's very few people, you know, everyone talks about, oh, yeah, open source hardware. And everyone goes out and uses the files. And we've talked about this before. And that's just bullshit. Right? There's only, like, a couple of percent of people who actually will go out there and want to recompile their own source code. And design their own board and all that sort of stuff, you know? Right. Whereas the vast majority of people will just want to buy a kit or something like that. And it's open source because it's cool. And they just know it's open source. And, well, maybe one day they might want to tweak it or something. But, yeah. So, when it comes down to the actual practicality of it, does it actually matter if the files are in Altium format? Probably not, you know? I mean, and we're not talking big designs here, big complicated designs, you know? 20, 30 parts. If you want to lay it out in your own package, it only takes you a few hours. Right. You know? It's not a...

Chris Gammell: Well, scomatics are all there. I mean, eventually...

Dave Jones: Yeah, well, yeah, exactly.

Chris Gammell: And you crank out the Gerbers, too. So, if people actually want to just manufacture themselves... Oh, yeah, yeah, exactly.

Dave Jones: People want to just make their own board. Well, the Gerbers are there. Right. Yeah, that's right.

Chris Gammell: So... Evolutionary design stuff where if you're... If someone wanted to add on to your design because it is open source, then...

Dave Jones: Exactly.

Chris Gammell: So, yeah.

Dave Jones: And, I don't know. Yeah, so please leave in the comments which package do you think I should use? Eagle? Design Spark? Or one of the open source ones? KeyCAD? KeyCAD. KeyCAD? Probably not. Yeah. Yeah, it's actually called KeyCAD. I believe that's how you pronounce it. Yeah. And, uh... Jita? Probably not because it's apparently quite hard to... Yeah, it doesn't have a nice GUI interface. I want a nice, simple, dumbass interface. And I don't care about Linux. Please don't give me the Linux line. Oh, but you can use Eagle on Linux and Windows. I don't give a shit.

Chris Gammell: Really.

Dave Jones: I don't care. I'm sorry.

Chris Gammell: At least you're upfront about it. That's good.

Dave Jones: It really doesn't matter to me. Yeah. Yeah. Eagle? I don't know. I'm just hesitant because there's those limitations. We've had the Free Eagle campaign. The Free Eagle campaign here on the Amp Hour before. It kind of frizzled, though.

Chris Gammell: It frizzled.

Dave Jones: Right. Well, it started again. Free Eagle. Free Eagle. Free Eagle. Now, I just hate their options for doing the thing. Like, I would have to go in and spend... If my board's bigger than, what, 80 by 100 millimeters, which isn't that big, right? Or more than two layers, I've got to spend 500 bucks. Yeah. Right? Which is quite a reasonable chunk of money. And then I'm still limited in size. Are you shitting me?

Chris Gammell: Yeah.

Dave Jones: You know, so if I want to make one long, thin, tiny board, which is less surface area than one big 100 millimeters by 80 millimeters, I've got to pay for the thousand buck package. You know? Yeah. And that's... Yeah. I just... I don't know. I know everyone loves Eagle because it's the tool of choice in the open source hardware industry. But, oh, it's... No, I just don't like their options. So, I don't know.

Chris Gammell: Which one should I choose? Please. Tell me. Yeah, let them know. I was having an interesting conversation on Twitter the other day talking about... So, Robert Davidson... You live your life on Twitter, don't you? I don't live my life on Twitter. Stop. You do too. Please. Please. I get into it sometimes, but I don't live my life on there. Come on now. So, me and Robert Davidson, though, we're talking about open source projects. And he was asking if... He asked me directly if there's any really big ones. And I couldn't think of any. Like any large scale... On the same scale as a Linux where it's collaborative over time and it just kind of keeps building on itself like that. And it doesn't seem like... I told him, I don't think that hardware is as capable of doing something that big because if it's a single board, you get more than three or four designers on it and it's just going to splinter.

Dave Jones: Oh, it just falls to shit. Yeah. Yeah.

Chris Gammell: So, if anything, it would need to be really big, right? It would have to be like an open source telescope.

Dave Jones: Well, it would have to be a subsystem-based, modular-based thing. Yeah, exactly. And they don't work either because they end up being too clunky and expensive and big and just not optimized. Yeah.

Chris Gammell: And that's another thing that I talked about, too, is the fact that if you have to pay for... I mean, with software developers, right? There's time. Obviously, there's time involved in it and that's expensive. But then on top of that, if you have to have a material thing in front of you, right? Yeah, that costs money. So, if every developer then has to pay $500 to buy and build up some boards, then that becomes prohibitive pretty quick, too. So, I don't know. I would be cool, though. I mean, like if there was like an open source MRI or... I mean, because like you said, it would have to be something with a lot of subsystems where people could...

Dave Jones: Well, the holy grail is... Well, the open source hardware industry is an open source hardware pick-and-place machine. Everyone's talking about it, but nobody does it because they realize, oh, shit, it's just too hard. It's too many mechanical things. The mechanical is a killer part, right? Big and complex and massive and expensive and, you know. Well, yeah.

Chris Gammell: A lot of pick-and-place and those kind of three-dimensional moving things is usually stepper motors, right? Isn't that kind of the crux of it, too? So, it's not necessarily... Yeah, yeah. That's right.

Dave Jones: Well, and then the pick-and-place is something. You know, you always see on Hackaday or something, there's always somebody's done their little pick-and-place thing and they get like a vacuum pump from a little fish pond or something and they can pick up one part and they can move it, but...

Chris Gammell: Oh, yeah.

Dave Jones: You know, that's next to useless. You know, you've got to have something that handles the reels, you know, that feeds in the... All that stuff is complicated to feed in the components from reels. There's a reason why these machines cost upwards of $10,000 is because they're complicated. Yeah. In their feeding mechanisms and stuff like that, you know. Yeah. It's not trivial. And then you've got to have vision to do it, you know. You've got to have the vision camera and it's got to do all that sort of stuff. And, oh. When you get down to the fine detail of it and it ain't easy.

Chris Gammell: Yeah.

Dave Jones: So... Well, that's not a reason not to do something, but it's... Oh, no. Of course not. But, you know, it's not something that somebody's going to magically solve overnight. Right. Because, you know, you have to get the components off those reels. Right? There's no point you having to sort all your components onto some little tray yourself manually or onto the bench or individually pick up each one yourself and align it. Yeah.

Chris Gammell: Yeah.

Dave Jones: You know. The whole idea of a pick and place is that you load in the reels, you program your machine, you push the button. End of story. Yep. That's it. You know. A couple other stuff. Anything else is just a toy, really. It's just a time waster. Yeah. Yeah. So you may as well hand solve it.

Chris Gammell: Yeah.

Dave Jones: Or hand pick and place. Sorry. So you, you know, you do your paste stencil and then you just. Right. And you just pop them on there and throw them in the oven. And then you just individually place your. Yeah.

Chris Gammell: Yeah.

Dave Jones: So, I don't know. Somebody prove me wrong, please. But once, like the 3D printer thing, I don't think I'm wrong.

Chris Gammell: Well, and also, too, if people. There's just so many complexities involved. If people know about any large-scale open-source projects, I mean, open-source hardware projects, that would be interesting to me. I mean, I quoted, like, Arduino, but even that, that was defined at once and it's more of the. Oh, that's a trivial project.

Dave Jones: Like, Arduino is a little tiny board with a bunch of software.

Chris Gammell: Right. But it's the. It's been the software that's been the collaborative kind of open-source side of things. Yes, that's right. I couldn't think of any hardware, large-scale hardware stuff that's been open-source and collaborative like that. But maybe there is stuff out there.

Dave Jones: Somebody might pull Chumbie out of their ass or something like that. But even that, that's mostly. I mean, there was people working on that. That's done by a small group of a couple of guys. That's done by. What's his name? Bunny. Bunny Wang.

Speaker ?: I forget his name.

Dave Jones: Chung, Chung, Bunny. Bunny Wang. Bunny Wang. Bunny Wang. Yeah. Yeah. Whatever his name is. Sorry.

Chris Gammell: Yeah.

Dave Jones: Yeah. That's basically done by him and maybe, you know, a couple of core people.

Chris Gammell: His support staff and everything else. Yeah.

Dave Jones: Yeah. And that's pretty much it. So, and they had venture funding for that, I think. Or some sort of funding.

Chris Gammell: Yeah. I don't know. I don't know what it did. Yeah.

Dave Jones: Anyway. Yeah. I don't know. It's just. Yeah. Stuff costs. Software is easy. Because it doesn't cost anything but your time. You know, when people have to actually fork out a thousand bucks for, you know, some prototype bits. Then, yeah. Yeah. They really think twice. Yep. So, I don't know. Is open source hardware, large scale open source hardware projects doomed in that respect? They're just not really possible because no one is going to pony up the money.

Chris Gammell: Right. Well, I mean, or what you do is.

Dave Jones: I'm sure it would have happened by now. Maybe there is a good example. I don't know.

Chris Gammell: Yeah. I would love to hear it. I think maybe more so. You have like the Arduino and the open standard kind of open source projects. Right. Right. And then. Yeah. You leave it up to people to actually do the integration.

Chris Gammell: So.

Dave Jones: Well, maybe. Maybe. Maybe in the quadcopter scene or something like that. You know, the RC. I know there's lots of. Yeah.

Chris Gammell: Yeah. That's true.

Dave Jones: Stuff going on there.

Chris Gammell: But usually those are single board too. Because when you start getting into. When you get more than two or three boards in a system too, it gets expensive quick. You know, like.

Dave Jones: Yep. Well, what would be our definition of a big open source. An open source benchtop oscilloscope. How's that?

Chris Gammell: I don't know. Yeah. But those are usually single board. When they're. When they're. You know, at the hobbyist price level. Yeah.

Dave Jones: They're probably. When it comes down to it. Yeah. You could. They're single board. Single board. Because that's how you save costs. So you're talking a big complex.

Chris Gammell: Yeah.

Dave Jones: System. Well, I don't know. What's a good example? If you've got a good example. Yeah. Let us know.

Chris Gammell: I do not know.

Dave Jones: Or if you've got a real example. Where it's actually happened.

Chris Gammell: Yeah. I hope that would be all of them. Not just like potential.

Dave Jones: And we would want it done by more than just one or two people. With a lot of money on their hands. You know. I want it done by. And a non-commercial venture. Well, not necessarily non-commercial. And a non-commercial venture. Where that. Yeah. Just done for the sheer joy of it. You know.

Chris Gammell: Yeah.

Dave Jones: Yeah.

Chris Gammell: Hmm.

Dave Jones: I don't know. I doubt it.

Chris Gammell: So.

Dave Jones: I'm willing to be proven wrong.

Chris Gammell: Robots. You were talking about pick and place. That's like a robot, right?

Dave Jones: Yeah. Well, yeah. Of course it's a robot.

Chris Gammell: Yeah. So there's a new. There's a Spectrum article about this. There was a. A new robot initiative. At least in the US. And there's this press conference. It's kind of funny, actually. Obama was talking about. One of his jobs is to keep an eye on robots.

Chris Gammell: You might not know this. But one of my responsibilities as commander in chief. Is to keep an eye on robots. And I'm pleased to report that. Robots here. At least seem peaceful. At least for now.

Dave Jones: Cool. All right. That's. That's pretty cool.

Chris Gammell: That was funny. Yeah. Yeah. Yeah. That's funny. Kudos to that speech writer. Because you know that was a speech writer. Okay. Yeah.

Dave Jones: That's good. Yeah. Of course. Yeah. He doesn't write his own shit. I'm sure.

Chris Gammell: So I like. I like the initiative. It wasn't a lot of dough. It's only 70 million dollars. Which I know that's a lot of money. Chump change. Yeah. But in the grand scheme of things. Even with robots. I mean. You could have robots that cost 70 million dollars. Each. Yeah.

Dave Jones: Easy.

Chris Gammell: It's good. Good to start there. But I don't know. The focus is good. But I don't know if it'll actually. Be. This. This isn't going to be the last thing they have to do with it. That they need to keep pushing money towards the robot sector.

Dave Jones: Right.

Chris Gammell: And. But man.

Dave Jones: Well. Isn't. You know. That's a tough push. Because. You know. All these robots have. You know. Killed the car industry for workers. And stuff like that. You know. Yeah. It's. It's a pretty tough sell. To say. I know. I know. It's like. Hey. We need jobs. Let's support robots. But. You know. Take our jobs. Yeah. Yeah. Well.

Chris Gammell: And especially too. Because when you. When you say that. And then there's this uptake of robots. Right. So. So. Like the car manufacturers say. Okay. Well. We're going to start using robots. Because it's a good idea. And we'll have. Like maintenance techs. That need to. Work on the robots. And everything. And we'll be able to produce. X amount more dollars. Whatever. But the problem is then. Then you get like. These low cost manufacturers. That come in. And build decent robots. And those. Those get put in. And apparently. And then at the end. It's just. Robots. In a. U.S. Manufacturing plant. That have been built in China. And. Now they're just building cars locally. So. That's the only downside. But. I don't know. The reason to stand in the way of robots. Because. I think. Yeah. There's a lot of. There's a lot of promise there. And it drives a lot of good technology.

Dave Jones: Did he mention specifics. Of what. Kind of. Are we talking. You know. Personal. Home assistant. Robots. Or.

Chris Gammell: They were talking a lot about like.

Dave Jones: Or just more military shit. Surely it's not military shit. 70 million bucks. Wouldn't even buy you a. No. Spanner. In the military world.

Chris Gammell: Yeah. No. They're talking about manufacturing. Operations. I believe. Because they were talking about. Like a. A line worker. In a manufacturing plant. Then actually teaching a robot. Like a learning robot. Which then learns us. This.

Dave Jones: That learns the person's skill. And then makes them redundant.

Chris Gammell: Well. And then. Well. Then the idea would be. That the person is then. You know. Would watch over many robots. And you can up. Prototyivity and everything. But yeah.

Dave Jones: I'm sorry. This has got fail written all over it.

Chris Gammell: Yeah. Well.

Dave Jones: This campaign has just. Yeah. Yeah.

Chris Gammell: It's tough. I mean. Even. Even in the best case scenario. Right. Where. Okay. Maybe you add robots in it. You don't kill anyone's jobs. Or anything else like that. You just increase productivity. But. Even still. Like. There's only.

Dave Jones: It's kind of like a pyramid effect. Increased productivity. Head count drops. Exactly. Because the company. There is no way out of it.

Chris Gammell: Right.

Dave Jones: Anytime you introduce robots. Or technology. Into any form of. Technology. Into any form of job.

Chris Gammell: Yeah.

Dave Jones: Jobs will go. That's just.

Chris Gammell: Yeah. I mean. Think about like. A garbage collection.

Dave Jones: They don't introduce. The technology to make it more complex. So you need more people to operate.

Chris Gammell: Right. Right.

Dave Jones: No. That's not the goal of any company. That makes money.

Chris Gammell: Yeah.

Dave Jones: So. I. I. I. I. I can't see. A winning move. In this game. Well. I mean.

Chris Gammell: They. I. I think they keep. They keep pushing the fact that. Okay. Well. You can. You know. Have people that are working on robots. And everything else. Like that. And it creates jobs. And yeah.

Dave Jones: Somebody's got to design. And build the robots. And right. And.

Chris Gammell: But. I think the real. Realistic way to look at that. Is that. You know. That. I don't think the robots. To be designed here. Like in the end. You know. Like even. Maybe they'd be designed here. But the robots themselves. Wouldn't be manufactured here. And at that point. Like you know. Yeah. I don't. I don't know what the. End game is. But. I like robots. I think they're cool. So I. I applaud it.

Dave Jones: Fair enough. Yeah. All right.

Chris Gammell: But.

Dave Jones: Robots are cool. Yeah. We will admit that here on the Amp Hour. Yeah. Anything robot based. We'll get mentioned.

Chris Gammell: Yeah. So they're. They're talking about. Here's the list. Advanced manufacturing. Logistics. Services. Transportation. Homeland security. Defense. Medicine. Healthcare. Space exploration. Environmental monitoring. And agriculture. And so basically. That's every job. That people in the U.S. Have right now. McDonald's workers. Farmers. Highway workers. Construction workers. Yep.

Dave Jones: But we're not there yet.

Chris Gammell: So don't worry about it folks.

Dave Jones: We're fine.

Chris Gammell: Yeah. Eat your TV dinners.

Dave Jones: Do the rules of robotics still apply? Oh.

Chris Gammell: The three rules.

Dave Jones: The three. Asimov's. Three rules. Yeah. Still apply. It's been confirmed by Obama. Has it? I don't know. Yeah.

Chris Gammell: Well.

Dave Jones: We have a new. Oh go ahead. We have a new. Let's get away from that.

Chris Gammell: Yeah. Let's run away. We've only got like eight minutes left.

Dave Jones: Seven minutes left.

Chris Gammell: Yeah.

Dave Jones: We have a new segment here on the Amp Hour.

Chris Gammell: We do. We do. I'm excited about this one. So what is it? I don't know. You put it on here. Oh come on. I was going to let you announce it though.

Dave Jones: It's the history of what on this day in. This day in nerd history. In well in nerd. Is it just nerd history or is it electronics? It'll.

Speaker ?: It'll.

Dave Jones: It'll.

Chris Gammell: It'll practically be electronics history. But we'll say nerd history in case there's something really cool.

Dave Jones: I'll say. Yeah. There's something cool. Like. Like. Like the first robot or something.

Chris Gammell: Right. Exactly. Exactly.

Dave Jones: Yeah.

Chris Gammell: Because that would be like mechatronic kind of. Not necessarily just electronics. Right.

Dave Jones: Yeah. Okay.

Chris Gammell: Just cool nerdy shit. Exactly. Yeah. Well. Yeah. Yeah. And electronics bent to it.

Dave Jones: This day in nerd. Is that the official. Yeah. This day in nerd. Title of the segment. This nerd history. This day in nerd. There you go.

Chris Gammell: Yeah. And we get the benefit. The thing that I like about it is we get the benefit that it is simultaneously June 26th here and June 27th there. So.

Dave Jones: Sorry dude. It's actually June 28th here. Oh no. Oh crap.

Chris Gammell: I got my days wrong. Oh no. The good one was on the 26th. Well you know what.

Dave Jones: He screwed up the segment. He can't. Not only can he not get his time zones right. But he's out by. He's now out by complete days. He's lost a lot of people.

Chris Gammell: Oh damn it. It's the 28th here in Sydney. Oh. Well I'm going to see if I can find one now. Oh man. Watch Chris pull a. Yeah. A wiki article on my butt.

Dave Jones: And historical fact out of his ass. Yeah.

Chris Gammell: Here we go. Okay. In real time. Alright. So I'm still going to talk about the 26th one. Because this one was cool. I had started looking at like. You know. People. Like. Definitely one of the coolest things you could do on wiki is. Is kind of look through. The. There's a whole section on like. Electrical engineers. And. And like where they're from. And all this other stuff. And so. I was looking at that at first. And one of the coolest ones that popped up was actually. This guy who's not an electrical engineer. But he's a computer scientist. And his name is. Maurice Wilkes. And so. Obviously one of the things that's going to happen is. That people will pop up when it's their birthday. Or. In this case. Uh. I guess it was their birthday. They also list. List like deaths. So they pop up like that too. Which I guess is just as relevant. But. You know. Not necessarily. But this guy. Maurice Wilkes. Wilkes. Sorry. He's a. A UK. Computer scientist. And he's from back in the days. When computers were actually. You know. Like. Electronics that you pieced together. And like. You know. We're talking like 1945. That's like. That's like when he started. Or. I guess it was 50. 40s and 50s. You know. Really. Really early stuff. So. Um. He's.

Dave Jones: And he's the winner of the. Touring award. The Faraday medal.

Chris Gammell: Oh yeah. Wow. Yeah. Tons of stuff. And you know. Like. Just people that you'd never. I'd never heard of this guy before. Right. I've heard of him. Oh you have? Sorry. That's okay. I'm not too well. Right up on this stuff. But. But basically. He's credited with tons of like. Micro controller type stuff. So he's. He's credited with ideas of. Symbolic labels. Macros. Subroutines. He's looking. There's a picture of him on this. Wiki page. And I'll link it in there. But. You know. Like. Mercury delay lines. Which I'm guessing was used as a memory element. In like. Early computers. And that's just. I mean. That's. That's really cool. You know.

Dave Jones: And he worked on one of the first computers. The. The. EDSAC. Yeah. And. Which is. An acronym for.

Chris Gammell: What is it?

Dave Jones: Uh. The. Electronic delay storage. Automatic calculator. There you go.

Chris Gammell: Yeah. So yeah. I mean. That's a big. That's a big deal. When you start having. Memory. I mean. I'm sure people remember from their. Their early. Digital design days of. Or like. If you're. You know. Learning that stuff in school. One of the biggest parts of a. Any computer. Is just having. Any kind of memory element. Right. So being able to store value. Is really. Really important. And this guy. Had to figure this stuff out.

Dave Jones: Or the architecture. Like the Von Neumann. Architecture. And stuff like that. Yeah. Yeah. Yeah.

Chris Gammell: So yeah. This guy's. Big deal. Definitely cool.

Dave Jones: So that's the.

Chris Gammell: That was. That was June 26th. But I'm.

Dave Jones: That was June 26th. So you were completely out. Oh man. I can't believe I got the day wrong. Two days out dude.

Chris Gammell: Yeah. Sorry.

Dave Jones: That's massive.

Chris Gammell: The one I had for the 27th. And of course. In the future. This would just be two days. And. And only one. If there's nothing good. But. Now.

Dave Jones: Yeah. You have to visualize me here. Just doing the face palm. You know.

Chris Gammell: Yeah.

Dave Jones: Just going. Oh. Shaking my. Slapping my. Forehead. And.

Chris Gammell: Yeah. Anyway. Anyway. Go on. When I do this. What? Whatever man.

Dave Jones: At least I put it on there. All right. Granted. Yeah. If you're going to put it on there. Get it right.

Chris Gammell: Oh yeah. Come on. Yeah. Uh. 27th though. Uh. This is a cool one too. So June 27th. And back in 1895. The. One of the first electronic. Or electric locomotives. Went from Washington to New York. So that's a big deal too. Because that was like the precursor. For a lot of like. Railway systems. And everything else. So not necessarily the first one. But definitely one of the first big ones. Uh. And I'm. We'll. We'll post. You know. An article to electric locomotives. Obviously there's a lot of cool stuff with those. But that's a more. Mechanical kind of thing. So. I don't know. I thought that was cool. And uh. If you want to hear the one I was going to pull out of my butt. Uh. Go for it. Yeah. Uh. Let's see. In 1883. On June 28th. Was the first. Central. Electricity power station. In Europe. So. That was in Milan. That's pretty awesome. Yeah. That's a long time ago. 1883.

Dave Jones: Are there any stats on that? Like. How much power it was. You know.

Chris Gammell: No. Uh. No? I don't think so.

Dave Jones: Or it was just a guy there with. Two bits of wire. And he shorted it together. That was. Yeah. That was the power substation.

Chris Gammell: Yeah. Yeah.

Dave Jones: Or. Or there was just a big knife switch. You know. One of those. Yeah. Yeah.

Chris Gammell: Like in the old. Like Frankenstein movies and everything like that. Yeah. Just thump that down. Yep. Man. 1883 though. That's pretty crazy. And so that was probably.

Dave Jones: That is. That is. Way old.

Chris Gammell: That must have been like a battery based. Like a chemical battery based substation or something. Because. Uh. You know. Tesla had. That was like. Where they had.

Dave Jones: I don't know. Did they have generators? You know. Did they. Have. You know. Generating motors back then.

Chris Gammell: Yeah. I'm trying to think.

Dave Jones: Generating power from motors. I don't know. I don't know my timeline on that.

Chris Gammell: Yeah. When Tesla started doing like the. The AC motor stuff.

Dave Jones: Hmm.

Chris Gammell: Hmm. Didn't. Didn't. Didn't. Didn't get that far back. Yeah.

Dave Jones: This. I think this segment needs more research.

Chris Gammell: Yeah. Let's see. 82. He started working for the. On his. On his. His. Generator stuff. So. Hmm. I don't know if that. Very cool. That might have been then. So. 86. He formed his company. Tesla Electric Lighting and Manufacturing. So that could have been. That could have been one of the first installations out there. So. That's pretty cool. Anyway. Well done. That last one was not fair. Because I totally pulled that one out of my butt. So. But you had to. Because you goofed it up. Because I got the days wrong.

Speaker ?: You screwed it up.

Chris Gammell: You got to fix it. We all know that my. My. My. My deal with time is not very good. I always get the time wrong. Whatever you and I tried to. Whenever there's a time change. Yeah. I always mess it up. So. Bloody daylight saving. I know.

Dave Jones: I know. Right. Yeah. Bloody different countries. Yeah. It's a. It's an American thing. You know. Outside the US doesn't exist. Outside the US.

Chris Gammell: Outside my head doesn't really exist. Most of the days for me. That's just. That's just ego. And cluelessness. And lack of attention. So. Yeah. How. Speaking of.

Dave Jones: Sounds familiar. Speaking of time.

Chris Gammell: How are we doing on our. How are we doing on our amp hour? Are we. Nah.

Dave Jones: Capacity's up. One hour. Is it? 21 seconds. Yep. Ah.

Chris Gammell: Damn.

Dave Jones: We're up. But then again. We always go over. Do we have anything extra.

Speaker ?: To put in.

Chris Gammell: That last tidbit. Yeah. Um.

Dave Jones: Because we always throw. We. We go all the hours up. But. We'll just throw this in.

Chris Gammell: Here's one crappy one. So there's. This is. This is not electronics. Yeah.

Dave Jones: Let's throw on a shit one.

Chris Gammell: Yeah. This is not electronics related. But I saw this article. This week. On. This company. This company. Is saving Facebook data. From everybody. In order to. For. Future companies. Looking at your. Like. So. So. Say. Dave. You post something on Facebook. Like. Oh. I. You know. Chris is the biggest asshole in the world. And. And. You know. Like. I've never worked for him. Yeah. And then I go to a company. Or I start hiring for a job. And. And I'm like. Oh. Dave Jones seems like a good candidate. Can you do. You know. I go to a firm. And say. Can you do some background research. This company. Saving everybody's data. Apparently. I don't know how.

Dave Jones: Right. So. They just suck it off. This is a third party company. Right. Yeah.

Chris Gammell: Yeah. So. They receive. FTC approval. Basically. In order to. To screen these posts.

Dave Jones: And. Of course. The government gave it to them. Yeah.

Chris Gammell: Yeah.

Dave Jones: Fantastic. Because. Facebook is not Google indexable. Is it?

Chris Gammell: I don't. I think top level. Like. Public stuff is.

Speaker ?: Like.

Chris Gammell: Like. Pages.

Dave Jones: Public stuff. But. Yeah. Obviously. Well. They can't suck the private stuff. Surely.

Chris Gammell: Right.

Dave Jones: They. Surely. They cannot. Please tell me. They're not sucking the private stuff.

Chris Gammell: I don't think so. But. Either way.

Dave Jones: That's only between you and your friends.

Chris Gammell: Yeah. Either way. That sucks. Although. So. Real quick. Because. I think this. We should talk about this. Before it becomes passe. But. I'm sure we'll be able to talk about it next week. More or two. But. And. This is totally different than the Facebook thing. US is switching patent systems. So it just got passed in the house. So. Basically though. It's just switching. One train wreck to another. Yeah. Right. All right.

Dave Jones: Shuffling the deck. Shuffling the deck chairs on the Titanic. Yeah. Right. Name year. Yeah. Cliché. Yeah.

Chris Gammell: Yeah. The. I think we'll probably hear more about it next week. Because it's not actually signed into law yet. But basically. The US is talking about going from. First to file. First to invent. To first to file. Like the rest of the. The rest of the world does. So. Right. There's that.

Dave Jones: Which means we don't need any more lab books.

Chris Gammell: Yes. That is nice.

Dave Jones: And if you're not aware. If you've ever worked in a big company. Or something like that. You're probably familiar with the engineering lab book. Everything you do. Yeah. You have to notate it. You have to carry around this lab book. And you have to write everything in it. It proves that you did it. And you have to date each page. And you have to have it like.

Chris Gammell: Someone understands it. And they note it. And whatever. Sign it.

Dave Jones: Yeah. So it just proves that. Oh. Sign in. We didn't sign ours. But. Yeah. We just. I know. Sometimes you would sign it yourself. Oh. Okay. You wouldn't have to have a witness. Or anything like that. Okay. Maybe if it was something really super duper important. Wow. I just came up with the next world changing widget. Yeah. Yeah. You would get 20 people to authorize that it was done on this date.

Dave Jones: Yep.

Chris Gammell: And then it never goes through. Stuff like that.

Dave Jones: Yeah. The engineering lab. But I can remember that. The company I used to work for. We. Yeah. They used to fly halfway across the country. For a day. And then come back. You know. To our. Other. Facility over there. Uh huh. And so they used to. Like. Grab their engineering. Their red engineering notebook. Jump in a cab. Hop on the plane. Go fly halfway across the country. Go to a meeting. Come back. And they'd. All they'd carry around is their red engineering lab book. You know. That's crazy. I know.

Chris Gammell: Yeah. So that's.

Dave Jones: It's insane. Anyway. Yes. Ah. So I'm sure we'll hear more about that.

Chris Gammell: But I thought that was interesting. I don't know if it'll. It still has to pass and everything else. And it's still just the US. But.

Dave Jones: Who cares. It's still going to be a shit system. Yeah. Yeah. That's exactly right. Does it matter? Yeah. Really? Still patents. Yeah.

Chris Gammell: Yep. Still got to defend them in court and everything.

Dave Jones: Yep.

Chris Gammell: All right. And that involves lawyers. Yeah. Yep. And we needn't say any more. Nope. But we will say more next week on the Amp Hour. As we always do. Yeah. We're here every week. Yeah. We'll be back then. For twice the fun. Yeah. We'll talk to you guys then. See ya. Bye.

Speaker ?: Thank you.
