- Logic analyzers use state analysis and timing analysis. They also can do state triggering.
- Ask the listeners: What is the craziest errata you've ever seen?
- Dave went and picked up 100 kg of Electronics Australia magazines.
- Chris still gets tripped up by rules of thumb for the metric system. XKCD has a brilliant chart of different ways of remembering amounts.
- The CSIRO are trying out a new wireless data system that can transmit over 10 Gbps!
- They also are the rightful inventors of WiFi and receive royalty checks for people that use the standard.
- We don't like companies that only defend patents (like Intellectual Ventures) but if they roll the money back into research, that's ok!
- Dave was watching a TV special on a software lock technology company that took on Microsoft...and won! (well, settled)
- OSHW Association was announced recently. They will be a registered 501c3 corporation.
- Followup from the other week: The Raspberry Pi made it through EMC testing and will be manufactured and sold now. Andrew Back does a first look at a beta unit, connecting it up to a vintage CRT monitor.
- What other hobbies have home labs? Most chemists are afraid to have labs at home because they might be accused of devious behavior.
- Though they still have a ways to go, plastic electronics are getting lower impedance and are still printable.
- Molex has mini-fit crimp terminals that have a 1500 mating cycles at 13 amps!
- What are your connector design considerations?
- Chip of the Week:
- The Linear Technology LTC4366 (yes, LT again). It's a chip that can detect and protect against incoming surges. It's programmable for time and over voltages. Plus it can float on your rails! Cool!

10 Mbps? Thats like so yesterday.
The linked article says 10 Gbps. I think thats more noteworthy. ;)
Here is a news article:

Could it be that this is a mix-up with the term "Improvised explosive devices" (IEDs)? Airport security e.g. might worry about electronic circuitry being part of an improvised explosive device and might want to investigate further, but I doubt they will refuse people from traveling with some circuit boards as long as they are just not connected to explosives.
Am I wrong? Is security staff really banning electronics from everywhere or is it just that Dave happened to misinterpret the abbreviation IED as referring to improvised electronic devices rather than to improvised explosive devices?

Boston blowing up blinky led banners? plenty of those
Uneducated retards in position of authority = where we are now.
chemist lab and sticking to the man? dont think so
just google "Toronto's G20 hacker". Hobby rockets = jail time.
Still, is "improvized electronic device" an established term?
Hedy's Folly: The Life and Breakthrough Inventions of Hedy Lamarr, the Most Beautiful Woman in the World
I just listened to this audiobook and really enjoyed it. There is a fair amount of information about player pianos and how ideas from the player piano provided one possible implementation for switching control frequencies of a radio guided torpedo - WWII era. cool stuff.
And they settled too, which means they knew they were going to lose. And these are not companies that just settle willy-nilly.
This is a quote from Bill Gates about patents from 1991:
"If people had understood how patents would be granted when most of today's ideas were invented, and had taken out patents, the industry would be at a complete standstill today.… The solution to this is patent exchanges with large companies and patenting as much as we can. " (from http://en.wikiquote.org/wiki/Bill_Gates)
The one who pays the bill is the small companies and the consumer.
Maybe not, but these big companies have an infinite amount of money and legal resources, and they usually do not settle unless they are pretty darn certain they are going to lose the case.
Their modus-operandi in patent suits is usually never to settle, just keep throwing money and the best lawyers at it and stalling, until the smaller company goes bankrupt.

The best one is 14 - Certain combinations of code sequence, code placement, VDD, F OSC and temperature may
cause a corrupted read of fetched instructions or
data.
Whoops!!
"At certain frequencies and voltages, the store program memory (SPM) instruction may fail. Problem Fix/Workaround: Avoid using the SPM instruction."
You need a series element to either shut down (if acceptable) or regulate through the surge. You precede that with higher voltage tranzorbs and/or some capacitance to protect the series element from high voltage low energy spikes.
The LTC4366 looks interesting. I would be more excited if it included a charge pump and level translator to drive an N channel MOSFET.

It gives a catalog feel to the regular dk interface. A bit buggy and not for full time use, but greasemonkey makes it easy to turn on an off at will. Works really well on connectors, especially if you can narrow down your search to 250 or less parts(the arbitrary limit of picture display in this version). Make sure you search "in stock" to get full effect.
The CSIRO!
Dave's first VBlog talks about the patten suit of 802.11!
Same thing you're talking about today. Dave, you've come a long way.
Best of luck,
