- We’ll be interviewing Øyvind Janbu, the CTO and co-founder of Energy Micro next week! We’ll have a separate post for asking him questions.
- Chris will be speaking at the Bay Area Maker Faire. If you’re going to be there, find a comfy chair and prepare for a snoozefest 😉
- Second reminder for applying to the Lemnos Labs hardware incubator program, which will be closing soon.
- Our friend Alan Wolke did a really fun tour of his shop…through the screen of his oscilloscope! Lots of fun!
- Dave has finally figured out his MakerBot…with some help from his friends and by reading the (friggin) manual.
[tube]http://www.youtube.com/watch?v=omtmtJelm9M[/tube] - Chris brings up a fun direct ink resist print using a vintage Epson printer. Great quality!
- Sometimes process adjustments are necessary to get more life out of a process node. Chris mentioned an Engineer Blogs post about Photolithography, but that actually doesn’t talk about the interference. There is a slide set from the University of Waterloo that does a good job explaining this process.
- Intel continues to win by being the bleeding edge process company. Will be interesting to see if they get into the foundry business.
- Dave mentioned the recently announced scandal involving Silverbrook in Australia, who have failed to produce output for many many years.
- Apparently it’s possible to print super caps with a Laser Scribe DVD burner:
[tube]http://www.youtube.com/watch?v=_oEFwyoWKXo[/tube] - DigiKey instituted a visual catalog…online! Finally! Have they been listening to the show??
- LEDs that are going to be lighting up homes and workplaces almost were not possible. A researcher in the field explains the small margin on the bandgap required.
- Dave mentions Gazumping, which Chris had never heard of.
- Relays are a simple and yet crucial part of electronics. Chris was looking for cheap and small ones and was shown these from Omron. However, they didn’t fit the bill. Instead, we found out about new research into relay-like devices….on silicon! Wow!
Don’t forget to subscribe to us! We suggested Miro (Dave’s favorite for the desktop) and BeyondPod (Chris’s favorite for his Android phone). There are lots of great options out there, we just want to make sure you hear about new shows when they are posted! Thanks for subscribing!
Thanks for the mention! I’ll be listening to the podcast tomorrow…
Dave: have you seen these parts I printed at dec 2011.. I didn’t design them, those desings are from thingiverse.
Just wanted to tell you that quite complex and accurate parts can be made with sub 1000usb printer.

Great show guys, and it looks like you have solved your interruption problem.
Hi Chris and Dave
(Chris gets a mention first as alphabetically his name comes first)
Just to let you know that I listen to the show each week.
I work from home so I just download it in real time and listen whilst I plug away on the keyboard
I have an active interest in electronics (I’m an EE, but not doing it for a living now, but not retired)
I’ve picked up lots of great tips from the shows.
keep up the great work – even if I don’t show up in the stats
What happened to the question submission post for Øyvind Janbu? It was up for a while and then disappeared.
They already recorded the show with him last night, and put it in the can for release next week.
Oh I see.
Though I would have preferred it if they left the post up and just added a message saying “We are no longer accepting questions”.
Because now there is no longer any original record of the questions that people asked.
We still have it, I can put it back up later. Just don’t want to disappoint people who didn’t get in in time. Should have put it up earlier, sorry everyone!
Hi Chris,
I am pretty sure the MEMS relays are electrostatically actuated instead of magentically. Electrostatic switching makes it not succeptible to magnetic fields (electric fields are easy to shield) and dramatically reduces the current consumption (essentially only leakage current). For a traditional relay it would require impractically large voltages and have too little pull force, but it is a great match for MEMS devices.
I use a lot relays in my business and found this discussion interesting. Relays are an important and are under appreciated for all they do in designs.
How about expanding the show to The Amp Hour – 90 Minuets ?
FYI
Mouser (the wave Dave pronounced it) is the electronics supply house.
Mauser (the way you pronounced it) is a German gun manufacturer. One of the oldest and best in the world.
Don’t tell Dave. He just doesn’t get us yanks and our guns. LOL
