Shoutouts
- Dave's $50 shootout is cited in Adafruit now carrying the Extech meter. Cool! There's also mention of it on extech site.
- NPR did a piece covering hackerspaces. Likely many have heard about it , but it's good coverage of the burgeoning trend.
- All About Circuits is a great resource if you've never seen it. Huge forum, great open textbook.
Discussion Points
- Is it feasible to open a fab that only makes discontinued chips. Places like Rochester Electronics and Lansdale both do it, but at very high cost.
- Dave says there are still stores in Australia that sell electronics like Jaycar and Altronics. Chris doesn't know of any in Ohio. Jaycar even sponsor a big Rugby League Football team
- However, Freetronix posted to their Twitter that they will get their gear into some shops, it's likely the ones listed above. Congrats!
Where to buy stuff online? If there are no more storefront eShops, where to go?
- Elexp, as suggested by LadyAda
- Electronics Goldmine
- Futurlec
- Electronics Surplus (in Cleveland)
- BG Micro
- Alltronics
- Many thanks to Sam of Maker's Alliance in Cleveland! Great suggestions!
An EEVBlog user got a super nice Tek scope off Craigslist. Should he sell it, buy a cheaper one and profit?
Different parts of the world have standard NPN/PNP parts (as well as other types of parts).
- North America is the 2N3904/2N3906
- Europe and Australia is the BC547/BC548
- Japan is 2SC1815
- Thanks to Wikipedia for the info about transistors (don't forget to donate while you're there!)
Chris has found the value of plotting realistic timelines in his projects and also trying to figure out the all important "requirements" for the project, one of Jack Ganssle's favorite topics in his writing.
Dave continues to work on his secret project but might trot out the demo soon.

New Segment: Workplace of the Week!
- We'll have a dedicated page to workplace of the week where we keep track of people that write to us.
- Send in your pictures, what kind of work you do and anything else you'd like to tell us about your work place. The stranger the better!
- This week was inadvertently The Riverside Robotics Class from Chattaroy Washington!
  - They had written to Dave previously and became the first chosen. We'll post pictures later if we get any from them. They are a HS electronics club that works on robotics! Awesome to see HS students working with electronics.
- Interested in being the next workplace of the week? Let us know!

Thanks for listening!
