Tune in to Make: Talk radio episode #004

I’ve enjoyed listening to the first three shows a lot, and now I get to do some talking! I’ll be chatting with Dale, Gareth, and Keith today, Friday March 27th at 12 noon PST.

From the announcement:

On this week’s Make: Talk, we’ll be chatting with John Edgar Park, host of the Makers Workshop segment of Make: television. John will be talking to us about the show and about his articles in MAKE, especially the Florence Siphon Coffee Brewer from Volume 17. John is also a “character mechanic” for Disney and was responsible for the hamster physics in the movie Bolt. Character mechanic? Hamster physics? And I thought I had a cool job!

Mark is on the road this week, so Dale and I will be joined in the virtual studio by Keith Hammond, MAKE magazine’s Copy Chief and our liaison with Make: television. Be sure to call in to talk with us and for prizes that we’ll be giving away during the show!

Arduino solenoid test

I’m working on a project with my friend Usman Muzaffar that involves solenoids. Here’s my first test of a little relay board I built sending 12V to the solenoid based on a 5V signal coming from the Arduino.

This is an interesting set of photos from the U.S. Army medical archives. http://www.flickr.com/photos/medicalmuseum/
No disrespect intended to the soldier amputee in this photo, but he looks like a pretty awesome super-villain.
