We’re joined once again from our friend Jeff Keyzer of MightyOhm.com, calling in from NYC. He is wrapping up weeks of travel, most recently at the Open Hardware Summit and the World Maker Faire. Welcome once again Jeff!

  • Chris is a married man! Sorry all you throngs of lady-listeners to The Amp Hour, this nerd is taken! Would you marry an engineer?
  • Chris will also be in Boston for the coming week. If you’re around give him a shout!
  • Dave just got back from his trip to Melbourne. He saw lots of great stuff, to be explained in future videos. But check out his latest video about cell phone SAR testing.
  • Also on the schedule was an interview with Colin Mitchell of Talking Electronics.
  • Great presentations from Bunnie Huang about the future of Open Hardware and from Amanda “w0z” Wozniak about the importance of documentation.
  • Some other captured videos are available on the side bar of the OHS ustream page.
  • Shoutout: A short news-based podcast called “This Week in Engineering” popped onto Chris’ radar.
  • Jeff also mentioned the Open Source Hardware Junkies podcast, which neither Chris nor Dave knew about.
  • Chris was at the ICSCRM conference last week, one focused on GaN and SiC devices. Pretty cool future for power and switching applications!
  • Jeff mentioned the importance of these more exotic, non-standard materials entering the market, like when Dr Shuji Nakamura used GaN to create a blue light LED.
  • Chip of the Week: Well, really package of the week. The International Rectifier DirectFET2 package is really cool! It’s a flip-chip die in a tiny metal can that allows heat sinking on both the top and the bottom.
  • Listener Ben Rampling sent in an amazing video for our Shonky Product of the Week segment. The guy in the video is claiming your being bombarded with deadly radiation, as shown on his 0-1KHz FFT plot that zeroes out when he puts his feet on a grounded surface and his wrist on a grounded mouse pad. A must watch for ridiculous product claims!

  2. “Twenty four volts. That is the highest number I have ever seen!”

    That guy with the hair is awesome. I wish I had a $15 RadioShack meter so I could indisputably prove stuff like this as well.

  3. Wow, the site of the “cool-looking-dude” is a gold mine of shonky product. And video presentation of them, with so much science and true fact….. must see!

  4. The “holographic” balance thing is called “Power Balance”. I have seem some people using them in the Dominican Republic. It’s just a placebo effect. Bullshit.

  8. this talk about open source hardware license is pointless. What is open is open and period. Do I have to license my 555 astable oscilator board? What a ridiculous talk.
