My favorite interaction was a youngster approaching Jesse Hemminger’s Sauerkraut Powered Robot display at the Pittsburgh Mini Maker Faire, getting a whiff, throwing his hand up to cover his mouth and then ran off instantly.

    Funny!

    Can you post a video of these puppies in action?  They look like fun!

        Very cool.  Thanks for sharing a video of them in action.  I assume you’ve got ‘solar-bot’ type circuits collecting power.  Nice synthesis.

        I love the orange one when it fits!

          Oh yeah, I was going to post info about that too. I’m using beam robotics circuits from: 
          http://www.solarbotics.net/library/circuits/se_t1.html

          The first robot you see in the video is actually a kit from Solarbotics.com
          http://www.solarbotics.com/products/sym1381/

          I just removed the solar panel and connected the Sauerkraut Batteries. I also attached pencil lead so it would draw me a picture.

          The next one you see in the video is my own creation, I just bought the individual components from Solarbotics.com, added a limit switch and extra motor to the Miller Engine circuit design from Solarbotics.net, and freeform soldered it together into what I think looks like a little crustacean. The limit switch makes it a wall following bot by simply switching between the two motors.

          The orange robot is a Hexbug Ant that I circuit bent by removing the batteries and adding a Miller Engine so it could be powered by the Sauerkraut. This one has a much much larger capacitor (.35 F instead of .0047 F) so it takes much longer to charge up, but when it goes it also goes for much longer.

    Strictly-speaking, it’s not really sauerkraut-powered. the sauerkraut is just the ion path and the energy comes from the oxidation of the metal plates. Great work, but you need to pick a more kid-friendly electrolyte next time! =)

      Yeah, I also realized that they are not technically sauerkraut powered, and wrote about that on my project blog:http://jessehemminger.blogspot.com/2011/03/its-metaphor.html
