Back in September, I wrote a piece on Zach Debord’s awesome Twin-Engine Solarroller which uses a variation on the Type 1 Solar Engine I’ve written about in my BEAM Robots series for MAKE. I asked Zach to collaborate with me on another Street Tech Feature, this one on Vibrobots, a type of BEAMbot that uses the same type of Solar Engine (with a Flashing LED as a voltage trigger), is easy to build, and really entertaining to watch.
