CIMG7792 A pedal-powered circular see-saw: top seat at the Maker Faire 2007.
A hybrid of a see-saw and a tiny Ferris wheel, this contraption is set in motion by the two riders pedaling. The seats rise and descend in a circular manner. As before, I had to wonder what would happen if one of the riders stopped pedaling, or pedaled out-of-phase, or backwards, or something. Here it is on video.
Maker Faire was a two-day event that celebrated arts, crafts, engineering, science projects and the Do-It-Yourself (DIY) mindset. It took place in Austin, Texas in October 2007.
