The Solarbotics Solar Marble Machine
Balls ride up, balls roll down, powered by Solar Engine technology for use even indoors!
Our Solarengine circuit stores the light from the solar cell, and releases it in an occasional pulse that drives the mechanics
In sunlight, the motor will pulse every few seconds, and drop a ball every half minute. In indoor light, motor pulses decrease to every few minutes (be patient). But you can always use the hand crank to manually advance the marble wheel.
The kit contains all the parts to build your own Marble Machine, except for tools: you will need a soldering iron, Philips #1 screwdriver and a tiny bit of glue. The wooden parts come in handy panels with additional instructions.
