The Solarbotics Solar Marble Machine

Solarbotics, have added a solar cell with a smart circuit to this clever marble machine. The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the gear wheel move, which eventually drops the marble down the spiral. In sunlight, the motor will pulse every few seconds, and  drop a ball every minute. In indoor light, motor pulses will drop to every few minutes (be patient)! if you are not, then you can use the hand crank and see the marble drop.

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.
