The Solarbotics Marble Machine Kit - Solar Edition

The fun of a Marble Machine, miniaturized for your desk, solar powered!
In stock
$33.00

Marble Motion, enabled by Solarengine technology that keeps on moving even in indoor incandescent light!

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. (Or, perhaps you might want to get the battery powered version instead.)

The kit contains all the parts to build your own mini 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.
