This miniature Marble Machine makes the perfect desktop distraction.


Product #: MKSB027

Solarbotics has partnered with Martin Raynsford of the '365 Laser Cut Projects in 365 Days' to bring you his popular project the Solar Powered Marble Machine Kit. 


The new and improved PCB board takes the energy 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)! No patience? You can use the hand crank and see the marble drop.


Note: this 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.
