Marble Motion, enabled by Solarengine technology that keeps on moving even in low indoor light! Description
Here's the new video of the complete Marble Machine in action:
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
