Gyroscope

thingiverse

A compact, battery-driven gyroscope utilizes a gyro mechanism and is powered by 4 button cells. A video demonstration is available at http://www.youtube.com/watch?v=Ov5WVhhIdWo. Additionally, a DXF file for lasercutting is provided, with a suggested material thickness of 5mm; however, pivot holes need drilling. To balance the motor and battery weights, use spare hardware like nuts and washers. Assemble the flywheel and frame by inserting nails into designated points, gluing them in place, and trimming excess. Attach the flywheel to the motor, strap the motor and batteries to an inner disc with counterweights, wire one motor lead to the batteries, and assemble the frame using indentations for nail points. The remaining motor lead is wired to the batteries. Fine-tuning of counterweight placement can be challenging, while wiring involves wedging a lead against battery ends. The motor used was from a toy gearmotor assembly (Solarbotics GM17) with its pinion gear left intact for easier mounting.
