Spinnerator fidget spinner generator with LEDs. Shows kids how electricity is generated.
Works best in dark. I only had 30 AWG wire, but thinner should provide more turns, with a higher potential to the LEDs.
Additional parts:
Qty 3, three-pack of 18 mm x3 mm neodynium disc magnets from Home Depot
Qty 3, red T-1 3/4 (5 mm) LED
30 AWG or smaller magnet wire
Skateboard bearing
Adhesive (5 minute epoxy)
Tools:
Nut and bolt to secure coil form for winding
Hand drill
Solder and iron
