Description
This is a 3D printable electric generator / dynamo with a built in gearbox.
And to be honest, I didn't expect this to be so powerful!
What you need:
-16 coils (Max: 31x32x10 mm or 27x27x25 mm) The ones I used: https://www.digikey.com/en/products/detail/triad-magnetics/FS20-055-C2/3986439
-16 neodymium magnets (Max: 10x10x5 mm)
-Wire
-7 bearings (Diameter: 22mm, Height: 7mm, Hole diameter: 8mm (The ones in fidget spinners :) )), Or you can use the bearing replacements.
-Glue will also be needed when assembling (Super glue or hot glue works)
No soldering required!
This generator can also be built with the bigger gearbox, where you would need 7 more bearings/replacements
