How to Make DIY Universal Coil Winding Machine with Turn Counter

Описание к видео How to Make DIY Universal Coil Winding Machine with Turn Counter

An old manual hand drill lying around can be used as a universal coil winder, so can be an old calculator as turn counter!

So you can wind and rewind coils to whatever project you are making, be it a tattoo machine, hifi speakers, transformers, converters, guitar pickups, electric motor rewinding, maglev train models, Bedini, doorbells, security alarms, electromagnetic locks, low pass filters, crossovers, subwoofer frequency dividers, crossover inductor coil etc...

You'll need:
an old manual hand drill
old calculator
reed switch magnetic contacts
extra time
