Inductor coil winder

I finished the coil winder a month or so ago and since I’ve used it a great deal. It was definitely worth the effort to build. It lets me make 1500 turn inductors in a matter of minutes. Coupled with Makespace’s Form1 to print coil formers, the results started to look pretty professional.

 

I ended up driving the stepper from an STM32 Nucleo F030. It is programmed so a push of the user tact switch will trigger an interrupt and the board will micro-step the motor for 100 revolutions. This gives a bit more control than just sending it off on the whole 1500 turns at once. Using the Nucleo board also meant I didn’t have to add a separate button, as I would have using an Arduino.
