For the last few years, I have repeatedly and frequently needed to wind a wire around a thing. From making RFID antenna to transformers. I switched job about 6 months ago and naively thought my winding days were over. However, I was wrong. By some freak accident, I’m back winding wire onto ferrite rods. This time though I need to make some whopping 1H inductors. I’m not going to sit here and wind a thousand turns by hand, not while I have a stepper motor, a microcontroller and a makespace next door.

After a couple of hours on Fusion360 I had a design and I was off to laser cut it. Doesn’t look too bad. The rest of the parts should arrive tomorrow when I can finish this beast.
