Wiring diagram

A project log for DIY Spin Coater

A spin coater is used to spread a thin layer of liquid on a flat surface to a very precise thickness, like photoresist on a PCB.

It's great to see several people have built their own versions based on my design. If you've built your own, please send me a picture, I'd love to see it!

I've gotten several requests for a wiring diagram, so here it is. I had naively thought the wiring is self-explanatory, but considering how long it took me to make this diagram, I was probably wrong. Please forgive the amateurish drawing. I hope it helps.

Note that I did not hook up the ESC's GND serial connection. There's no good reason for this, I just ran out of space. It works fine, but you could hook it up if you want to.
