Drill Speed Controller for 12V PCB Drill (Query).

[Yorkie]

Thanks for reading the thread guys, and for your helpful comments.

I've now tidied up the layout a little, and have finished the artwork for the PCB mask, which I've printed onto film, ready for exposing, developing and etching, when I've sprayed a piece of PCB with UV lacquer.

I've attached the updated component overlay and PCB layout for anyone who is interested.

I'll update the thread when I've made a bit more progress.
