Re: AC Dimmer

Yes. I think I can manage to mill 1206, but I wanted to mill the PLCC48 for a STM32 and its virtually impossible on my cheap CNC machine

Re: AC Dimmer

OK.

I tried that but I did not get good results. However I think it would be OK for a board like that which does not have very small SMD components
