Following the sub-discussion on the Screwdriver holder topic ( regarding Super-PID, it reminded me of RPM sensors using arduino and IR. And followng that line, I saw this instructable where the author makes an arduino tachometer for his CNC. Looks to me like there should be a way to evolve it to a super-pid like ArduinoPID…

Thoughts ?


Absolutely. I’m a software guy, and electronics don’t bother me, so to me, 99% of the problem is just sensing the bit. If it’s sensed, then the rest is easy.

Well, I still haven’t tested out that speed control I bought from tindie (I swear it is on my short list of things to do). Combine the two and we have what we need.
