Hi folks,
Does anybody know where I can pick up a simple, pre-made LCD photo-interrupter tachometer?
I've seen them once or twice over the years but can't find them available now.
I want to hook one up to my lathe as it's hard to know the spindle speed now that I have a VFD. I have a laser tacho but want to wire up a permanent solution.
Cheers,
Rich
