I'm a Guitar Pickup Maker, trying to automate my winding machines- SOS HELP ..

Im Don Mare of Long Beach CA. <snip>

14 years of 1950's style vintage Coil winding of Fender Guitar 1950s guitar pickup tone.

its time to get with the 2000's

Ive been winding coils by hand for 14 years

I want to develop a automated machine that does what i do by hand.

I'll be asking some question - and hope someone can help me because Im stuck in the mud..

Im not at all a EE -- my main part i seek is a Countdown turn counter - that has 6 digits and when it reachs Zero it cuts the power to two AC motors.
I just cant seem to pin point what to buy?

thanks Don

looking for a six digit turn counter that runs from my Optical looking wheel and sensor that's already in use.

the new counter needs to count down to zero then cause motors to turn Off.

and there's no software development required.
How do you do that. or How do you not do code?

Next. When winding 1000 turns there is no problem with +/- 1. My high power transformers have numbers line 10 and there can not be any error. My counters count tenths of a turn. That way some slippage in the shaft encoder is not as much of a problem. (some times I need to back up a little and fix a bump in the winding and then go on) A home made shaft encoder struggles with that.

Some time ago I tried to build one. Used for that the main board of an Epson printer. I even replaced the micro with one from 18F family to do my own stunts.

I implemented the winding action leaving the back and forth displacement of the fitting guiding the wire, unimplemented for the lack of a stepper with better resolution.

Tested it for maybe 3 hours. A disaster trying to guide the wire manually through hundred of turns each time. An aching back was enough.
