Hello All

I am putting together a coil winding set up with a variable speed reversing DC motor. On the mount where the new coil is being wound I have a magnet. And below that a simple reed switch wired to the "equals" contacts on a old calculator I never use. When you are ready to count windings ... turn on the calculator and enter on the keypad " 1 + " . And every full rotation will press "equals" button and that's it folks. Simple !!!
