    Coil winding tip - use old calculator to add

    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 !!!

      RE: calculator

      Sweet. very useful. Good RPM calculator too.
      See my experiments here...

      You do not have to prove something for it to be true. However, you do have to prove something for others to believe it true.

        For those of you who found this didn't work on your calculator, try entering "1++" before triggering the equals key, and this will work fine. Good idea for coil wrap counting, Dodeca. Thanks for your post.

          If you are trying to measure how fast the wheel turns ... then the " debounce circuit " will prevent multiple fast reed switch closure on a calculator . But I think it's faster than the daftmans mechanical method .

          To measure RPM ...

          I might try a magnet mounted on the wheel that passes by a small coil once per revolution going back to the computer sound card ( mic input ).

          It might work ??? 4 free

            Ive seen this also done with a pedometer. Just pop it open and it makes sense. Micro switch activated by a cam or reed/magnet.....
