Default Re: Quick n dirty coil winder

I have done a rebuild... yes.. so soon.. LOL.. I upped the diameter of the shafts to 6.5mm and added more bushes...The original problem was a total dis assy of the shaft holding the bobbin....so I cut the shaft.. added more bearings...fitted a turns counter.
The turns counter I bought from ebay...it is driven from a mini magnet on the outer of the handle drum, and a reed switch below. The counter was modified to accept an external battery, as the battery removal was inconvenient. The only real problem is that the counter clicks "UP" for every rotation.. be it clock or anti clockwise.... thus I need to re design a counter using a PIC... and two magnets to detect direction of rotation.
