    Thought this might be an interesting first project, but my knowledge is very basic.

    A 12v old (1988) boat speed indicator with its paddle wheel sensor. I have a new display which can read the old paddle wheel but interprets the speed at close to twice the proper value. Calibration on the new display is limited to about 15%. I guess the paddle wheel sends a signal each time a paddle induces a current.

    I think if I can find a way to lose every other signal from the paddle wheel then I can use the two together. Such a circuit doesn't sound too complex - is this something I can buy? Otherwise could you give me some pointers, please?
