I am attempting to adapt a GM cruise control to my street rod. I have a pulse generator driven by the speedometer cable at 8,000 pulses per mile which is roughly eqivalent to 132 hz at 60 mph and between +2.v and -2..v ac sine wave. I need to divide this in half so I get 66 hz at 60 mph or 4000 ppm which is what the cruise expects. Attached is a circuit developed by ED Raether that I found on the internet (hope he doesn't mind me reposting in this forum) where he adapted a 40,000 ppm generator to the gm cruise. Would anybody be kind enought to take a stab at modifying it so it would work with the 8000 ppm sine wave I have.
Thanks in advance. Feel free to ask me further questions if clarification is needed.
