Remember those? Looking for copy of the schematic for their old kit, want to adapt it for rear wipers for one of my projects.

You could use a 555 timer to do the variable wiper delay function.

Hi, Tim. Yea with the 555, but the heathkit used a simple R-C circuit that was pretty bulletproof, and this is for the rear wiper in my toyota SW and for rear wipers in my '66 pamel truck barn doors, and I want to vary the time sometimes up to maybe 2 minutes or so.
