    RFC: Electronic Solution for Perfecting Friction Drives

    One more thing on that low rpm limiter for Kepler. I was reading the data sheet on that LM2907 http://www.national.com/an/AN/AN-162.pdf On pages 8-9, there is a very simple example that looks like it might do it with the one tach chip with its variable latch out. I am not sure about the...

    RFC: Electronic Solution for Perfecting Friction Drives

    Mike: I just found a few things that might help on designing that rpm limiter. Both could use the speed sensor from a bike speedometer. One is a discrete circuit that could provide both a low and a high rpm cutoff. The other is an Arduino. There is a DC clone from adafruit.com for about $15...
