Hi
I am thinking of designing an electronic speed controller for a remote control car using a PIC.  I have a number of ideas at the moment, but my favourite is to use the microchip application notes for creating a pwm (an654) with the 16f84, then convert the incoming pulse into a pwm stream.

I have read that the circuit cellar published an article a few years back on doing the very same thing, but I have been unable to get onto their web site.  I have been trying www.circuitcellar.com   is this the correct site ? 

Any hints at all, from choice of mosfets, noise considerations, to programming tips would be greatly appreciated.

Regards,

Pete
