Re: [PSUBS-MAILIST] article on the OSS

Actually, a PWM motor controller is pretty dang simple. You could almost
call it a no brainer. It does get more difficult as the current increases,
because of the isolation, but it isn't rocket science. One of my first
electronics projects was to make a PWM motor controller with a 555 timer.
Reference TTL Cookbook. The MSP430 has a PWM built in, all you need to
do is supply isolation and a couple FETs or SCRs. So, Dale wasn't that
far off. This is also why I said that there were no if-and-or-buts in
the motor controller method. PWM is easier, cheaper, more reliable, and
vastly more efficient then manual switching or resistive methods.
