I'm impressed that some of you are able to log into the comment system, considering that user/pass labels are not working. The force is strong with you.
I got a basic PWM DC motor fan speed control working with the 555 timer. It's pretty simple, including a homemade capacitor. I can get the fan going pretty slow, but can't quite get the duty cycle low enough to get slow crawling RPMs.
