Heh Guys,

I thought I would post this cool little RC Servo driver circuit using a standard 555. The only problem was that it was designed for a servo that has a pulse width of .5 to 2.5 mSeconds. I threw it up on a breadboard and it works just fine. You may have to change the values of R1 and R2 to change the pulses to fit your specific servo. Anyway the schematic follows. :)

Variations on 555-based servo drives have been around for a long time. I have been using one since I got back into the hobby 25 years ago. They usually work well with analog servos, but with some digital servos, they can cause chatter and do not not work.
