RC Servo Controller with Preset

Below you find the schematics of the servo-controller I use. It is based on the PIC 16F84A from Microchip. To obtain a good resolution, I use a version of 20 MHz. It's interfacing to the serial port with a rate of 38400 baud. The PIC is controlling 12 servos in parallel with a resolution of 240 steps over 90 degrees rotation.

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
