auto-range capacitance meter
This project like others capacitance meter that use charging time measurement technique (ฯ=RC). Circuit is really simple. There are three buttons used. Two of them are used to calibrate capacitance meter in order to remove stray capacitance. Third button is used to save calibration data to EEPROM memory. You can download assembly source code compile and burn to PIC16F873A microcontroller. I guess this is a nice tool that fits in to collection.
