My PIC Programmer
An easy-to-build PIC programmer, based in the JDM. Uses the serial port. (10/24/2004)
This is the simple and easy-to-build PIC programmer that I use for many Microchip(r) microcontrollers. Only a few parts, JDM Compatible.
I use IC-PROG with this programmer. I programmed sucessfully the PICs 16F82, 16F628, 12F629, 12F675, 12C50X, also 16F87X series.

Before building this programmer, be sure that your serial port (RS232) have at least 11 Volts. At least 11 volts is needed to program the Series "C" (12C50X, 16C84, etc). With 9.5 volts you will be able to program only a few microcontrollers.
UPDATE: Doesn't work? Maybe the voltage at the port is not good enough. Put a 10mF capacitor between the VDD and GND (Indicated by the blue arrows in the schematic). April 23, 2006
