JDM2 PIC programmer

The previous PIC programmer that I posted only programs a PIC16F84. You may want to build a PIC programmer that will program a higher variety of PIC chips.

After seeing all the cool projects people were doing with Microchip PICs, I HAD to have a PIC programmer. About a year ago I made my first PIC programmer based on the uJDM design [http://www.jdm.homepage.dk/newpic3.htm ]. This programmer uses 6 common components. Though the link says ’16F84(a)’ only, I used it for the more modern (and cheaper) 16F628(a) processors without problems. This programmer has served me extremely well, but it is limited to (less than) 18 pin PICs with a programming Vpp of 13 volts.

This ‘instructable’ covers my new design that programs 8/14/18/28/40 pin PICs. The circuit is based on the JDM2 programmer [http://jdm.homepage.dk/newpic.htm ], with two enhancements: clock and data line filtering & selectable programming voltage….
