PIC & Electronic Development on a Shoestring

The programmer links on that site are a bit mis-leading, as the PICS used here (at least for Renard and Ren-C) require a programming voltage of around 13V, which those programmers do not provide. Those programmers may be good for some PICs, but not the ones used here (although I don't know if the PICs used by FireGod or RJ need the high voltage).

13V? I have been programming the 16F688 chip with the PicKit2 at 5v off of the USB port power only. What chip is requiring the 13V?

The PicKit2 has circuitry to create +13V from +5V (a small switching supply). The PIC itself requires the higher voltage on the VPP pin (pin 4) in order to program it (just for programming, not for normal use).
