I've no doubt Al's and Phillipe's solutions work well. But you can
in fact "build" a PIC programmer with your Stamp alone if you use a
PIC in the low-voltage programming series such as the PIC16F877. A
simple Stamp program is all that's needed to impement the programming
protocol and twiddle the PIC pins to load the program. With a little
more hardware you could switch the higher programming voltages needed
by conventional PICs.
Loading a useful PIC program with this approach is a little more
complicated. Nearly every PIC programmer ever made uses a
disk-resident .hex file (the output from your assembler/compiler) as
input for the PIC programming per se. Until somebody figures out
how to get a Stamp to read a disk file directly, you have to
download the .hex file from the PC to the PIC via the Stamp.
This isn't the most user-friendly or elegant approach, but lets you
try your hand at PIC programming using stuff you probably already
have if you're a member of this group: a Stamp and a PC.

Depends on which model you want to use, and if you have a PC. I use a (very
!) simple programmer hooked to a serial port (no need to supply external
voltage !) to program the 16F84. I think this model is useful for simple
applications. It works perfectly.
Let me know if you need more info.
Best regards,
Phil.

can find the schematics and software in my Stamp Book (the parts are easy
enough to find). You either need a Vpp supply or a good enough serial port
to supply 12V.
