You would really be doing yourself a favor if you just bought one
instead. Or you could build one from a kit. Building the ultra cheap
"dumb" programmers is very likely to lead to much frustration unless you
happen to luck out with everything. You will have plenty of challenges
getting your PIC projects working without having to worry about your
programmer not working correctly. A good, reliable programmer uses an
on-board micro to do the actual flash programming so it doesn't depend
upon cable characteristics, pc port voltages etc... I use a PICALL
programmer as described at www.picallw.com It's fairly inexpensive,
includes a software license and works beautifully.

Instead of the 16F84, I suggest you look at the 16F628 as the 16F84 is
now obsolete. Since you are new to PICs maybe the 18Fxx2 type chips
might interest you more. You also ABSOLUTELY NEED to go to
www.piclist.com and sign up for the mailing list. ;-) Be sure to read
