Just want to make the point that I can take _no_ credit
for the pwmeter.zip design. The guy who did it is Georg Lerm.
I'm just a mere PS to GIF converter boy (That's where you
start when you're a junior at CSH HQ - hopefully I'll get
a promotion soon).

I have designs for PIC programmer that can be whipped on
a bread board in less than an hour and will program almost
any PIC. Only requires two voltage regs, an open collector 
hex inverter and a coupla transistors/resistors/capacitors.
