tinyISP stopped working
I built it a week ago, and set the fuses and dumped the Decimilia bootloader to a couple ATmega168 chips so far to make sure it was working. I plugged it in today to do it on a new one and I get the dreaded "avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51" on everything I attach it to. The pin 13 led flashes once along with the red one on the tiny when I run "avrdude -c usbtiny -p m168". Any suggestions?

I've tried it both plugged into an Arduino and a breadboard. I was having success with both last week.
I tried powering things both ways. With the JP3 jumper off, the Arduino was powered off a 9 volt battery, and I was powering the breadboard off a bench supply at 5 volts. With the jumper on, no external power was supplied to either board.

I tried it again this morning after rebuilding my computer (when power supplies smoke and pop, no good can come from it), and the programmer is working now. I'm fairly certain I know where the blame lies for the problem at this point.
It looks like I got a couple bricked ATMega168s out of the deal too. Good thing they're relatively cheap.
