Having smoked my first AVR CPU, I now face the need to be able to reset the CPU fuses regardless of their current settings. After some searching around, I decided to purchase a kit rather than roll my own. I picked up a "HV Rescue Shield" from "MightyOhm Engineering".
A few simple minutes with the soldering iron and quite a few more minutes purusing the ATMega328 data sheet and I determined the values for the fuses that would get me back in business. A bit after the fact, I realized I could just read the current fuses on a working CPU chip and go with them, but it was educational nevertheless.
This little gem of an Arduino shield will handle the ATMega devices along with the ATiny2313 and 8 pin ATiny CPU chips. It also generates the +12v programming voltage on-board eliminating the need to have an external programming voltage supply.
So, back in business with my original CPU.
