PiggyFuse HVSP AVR fuse programmer

PiggyFuse2-600

Nerd Ralph published a new build:

Although I’ve been working with AVR MCUs for a number of years now, I had never made a high voltage programmer.  I’ve seen some HVSP fuse resetter projects I liked, but I don’t have a tiny2313.  I think I was also hesitant to hook up 12V to an AVR, since I had fried my first ATMega328 Pro Mini by accidentally connecting a 12V source to VCC.  However, if you want to be an expert AVR hacker, you’ll have to tackle high-voltage programming.  Harking back to my Piggy-Prog project, I realized I could do something similar for a fuse resetter, which would simplify the wiring and reduce the parts count.
