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, […]

High voltage serial programming for AVR chips with the Bus Pirate
Leonerd writes: I am happy to report a full success using the Bus Pirate to program HVSP on the 8- and 14-pin ATtiny chips. This requires a small additional bit of hardware, to use the AUX pin to control a +12V supply to the ‘tiny RESET line, and the 4 GPIO pins attached to the […]
