AVR HV RESCUE shield

While playing with an ATmega168, [Jeff] programmed the RSTDISBL fuse bit. This quite much makes the chip useless in a lot of cases. [Jeff] didn’t want to provide up on it though, so he built a system to program it utilizing the seldom utilized high voltage parallel programming mode. He utilized an Arduino, a few lines of code as well as a few spare parts to make it. After sharing the concept with some fellow programmers, he made a decision to make an Arduino shield particularly for this purpose. You can utilize this to reset nearly any type of fuse to rescue a chip. If you are a die difficult AVR person as well as never started utilizing Arduino instead, the STK500 really has this built in.
