Review on Geekstory Microcontroller Programmer Downloader Adapter by Bob Fasho

AtMega 644 programmed upon receipt, no problem. Postponed for a few months and then tried to flash AtMega 168P and couldn't. AVRDUDE showed that this is a firmware problem on the USBASP. I tried to update the firmware using Uno R3 but could not connect despite known and tested good connections. Something on the circuit board didn't work. It worked once. Now I'm trying a different device.
