I have the USBtinyISP kit from adafruit.com and I blew the 74AHC125 IC when I was working late at night and accidentally connected VCC (or perhaps RESET) with 12V VIN. Oops. I checked my cabinet for a replacement part but, alas, I didn’t have one. I figured I was out of commission with the USBtinyISP until realized what the 74AHC125 part was being used for – a level shifter. Since I am currently working in 5V only, I didn’t really need the level shifting feature so I decided to remove until I could order a
Since I had the programmer apart, I decided to upgrade the firmware from 1.04 to 1.06 . I also didn’t have a 12MHz crystal/resonator on hand so I improvised again. Using the resonator on the USBtinyISP I was able to update the firmware using my Arduino UNO as an avrisp. In the image you can see that I added jumper wire from pins 4, 5, and 10 of the ATtiny 2313 in the breadboard to the socket’s pins 4, 5, and 10 (respectively). Using this setup, I was able to upgrade the firmware and now I can use the USBtin
