IR Nikon Remote via USB
This is an attiny85 based project that allows me to take pictures on a Nikon camera through sending IR signals to trigger the shot. I used code from Here and Here to create this project over the weekend. Once finished prototyping I designed a little laser cut case for it. This project cost just a couple of dollars with the only real cost being the uC for which I paid about $1.50. My code is downloadable Here.
