This is an IR remote control for Nikon cameras. The circuit project is very simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery. You can also connect the IR diode directly to the ATtiny13V, but that will limit the LED current and therefore the range. The project is compatible with the Nikon ML-L3 remote control. Supported cameras include: D40, D40X, D50, D60, D70, D70s, D80, and Coolpix 8400 8800. This project created by Dick Streefland
