OpenInterval project posted at last

OpenInterval is an older project of mine to create a universal IR interval timer that can support any camera capable of accepting remote control input. I left it at the point where it supports my Nikon D70s, and that’s where it sat since 2007. The only inkling the web got of this project was it’s git repository, it’s about time the project saw the light of day. So, here’s to OpenInterval, and all the photos it will take! Cheers!

    Great project, I have been looking into building something like this and I was wondering if you had a schematic to go along with it. I am having some trouble deciphering the assembly code.

    The circuit is very simple. Connect a NO button to pin 6 and ground. Connect the IR LED to pin 5 and a normal LED to pin 2. The ATtiny13 will sink current from both LEDs, be sure to use appropriately sized resistors to limit the current.
    Be sure to let me know how your project goes!
