Miniscule DIY DSLR Intervalometer

Time-lapse enthusiast and electronics wiz Achim Sack came up with this super-small hardware-based intervalometer. Only a little larger than the size of a standard 2.5mm stereo plug, the device doesn’t require any special setup or configuration — all you do is plug it into your Canon/Nikon/Pentax DSLR and then take two photographs between 0.4 seconds and 18 minutes apart. The device will continue to shoot photos at that interval until the memory card is full or the battery dies. Sadly, it’s not for sale, but if you’re handy with electronics you can find the schematics and code for free on Sack’s website.
