Sometimes you need to squeeze a little bit more from your camera than human power can do. Then you let the job for some automatics. So there it is – an intelvalometer to determine time lapse for cameras like Canon, Nicon DSLR, and Pentax.
The project is based on very small PIC10F222 microcontroller in 6 pin SOT23-6 package. It runs on very low power that can be taken directly from cameras jack port. Interface more than easy – you simply have to teach dongle by pressing camera trigger twice in desired time and then the third (and further triggers) are done automatically.
