So I came up with an idea of Cannon DSLR remote control. They are relatively cheap to buy on ebay, or other local online auction sites like allegro.pl here in Poland. But I wanted to build something by my self. As a complete amateur I wanted to make something small, and simple, thus DIY IR remote control for my camera was born. The protocol was reverse engineered by some smart people over the internet, so all I needed to do was to design the PCB, solder the stuff together, write a program and flash it.
