DIY Canon 550D Wired Remote Control With Built-in Shooting Intervals

By | February 20, 2011

Over the weekend I have decided to make one of my own remote control for my new toy Canon 550D.

Right now it has 2 interval settings, 10 sec and 30 sec

The 2.5mm circuit is normally open, to focus or shoot, you close the circuit, no external power is required.

Things to improve:

  • Instead of using a rotary wire switch, should use something else that changes voltage on a wire, therefore I can adjust the interval by reading the voltage.
  • Simpler and smaller battery pack
  • A button to manual control shutter
  • More compact design
