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
