I'm attempting a 'diy sensecam'
I bought a cheap, **broken link removed** that I can wear around my neck, and I want to be able to have it take a picture every 30-60 seconds throughout the day.
Since it only uses one button to turn the unit on and take the picture, I figured the easiest way is to just attach a relay or transistor to the power button and have it send a trigger signal through this cycle:
What would be the best plan of attack here? A 555-timer? A PIC/arduino? Which would save the most energy?

Since it only uses one button to turn the unit on and take the picture, I figured the easiest way is to just attach a relay or transistor to the power button and have it send a trigger signal through this cycle:
- On.. (wait 2 seconds)
- Take picture.. (wait 2 seconds)
- Off (hold for 2 seconds then Wait 30-60 seconds)
- Repeat
