I have an old digital camera that I want to do some time lapse photography with. The goal is to take a picture every minute or so. I've taken my camera apart, and found two contact points that when closed make the camera take a picture. Pretty much the same as what these three tutorials explain:

http://www.instructables.com/id/Quick-and-Easy-Electronic-Time-Lapse/
The thing is though, I'm green when it comes to electronics and each one of these tutorials is using a different method to make their timing circuit, and they're all really vague. One uses a microcontroller, another uses the arduino, and the other uses some weird MK111 timing kit.
I just want to do something as simply as possible. I thought a 555 timer would be a good starting point, but all the projects and tutorials I look at dont seem to be doing what I need. I figured I could just adapt some general blinking LED breadboard project to this, and replace the LED with my two contact points, but the circuit is opened and closed at equal intervals.
Is it possible to make a 555 timer keep a circuit open for a minute, closed for half a second and repeat until the battery dies?
