BS2 and cameras

Posts: 1
I am working on a project for a college class, and I was wondering about interfacing a digital camera with the BS2.· What we want to accomplish is taking photographs from space and to be able to snap a photo every minute or so and save it onto an SD card that resides in the camera, which should last for around 3-5 hours.· A couple of resources I found uses RC controllers and more telemetry-type things, but I just want a basic system.· The questions I have are:
When the project is over, I will post some links about it on here.· It is really exciting and fun, as well as plenty of basic stamp interfacing in it too!· I appreciate any and all comments!
- Based on experience, what would be the best way of hacking into a camera to interface it into a circuit?
- What type of code should we use?· I was thinking PULSOUT or possibly something with a simple HIGH·PIN x·command with a Sleep inbetween shots.· I'm open to any suggestions.
- Is there a type of camera you would recommend?

Hope this will help.
Using a BS2 and a Pocket Watch B we set the time, set the alarm interval and based on that turn on the power relay, let the camera warm up, take a shot, let the camera write to compact flash, turn off the camera and wait to do it again. Simple, uh? Wish it was so ... we thought everything was working fine, except for some minor timing and power issues when the circuit started acting erratic. So may be posting my own help message soon ... ;-)
Anyhow, it should work and I can post my schematic and code if you like. Couple things to think about camera wise; Physical Size, Type of Remote used, Memory card/ FAT type ( we went for CFII, FAT 32), Can you control Sleep Mode, Image Resolution, and remember by the time you figure all that out and decide on a camera .... it may be obsolete (try finding a new A2 ...·Konica went out of the camera business 6 months after we designed around their camera!) They also stopped making the Pocket Watch B, so I have to learn the DS1302 after I get the original circuit working ... doesn't sound like it, but it is fun and the people here are a GREAT help. If I have been or can be of more let me know.
Cheers,
