anOn, thanks for the reply. I've experimented with air release bulbs, with actuators mounted in the wood of the box. This works fine for doing one function, like snapping the picture. But more complex functions like telling the camera to print 5 photos instead of one requires switching to the review mode (which I've accomplished via a physical bar that extends outside of the box camera), then pressing the function button one time, the up button three times, the right button 4 times, the down button 3 times, and then the function button one last time to print the photo 5 times. It's this 'printing multiple copies' issue that's driving me nut's.
Can CHDK be used for scripts in the review mode? Thats actually where I need it most.
I can't be reaching inside the old Scoville constantly. I was wondering if CHDK might be the answer. As i was reading these posts, I saw other very intriguing ideas as well, such as USB shutter release. Thats when I thought about some sort of devise, tethered to the camera via usb, at 3-5 volts, with several buttons that activate several different scripts. This remotely tethered devise could be an airbulb split in half with a tiny keypad inside.
BTW, You mentioned an airbulb operated rotary switch. Whats a rotary switch? Sorry to be so dense. You can probably tell I'm not all that technical.
