Tethered SD card
I would like to tether a cheap digital camera. The problem is I don't know which one - I'm watching on ebay for a madly cheap camera (I've seen loads go where they're fine except for a stuck zoom - like 6Mp cameras for about £3 - when every time I've looked at a stuck zoom a bit of twisting and brute force will get it back in to the body - and the project I want it for doesn't need to zoom!). Problem with doing this is that by the time I've found a cheap camera with 2 minutes to go, it tends to take a lot longer to that to figure out whether you can tether it. And even then you're normally limited to the provided software, I'd like to be able to write my own.
So - can anyone think of a way to take an old SD card and somehow - I don't know - solder wires to the insides of the contacts maybe - and then somehow get those wires into another old SD card and plug it into the card-reader attached to a PC so that you can read the images without unplugging the "card" from the camera?
