Here's a very interesting Project. With a Raspberry Pi setup to interface with a DSLR Camera...
Don
I've had the idea of embedding a computer DSLR camera for a couple of years now, but for whatever reason I never got around to implementing it, mostly due to the cost of small single board computers. Until now, that is. With the release of the Raspberry Pi, embedded computing has all of a sudden become much more affordable. At €35 for the computer, it's far cheaper than any of it's rivals.
So what I've done is take an old (broken) battery grip that I had lying around (for my Canon 5D Mark II), and made a few modifications to it so I could fit the Raspberry Pi SBC (Single Board Computer) into it.
The result is what I call "Camera Pi".
I left a few holes in the case so that I could get at the USB and network ports, and video port. it's a fully functioning computer with a Linux Operating System (Raspbian), has 2 USB, network, video, HDMI and GPIO.
Possibilities include:
There's plenty of work to be done on the software side of things but the prototype is working. I can pull images from the camera and transmit them via either Wifi or ethernet. There's a significant problem with the current USB drivers on the Raspbian linux disribution, though. After a few requests to the camera, the gphoto app responds with "Unknown Error", and the only solution seems to be to unplug the usb cable and re-insert it. Not a workable solution, so I'll have to look into that. Works fine on my other linux box, but a full-sized PC won't fit into the battery grip!
–Note– I found a wee 'C' code snippet that will reset a USB port, and that seems to do the trick if I call it between each gphoto2 call. Not ideal, but it gets me away from constantly unplugging the cable….

Camera Pi – DSLR Camera with Embedded Computer

Possibilities include:
- Wireless tethered shooting – attach a Wifi dongle to the USB port, so I can transmit pictures to a PC or tablet PC as I'm shooting.
- Attach a USB memory key or hard drive so I can back up the images on the camera.
- Remote control the camera using a PC, tablet PC or smartphone (from anywhere in the world).
- Intervalometer – take a picture every few seconds for those high-speed sunset sequences, including exposure adjustment as you go.
- On-the-fly image conversion for faster previews on remote display device (iPad, etc).
- Add a small LCD display to give status, allow user input via buttons, etc.
- Trigger camera via shutter release port, also allows waking up of sleeping camera, which cant be done via USB.
