David Hunt's Camera/Computer Grip

Irish photographer David Hunt recently blogged about this achievement. He took a Raspberry Pi computer, a linux based computer the size of a credit card, and built it into the battery grip of a 5D2 camera. He added twin USB connection, and even a HDMI port. What does this capability give the photographer? He reports the following options...

• 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.
