Irish photographer David Hunt has found a great way of extending the capabilities of his camera - by attaching a single-board computer to it. Hunt has installed a Raspberry Pi, Linux-based credit-card-sized computer in an old battery grip. He's not got as far as programming the computer yet but has blogged about the possibilities (hard drive backup, control across the Internet or sophisticated interval shooting, for example). Powered by a standard Canon battery, the idea helps open-up the options for camera hacking, without having to get past the firmware encryption (as a resourceful user has done for the Sony SLT A55 recently).
