The LeedsHackspace has entered a challenge against Pumping Station 1 thanks to Element14.
We have 4 weeks (less than actually due to various delays, etc.) to get a project going and win a vote on Facebook to get the prize. This is ideally using the device Beaglebone Black which is, effectively, a high spec Raspberry Pi with GPIO connections on it (so like a Raspberry Pi with a PiFace or Arduino integrated).
