Brendan writes “I’m working on a little homegrown project centred around a creative use of a wireless webcam. Key to the project is the portability of the webcam. But there in lies the snag – power. I could go the iSight – laptop route which would work, and no need for power cables but ideally I’d love to have something that wasn’t as bulky. So anyway I was thinking would it be possible to wire up some hand crank power to a wireless webcam? Even if it only gave power for a half hour or so? Have you ever seen anything like this?” You could just wire up a 9v battery with a 5v voltage regulator (or whatever voltage the wireless web cam requires). Post your suggestions in the comments!
