Helmet Back Another great CVS camera hack HOW TOWhen I first saw the CVS disposable camera, I knew that it would be hacked soon. I also knew that as soon as it was, I would have to buy one, and I knew exactly what I wanted it for: Mountain biking. Here are directions for building a helmet mount for the CVS one-time-use camcorder. Includes photos and a 10 minute trail riding video. Link.
