A few years ago I attempted to put a camera in a small rocket. I had always had the idea in the back of my head, but I never knew how to do it. As soon as I saw this Make Magazine article I knew I had to try.
I mostly followed the advice in the Make article. The major problem I encountered was what camera to use. I didn’t want to risk damaging anything expensive, so I opted to use a $30 CVS “one-time-use” video camera. The Camera Hacks forum has useful information to get around CVS’s security and make the camera reusable.
With the help of jbgizmo.com I built a cheap lightweight altimeter that uses a pressure transducer to calculate altitude.
I launched the rocket once with the camera and once without. Both launches had the altimeter. The launch with the camera used a D12-5 engine and reached an altitude of 420 feet. The launch without the camera used a E9-4 engine and reached an altitude of 835 feet.
