My son is working on a 9th grade science project. He is experimentally determining the optimum amount of water to launch a water bottle rocket at a given pressure. I've used those Estes model rocket altitude finders in the past, but they are not very accurate. Can any of you tech savvy folks out there help with ideas for inexpensive electronic telemetry? I've seem some stuff online, but I trust you guys more than some random posting. We are perfectly happy with a unit that would download the data after flight as opposed to transmitting to a ground receiver.
I have to admit that I steered him toward this project for selfish reasons. I coach the Science Olympiad team at the middle school where I teach. One event is producing a water bottle rocket that remains aloft longest without any recovery system. I figure I'll put the kid to work to help out my team!
