My latest project involves wireless transmission of data from an Arduino-compatible micro-controller called a JeeNode. My first application was transmitting acceleration and pressure data from a water-powered rocket so that I can determine altitude and speed.
The first launch, done at the minimal pressure of 40 psi went 150 feet and reached 140 mph! The second launch also transmitted flawlessly, right up until it hit the roof of the house, knocking the batteries out.
simulator on line. This is very similar to what I do at work, analyze simulation data! I'm amazed at the initial acceleration and speed. There is a lot of energy being transferred rather quickly (~0.3 seconds)! Now I can optimize the flight parameters (up the pressure), and see what altitudes we can reach. Well, maybe I should work on the landings first.
