Testing rocket motors is a dangerous business, as they have an annoying habit of releasing all of that energy a little quicker than you might like. [Jeff Hopkins] knows this, so he made his own wireless rocket motor analyzer that allows him to trigger, test and monitor rocket motors from a safe distance. This involves more than just pushing a button and watching them go whoosh: his platform measures the thrust of the prototype over 90 times a second and transmits this data to him remotely for logging and later analysis. His current prototype can measure engines with up to 400 lbs of thrust. That is a lot, so it is a good thing that his rig can also remotely arm, fire or safe the motors, all over a 70cm wireless radio link that keeps him safely out of the way. It is also built of cheap parts, so if a RUD (Rapid Unplanned Disassembly) does occur, it won’t cost him much to rebuild and start again.
This project is part of a bigger plan: [Jeff] is looking to build a high-power launch platform that can launch an electronics platform high above the earth. Could this be the beginning of the race to be the first hacker in space? We shall see…
