Arduino-based Rocket flight recorder

Jon Oxer has been very busy as a recent post on his blog attests. The fruit of his work? An Arduino-based rocket flight recorder no less!

The image and quote are from Jon's post:

The bottom board is an Arduino Pro Mini 5V/16MHz from Sparkfun. Sitting on top of it is a 433MHz transmitter module from Jaycar, and the circular PCB to the right is a Lilypad 3-axis accelerometer breakout board. To give some sense of scale the entire assembly is about the same dimensions as a 9V battery, so it's very small and light. You're looking at it lying on its "back": the plan is that it will mount vertically in the nosecone of the class-C rocket that Marco provided so that we can log accelerometer data from a launch. When fitted into the rocket the round accelerometer board sits flat in the bottom of the nosecone so the Z-axis reading will align perfectly with the direction of flight.

According to Twitter posts Jon's also taken delivery of a 5Hz GPS module, and after experiencing some difficulties with the Locosys GPS module, it seems to be behaving.

With the two joined together hopes are to get the system transmitting x/y/z force plus lat/lon/altitude every 200ms. If everything works out well we may even get a nice flight track from the location points. Sweet!
