This Rocket is designed to carry the payload of an egg and calculate it's own max height. Fits a C-class engine. Uses an ADXL 345 accelerometer ran by an arduino pro mini and a 3.7V RC car battery to measure it's own height. Accelerometer records steadily in Z axis only because it sits inside the gimbal. Sand paper on tip is to reduce the drag coefficient (see related photo). The egg added a little too much weight to the tip. Once it was removed it flew like a beauty.
Rocket was designed by Eric Smith (The Man, The Myth) and Dan Sluder (The Science Tutor)
The code provided is mostly stock code from arduino with minor changes. Once the data is harvested you can use the .m code to numerically integrate the data and get the height.
Set up is self explanitory. To make the parachute we followed this video:
Works much better without an egg. I recommend tossing "Gimbal Chamber to Egg Chamber Union" and flying it like that.
