I have no affiliation with these guys. Carbon Origins is planning to sell a rocket data logger for a $150 donation on Kickstarter. The logger includes sensors for temperature, pressure, humidity, light intensity, 3-axis acceleration, 3-axis gyro, 3-axis magnetometer, and a GPS. The data are logged to a uSD card. Connectivity is via Bluetooth, WiFi, or an onboard small display. If the product works as described it is pretty interesting. We all know rocket electronics can have unusual failure modes though. http://carbonorigins.com/apollo http://makezine.com/2014/09/21/rocket-scientists-are-arduino-at-heart -->MCS .
