Apologies on the late post, but here is the video from our test launch last month!
Successfully tested stratologger deployment capabilities at 10,000 ft and 50,000 ft within a vacuum chamber. Some deviation occurred during the 50k ft test, as the main chute deployment was delayed by more than 90 ft. This could be due to rate of depressurization of the chamber or an uncalibrated barometer on the altimeter. Further testing will be needed. Configuration settings and locating tone as advertised.
Electronic housing specifications have been narrowed down. Use of a 1″x4″ wooden plank for a support structure with threaded steel rods running lengthwise through the plank and surrounding bulkheads will be implemented. Bulkheads will consist of a carbon fiber bulkhead and aluminum face supplemented with wooden bulkheads that are o-ring sealed for the altimeter sensors. Currently waiting on ordered parts and diameter specifications of threaded rods/rocket body before further construction can take place.
Testing of carbon fiber housing around the recently purchased transmitter will take place ASAP. Further testing of the altimeter will be taking place next week along with some exploration into safety critical circuit arming techniques for use with current electronics bay design.
