[in progress] Altimeters

Commercial off-shelf altimeters are often required and just nice to have for redundancy. We use the 2 perfectflite stratologger in the avionics bay for main and drogue parachute deployment.

Programming

For the most part, the altimeters do not need to be programmed once bought. It can be reprogrammed for different modes including ignoring the first X seconds of flight. Refer to the manual linked at the bottom of this page but the reprogramming wires are purchased and housed in the Etcheverry locker.

Wiring

Positive and negative does not matter for main and drogue as both sides go to an E-match. Same with switch, both sides are the same. However, make sure that the positive and negative sides of the battery is connected properly and listen to beeps for accuracy.
