Karman Avionics Boards
Interest and problem
-
Needed a telemetry system to recover data from rockets while they're flying
-
Interested into working with micro controllers and electronics
-
Need small, efficient, expandable system to increase reliability of our rockets
-
Had to teach myself everything - no formal electronics training at all
Design
-
Worked off of the Teensy architecture - more robust version of Arduino
-
Used breakout boards for the sensors so it's easy for other people to assemble boards without worrying about surface mount components
-
Began design iterations with Kicad for PCB fabrication
Results
-
Two rounds of PCB prints - improved design and fixed bugs
-
Hand soldered system for flight
-
System tested and flown on a custom rocket, worked first flight
Future
Currently designing next generation system to be much more capable, smaller, and more cost effective.
