Jonny Hyman, whom I earlier posted about, has now consolidated his rocket efforts under the name Exoplanet Company. Jonny has started by open sourcing his GUI he has built to test his rocket engines and this can now be found on GitHub for you to download and set up for yourself!
In the 2nd video below Jonny explains how the GUI works and how it is integrated into his ground test system for a hybrid rocket motor.
Make sure to follow Jonny on Twitter as he recently live-streamed an engine test, unfortunately, a bad ignition did not lead to a sustained burn. Never the less watch this space!
