I just completed a new project, Polaroids from Space. It’s my 5th and last High Altitude Balloon project. This time the flightcomputer were a lot of seed components, at the heart was the Seeeduino stalker, and some custom PCB’s from your Fusion PCB service. You can find all about the project here: polaroidsfromspace.com/
There’s a link on the website at ‘how’ that guides you to the code i had used for the launch, and the schematics, etc.
