From PCB to Space: Assembly, Testing, and Coding for Low Earth Orbit

Making the module real, and the troubles that ensue! PCBA's the easy part, getting to shipment though...uuf! All the goods get gotten in my mailing list at https://news.psychogenic.com/spasics -- tips, updates and finds all to your inbox. Continuing with the pocketqube satellite experiment module design we did in https://www.youtube.com/watch?v=I-tqtEzP2bo now it's time to do PCBA, bring-up the circuit, test, program, and debug debug debug as the deadline to launch looms. There are a few surprises in store in the process that need to be overcome if we hope to get micropython and a custom ASIC running in low Earth orbit. *** Hunity *** Some details about Hunity, the BME satellite on which we're getting a ride, from Alba Orbital (the launch broker arranging to get us all to LEO): https://www.albaorbital.com/bme-hunity If you want a deeper dive into the platform, Matt and I got to chat with Tibor from BME who's giving us the ride to space and it covers a lot of the specifics of the satellite, pocketqubes in general, the other experiments on board and more: https://www.youtube.com/watch?v=SRuBDMZZiI0 *** YOUR own code, running in SPACE *** The guide and sample Python code for creating experiments to run on the modules is all at: https://github.com/psychogenic/spasic_experiment_testing *** Experiment Module *** The spASICs repository is at https://github.com/psychogenic/spasics and that's where you can find the hardware design files, the requirements document (PRD) and stuff like that, including the fully documented I2C protocol/API https://github.com/psychogenic/spasics/blob/main/doc/ExperimentModuleAPI.md *** Customized uPython *** My fork of the micropython rp2 port, with the i2c module: https://github.com/psychogenic/micropython/tree/rp2-i2cslave/ports/rp2/modules
