Well, if you absolutely needed to use that specific rpi camera module (if I understood your other comment correctly) and you didn't have time to reverse engineer it, then rpi was probably the best option, sure. It just feels weird to assume that, or that every single module needed to be connected by ethernet. Rpi and low power in the same sentence also feels weird. I'd have tried to build little devices out of STM32. But again, I barely know anything about your project.
Ethernet was handy for moving the images off the Pis once they were captured.
The RP2 was indeed low powered compared to the Intel/AMD powered systems we were otherwise familiar with.
Outside of the bubble of people with EE skills, however big the bubble is, stopping to learn expert-level mcu programming from scratch is rarely the way things work in a software startup. Despite the obvious focus of this thread, the hardware we assembled and configured was all in support of our software.
I assume that the rather hostile reaction you've received in this thread stems from the combination of your insistence that you tried everything to "bend the law of physics", but dismissal of any suggestion of simpler methods because you're a software person and couldn't have possibly thought/known of everything and we should just all assume that you found the optimal solution. Said differently, it's a strange combination of "we were a team of geniuses so trust me our solution was the best one" and "we were all software people so stop suggesting hardware solutions, it was too complicated for us to learn".
I didn't perceive a hostile reaction, beyond one dude who declared that something hard would be easy.
On the contrary, I've had a number of solid back-and-forths with folks about GPS, GPIO and homebrew RTC daughterboards that we could likely find success with today - almost a decade after we built what we built.
I'm honestly not sure what else you expect from me. Should I apologize for our relative ignorance at the time? Are you upset that I'm proud we managed to succeed despite doing things differently than others might have?
