An interesting article to read, would love to see a larger samples size at some point. I am also going to continue drinking my mid-day espresso, morning coffee, and afternoon pick me up caffeine drink...

This was great, I loved all the parts it was super thorough :) You have to love serial ports on embedded devices, especially non password protected root access

You did an amazing job, soldering wire to BGA pads must have been fun :)

What was the probe tool you were trying to use?

Looks like a “spider probe,” example of one here:

Thank you :)

This was a joy to read, your easyEDA design looked great too! I didn't know they had 3D capabilities.

I enjoyed reading through your debugging process and as someone who has been trying to debug a custom board for a few weeks now I feel your pain. I still cannot say that my issue is hardware, firmware, or software -_-

I do have some UART devices that really seem to like when I just disconnect and reconnect the GND wire when they start to act up.

Your phone will do this automatically and will not show you you have been connected to a hotspot on the main screen, it will still show you as connected to cellular, this is most likely a carrier hotspot.

I was really hoping to see a picture of it in dim light with the valves glowing. Also I was not expecting to see such an adorable light house for ducks in the post. All around a great read :)

I have stopped using MicroUSB in my designs because without fail at some point I rip the thing off the board -_-

normally only occurs while aggressively debugging

thank you for summarizing the results, I feel much better about my job security. Now if AI could make a competent auto router for fine pitch BGA components that would be really nice :)

I will always love raspberry pi's, they are well supported and great for quick and cheap prototyping. I have used them to teach children how to code (They really enjoyed working with sensehat), research at university, and at work for rapidly prototyping. The size is also easy to work with.

There are better SBC's out there, but raspberry pi is familiar.

I really hope the recent IPO doesn't change too much...
