So. Finished the bulk of my thesis, which frees time to work in this project again. Almost synchronized, the first iterations of the biohand's control boards arrived from the board house!

I rushed to test them. But yea. With all those small piched components, I didn't got around milling a version in my CNC before the design was sent off for manufacturing. So, it was kind of all-or-nothing. And as it's (almost) always the case, I soon discovered some mistakes. Namely, I swapped two VDD/VSS pairs from the STM32 processor. [...] It took me around 24h to find and solder a workaround and get a minimal setup (processor + regulator + caps) to work. LED blinking in the next pic:

Time to keep soldering (and eventually spotting other dumb mistakes, *sigh*).

BTW, more info on the project will soon be available on my personal page.

'til next time!
