This page has been gathering some dust now, but this will change in the next weeks.<\/p>\n

I’ve been working on a new project, the biohand.<\/strong> It’s a low-cost 3D-printed hand prosthesis, that aims at offering technical qualities similar to multi-thousand dollar devices. More details shall come in another post.<\/p>\n

For now, I’m just willing to share the nice fact that the first iteration of the biohand <\/strong>main control boards (a.k.a. the BIOHAND_BOARD_V1) arrived from the boardhouse.<\/p>\n

\"Biohand<\/a><\/p>\n

As soon as I finish soldering one of them and it survives the smoke test (or perhaps doesn’t), I’ll post further results and schematics.<\/p>\n

’til next time.<\/p>\n

EDIT:<\/strong><\/p>\n

It’s said that no man is without sin, and neither am I. In an act of brilliance, I’ve managed to swap two VDD\/VSS pairs from the STM32 while designing the board. While I didn’t burn a thing, I did cost me over 24h to figure out what was happening and to solder some workaround-wiring. In the end, the I got the ARM running a simple blink program (pic below). YEY!<\/p>\n

\"Minimal<\/a>
Minimal test of the board (Blinking LED, YEY!). Disregard the workaround-y bond wires.<\/figcaption><\/figure>\n

Now it’s time to keep on soldering the remaining components (hoping not to find other mistakes like that). I’ll upload corrected gerbers once everything works without bursting into flames.<\/p>\n
