As every DIY project, the goal was to be quick and +simple (spoiler: it was neither). + +Half of the parts have been soldered with a soldering iron (TS80P), the other +half with hot air station. Clearly, with my [un]existing soldering skills, the +hot air is a huge win. But I think I would have simply spent more time by only +using the iron. Even the small sod-323 diodes without the `_handsoldering` pads +(mistake) were not a real problem (tricky, but even I could do it). + + + +The trickiest +part is the USB connector if you don't have a hot air station: the plastic +casing melts with the solder. + + + +* The LEDs are mostly optional, and the 6 used for the backlight are nearly + useless. I did not really study how to insert LEDs for a nice backlight and the + result is not really satisfactory. +* I'll hopefully find time to use plexiglass plate to put below the PCB and + above the visible part. I've added holes for this but never really planed + anything really. If you really want something nice here, you may check this + before. + + +## Layout + +As a typematrix user, I really like the middle column with `backspace/enter/del` +so naturaly I've tried to do something similar.
