split ergo keyboard

· electronics, misc

after about a week after building a keyboard, i really wanted to build another keyboard. it was really easy the first time and felt more like assembling something than actually building one. i have been learning to type with colemak-dh, so while my mind is learning i decided to learn something a bit further than usual

it seems that split ergo keyboards are quite good for your hands long-term, as well as the colemak family of layouts. additionally, most split ergo keyboards that I see are very much self-built and quite customizeable.

the keyboard i decided to go with was the open source 38-key choc v1 totem by geist (see details here. I have never used kicad before as i typically just go with easyeda, so i loaded up their files to modify and get familiar with how it works. I added some interesting graphics to the top to rep my favorite ai mass surveilance company.

pcb order
seems to load up nice, except the black part in the middle was worrying as that part is supposed to be a hole and not have anything there
when the pcb arrived, i soldered everything up. I ended up going with the wired variant because i figured it would be easier to service that way. i also opted to go with the tentable option, i heard some people praise tentable feet. before fully assembling, i tested using tweezers to jump the hotswap socket pin holes.
testing
testing the keyboard with no switches or anything
everything worked, so i 3d printed a case for it and assembled everything. I used just regular pla for it with the textured build plate
working
working
everything operational, with tented feet up

i went with kailh ambients bokeh for the switches, and they feel great. the keycaps, however, do not feel great. i printed flat keycaps, also textured, and they feel weird and scratchy. my fingers feel like they hate touching them. later i decided to sla print some keycaps. somehow i managed to screw up all of the prints i tried, maybe due to old or poorly mixed resin. i do hate sla printing so i went ahead and just left it as is with a couple of the good keycaps. the sla printed ones did feel significantly better though.

double failure

overall though, im pretty happy with it. its great to use for while i learn to type on a setup like this for sure
