Haven't tried regular-sized choc switches before, but they should work. One thing to consider would be that with the heigher switches, the scroll wheel might be harder to reach with the thumb because it might be physically hidden behind enter/space. Should not be a problem it you are used to use the index for them though.
there is another one that does something similar but that is not open source as far as I can tell: https://github.com/sprengboard/choccy
My first design! Github link to the repo with pcbs and 3d printed components: https://github.com/dnlbauer/corax56-keyboard
I just kept the default value (I think its 0.2mm) between traces. I could probably double it at some points where multiple traces are bundled though. Thanks for the hint!
thanks for the imput. Do you mean I should just place some random vias to connect both sides of the ground plane? To be honest, I dont understand exactly what this ground plane is used for since none of the traces actually connect to it. Is it merely for shielding against signal noise?
Hey, unfortunately erdogen, which I used to generate the starting point for the pcb does not generate a schematic file. It only generates the PCB and ratsnest for the footprints. So I dont have one. I think I could create one though. Mind telling me what this is used for and why one should have one?
fixed the domain. thanks for pointing that out!
If you are interested in the design process, I can highly recommend the tutorial series by FlatFootFox here. It was a great resource for me to get started. https://flatfootfox.com/ergogen-introduction/
Hey everyone!
I jumped into the ergomech rabbit hole sometime last year and after using a sofle as my daily driver since then, I now decided it's time to build my own "thing". After going through endless revisions to figure out what I actually want, and trying to learn how to trace PCBs, this is what I have come up with: A choc-spaced 56 keys wireless build with a scrollwheel and some staggering.
It's a reversible PCB. To make this work with single pin hole for both sides, I used jumpers for pins that can not be set in software (VCC, GND, RST). For rows/columns, I plan to do a different mapping in software to not have a jumper for every single pin.
All files including the kicad_pcb and ergogen config are available and open source at github: https://github.com/dnlbauer/splitkeyboard .
However, this is the first thing I ever designed. Therefore, I was hoping if you guys could have a look at the PCB before I get it etched and point out if there are any obvious errors?
Of course, I am also happy about any feedback in general. :)
No, you solder it in the same way for both sides.
The "flipping" is handled mostly internally. For The right hand side, the firmware just maps the rows and columns differently than for the left hand side. For pins where this is not possible (Vcc, Gnd,..), there are jumpers on the other side that need to be soldered.
