Hey, I’m wondering if it’s possible to use the PCB of one half of a split keyboard, as a one-handed keyboard?
Since the minimum order quantity at PCB fab shops is usually 5, we’d be able to make 2.5 split keyboards (assuming reversible PCB) if nothing goes wrong. I feel kind of bad for that 0.5 of a split keyboard, and I’m wondering if it’s possible to simply rewrite/tweak the firmware, so that it can be used as a one-handed keyboard (something like the Eternal Keypad)?
I tried googling, and it appears that someone has asked this before on reddit, but I don’t want to give reddit pageviews :|
Thank you for your time :)
AFAIK you can just build/flash per normal and it’ll work if it’s the left half. There might be a little extra work to get the right hand side working without the left (if you wanted just a right hand)
Wow, that’s much easier than I expected! :D Fortunately I’ll probably use the left-hand side, it’d be very convenient for playing computer games. But for knowledge’s sake, how would one go about making it work for a right-hand side? (I’m guessing it’s got to do with setting the ‘master’ half, but I’m not sure.)
For most it’s just a matter of flashing some different eeprom on first flash and that’s it. Most qmk splits define the EE_HANDS feature that allows the handedness to be written to the eeprom. So should be as simple as
qmk flash -bl avrdude-split-right -kb <keyboard> -km <keymap>or if its a DFU device then swapavrdudefordfu
