i made this keyboard because i saw the KNOB keyboard on reels, and thought it was probably the nicest looking keyboard ive seen, but unfortunately its like 400usd, way too expensive
i wanted to learn how to make a full keyboard after hackpad anyways, so i designed this. i also want a bluetooth keyboard because my current keyboard has a cable thats very annoying, and i wanted to replace it.
