That's more space for keys
The HP 97 is 23cm wide which is a comfortable size. At 30cm, a standard keyboard would fit.

I'd say software design isn't difficult I doubt I'd be able to design a PCB well. I'm sure anything I did design would fail emissions testing badly if it did somehow work.


These would go well with a wooden case: https://mechanicalkeyboards.com/shop/ind...tail&p=295 A touch of pyrography for the labels.
