This was the first keyboard I bought keys and keycaps for; previously I only used hardware from keyboards thrown away by others.

Outer columns are 16mm apart instead of 19mm, keycaps have to be cut to fit.

On the left there is a speaker (taken from dead laptop) which optionally indicates when the hold function of a tap/hold key is activated (needs modified QMK firmware).

Two places for screwing into (pink parts) are not used in the picture: they can be used to attach a lithium battery in order to use it as a wireless bluetooth keyboard.

I spent some time enhancing the algorithm to convert the trackball’s outputs to mouse movements, but still it is no fun using it.
