I really like Lenovo’s TrackPoint, but hey I also like the Keyboardio. If only there were a way to combine the two.
I purchased and promptly disassembled a Lenovo TrackPoint USB keyboard, just to see if this could ever work. It works pretty well. In place of the three TrackPoint buttons (for the three mouse buttons), I mapped Layer 2 for three of the bottom keys on the Keyboardio, so clicking is as simple as holding down Fn and pressing a key. It works surprisingly well, but obviously it would be ideal if I didn’t need a separate connection for the TrackPoint keyboard’s logic board, which seems to contain a controller for the Trackpoint “joystick”. This means I likely would not be able to integrate the TrackPoint within the Keyboardio enclosure without a custom PCB with that controller. Also, placement is difficult because of that relatively-inflexible ribbon cable connecting the logic board to the TrackPoint stick. Thankfully there was plenty of adhesive in the TrackPoint USB keyboard enclosure that I used to stick the logic board and TrackPoint stick to the Keyboardio.
It is very shabby. Not bad for 30 minutes though. Open to suggestion from smarter people for how to make this better.
