I'd suggest also adding blank modules without a switch on them for empty space on the keyboard (for example around arrow keys), that would still provide the interconnect to adjacent keys. Cool project.

A while back I was frustrated when wanting to buy a keyboard that there were no triangle-shaped keyboards or circle-shaped keyboards. This lack of peculiar keyboard shapes gave me the idea to make a keyboard that could be reconfigurable into any shape my heart desired. I’m still working on the firmware and making more keys but I wanted to share my progress so far. Heres the source if anyone’s interested in how I made it: https://github.com/notaroomba/keybytes

I like the idea but I could only find an image of two keys. It would be great to see a demo of a full layout. With only two keys it's a very early POC and hardly a keyboard.

Does communication work well and feel snappy with a full set of keys? How is the structural integrity of a full one? Can it be easily moved around? That type of questions could easily make this unusable at scale.

The I2C has limit of 127 of different addresses. Also there can be I2C hang, especially when there is that many slaves on the bus.

Maybe using CAN is better.

This is awesome!

How does the rigidity of the keyboard hold up with many keys and what's the cost of the materials at higher order quantity?

The keys are attached to a board so it can be in any orientation

Sometimes my keyboards get dropped and lose a keycap or two, but never anything serious. If this is dropped on the floor, my trusty keyboard will turn into a bag of puzzle bits, right in the middle of heated gameplay or a meeting...

This is a really neat idea for a macro keyboard. If it supported staggered rows and row heights, not to mention structural rigidity it would be good for everyday use too.

Is there a mouse module? Can you connect in a "staggered" manner rather than in a linear grid?

This is very cool.

It needs spacers / extensions so it can be laid out as desired.
