- How much does it cost? Sell price, not BoM price. I expect something like $10'000 for a full 104-key layout.
- How heavy would it be?
- Can you lift a 104-key layout from the table without it breaking in 2 (or more) pieces? Can you even lift or move a 40% layout with one hand?
- How do you arrange it in a non-ortholinear layout? If you can't, then anyone can just buy an ordinary ortholinear and switch layouts in software.
- How does the spacebar key look like? Enter key? Shift? I can't type if those big keys aren't big.
- How do you make spaces between key groups?
- There are a lot of pogo pin connections. It's statistically impossible for all of them to work. Is there any redundancy for those connections? Alternate signal paths with automatic rerouting? Any debugging tools/indicators to find where the bad connections are?
- If you have a MCU in every key, and at that price, I would expect them to have a mini-display in the keycap plus lots of other fancy features.
- How about automatic function assignment for each key based on it's location? Can it do that? If not, then any drop on the floor becomes a half-hour puzzle-solving problem.
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.
I am waiting on some key switches to make more keys (5 in total), but for now I just wanted to show the progress on the mechanical/electrical side. I donāt have enough PCBs for a full set of keys yet, but when the key switches arrive and I assemble the 3 other boards Iāll let you know how it goes :D
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. Iām still working on the firmware and making more keys but I wanted to share my progress so far. Heres the source if anyoneās interested in how I made it: https://github.com/notaroomba/keybytes
Itās really rigid with 2 keys so far but I have yet to test with longer configurations. At a higher order quantity, each key comes out to be around 6 USD but Iām trying to minimize that as much as possible with future revisons!
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.
There isnāt a mouse module yet, but I am going to make more modules that include screens, finger print sensors, and Iāll add in a mouse one too :D. Currently there isnāt support for a staggered manner but I am going to work on it for the next revision.
I looked over the PCB and schematic and it looks well polished. Not a first draft obviously.
I sort of donāt get the 4x I2C busses. Iām probably missing something obvious but it isnāt immediately apparent how the units all have addressing worked out.
The 4x I2C busses were mainly there to reduce parasitic capacitance and also allows me to know where each key is physically relative to each other in software. Iām still working on the firmware for it, but currently the plan is for each of the keys to remember its āparentā, the neighbor that is closest to the main board, and forward events repeatedly to the main board.
Non-viable product. I would NOT buy this.

Looking forward to seeing it!
What's the production cost of this per key?

Just a small suggestion but... maybe re-record your demo without giant floodlights on your desk? :(
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?
Thank you!!
Itās really rigid with 2 keys so far but I have yet to test with longer configurations. At a higher order quantity, each key comes out to be around 6 USD but Iām trying to minimize that as much as possible with future revisons!
Something similar: https://youtu.be/_u8gV643214
The keys are attached to a board so it can be in any orientation

The magnets are strong enough that most of it should survive lol. I will be doing drop tests to test that theory out soon

Thank you! I am currently thinking about adding those in the next revision and it would definitely make it more practical.
Is there a mouse module? Can you connect in a "staggered" manner rather than in a linear grid?
There isnāt a mouse module yet, but I am going to make more modules that include screens, finger print sensors, and Iāll add in a mouse one too :D. Currently there isnāt support for a staggered manner but I am going to work on it for the next revision.
This is very cool.
It needs spacers / extensions so it can be laid out as desired.

Iāve wondered when someone would do this (which gets rid of the annoyances of scanning).
The real breakthrough would be reprogrammable key legends in something like e-ink.
Very cool, would really like one
this is extremely cool. would love to see full board
Now give them all wheels so they can rearrange themselves on my desk
