Cool modular design and magnetic snapping
From 3 comments
I'm not sure if I have a use case for this but on the technical aspects this is so cool. Those magnetic snaps made me grin!
O_H_E on HNWow. This is super cool. The magnets were a great idea!
andai on HNThis is really cool I love the fact that it can be detached and placed in different sections. It makes it easy to move a key from one location to another without much hassle. I…

Well-polished PCB and schematic
From 1 comment
I looked over the PCB and schematic and it looks well polished. Not a first draft obviously. I sort of don’t get the 4x I2C busses. I’m probably missing something obvious but it…

Too expensive per key for a practical product
From 3 comments
at the cost of what per key? Congrats your removed all the efficiency from the system.
sleepybrett on HNNon-viable product. I would NOT buy this. - 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?…
M95D on HNThis is cool, but wouldn't it cost more than $2k for a 104-key keyboard? I can't imagine these PCBs having a final price of less than $20 each.

Pogo pin connections are unreliable and costly
From 2 comments
Pogo pins are expensive. Somewhere around $0.15-$1 per pin. This design has four pairs of two pins. So just the connectors are over a dollar per key, possibly multiple dollars

Only supports grid layouts, not staggered
From 3 comments
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.
IllIIlIlIlIIIIl on HNExtremely cool! Another commenter mentioned[0] that often ergonomic keyboards aren't columnar, but staggered. What if for the pin layout, instead of this: ``` 1 1 0 0 ``` It was…
schiffern on HNHmm, somethings wrong with my hosting, https://cpbergin.com/dyson2026 should work. It’s just the same video as in the submission. I mean I think the idea is worth pursuing, this…

Add staggered layout support

schiffern on HNIs there a mouse module? Can you connect in a "staggered" manner rather than in a linear grid?
eviks on HNThis 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.

Add spacers or blank modules for layout gaps
From 3 comments
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…
9dev on HNThis is very cool. It needs spacers / extensions so it can be laid out as desired.
jasonjmcghee on HNThis looks awesome! It would be even better with spacers or extensions to allow more flexible customization and layout options.

Show a full keyboard layout
From 1 comment
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…

Questions
How does the structure hold up with many keys?
From 2 comments
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?
kaipereira on HNI 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…

Are the connectors direction-agnostic?
From 1 comment
Fantastic work, I'm always excited to new modular input device projects like this. Are the connectors actually direction-agnostic? Looking at the layout it seems like depending…

Capacitive sheet under keys
From 1 comment
How about using a capacitive sheet under the keys, a software x/y map -> keystrokes and a simple passive blob under the keys? That might end up cheaper than this. Nice work…
