What HN said

What people liked

  • 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 HN
    • Wow. This is super cool. The magnets were a great idea!
      andai on HN
    • This 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…

Objections

  • 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 HN
    • Non-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 HN
    • This 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 HN
    • Extremely 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…

    • Hmm, 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…

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

  • 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…

    • This is very cool. It needs spacers / extensions so it can be laid out as desired.
      jasonjmcghee on HN
    • This 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?

  • 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…
