Port Cheapino to Ergogen

[azzamsa]

Hi, @tompi

After trying several keyboards. I am in love with Cheapino.
Now I am trying to port it to ergogen for easy custumization in the future by other users.
Currently, I am adding the pinky cluster / outer / 6th column. It is hard to reach the top pinky key with my small hand.

I guess the stagger using the Measure Tool, but it is hard to get similar arc in thumb cluster.

It would be great if you can share similar measurement of Cheapino like what Corne did.

This is my guess so far

units:
  # Proxy Spacing Variables
  kx: u
  ky: u
  # Padding Variables
  px: kx + 2
  py: ky + 2

points:
  zones:
    matrix:
      key:
        padding: 1ky
        spread: 1kx
      columns:
        outer:
          rows:
            mod.skip: true
            bottom.skip: true
            top.skip: true
        pinky:
          rows.mod.skip: true
          key.stagger: 0
        ring:
          rows.mod.skip: true
          key.stagger: 10
        middle:
          rows.mod.skip: true
          key.stagger: 6.5
        index:
          rows.mod.skip: true
          key.stagger: -6.5
        inner:
          rows.mod.skip: true
          key.stagger: -2.5
      rows:
        mod:
        bottom:
        home:
        top:

    thumbs:
      key:
        padding: 1ky
        spread: 1kx
      anchor:
        ref: matrix_inner_mod
        shift: [-4, -4]
      columns:
        inner:
        middle:
          key:
            splay: -10
            shift: [2, -1.5]
        outer:
          key:
            splay: -20
            shift: [6, -3]
      rows:
        cluster:

The interesting values:

        pinky:
          rows.mod.skip: true
          key.stagger: 0
        ring:
          rows.mod.skip: true
          key.stagger: 10
        middle:
          rows.mod.skip: true
          key.stagger: 6.5
        index:
          rows.mod.skip: true
          key.stagger: -6.5
        inner:
          rows.mod.skip: true
          key.stagger: -2.5

middle thumb:

Current iteration:

        pinky:
          key.stagger: 0
        ring:
          key.stagger: 10
        middle:
          key.stagger: 6.5
        index:
          key.stagger: -6.5
        inner:
          key.stagger: -2.5

    thumbs:
      key:
        padding: 1ky
        spread: 1kx
      anchor:
        ref: matrix_inner_bottom
        shift: [-4.7, -21.7]
      columns:
        inner:
        middle:
          key:
            shift: [20.9 - ky, -1.27]
            rotate: -10
        outer:
          key:
            shift: [41.2 - 2ky, -6.9]
            rotate: -23

Glad you like it, I was using the skeletyl a while, but now I use cheapinos at work and at home, and my skeletyls are just gathering dust...

I guess they ought to fit my hands, since I actually designed it using measurements from just tapping on an ipad...

Perhaps you can use the vial config:
https://github.com/tompi/vial-qmk/blob/cheapinov2/keyboards/cheapino/via.json

or the zmk config?

Thanks!

Any reason you don't like using Sketetyl?

I really like the skeletyl, but Im unable to hover while typing, which you should do when using a curved keyboard i think...

I tried to measure distances and angles in kicad, and translating to ergogen, this should do it:

points:
  zones:
    matrix:
      columns:
        pinky:
        ring:
          key.origin: [-12, -19]
          key.stagger: 10
        middle:
          key.stagger: 6.35
        index:
          key.stagger: -6.35
        inner:
          key.stagger: -2.54
      rows:
        bottom:
        home:
        top:
    thumbfan:
      anchor:
        ref: matrix_inner_bottom
        shift: [-4.67, -21.69]
      columns:
        near:
        home:
          key.spread: 20.95
          key.stagger: -1.27
          key.splay: -10
        far:
          key.spread: 20.32
          key.stagger: -5.72
          key.splay: -23

But the thumb cluster looks odd.

It doesn't look like the actual build

Are we missing something here?
