Ah, okay good to know you've seen those. Just wanted to check in case you missed something that suited you perfectly. It sounds like you have a clear image of what your ideal keyboard would be. 👍

Also I have no idea if I'm using the terms right either but I think the roller is the same as the scroll wheel? And rotary encoders would be those dial knobs.

I'm with you on having a trackball on the right half and a scroll wheel on the left, that sounds amazing. 😁

This one does have a “math mode”, if the numbers layer key is double tapped it locks in the numbers and other “maths buttons” until the numbers layer key is tapped again.

Next I’d like to make a macro pad that has a ten key mode for “home use” with some big rotary encoders that matches the style of the Rolio (to be called Twistio).

That said, I am tempted to make a split with a number row (Rolio Max?). If I do that then there will be enough room for a 5 way stick below the roller encoder, I couldn’t fit that in this one. But this would be more for “fun” as I quite like the Corne after having used both the Sofle and Corne.

That said, it’ll need to be much later this year, I have a CNC machine on order. I’d not want to prototype something like this again without a CNC machine of my own. The process is a bit expensive, the controllers and displays are a bit pricey too IMO (though still good value given what goes into making them).

Also wanted to chime in that I appreciate a more conservative pinky drop, as a compromise between ergonomics and keeping it useable while gaming with minimal rebinding (keeping the vertical stagger between the a and s keys in the usual wasd navigation cluster within a reasonable threshold since it'd be used with the ring finger instead of the pinky in those context)

I feel this is also inline with the apparent (I'm making some loose assumptions here) goals of being a little more newcomer friendly, along with the fact that it has a bit more thumb keys than what many consider optimal for ergonomics and other details. It really feels like the intermediate step between the typical entry point split ergo boards like the Lily, Iris, or Sofle and the more optimal ergo boards.

Pushing those additional eronomic quality of life tweaks may improve the board, but it also brings the board much closer in target demographic to existing boards like Hillside or Cantor/Piantor for example, and arguably makes this board less uniquely appealing.

I hope I don't come off too strong with my opinions here; The design middle grounds picked in this board so far really resonates with me in a way few others have that I can't help but get excited. 😁

on a different note entirely: Good callout/reminder on the pitfalls of over-relying on that tool in a way that reinforces existing habit that may not always be optimal.
