My current project is a “Writer Deck,” a low-powered computer that boots directly to a text editor or word processor (RPi Zero booting to Wordgrinder, btw). Being the weirdo that I am, I also want to use this as an opportunity to try a split layout again, and see if I can get myself used to something other than the “Advanced Hunt and Peck” that I do now and that tops out at 60 or maaaaybe 70 wpm. The deasign I’ve come up with is a split monoblock based heavily on a Corne, but with a very modest split angle and the thumb cluster (1) shoved a bit farther under the hands and (2) built around 1.25u keys because they can be adapted to switch-stabilized 2.25u or 2.75u (see the green outlines). The whole thing fits in the Pok3r/GH60 footprint.
So, ergo-mech people, is this a completely silly layout? I have always felt that “literally never moving your hands” isn’t necessarily as ergonomic for the average typist as has been promoted, and I do like a good nav cluster, but I also wonder if I’ve compromised too much to hit that footprint, especially with moving the thumb cluster away from the center. The intended use case will be much more prose (journaling and other creative writing) than code, so I’m less concerned about optimizing for programming. I’ve never had major RSI issues myself, just needing to switch from a mouse to a trackball for a little bit every year or two.
I use a Corne daily. I don’t mind the idea of the center nav cluster, but I’ve been using Vim arrows on a layer (could also do WASD of course) for about a year and there are very few instances where I’d miss dedicated keys.
For me, this split angle is too shallow. Beyond that, the split’s ability to spread wide is a major boost to comfort that’s missing here. That said, This would be a great compromise versus a typical 60% or TKL.
Yeah, I guess theoretically I don’t even need to do a keyboard for the project at all. I did one other split a year or two ago, and I got too cute with the layout and just ended up not using it at all. Monoblock splits of many designs are obviously a thing, but one this small might be too much of a compromise to make it worthwhile.
Thanks for your input, and it’s definitely another point of view to consider. I’ve never made a “proper” two-MCU split (my first had hard-wired halves), but it might be an interesting design challenge to make one that could nest with the main unit. Most of my DIY boards are various 1800 permutations, so this is getting out of my comfort zone a bit.
