Hello
Still more of a lurker here, but trying to wrap my head around my own take on a small 40%-ish keyboard. I got inspired by jdcarpe his JD40 project and the Dvorak 42% of Joey Quinn.
I am currently debating about 2 possible layouts and would appreciate some input for this community. I am looking for a Colemak compatible size, a split space bar (because I only hit with my right thumb, so I can have a use for my left thumb as well) and I want to try column staggering.
The space bar sizes are 2 or 1.75, I like the 2 unit size because it gives symmetry, but I am not sure if this then requires a stabilizer or not.
I will start with experimenting with kiCad to design a PCB, because I want to give a PCB a try (if it doesn't work out, hand wiring it will be)
[attachimg=1]
[attachimg=2]
As I am a slow learner and very tedious about what I do, don't expect a working keyboard in several weeks :-)

I like the first layout a lot. The symmetry is nice. And you won't need a stabilizer for keycaps of those sizes. Neither of your presented layouts will need a stabilizer.

Well, technically, any key over 1.75 units "requires" a stabilizer, but it will probably be fine without it. Just take the stabilizer off your Backspace key to demonstrate the difference.

I've been using my Epsilon without proper stabilizers in my backspace for a while. It's not 100% ideal but it works.
-
Main reason not to have stabilisers would have been not to think about those cut-outs and sourcing them. However, as I just started with the PCB design, and looking at the efforts I will have to put in to understand how a keyboard is designed, I shouldn`t fuss about incorporating stabilisers.
The first layout is really nice and I better take my time for it and design it properly. So 2-key it will be, with the possibility to add stabilisers.

This is already being done! See the Interest Checks forum for the Planck Keyboard thread.

Cool, thanks for the link. My goal is not to be unique with this project, or even to make this into a group buy. It's sole purpose is to give me the opportunity to learn and play around. But thanks for the link, I will have a good look at it.

Question about connecting the rows/columns to the pins of a teensy eg. Is there a specific order to consider? Haven't looked at the datasheets, so this is me being lazy by asking instead of looking this up.

Thank you for the guides, I will try to put them to good use this weekend. I want to finish the initial PCB design this weekend.
It has been very busy at work lately, several test- and rehearsal migrations that are just not doing what needs to be done. So lots of stress and not much spare time.

will be watching this thread carefully. 40% colemak, matias quiet click, programmable... now if you can figure out where to put the bluetooth and the battery... :)
