Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Rolio 0.9 Update (lemmy.world)

Hi All,

Here's ht latest update to the Rolio split keyboard. It's now almost done, it just needs some minor cosmetic and manufacturability tweaks.

The GitHub repo is here: https://github.com/MickiusMousius/RolioKeyboard

A quick run down on the features (so far):

  • The keyboard itself
    • Fully wireless thanks to the Nice!Nano controllers and awesome ZMK firmware
    • Excellent battery life, I've personally been getting 2+ weeks before it gets to 60% with the previous iteration.
    • A low profile, compact choc spaced form factor that is similar to the Corne
    • Additional "Sometimes" buttons on the bottom row just like the Sofle
    • Horizontal roller encoders on both halves
    • A backlight that is efficient enough to be used on battery
    • A robust chassis so that it can be treated like a normal keyboard
    • An FDM version for at home low cost production
    • A CNC option for a slick look and very premium feel
    • A travel case that can easily be made using any FDM printer
  • ZMK Keymap & Custom keycaps:
    • The keycaps are fully customized and match the ZMK keymap thanks to FKCaps
    • MacOS and Windows modes as part of the keymap to keep the "same" handy macros in both OSs
    • All of the symbols and special behaviors can be accessed using at most two keys
    • The settings keys and different modes are documented in the key caps themselves (easy to learn).
    • The keymap can be easily customized thanks to ZMK, the keycaps can also be customized to suit your needs

Very slick! Love the custom legend key caps.

[–] MickiusMousius@lemmy.world 2 points 2 years ago

Me too, I highly recommend checking out FKCaps. The service is top notch.

This is my first time hearing about this. Looks really cool! Can you update some of the Aliexpress links?

These ones are dead:

  • 75V 0.15A Fast Switching Diode, SOD-123
  • EVQWGD001 Rotary encoder, dual channel, incremental quadrate outputs, with switch
  • Kailh Choc hot swap sockets PG1350
  • 30V Vds, 5.7A Id, N-Channel MOSFET, SOT-23

Links updated, let me know how you go!

[–] MickiusMousius@lemmy.world 1 points 2 years ago (1 children)

Thanks, I’ll get that sorted later tonight.

Are you wanting to build one or just being helpful for those that might want to make one?

I have a few spare PCBs of the posted iteration, if you’re based in Australia I’m happy to send some on. Though I’d recommend waiting for the 1.0 release.

[–] theUnlikely@sopuli.xyz 2 points 2 years ago (1 children)

I'm considering building one. I'm not in Australia and think I'll wait for 1.0, but thanks for offering! I haven't soldered anything in a couple decades. Do you think it's still possible for me to do this when a guide is made?

[–] MickiusMousius@lemmy.world 3 points 2 years ago

Yes. It’s fairly straight forward and there are test points to check everything is soldered properly as you go.

There is one exception, the backlight has some very small surface mount parts, the SMD resistors in particular are quite fiddly.

My current thinking is to sell pre-soldered kits with all the surface mount parts done (LEDs withstanding). This way people only need to solder the controller sockets and encoders to get a functioning keyboard.

I will of course keep all of the design files freely available. If you order your own PCBs from JLCPCB you will need to order a batch of 5 so you’ll have some practice boards 😊

I’m still working on a cost effective way to solve the pre-soldering of LEDs. I’ve looked into reverse mountable LEDs, but I’ve yet to find something that meets the required criteria (price, color, efficiency and availability).

Nice updates. I don’t know if it can give up my number row yet but I may have to consider it. Thanks!

[–] MickiusMousius@lemmy.world 4 points 2 years ago (1 children)

Thanks.

I am working on a similar MX design that has a number row (Rolio Max). In addition to the roller encoders it’ll have these bad boys too:

https://au.mouser.com/ProductDetail/Alps-Alpine/RKJXT1F42001?qs=6EGMNY9ZYDTsBzSTrhiL0w%3D%3D&mgh=1&vip=1

It’ll be much more of an at home board than one you can shove in a backpack. But I figure why not make an all you can eat board too.

I don’t anticipate having the prototypes even until December though as I’ve got a fair bit of work happening at the moment. In practical terms I guess that means no publicly available designs until early next year.

[–] drkhrse96@lemmy.world 2 points 2 years ago

Sounds cool. Look forward to seeing it.

[–] g0g0gadget@artemis.camp 2 points 2 years ago

Having had a full numpad on one of my layers for the last few years, I hate having to stretch my fingers all weird to hit 6, for instance, when using my laptop's keyboards with a number row.

[–] drkhrse96@lemmy.world 3 points 2 years ago

Yeah, I think I have to just buckle down and really get used to my layers. I got two orthos in front of me with different layers and I should just start practicing num layouts now.

[–] Necromnomicon@lemmy.world 3 points 2 years ago (1 children)

That is a mighty fine board you have there

[–] MickiusMousius@lemmy.world 1 points 2 years ago

Thankyou 😊

[–] nebula@lemmy.ca 3 points 2 years ago (1 children)

Curious, how well rollers work in that location? Are you using index finger or thumbs for those?

[–] MickiusMousius@lemmy.world 2 points 2 years ago

Index fingers, though you can use thumbs but that felt quite clumsy to me.

In the base layer they act as arrow keys. In the functions layer they are volume and zoom.

I’ve found the arrow key scrolling to be quite nice. It takes a little getting used to, but once you’re used to it regular arrow keys for text navigation feel clunky.
