Rolio Progress (it works!)

I’ve been working on a design for a split keyboard that is a hybrid between a Corne and a Sofle.
So fair the electrical and software aspects work, I still need to sort out the chassis.
Some features:
- Efficient backlight circuit (at 100% it uses 20mA)
- Custom MBK Choc caps from fkcaps.com (the glow is awesome)
- ~250mAh battery (still low profile as there’s a hole in the PCB for the battery)
- Dual EVQ encoders
- Fully wireless using Nice Nanos
- The layout has MacOS and Windows modes
- Choc spacing
Once I’ve got the chassis done and I’ve cleaned everything up a bit I’ll open source it.
Here’s a preview of the chassis design so far:
If the GUI key is tapped twice it switches to the windows base layer, double tap again and it goes to the Mac OS (default) layer. This is done using a “tap dance”, look for “td” in the map to find it.
If you look at the conditional layers you’ll see how I accomplished the stacking of key bindings.
Since the board is naked I’ve not really used it, but I was playing with the scrollers and doing text navigation, it was very very nice.
I think you can share layouts from FK Caps:

The above is my current WIP. Hopefully it works, I’d like to share it as a basis for people to customise the Rolio if they want.
This could easily a game changer for me! My brain warps whenever I require a multi key/layer function, while I’m connected to a windows box from my mac.
Nice, I’m on mobile but will make a note to check this out later.
Honestly, this project, caps, and key map… I feel like you are me, lol
Glad to be of service. Check out the “lstart” and “lend” macros as a starting point for your single key to select a whole word thing.
I must admit I thought what I was doing here was pretty niche as I couldn’t find anything similar. Even the Bluetooth + Backlight seems a rarity. To be fair routing a 2 layer PCB with the added complexity was a PITA, soldering the resistors was super fiddly (either by hand or reflow).
The fact that it scratches an itch for you is pleasing, it means the added effort of open sourcing may be worth it as a few other people will get some value.
