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

Aurora Corne low profile split keyboard wireless (lemmy.world)

Hi! I am excited to share my new build in this new community in Lemmy.

It is an Aurora Corne Low Profile keyboard. I just wanted to do a wireless split keyboard as thin as possible.

I bought all the pieces in splitkb.com:

Aurora Corne PCB (comes with diodes and choc hotswap sockets to be soldered)
2 Nice!nano v2 USB-C controllers
2 batteries 301230 3.7V 110mAh
Kaihl Choc low profile Orange switches.
Choc keycaps
Carbon fiber plate
Case (I have not bought any, I've just made a wooden panel, cutting it ad hoc), but I may buy one in the future or 3D print one, let me know what you think about it.

About the building process, I can say that I was afraid of soldering, but it was fun and easier than expected. I struggled a little more with the firmware configuration, because I was used to QMK but the nice!nano controller uses ZMK so it was a little different.

After configuring my Colemak layout and my layers on the firmware, the flashing process is pretty strait forward. Also the bluetooth connection integrated in the nice!nano was connected easily to my PC.

However, after 1 month of use, I have started feeling some issues in the left part of the keyboard, mainly with modifiers, such as Ctrl, Shift, Alt, and some letters. When I keep them pressed they are not recognized and I have to repress them. I don't think it is a firmware issue, because I have tried different configurations in ZMK and now all of them fail with the same keys, independently of whatever character I map on those keys. I am thinking that it maybe due to some diode that may be missoldered or some pin in the controller, because the first days it worked fine. And I have tested the same configuration as those days, and now I am getting these issues.

Any suggestion?

Seconded, that panel looks very clean. Nice job on it.

I had a couple solders on my corne leds that looked fairly good but didn't work reliably. Iirc, I removed and resoldered a couple connections, but reflowing may well be easier. Even fully removing was pretty quick and easy, so I think you won't have much trouble, especially knowing which keys are acting up.
