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

I'm attempting (unsuccessfully so far xD) to build a sofle rgb with nice nano, I'm new to the hobby and have thus taught myself how to solder and use github lol as it seemed fun at the time. However my main resource to look up questions used to be reddit and well Yea, fuck spez.

So my question is how come some of my rgbs are blue and some red? Is it my poor soldering job or do I have to flip the orientation some how? Any insight would be appreciated

My guess is the voltage - nice!nano has 3.3V on the VCC pin, while the pro micro has 5V (there might be 3.3V variants, but the shops I checked have 5V variants). The SK6812 LEDs are specced for 5V.

That said, mine worked well so far running on 3.3V, but when the battery was low some colors would not turn on.

Bear in mind that my board is handwired (and has fewer LEDs) and I only quickly checked the Sofle build guide (it might have a separate voltage regulator for the LEDs).

Anyway check voltages and if you indeed have 3.3V you might be able to work around it by swapping the LEDs out and hope the replacements are more tolerable to the lower voltage.

Happy hacking!

Thank you ! turned out my soldering job was just shit. Haha. I went over them and got every LED except the last two column working There's a break somewhere in the chain I guess but I haven't figured out where yet.
