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

This is the first time I built a keyboard!
A cheapino!
It took a little bit of time to get everything figured out, but I was able to finish that build relatively easily.
However, I am having trouble customizing the layout... I can't load it in the qmk.fm tool and when I upload a json file it gives me something that doesn't match my keyboard.
Also, the encoder currently types 'y' when turned right, I got 2 thumb keys working as spaces and I don't have a modifier key.
As far as I can tell, everything is soldered right, the diodes are in the right direction...
Did I mess up my soldering or is the cheapino firmware buggy?
Any app that can help me flash/customize my keyboard? I'll keep googling.
Thanks!

Hey, thats a very nice build!

Im only using Mac, so I mapped the encoder to undo/redo, which on mac is LGUI+KC_Y/Z, but unfortunately not the same on windows. On windows gui(win)+y/z just equals "y/z", so thats why you get y and z when you turn the encoder.

Like @[email protected] says, you need to edit the encoder.c file to tweak it to what you want. If you cant figure it out, let me know how you would like it and Ill send you some code.

I checked the default keymap, and there is indeed double space there, I guess nobody has ever used it...

Anyway, what you want to do is go into keyboards/cheapino/keymaps and copy "tompi" to e.g. "chracoon", and then upload the keymap.json file to the configurator. When you are finished tweaking, download to same place and flash with "make cheapino:chracoon:flash"

Let me know if anything doesnt work.

And like @[email protected] says, I did indeed make a little bobo when routing the reversed RJ45, but fortunately it was pretty easy to fix in software, the matrix has to be custom anyway... There are some ghosting issues which I have not found the root cause for, but havent really hade the time to dig into it(just fixed the ones I found in software...) I suspect these are related to my choice of doubling the columns of the duplex matrix, instead of the usual row-doubling...

also just fininshed the hardware build and now - for the first time - try to get qmk on it. I cloned the repo just as in build guide and also installed qmk as per qmk docs. but when I issue

make cheapino:default:flash

I get

QMK Firmware 0.15.18 make: *** No rule to make target 'cheapino:default:flash'. Stop.

Any idea? I am also on Mac...

Hey. Cool! Send some pics!

Since there is no official qmk support for cheapino, you need to use my fork: https://github.com/tompi/qmk_firmware/tree/cheapino

I should maybe try to get my fork merged into official qmk…

For your question about miryoku, there isnt a super easy way. If you are confident with git and c, you can try merging my cheapino fork into miryoku.

I based my own keymap on miryoku, so if you start with «make cheapino:tompi:flash» you should be pretty close.

This sounds excellent. Will give it a try in a few hours and let you know. Maybe we can ask manna to include it into the official Miryoku builds, too.
