Just got mine up and running. im not super skilled at compiling the QMK code as this is my first ever custom keyboard. I tried to update the RGB limit in the source config. but the source was outdated with how quickly QMK updates. I couldn’t get it compile with the updated config so for anyone on the struggle bus with RGB 5 count limit on the pro micro C. You can only do 5 LEDS in a row . HOWEVER the pro micro doesn’t care if you attach multiple data lines to the Data feed and do rows of 5 leds to get past that limit.

@revere521 I aspire to be this skilled at coding in linux. What needed to be changed outside of the LED drivers and why couldn't they be used?

@IanBuxton_1518941 Its just practice and repetition really :) QMK changed drivers for the LEDs, as well as moving some of the definitions for the key matrix and a few feature switches from the C header files into json files. It does seem like they are trying to simplify things. I just started with qmk new-keyboard and then copied the info from the old files into the new ones until it worked. FWIW Copilot is also helpful in quickly finding answers to error messages too ;) (edited)

I love it. I used some low profile cherry switches and made low profile relegendable keycaps (and a relegendable knob) for mine. Also I apparently can't read because I ended up buying the wrong size oled... whoops! So mine's got a bit smaller (0.96") screen. I love the underglow and glad I got some translucent PLA for the base to really get it to shine through.

Solid num/macro pad. I'm going to see if I can get a Via version of the firmware so I can update macros and such a little easier on the fly! Great Print! (edited)

@revere521

@_bwprobably Awesome! i love the huge panic button! drop a link someplace for those caps too, that's a great idea. You could probably just add a little to the screen cover and be all set, its really hard to tell though. there is a VIA firmware already compiled as a remix on thingiverse, i'm revere521 over there too.

and I did get VIA to work (mostly)!

Works great. Had to update the syntax of the code to edit it, but the precompiled worked great.

@revere521 this is a very good starting pcb. I do not have time to make it, but I can give you pointers or review your plan. Can easily reduce the complexity by just soldering on a MCU board rather than having to make a the surrounding circuit, like oscillator, rst pin stuff etc.

@revere521

@ElectricFjord It was my original intention, if i make another iteration it will be with a PCB and i may take you up on the offer to look at it. I also haven't had time to dedicate to new designs this winter, maybe the spring will bring some changes there.

Hei, this is real neat and i am part way building it now, but i am having an issue. How is the encoder suppose to be wired? I have used them before, stand alone, but not as a part of the button matrix. Could you clarify which pins on the encoder you refer to in the diagram. GND, VCC, Switch, DT and CLK. Thank you in advance!

@revere521
Commented out in config.h
#include "config_common.h"
#define UNUSED_PINS
All the "USB Device descriptor parameter "

Add the "USB Device descriptor parameter " to the info.JSON file
"manufacturer": "revere521",
"usb": {
"vid": "0xFEED",
"pid": "0x6060",
"device_version": "1.0.0"
}

renamed these buttons
KC_NLCK -> KC_NUM
RESET -> QK_BOOT

@ElectricFjord Excellent!! i'm glad you got it working. I will try that later today, and see if i can upload corrected code too - thank-you!

Thank you!
Color is prusament pero chalky blue. I love it.
Keycaps are the keypad part of a super Mario themed set from AliExpress. Really happy with it.
Thank you very much for creating this model!

@revere521 which keyboard design is it shown next to in the second image? They look nice together. (edited)

@revere521

@edm00se Thanks! That was my one and only true keyboard splurge - its a Drop CTRL. Its a little pricey for a keyboard, but my office is also my home office for work, so i feel like i splurged for quality. Its a heck of a keyboard.

Nice model. I printed it in chalk blue PETG prusament.

@revere521

@carillan_586550 That came out really nice! i dig that color. Those keycaps with the retro digital font are sweet too. Well done!

I cant get the code to compile under QMK MSYS. Get the error "Layout "LAYOUT" has no "matrix" definition in either "info.json" or "<keyboard>.h"!". ANy fixes? (edited)

@revere521

@zuber5_495138 Sorry for the extreme delay with my response, somehow i missed these makes and comments - did you get it working? I don't know the QMK MSYS flavor of QMK, but there should be a zip file with all the firmware files to compile in a build environment. I think in QMK it still refers to the layout without calling a matrix, so that code may just need to be updated to fit the syntax of QMK MSYS
