Linux-looking macropad?

Hardware

By @Krupam

  • 7 Devlogs
  • 25 Total hours

A 3x3 Macropad that has a rotary encoder and a OLED Screen with LED Backlighting. The rotary encoder will switch the layers on KMK. The LEDs will light up according to the layer as well as all change color. The OLED screen (up top) will display the current layer, an image, and the functions on the layer. On each layer the 4 different keys will do different functions.

Final Devlog Before Ship

Hey guys! I am so excited to get this macropad built. I finished setting up the gihub repo and added pictures and I am going to submit my design for review. Wish me Luck!!!

Prepare for Shipping

CAD:

Man this project has taught me how much I hate fusion 😭. But I had to learn it eventually right?
I added a 45 degree one inch feet to match with my keyboard. I also added small insert holes for me to put rubber feet (or more realistically hot glue).

PCB:

I spent some time error checking and making the pcb production ready. I created my own footprint for the XAOI to get it to fit on my pcb. I wanted the USB to stick out to reduce the length of cable required to go in.

Github:

I started putting all of the files on GitHub, check it out! My Github

Case work!

Hey hey hey, I know it has been like three months but I can explain…

Why so long?

Well to be honest, I do NOT like fusion. I hate geometry and by extension cad. This project is my first time ever doing it so it took a lot of youtube videos, advise, and procrastination to get here.

The Case:

The case is pretty simple, it has the top piece with cutouts for the OLED, rotary encoder, keys, as well as holes for the LEDs to shine through. (I will fillet everything at the end) It also has holes for the heat inserts to melt into. The bottom case has the actual walls of the case, holes for the screws, standoffs for the pcb, as well as the USB C cutout.

This is definitely not my cup of tea, so please let me know if anyone has any ideas.

FINALLY!

I finished writing all of the code for my macropad today. (I love procrastinating Fusion :) The macropad has a couple of functions. The rotary encoder will switch the layers on KMK. (0-2 right now but planned expansion to 0-4) The leds will light up according to the layer as well as all change color. The oled screen (up top) will display the current layer, an image, and the functions on the layer. On each layer the 4 different keys will do different functions

They are as such:

  • Copy, Paste, Redo, and redo.
  • CTRL + F, clipboard, File explorer, and Screenshot.
  • Pause/unpause, mute/unmute discord mic, defen discord, mute pc.
