ButtonMasher.exe

ButtonMasher.exe is a 5 key macropad (arranged in a D-pad shape!) with 3 leds and a rotational encoder!

Features and Inspiration:

• EC11 Rotational encoder for screen brightness control (finally I can stop irking about setting brightness on my monitor! (tbh I was too lazy to look up how to set macros before this))
• 5 whopping keys for epic macros: one should be set up to control the leds too!
• 3 WS2812B RGB LEDs

I wanted a macropad for various bindings I don't have: everything from screen brightness to song fast-forward/rewind are in here. Lots of variety!

CAD Model:

It's made of two pieces: a bottom case and top cover. I might rework this in the future to better show off the leds. I learned Fusion 360 basics to do it!

(PS I know these pics don't show the case in full. I've got the pcb model fitted though)

PCB

My PCB has some special sauce cooked up by a friend experienced in wojaks. I cannot confirm or deny who might be in those drawings...

Firmware Overview

This hackpad uses QMK firmware for everything.

I hope to add VIA/further RGB options in the future. (hackboard idea hmmmmmmm (:

Challenges:

I've never touched CAD or PCB design before, so almost everything I did had a learning curve. Especially fusion...

BOM:

• 5x Cherry MX Switches
• 4x DSA Keycaps
• 3x SK6812 MINI LEDs
• 1x EC11 Rotary Encoder (can I ask for a knob matching the case color?)
• 1x XIAO RP2040
• 1x Case (2 printed parts, in black preferably)
• 4x M3x16 Bolts (and nuts)

Feel free to look at the firmware or other files for inspiration! This was a fun project
