PadIXFinal

Pad.IX, a custom 9 key macropad

this project is a spot where the code, schematics, 3d models, and other files related to the Hack Club Stardance "HackPad" project are located, with my iteration named "Pad.IX" since it has nine keys.

The Pad.IX is a nine key macro pad with an encoder and OLED screen, with future hopes of implementing VIA for custom keymapping.

CAD

The case was modeled inside of OnShape (A new tool for me) and renders (as seen above) were created inside of fusion 360. The case features a top piece which holds the switches and pcb, and a bottom piece to protect the electronics, with the two parts being bolted together with M3 bolts and heat press inserts. The case was somewhat influenced by the OZO Keyboards Skeleton Keyboard Case, but mainly it is just an interesting looking open shell design that appeared in my brain on the bus home from school!

PCB

the schematic and PCB are created using KiCad and LOTS of google.

Firmware

This hackpad uses QMK firmware for everything.

the rotary encoder changes volume. press to mute The 9 keys currently act as ma number pad The OLED is a status display of sorts (mainly says "Pad.IX" tho) Hopefully VIA support will be added once I actually build the thing irl

Thats pretty much it the firmware was pretty confusing to make so idk what to say

Author's Note

Thanks to the people at Hack Club this was an amazing experience! This is my first Hack Club build but I am looking forward to doing so much more in the future! Also thanks to google cuz this was VERY confusing!
