README
README.mdBUCKPAD
hackpad for hackclub blueprint The buckpad is a 11 key macropad with a rotary encoder and a OLED display, and uses QMK firmware. The case is designed around the colors of gyspy danger from Pacific Rim, as it is one of the greatest films ever with NO sequel. It mainly serves as a macropad for everyday activity (listening to music, writing etc.)
Features: -11 keys -1 EC11 rotary encoder -1 Oled display
PCB
here is the PCB (first time ever i do one!), the silkscreen is imported from a Figma image.

Schematic for the hackpad
Case Design
This was my first time working with Fusion and, not gonna lie, i had a ton of fun designing this case
Firmware
This hackapd uses QMK firmware:
- the rotary encoder changes volume. press to mute
- the other 11 keys currently act as macros (thought i plan on implementing VIA to dynamically change them)
- I plan to set the oled as an audio visualizer once i get my hands on it.

Questions
How big is the Hacckulb PCB?
It measures 90.5 × 97.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hacckulb use?
30 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hacckulb KiCad files?
From the Thebucket-ops/BuckPad repository on GitHub, at the commit this page was made from: the board is PCB/hacckulb.kicad_pcb and its schematic PCB/hacckulb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hacckulb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
