I have made this because i am frustrated how my kb handles music (it only has louder, quieter) so i wanted a slider like they have in actual studios.
wowie, how did you make such a cool thingie?
How?
- Firstly i downloaded libraries and imported them
- i added the components i wanted (xiao, neopixels, slider, buttons)
- i assigned footprints
- Layed them out on a pcb
- desgined a case according to dimensions
- Designed a lid with cutouts for all components
- Wrote this README
hows the binarys looking for this project?
I used:
- KiCad - For the pcb
- Fusion 360 - For the case
- Windows (no arch) - As a OS
- HackClub's Hackpad guide - https://hackpad.hackclub.com/guide

Questions
How big is the Hackpad PCB?
It measures 74.5 × 78.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
27 parts, built around the SK6812MINI-E and PTA6043-2015CPB103. 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 Hackpad KiCad files?
From the meepstertron/hackpad repository on GitHub, at the commit this page was made from: the board is pcb/Hackpad.kicad_pcb and its schematic pcb/Hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask meepstertron before reusing the design.
