Hackpad2

Q: How big is the Hackpad2 PCB?

It measures 113.6 × 61 mm and has 2 copper layers, 1.6 mm thick.

Q: What parts does the Hackpad2 use?

32 parts, built around the SK6812MINI-E. 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.

Q: Where can I download the Hackpad2 KiCad files?

From the borzoi388/hackpad repository on GitHub, at the commit this page was made from: the board is pcb/hackpad2.kicad_pcb and its schematic pcb/hackpad2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Q: Can I use the Hackpad2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask borzoi388 before reusing the design.

Fishpad

Fishpad is the 9-key fish-shaped macropad of my dreams with an OLED display and a rotary encoder. Uses QMK firmware and it will have VIA support C:

Features:

whole thing

9 switches and a rotary encoder! (sadly no click on the encoder :c)
128x32 OLED screen
LED underglow
Case that's supposed to look like a fish?

Case:

Sandwich mount! Made in Onshape. The case has 3 parts, a bottom, plate for the keys, and a top. (all different colors in the picture :D). Also has a fun mouth-shaped usb cutout.

PCB:

Schematic

PCB pcb

Made with <3 in Kicad. Silkscreen imported from Figma. Time spent on the pcb was journaled

Firmware:

Used QMK and used adafruit/macropad as a template since it had similar features to mine
Not entirely finished, I will be using VIA to change the macros and leds
I did add two layers of macros for now, one for gaming and one for drawing. Will probably change in the future!
