pcb for this was made in kicad 8.99, case was made on the fusion 360 educational plan (windows) & the firmware is written in kmk
cryptpad is my submission for the hack club ysws program called hackpad (v2) where we build our own custom macropads from end to end including brainstorming by making a rough sketch with an idea, planning the layout for your board + making a schematic, making a pcb based on the schematic, designing a printable case design on cad software and writing your own firmware to fit your needs.
pcb (schematic + board)
you can find a preview of the schematic here and the pcb here
case (bottom + top + knob)
i followed the hackpad case guide and referred to the v1 workshop recordings to build my very very rough case (that i do plan on improving) and my idea for the coffin shaped case and the overall dark theme of my macropad was largely inspired by an innate need to be edgy and a monster high phone case i saw on etsy (see here) :3
firmware
fully assembled
build process (inspiration + challenges)
my idea for the coffin shaped case and the overall dark theme of my macropad was largely inspired by an innate need to be edgy and a monster high phone case i saw on etsy (see here) :3 i wanted my macropad to be a pastel goth draculaura (i have the same hair as her btw) themed combination of shortcuts that are most useful to me while i was working / relaxing on my computer
the most challenging part was finding the time to revamp the project from scratch again and again since i had some difficulty narrowing down which components i wanted to use and what i wanted my layout to look like. i have SO many hobbies and interests so it was hard for me to pick an aesthetic (im currently revamping this project yet again) and each time i created a new board, i started grasping some additional pcb/cad concepts, making me want to include even more advanced changes to my board :3
i had to decide between a horror/gothic-y theme, a cute cat theme, a pastel theme, a detective/noir film theme and a pop-culture inspired theme. i wanted it to be consistent with my current vibes, interface with my current bedroom layout and be more neutral themed so i could even use it after the trends changed without being more queer/sapphic-y (that would out me) or more tech-y (boooo nerd !!!)

Questions
How big is the Cryptpad PCB?
It measures 63.5 × 113.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cryptpad use?
28 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 Cryptpad KiCad files?
From the arsoninstigator/cryptpad repository on GitHub, at the commit this page was made from: the board is pcb/cryptpad.kicad_pcb and its schematic pcb/cryptpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cryptpad 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).
