README
README.mdThis is a repo containing all docs related to Slack, a custom plank style keyboard meant for being used while relaxing.
There are 2 prototype revisions planned, each one getting closer to my ideal. Experimental modules will be hosted here as well.
Any revisions pass the second revision will be for refinements.

Questions
How big is the Example scrollbar PCB?
It measures 60.2 × 46.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Example scrollbar use?
10 parts, built around the EC10E1220505 and LTST-FC12WEGBD-5A. 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 Example scrollbar KiCad files?
From the Dreamy-Jy/slack repository on GitHub, at the commit this page was made from: the board is hardware/v1-mechanics/scrollbars/example_scrollbar/example_scrollbar.kicad_pcb and its schematic hardware/v1-electronics/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Example scrollbar design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dreamy-Jy before reusing the design.
