README
README.mdHomeTap
A haptic button that connects to HomeAssistant
I always wanted a premium button that is simple and only does a few actions - Toggle the lights on and off and change the color of the LEDs in my room.
Design
For the design, I used a very simple and minimalistic look, while looking sleek and modern.
It features a LED ring made out of 24 RGB LEDs that light up when the user's finger gets close to the button. This design is inspired from the prototype steam box.
Schematic and PCB
This device features a custom pcb. I used kicad.

Questions
How big is the HomeTap PCB?
It measures 76.3 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HomeTap use?
67 parts, built around the MPR121QR2, WS2812B-2020-V6, CL21A106KOQNNNE and RT1206BRD0775KL. 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 HomeTap KiCad files?
From the Mateix10/HomeTap repository on GitHub, at the commit this page was made from: the board is PCB/HomeTap/HomeTap.kicad_pcb and its schematic PCB/HomeTap/HomeTap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HomeTap design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mateix10 before reusing the design.
