Overview
Nudge is an open-source printed circuit board by Danneshowrang, from the Danneshowrang/Nudge-ADHD-Device repository on GitHub. It is a 4-layer board of 35 × 42.7 mm with 7 parts on 26 nets, routed with 62 tracks and 13 vias.
It is built around the DRV2605LDGS. Its parts include 2 capacitors, 2 ICs and 1 switch. It belongs with the ESP32 and RISC-V boards of this library.

What is it
Nudge is a haptic feedback device made to combat ADHD-related time blindness. It does this by stimulating the user ever 15 minutes with a haptic effect.
Why I made this project
I made this project because I, as an indivdual with ADHD who is heavily affected by time blindness, have missed a lot of opportunities, deadlines, and dates. (just now I missed the Stasis deadline to recieve a 150-point discount) I hope that with this device, I, and others with ADHD, can create an artificial perception of time and live life with less regrets.
Future Plans
In the future I want to expand this device to not only be a Time-blindness solution, but an entire ADHD multitool. This means adding additional features such as calendar reminders, built-in focus timers, date countdowns, and a user-interactive display.

Questions
How big is the Nudge PCB?
It measures 35 × 42.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nudge use?
7 parts, built around the DRV2605LDGS. 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 Nudge KiCad files?
From the Danneshowrang/Nudge-ADHD-Device repository on GitHub, at the commit this page was made from: the board is Nudge.kicad_pcb and its schematic Nudge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nudge design in my own project?
Its repository states no licence, so its author keeps all rights: ask Danneshowrang before reusing the design.
