Overview
Shift light is an open-source printed circuit board by jdrusso, from the jdrusso/shift-light repository on GitHub. It is a 2-layer board of 49.5 × 43.2 mm with 14 parts on 15 nets, routed with 70 tracks and 0 vias.
It is built around the LM317KCS. Its parts include 5 resistors, 3 ICs, 3 connectors, 2 diodes and 1 transistor. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdshift-light
This repository contains code for a Miata shift light, using a generic WS2812 individually addressible LED strip and ATTiny85 microcontroller.
CAD Files
The cad/ directory contains files generated in KiCAD for the PCB layout.
The included Gerber files should be useful in manufacturing this (as-yet-untested) board.
Circuit Design
Most of the circuitry here is just stepping the 12V tach signal down to 5V for the microcontroller to read it.

Questions
How big is the Shift light PCB?
It measures 49.5 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shift light use?
14 parts, built around the LM317KCS. 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 Shift light KiCad files?
From the jdrusso/shift-light repository on GitHub, at the commit this page was made from: the board is CAD/shiftlight.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shift light design in my own project?
Its repository states no licence, so its author keeps all rights: ask jdrusso before reusing the design.
