Overview
Lathe RPM Display is an open-source printed circuit board by bytesizedengineering, from the bytesizedengineering/Lathe_RPM_Display repository on GitHub. It is a 2-layer board of 76.2 × 50.8 mm with 25 parts on 27 nets, routed with 155 tracks and 81 vias.
It is built around the KCSC02-105. Its parts include 9 resistors, 5 transistors, 4 ICs and 1 connector. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.

See project on YouTube: https://youtu.be/7gDZs0bImr0 I bought a wood lathe a few months ago and I thought it would be fun to make my own digital readout. The plan for this project was to use a hall effect sensor and a neodymium magnet to sense the rotations of the lathe spindle. I used an arduino board to read the sensor, count the pulses, and calculate the RPM of the spindle. I used seven segment displays to show the RPM reading. I designed a PCB and 3D printed an enclosure.

Questions
How big is the Lathe RPM Display PCB?
It measures 76.2 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lathe RPM Display use?
25 parts, built around the KCSC02-105. 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 Lathe RPM Display KiCad files?
From the bytesizedengineering/Lathe_RPM_Display repository on GitHub, at the commit this page was made from: the board is PCB/Lathe RPM Display.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lathe RPM Display design in my own project?
Its repository states no licence, so its author keeps all rights: ask bytesizedengineering before reusing the design.
