README
README.mdKiCAD STM32F0 Nixie Tube Clock
This repository contains the design files and assembly files for my nixie tube clock design. The code (firmware) can be located at https://github.com/bdebyl/stm32-nixieclock
The assembly files and docs are kept up to date to the best of my abilities.
Requirements
To use these design files you will require KiCAD >= 5.99.0, or simply build and install the latest KiCAD from their git repository.
Additionally, you will need my library files for proper viewing, and modification of the symbols, footprints, and viewing of 3D models:
Import these as either project or global libraries when opening the KiCAD project.

Additional Hardware
A custom model for an IN-14 holder or stand-off for 3D printing designed by myself is alos available via Thangs. This was designed to create additional height for the tubes on the PCB and aesthetic purposes (printed in black).

Questions
How big is the Nixieclock PCB?
It measures 120 × 93 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nixieclock use?
186 parts, built around the LT3757AEMSE#PBF, 74HC595, AMS1117-3.3 and BSS131. 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 Nixieclock KiCad files?
From the bdebyl/kicad-nixieclock repository on GitHub, at the commit this page was made from: the board is nixieclock.kicad_pcb and its schematic cathode_registers.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixieclock design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
