Enclosure
The enclosure design has been moved to Fusion 360. The files in the hardware folder are out of date and will be removed at some point.
Build Instructions
The code was built on Ubuntu 16.04. The STM32Cube F3 library V1.9.0 will need to be installed to the /opt/ directory. The following apt packages are required.
cmake
gcc-arm-none-eabi
gdb-arm-none-eabiTo build the code.
mkdir firmware/nixie-clock/release
cd firmware/nixie-clock/release
cmake -DSTM32_CHIP=STM32F302C8 -DCMAKE_TOOLCHAIN_FILE=../../cmake/gcc_stm32.cmake -DSTM32Cube_DIR=/opt/STM32Cube_FW_F3_V1.9.0/ -DCMAKE_BUILD_TYPE=Release ..

Questions
How big is the Nixie clock PCB?
It measures 176 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie clock use?
106 parts, built around the STM32F302CBT6, MAX1771CPA+, LD1117S33TR(MS) and DDTD113ZC. 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 Nixie clock KiCad files?
From the jeffkub/nixie-clock repository on GitHub, at the commit this page was made from: the board is hardware/main-board/main-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie clock 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).
