Overview
The NeonMatrix 8x8 matrix uses common neon indicator bulbs to display simple graphics.
They can be chained and controlled directly via SPI.
Operating voltage is about ~70V AC.
The circuit is pretty dangerous, all neon bulbs have high voltages on their legs, the 74HC595 shift registers are floating at mains/AC potential.
Safe data in/output is realized through 3 ADUM1200 digital isolator ICs and one B0505S DC-DC isolating converter.

Questions
How big is the NeonMatrix PCB?
It measures 116 × 116 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NeonMatrix use?
289 parts, built around the B0505S-1W, 74HC595 and ADUM1200AR. 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 NeonMatrix KiCad files?
From the Manawyrm/NeonMatrix repository on GitHub, at the commit this page was made from: the board is NeonMatrix.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NeonMatrix design in my own project?
Its repository states no licence, so its author keeps all rights: ask Manawyrm before reusing the design.
