Overview
Schematics tube is an open-source printed circuit board by thekakkun, from the thekakkun/Callisto repository on GitHub. It is a 2-layer board of 35 × 31.9 mm with 3 parts on 23 nets, routed with 79 tracks and 0 vias.
It belongs with the lEDs and displays boards and the ESP32 boards of this library.
README
README.mdCallisto
Callisto is a digital clock that uses a Russian IV-18 vacuum fluorescent tube for the display. The clock uses an ESP32 to automatically sync time.
The name Callisto was chosen so that the name could be displayed on an 8-digit seven-segment display.
Features:
- Sync time, retrieved using WiFi
- Automatically switch to daylight saving time
- Clock display settings configured using web browser
- Automatic shutoff during night hours in order to decrease energy usage and extend tube life
- Auto-dimming based on ambient light conditions
Special thanks
The software and hardware design of the clock was stolen from heavily inspired by the following projects:

Questions
How big is the Schematics tube PCB?
It measures 35 × 31.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schematics tube use?
3 parts. 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 Schematics tube KiCad files?
From the thekakkun/Callisto repository on GitHub, at the commit this page was made from: the board is hardware/schematics/schematics_tube.kicad_pcb and its schematic hardware/schematics/schematics.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schematics tube design in my own project?
Its repository states no licence, so its author keeps all rights: ask thekakkun before reusing the design.
