A smart nixie clock capable of automatically setting time and adjusting for timezones / summer time transitions.
Smart
- Time is set automatically through a web API
- A webapp is provided to adjust wifi settings, timezone, backlights and display sleeping times
The wifi settings are managed by esp32-wifi-manager.
A modern dispay driver
- SPI based driver
- No multiplexing of nixies
- No relying on old nixie drivers
Each pin is fully driven by its individual 300V NPN transistor.
A robust high voltage converter
- A modern flyback converter with top of the line controller
- No 555, no old 34063 trickery
The nixie clock is powered by a LT3757 controller and a big 1:10 transformer. The design can be found here. The last thing you need is for your clock to catch fire!
