Yet another Nixie clock project!
Some highlights:
- K155ID1 driven IN-12A or IN-12B tubes for hour, minute, seconds
- BS107 driven IN-6 or similar for separation
- ESP8266 for time synchronization and web interface
- LM1117 (3.3V regulator) for logic power supply
- No tube step up converter on-board, pin headers for connecting third party power supply
- KiCad design with 3D models from http://miniwatt.info
Some KiCad screenshots:
