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
