Rodan Nixie Clock

This nixie clock uses tubes from my favorite manufacturer - Rodan. The tubes seem to have been purpose-made for clocks, though I haven't seen any example from the time period in which they were made. They are the CD-11, GR-524 and GR-574. These last two are very rare. The GR-574 shows AM/PM and the GR-524 shows the days of the week in Kanji.

The clock is driven by an ESP32-PICO and the time is set via NTP. It also features a full set of sounds including ticking, chiming, striking and alarms. Several sets of sounds are stored on a SD card and the user can select which ones to use.
