This is a tiny ESP8266 Wifi Nixie clock that I designed and assembled. The clock was used very briefly by myself, so it is pretty much new.

The enclosure is prited from stone white PLA but you can also easily disassemble it and make some wood/metal enclosure for it. Or print a different color cover, you will find the 3d models on project’s github page.

You can check out the project on github, see https://github.com/mcer12/Nick-ESP8266.

Hardware

• ESP8266 powered
• 4x IN-16 nixies are driven by 2x K155ID1 ICs (duplexed)
• The nixies are evenly lit with not visible cathode poisoning (the photos don't do it very good justice)
• Nixies are soldered in a castellated holes
• No visible cathode poisoning
• 170V is supplied by NCH8200HV boost converter
• Power consumption is around 2 watts on high brightness
• 3d printed case (stone white but you can print your own, link to thingiverse on github)
• Middle colon is made of WS2812 addressable LEDs and the light is reflected on the surface. Much nicer than using ordinary leds / neon bulbs as a colon (arguably :P)
• It has a microUSB connector for power, can be powered directly from USB port or USB charger.
• Screwless, can be easily disassembled
• I've made only 3 of these in total so there is a sense of uniqueness :)

Software

• Simple configuration web portal to set WIFI credentials and everything else
• Timezone settings including Daylight Saving time (optional)
• Cathode poisoning prevention
• Brightness settings + night mode
• OTA update support

Please note that the nixies were hand-made back in the day, they can differ a bit in shape, numbers are not perfectly aligned etc. The Soviets valued functionality over design perfection… this is part of the oldschool magic but also can trigger your OCD so check out the photos before you buy!
