K155ID1 driven IN-12A or IN-12B tubes for hour, minute, seconds. Use 36k resistors on these tubes. BS108 driven IN-6 or similar 410mm neon bulbs for digit separation. Use 270k resistors on these bulbs. 74HC595 for serial to parallel conversion ESP8266 for time synchronization. Use 1k resistors for pull-up. LM1117-3.3V and LM1117-5V regulators 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

Nixiesp12: common questions
What microcontroller does the Nixiesp12 use?
The Nixiesp12 is built around the ESP8266, from the ESP8266 family.
How big is the Nixiesp12 PCB?
The Nixiesp12 measures 167.6 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Nixiesp12?
59 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Nixiesp12 design files?
From the laurivosandi/nixiesp12 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Nixiesp12 design in my own project?
The repository has no license, so all rights stay with laurivosandi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Nixiesp12 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
