Title: Nixie i2c Clock
Post by: Elfish on Sep 02, 2014, 03:21 pm
Hi fellow Arduino enthusiast and nixie lovers,

i recently started to build my own nixie clock based on an Arduino. Why i wanted to do that? Oh well i like the shiny glow of nixies :P.
Anyway the real reason is that the builds that are available on the internet didn't fit my needs and i always wanted to programm some sort of ┬ÁC. I wanted a fully configurable clock including directly driven nixie tubes (no multiplexing).

I know the Arduino project since quiet a while, but i never felt like buying a unit and play with it.
But now i finally got a reason.

I decided to mainly use pre-made modules so i didn't have to design a pcb.
The following parts were used to build the clock.

6x SmartNixie IN-18 Socket >>>1361-SX<<< (
1x SmartNixie IN-12 >>>1328-SX<<< (
1x High voltage power supply >>>1364 HVPS-H<<< (
1x Real time clock DS3231 >>>DS3231<<< (
1x Temperature sensor >>>DS18B20<<< (
1x Adafruit HTU21D-F Temperature & Humidity Sensor Breakout Board >>>Link<<< (
1x Adafruit MPL3115A2 - I2C Barometric Pressure/Altitude/Temperature Sensor>>>Link<<< (
1x 5v step down power supply >>>Link<<< (
1x 12V wall power supply (old stock)
1x DCF77 reciever (old stock)
Misc. stuff such as resistors, pin headers, cables and mosfets etc.

6x IN-18 Nixie tubes >>>Link<<< (
1x IN-19A Nixie tube >>>Link<<< (
4x IN-3 Colon Dot

The SmartNixie modules are i2c adressable modules. It's very simple to drive them. They're well made and include everything you need such as a nixie socket and the ic logic.

My arduino sketch allows the clock to have quiet a few options such as:

You need your own website to show your projects  :P
Keep on glowing  8)

thank you.

i might open some blog to give more detailed descriptions once i'm done.
The attached picture shows the case that i planned.

we'll see how it looks painted etc.

i finally got the bare casing done and i could assemble the components for the first time.
Here's a picture of the clock so far.
It's still missing the symbol tube, because there are some screws left i need to shorten first.

Here is my Nixie Clock for I2C within schematic, PCB and software (

Looking cool, keep it up!
