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 µC. 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<<< (http://www.tayloredge.com/storefront/SmartNixie/index.html)
1x SmartNixie IN-12 >>>1328-SX<<< (http://www.tayloredge.com/storefront/SmartNixie/index.html)
1x High voltage power supply >>>1364 HVPS-H<<< (http://www.tayloredge.com/storefront/SmartNixie/PSU/index.html)
1x Real time clock DS3231 >>>DS3231<<< (http://www.ebay.com/itm/DS3231-AT24C32-IIC-module-precision-Real-time-clock-module-memory-module-Arduino-/400503978923?)
1x Temperature sensor >>>DS18B20<<< (http://www.ebay.de/itm/Neu-Wasserdicht-Digital-Thermal-Arduino-Sensor-Temperatursensor-Probe-DS18B20-1M-/141289069832?)
1x Adafruit HTU21D-F Temperature & Humidity Sensor Breakout Board >>>Link<<< (http://www.adafruit.com/products/1899)
1x Adafruit MPL3115A2 - I2C Barometric Pressure/Altitude/Temperature Sensor>>>Link<<< (http://www.adafruit.com/products/1893)
1x 5v step down power supply >>>Link<<< (http://www.ebay.com/itm/DC-DC-Converter-Super-Mini-Step-Down-Module-Adjustable-3V-5V-16V-for-RC-Plane-/121292759932?)
1x 12V wall power supply (old stock)
1x DCF77 reciever (old stock)
Misc. stuff such as resistors, pin headers, cables and mosfets etc.

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:
- 24h time format
- auto sync time via DCF77 reciever.
- anti poisoning mode (slot machine + counter)
- night mode configurable for each day of the week (overrideable with a button for a definable time span)
- time display (pretty obvious since it's a clock ^^)
- temperature display
- date display
- humidity display
- pressure display
- configurable through serial commands
- "loop through" digit transition or no transistion configurable
- operating counter for the nixie tubes, so you know how long they were burning until now.
- clean up sketch
- make more stuff configurable
- build case for the clock
- make a video of the features and post it here
You need your own website to show your projects :P
Keep on glowing 8)
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.
