NCV3.1-16 is the full nixie clock kit including four IN-16 nixie tubes. The kit contains all required electronic parts, preprogrammed microcontroller, fittings, printed circuit board, column separator bulb and nixie tubes (78 parts in total). Not included are enclosure and wall-cube type power supply.

The clock is professionally designed using the cutting-edge tools and technologies. Printed circuit board is routed with considerations to requirements for SMPS, signal interference, shielding and heat dissipation. Here is no doubt - you will feel quality from the first sight. To ensure easy assembly, no tiny SMD parts were introduced. Best, FR4 type material is used for the PCBs.

All electronic parts are the best quality and comes from the famous producers such as: Philips, Microchip, Texas Instruments, STM,  Maxim-Dallas, International Rectifier, Yageo and others. The Nixie tubes are New-Old-Stock and comes mostly from Russian military plants.

The clock's firmware is driven by Round-Robbin scheduler. Several industrial protocols are involved and dozens of tasks and algorithms are coded. It is quite complex and contains many thousands of code lines. It is programmed so that all settings and tube's lifetime counter values are stored in the internal EEPROM memory and are kept safely during the power outage.

Current version of firmware: v2.0.
