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.
