t.1972 Nixie Clock

While browsing through eBay, this clock jumped out of the hundreds of thumbnails on the screen. This is one of the very few nixie clocks that actually takes a hanging form factor.  I can only think of one other design that was intended to be hung on a wall and this one looks significantly better.  Of course, there is a catch.  This comes as a kit and you need to assemble it.  However, for $179, it is still a great deal.

From the auction:

The hardware is an single-board PCB.It has an own switching power supply, two nixie drivers(74141) a high precision crystal and a PIC-microcontroller on board.It is supplied by a 9V AC 5.5mm jack.

The Software in the version V4.0 F is very easy and confortable controlled by only one button. That means you setup the clock and correct the speed of the crystal by following a menu with only one button.

You can choose between date-mode or time-mode (in date-mode only the to neonbulps bolow glow in time mode the four neonbulps are blinking(with fading). All events in the calendar such as leap years are considered.

The very special and new thing is the FADING  of the nixie-tubes and neonbulps. That means  that the ciphers are not only digitally switched but faded in change from one digit  to the other. For example the "5" disapears (gets dark) and the "6" appears (gets bright).

This clocks are intetionally not radio controlled, because then you could not use it in any place and the recievers would disturb the clear design of the clock  For a very high precision the clock's crystal can be trimmed by the software.
