The Jumbo Single Digit Clock below has always been a fun kit for those looking for a quirky clock, but what if you want the whole clock!? Well, we finally have the answer! This kit

combines four of the jumbo seven-segment displays below into one giant display perfect for offices, computer rooms, and shop windows! Not only does it display the time in your

choice of either 12 hour or 24 hour formats, it can also display temperature in Fahrenheit or Celsius! A bonus mode cycles automatically between your choice of time, temperature

and OPEN or CLOSED (“CLOSED” scrolls across the display) or a combination of the three. Easy-to-use controls let you set the time and switch modes. You can even put the

OPEN/CLOSED switch in a remote location so you can toggle easily from the other side of your shop! And it even has a secret bonus feature: hold down the “HOUR” button and apply

power and it will display the AC frequency of your power grid! The entire clock is ready for easy wall-mounting and measures 9" W x 2.9" H x 1.26" D. From Velleman.

The Most Unique Clock You’ll Find!

But Don’t Take Your Eyes Off It!

Jumbo Single Digit Clock


This 4 digit Nixie tube clock is the perfect "little brother" to our latest IN-14 and IN-8-2 series Nixie clocks. If you're not familiar with Nixie tubes or their history,

check it out on the previous page. In short, while once the standard for digital displays, they have since (and since meaning a long time ago!) been replaced by

LED, LCD, and Vacuum Fluorescent displays. Nixie tubes were considered cold cathode tubes filled with neon gas with a wire mesh anode and a set of very intri-

cate cathodes in the shape each of the numerals to be displayed.

This little clock uses 4 ZM/GN series nixie tubes that measure approximately .7" in diameter by 1.8” high. The hour/minute separator is a classic NE2 style neon bulb. The clock fea-

tures 12/24 hour modes, 12VDC operation with a quartz crystal timebase, programmable leading zero blanking, programmable AM/PM configurations, programmable night mode,

and supercapacitor backup. Like its big brother, this little clock also features blue LED tube illumination, allowing you to program the display mode as well as 10 day and night levels.

For a perfect vintage look, this little beauty is available with our signature teak hardwood base, hand crafted and rubbed to a furniture quality satin finish. For a futuristic look, our

see-through acrylic base allows you to look inside the clock to see the entire circuitry as well as the tube display. The choice is yours! The clock is designed around a quartz crystal

controlled timebase for high accuracy and zero dependency on incoming power line frequency, therefore, making it compatible throughout the world! The clock runs on 12VDC at

500mA, and our 90-264VAC green level-V power supply is included. From the soft Nixie tube glow, the LED tube illumination, to the choice in bases, if you're looking for a small com-

pact Nixie clock, this is it!

(Note: Various tubes from the Z5700M, ZM1082, GN-9A families and other pin-compatible tubes may be supplied with this kit, according to tube availability)
