The initial idea of that project was a Nixie tube clock which has a flat shiny
stainless steel case and 6 pcs. 30mm Nixie tubes of the very rare GR10J (and
GR10J/F) types.

Kurzbeschreibung/ Short Description |
|
GR10J | Hivac | B26A | 0-9 | 30 | Der "Numicator" mit der
kupferfarbenen Anode ist meiner Meinung nach die schönste aller 30 mm
Röhren und deshalb die Queen of all Nixies! The "Numicator" with the copper colored anode is in my opinion the prettiest 30 mm tube and therefore the Queen of all Nixies! |
|
GR10J/F | Hivac | B26A | 0-9 | 30 | GR10J mit rotem Farbfilter - extrem selten!/ GR10J with red filter coating - extremely rare! |
You'll find all technical data about that tubes here at my Nixie Tube Data Archive.
The Power Supply:
I used the same circuitry as for the
V600 Nixie Clock
Here you see the very first test- and improvement-board:
Next step was a self made milled
board for a SMD-circuit in an elongate shape - fitting perfect for the later
clock PCB:
TOP:
BOTTOM:
Note that this is a double sided PCB and was milled at a self made milling
machine.
Many thanks to JR electronics who built this machine and generated the G-code
for the board!
The finished and optimized test board:
It worked perfect for 170V/30mA at 90% efficiency with input voltage 12VDC. This
is very high for a step up converter.
It remains nearly hand warm at full load and works nearly noiseless.
GREAT!
The clock PCB
was the next I designed.
Here you can see the final version of the board:
BOTTOM:
TOP:
the blue layer you see here over the tube pin pads is not huckleberry jam but the solder mask, which protects the pads from soldering while the
boards run through the solder wave.
The assembling
could be done now.
The next pictures show the assembled board. The first prototype was hand
assembled and worked perfect.
BOTTOM:
On top right you can see the PSU taken over from the PSU design above with
little changes.
On the top left you see the buttons, the RTC, an ATMEG8515.
On lower side there are the Supertex (Nixie) driver chips for the direct drive.
All in all this super flat board provides a total height of 13mm.
SUPERB!
TOP:
You can see the self made tube sockets here. So the tubes easily can be replaced
and aligned.
The first prototype was born:
Next step: Designing the
case
I made some designs and ended at this
stainless steel cubic style (first a 3D-animation only)
The first prototype case was
done:
It is a laser cut stainless steel sheet, welded
and grind.
The dimensions of the case are: 250 x 80 x 27mm (only!)
Check out the wonderful surface

The clock at night:
Here you can watch a video which shows the V600-NT
clock.
This type does have the same case and features as the Nixie Queen clock, so you
can imagine the look of it:
