Nixie Lars User manual

Assembly Manual Miniature USB powered Nixie Clocks • Mainboard Rev.11-2013
Congratulations for purchasing this Nixie clock kit “Lars“ or “Laura”.
For successful assembly of this kit please read the following helpful hints.
• This kit is designed for someone who has advanced experience with assembling electronics.
• If you believe that the kit is too complicated for your skill level please do not try to assemble it - this
generally ends up with a device that is not repairable and results in you being very frustrated.
Please contact the provider and they can offer you other options that will end in a more fulfilling
result!
• Take your time - this kit should take 2 hours to complete if uninterrupted. Assembling the kit in a
hurry will lead to frustration and troubleshooting takes three times as long.
• Ensure your work area is well lit (daylight preferred) and clean.
• Electronic tools, such as pliers, small side-cutters or tweezers will be handy. You will also need a
T10 (Torx) Allen screwdriver for the housing assembly.
• A soldering iron station with a 1 mm round tip (maximum) and a 0.5 mm (maximum) fine electronic
solder (lead-free) is required. For lead-free solder we’ve had good experience with type Iso-Core
EL Sn95,5 Ag3,8 Cu0,7 with 0,5 mm Ø and 3,5% Flux from Felder Löttechnik and a 400°C soldering
tip temperature.
• For the intermediary function test you need a multimeter with at least 200 VDC range.
• A loupe (magnifying glass) to read the small device markings is often helpful.
• Assemble the board in the order as stated in the instructions - this has been proven and will
minimisemistakes.
• It is assumed that you understand that semiconductors (diodes, ICs, transistors) or electrolytic
capacitors are polarized components. Appropriate markings are silk-screened on the PCB and
shown on the board schematic.
Together with this construction guide there are some other usefull documents for
download
• The owners manual for this Nixie clock kit
• The owners manual for the BR-355 wired or “Wireless GPS Connection” system
Safety precautions:
During assembly, operation, measurements and maintenance extra precautions must be taken. The
generated high voltage of 160 V is dangerous. Assemble the circuit at your own risk.
The clock’s functionality cannot be guaranteed when assembled by the customer.
No responsibility can be taken for any personal claims and damages during assembly and
commission, especially for damages based on insufficient technical knowledge.
The Nixie clock may only be operated in a solid and moisture-proof enclosure.
The person who completes the kit and assembles this board into an enclosure for operation is
considered by the German directive VDE 0869 as a manufacturer and is required to indicate their
name and address including all documents when selling the clock.
Ready-to-go devices, which are assembled from kits, are counted as a safety-related industrial
made product.
Okay, and now, Ladies and Gentlemen – start your soldering iron...
As you might notice, most of the electrical parts are just pre-assembled and soldered.
However, we recommend to check these SMT assembly for assembly faults and cold solder pads
before assembling the through hole components.
You’ll find at the end of the manual a detailed assembly silk screen for reference.
Start with soldering the 32-pol. female header, fitted from the solder (!) side.
Following fit and solder both 28-pol. IC sockets (pay attention for the notches as shown on the silk
screen, the crystal, the potentiometer, the Super Capacitor and the buzzer. The polarity marking on the
buzzer is negligable but keep care for the correct allignment of the Super Cap (arrows on the part
package and the silk screen). Do not insert the ICs at this stage !
Next solder the 47uH shielded inductor, than bend the leads of the RFD3055L MosFet and solder them.
Take special care as this is an ESD device, so it is a good idea before handling this part that you de-
charge yourself on a metallic part of your desktop. The heatsink can have contact to the left hand’s
inductor pad; this doesn’t matter at all. Finally add the remaining parts like the 2u2 / 350V capacitor, both
dual LEDs (take care for the colour), both dual switches and the mounting bracket.
Notch on socket and HV5812
Finally cut and remove the tape from the 2.200µF
capacitor. Please do not simple cut the wires at
the top of the tape as the remaining lenght will be
too short.

The following task must only be done when assembling a Laura
Nixie clock
Pick up the 4 x M3 x 8 self tapping screws and the 4 x 3 mm plastic spacers
and threat them to the drilling holes at the edges of the main board. The
spacers are a self fixing type.

Assembly Manual Miniature USB powered Nixie Clocks • Mainboard Rev.11-2013
A note for handling the
IN-2 Nixie tubes
Please be very carefully by
handling the IN-2 tubes.
The glass bottom is very
fragile and will brake when
applying hard force,
specially when inserting
into the socket or by
aligning the tubes. You
need not to press down
the tubes fully into their
sockets. Only the half is
much enough.
Crack
Now connect the PCB to an USB power supply and check if something strange will happen; e.g. a
parts runs hot. If everything is allright we will do follwing some voltage checkings:
Please check the voltages on the PIC’s socket pins with a multimeter. Put the negative probe
(black) on TP3; left hand from the buzzer. Put the positive probe (red) on the socket pins.
Measured Voltages
red = ca. 5 V • blue = 0...3 V • amber = ca. 0,3 V • green = ca. 0...-2 V • black = 0 V
Pin 1 • Pin 2 • Pin 3 • Pin 4 • Pin 5 • Pin 6 • Pin 7 • Pin 8 • Pin 9 • Pin 10 • Pin 11 • Pin 12 • Pin 13
Pin 14 • Pin 15 • Pin 16 • Pin 17 • Pin 18 • Pin 19 • Pin 20 • Pin 21 • Pin 22 • Pin 23 • Pin 24
Pin 25 • Pin 26 • Pin 27 • Pin 28
Check following the voltages on the other testpoints: TP1 (around 4.8 V) • TP2 (around 4.5 V)
Please do not proceed until all voltages are within their range and check for the fault.
If everything is ok, unplug the clock from the power supply.
Solder now jumper ENABLE HIGH V. CONVERTER X1/X2, direct above the inductor and insert ONLY
(!) the PIC, but not the HV5812 driver. Keep care for correct orientation. Turn on the clock again.
Caution! Now the HV converter is working. Please check again, if something strange happens;
e.g. if a part will run hot. Pick up now a screwdriver and do again a measurement of the voltage on
TP1 It should be in the range of 40 V. Adjust now the voltage with the potentiometer to 41 V.
Do following a voltage check on TP2. It should be in the range of 165 V.
Push now button SET. The clock must make a short bleep.
Unplug the clock again from power and wait 10 secs. until the capacitors are discharged.
Now insert the remaining HV5812 driver IC into its PLCC28 socket.
Stop here and flip the page. You need now assemble the tube board according to your
clock. When ready assembled come back for a quick test of the tube board.
Now fit the tube board onto the main board and turn the clock on again.
The tubes should start with a „digit test routine“; which counts all digits. Also the (RGB) LEDs are
checked within this routine with the following scheme:
digit 1 = red • digit 2 = green • digit 3 = blue • digit 4 = none • digit 5 = green/orange
digit 6 = none • digit 7 = violett • digit 8 = none • digit 9 = cyan • digit 0 = none
The amber column LEDs should continuously light up.
If everything is ok, unplug the clock again from power and wait 10 seconds.
Solder now jumper ENABLE POWER BACKUP X3/X4 direct below the dual LEDs.
Solder jumper A-B-C direct below the ASK module connections to position A-B.
Now flip the page again and assemble the enclosure to finish your clock.
The following task must only be done when assembling a
Laura Nixie clock
Pick up the 4 x M3 x 8 self tapping screws and the 4 x 3 mm plastic
spacers and threat them to the drilling holes at the edges of the main
board. The spacers are a self fixing type.

Description
InitialRelease
Error correction / added replacing diodes procedure
Error correction / parts value of resistor-arrays changed
Changed the range of the voltage measuring values
Added assembly of Lena Nixie clock
New issue for the new main board version Rev.11-2013
Error correction and additions in GPS receiver settings
Corrected value of the measured voltages on PIC socket
Adding settings for DCF / NWTS receivers
When using theASK module from the Wireless GPS Set 3, simply fit the module onto the mainboard and
solder the 8 pins. Pay attention for correct orientation (see pictures).
Theclock has a build in antenna. However,due to the RF shielding of thealuminium profiles the reception
range is very limited. If the reception is too poor you can connect the supplied external antenna to the
TIME DATA connector. Don’t forget to set option #12 to value 4 (for GPS reception) option #13 to the
baud rate and option #14...16 to correct the time offset according to your location; this offset is based
on standard time (not day saving).
The green LED below the module will show the received data as well as the DATA LED on rear.
Please note that it is not possible to connect any extra external receiver to the TIME DATA
connector when an ASK module is fitted, only the supplied antenna can be fitted.
Please check again, if the solder jumper A-B-C (direct below the module) is soldered in position A-B
when using the internal ASK module. For setting up the „Wireless GPS Connection“ system proceed as
stated in the appropriate owners manual
When connecting the wired extrenal MicroGPS / NWTS receiver from PVelectronics set the
jumpers A-B-C to position B-C set option #12 to value 4 and check for correct baud rate settings.
When connecting the wired external GPS BR-355 receiver from GlobalSat set the jumpers
A-B-C to position A-B and check for 4800 baud rate settings (option #13 to value 0).
When connecting the wired external DCF receiver from Mr.Nixie you’ll need to set the
jumpers A-B-C to position A-B and set option #12 to value 1 and omit option #13

Assembly Manual Miniature USB powered Nixie Clocks • Mainboard Rev.11-2013
Assembling the Lars IN-17 tube board and enclosure
Please crack carefully both PCB’s.
Assemble now the male headers (1 x 32-pol. and 3 x 2-pol.) and the 4 resistors on the tube board.
Flip the board and assemble the four LED’s. Slight over the LED’s wires 2 x 8 mm spacers each
(8 in total). Pay attention that the anode of the LED is the longer wire and it is marked on the silk
screen with an „A“. Solder at the beginning only one pad, than adjust the LED’s exact upright and
solder the remaining pad.
Pick up now an IN-17 tube. Please
note that one wire is missing on
each tube as marking for the correct
mounting direction. This missing wire
has also no Star Milling pad on the
PCB.
See the red markings on the picture.
Thread all tube wires carefully through the
Star Milling cut out. Bend all wires into the slots of the Star Milling
pads. Keep care not to cross any wires.
Cut the wires. Now solder only one pad.
Align the tube carefully for correct adjustment
by re-heating the soldered pad.
If you are satisfied, solder the remaining pads.
Please take care not to make any short circuits
between the pads.
Continue this task for the remaining 5 tubes.
Pick up now the LED board and solder the 3 x 2-pol. female headers and the 6 resistor arrays.
The „polarity“ of the arrays is negligable.

Assembly Manual Miniature USB powered Nixie Clocks • Mainboard Rev.11-2013
Assemble now the 6 RGB LEDs
but do not solder them yet.
The longest (thrid) wire is the
Anode, marked with an „A“ on the
silk screen
Fit the LED board on the tube board.
Align now all LEDs is that way, that
their lens will touch the drill hole in
the tubes plastic socket.
Solder carefully all LEDs. Take
special care not to make any
short ciruits between the LED
pads as the spacing is very
small. Take as less solder tin
as possible.
After soldering cut all leads.
Stop here: Turn back to the
assembly of the main board for
a quick function check of the
tube board.
Pick up one rubber surround.
Please take care for the correct
side. Remove from the front cover
the protective film on the copper
coloured side and insert the front
cover carefully into the rubber
surround
wrong side
Attach now the front to the tubes. From rear align the column LEDs that their lens will fit into the drill
holes of the front cover.
Pick up one enclosure aluminium profile and slide the main board into the lowest nut of the profile.
Attach following the second aluminium profile
Finally fix - starting with the front - the covers with the supplied screws (you’ll need a Torx Tx10
screwdriver). Don’t twist the screws by force and keep care not to cam out with your screwdriver
as this will scratch the cover or even damage the tubes
Finished assembling. Congratulations and have a lot of fun with your new
Lars Nixie Clock

2.5 mm spacing
Assembling the Laura IN-2 tube board and enclosure
Pick up the tube board and assemble first the 32-pol. male header. Solder first only one pad and
check for proper rectangular alignement of the header. When satisfied solder the remaining pads.
Now threat over every tube pin a supplied tube
socket pin.
Sometimes the tube pins needs to be bend a little
bit. Do this very carefully as the glass bottom is
very fragile.
Now assemble the four LED’s. Slight
over the LED’s wires 2 x 8 mm spacers
each (8 in total). Pay attention that the
anode of the LED is the longer wire and
it is marked on the silk screen with an
„A“. Solder at the beginning only one
pad, than adjust the LED’s exact upright
and solder the remaining pad.
Please note not to forget to give
around 2.5 mm extra spacing for
the LEDs as shown in the picture.
Insert following all six tubes with the tube socket
pins into their socket drill holes in the PCB.
Do not solder them yet. After inserting all tubes
align them carefully for equal spacing and tube’s
height. When you are satisfied solder now the tube
socket pins. Take care not to make any solder
bridges as the spacing between the pins is very
small. Do not trim the pins after soldering!
Stop here: Turn back to the assembly of the main board for a quick function check of
the tube board.
Please pull out carefully (!) all
tubes in that way that they are
only fitted around the half of their
socket pins lenght in the soldered
female PCB sockets.
Attach now the front cover to the
tubes, but do not remove the
protective films at this stage.
From rear align the column LEDs
that their lens will fit into the drill
holes of the front cover.
Remove both protective films from
the bottom cover and fix the board
on it with the 4 x M2.5 x 8 screws.
Remove both protective films from the first transparent distance holder. Remove the protective film
from the brass coloured side of the front cover and than from the rear side, which is self-adhesive.
Affix now the front cover onto the distance holder. Check for symmetrical allignment.
Do the same task with both rear frames (the engraved
rear cover do not have any protective film).
Fix the rear side now with the supplied four 3 x 14 black
Allan screws (you’ll need a Torx Tx10 screwdriver) onto
the aluminium side frames

Assembly Manual Miniature USB powered Nixie Clocks • Mainboard Rev.11-2013
Anode pins
Slide now the bottom cover
into the lowest notches of
the side frames.
After removing both
protective films from the
transparent top cover slight it
into the most upper notches
of the side frames.
Fix the PCB / bottom frame
with the supplied M3 x 6
Allan head screw on the
rear side.
Finally attach the front cover and fix it with the remaining 4 screws and add the 4 pcs. foam feed
onto the edges of the bottom cover.
Finished assembling. Congratulations and have a lot of fun with your new
Laura Nixie Clock
Assembling the Lena tube board and enclosure
Pick up the tube board and assemble first the 32-pol. male header. Solder first only one pad and
check for proper rectangular alignement of the header. When satisfied solder the remaining pads.
Now threat over every tube pin except
of pin # 12 (left hand from the Anode
pin) a supplied tube socket.
Sometimes the tube pins needs to be
bend a little bit. Do this very carefully as
the glass bottom is very fragile.
Insert following all four IN-12 tubes
with the tube socket pins into their
socket drill holes in the PCB. Take care
for correct orientation. Note the white
shrink tube inside the glas
bulb which marks the
Anode connection.
Do not solder
them yet. After
inserting all tubes
align them carefully
for equal spacing
and tube’s height. When you are satisfied solder now the tube socket pins from the bottom side.
Do not trim the pins after soldering!
Anode pin
Do not fit a socket
on this pin #12
Now remove all tubes and solder the sockets also
from the top side. Be careful not to solder the
socket’s holes. Use as less solder tin as possible.
When finished attach the two 3 mm LEDs with two
8 mm plastic spacer each to their position. The longer
wire is the Anode of the LED and marked on the PCB
with an „A“; the shorter wire is the Cathode, marked
with a ring.
When finished solderin the LEDs re-attach
the IN-12 tubes into their sockets again.

Assembly Manual Miniature USB powered Nixie Clocks • Mainboard Rev.11-2013
Pick up now both IN-17 tubes and remove their
plastic spacers. Now cut the leads in a kind of
a „spiral staircase“ as shown in the picture.
This will help you to easy fit the tubes into their
drilling holes, which should be done following
this cutting.
Solder only one wire first and adjust the tube
for correct spacing and allignment as shown in
the pictures. Than solder and cut the remaining
wires.
Unfortunately on the first batch of the tubes
PCBs one track is missing which causes that
the digit „0“ will not shown on the 1st seconds
tube. So pick up a piece of wire and add the
missing connection from the 10th seconds to
the 1st seconds tube as shown on the picture.
Take care not to make any short circuits.
Wirelink
Pick up now both RGB LEDs
and bend them as shown in
the picture. The longest wire
is the Anode, marked on the
silkscreen with an „A“. Finally
attach the LEDs to the tube board and
solder carefully the connections. Be
aware that the pad spacing is very low,
so use as less tin as possible to
produce no short circuits between
these pins. Check also not to make a
short circuit to the added wire link.
Stop here: Turn back to
the assembly of the
main board for a quick
function check of the
tube board.
Remove from the front cover the protective film from front- and rear side.
Note that the rear side is self-adhesive. Attach the front cover carefully at
the U aluminium frame and fix it with four of the supplied M3 x 14 black
screws.
Than slide the board from the rear into the enclosure.
Remove from the acrylic cover both protective
films and slide it into the most upper nut into
the U frame.
Remove from the rear cover the protective film on the self-
adhesive side and attach it at the U frame.
Fix the cover first with the M3 x 6 screw and following with the remaining
M3 x 14 black screws.
Finally attach on the bottom the supplied
transparent self-adhesive feeds.
Finished assembling. Congratulations
and have a lot of fun with your new
Lena Nixie Clock.
