Putting the PCBs together
Connect the display board to the main board.
You can now connect a power supply again and
run a first test. After power up, the nixie tubes
show the firmware version and should then
cycle between digits one after each other. Note
that the first nixie tube only can show numbers
between 0 and 3.
After the cycling test, the clock will show a baud
rate 4800 and then 9600 when it tries to get the
time from the GPS module.
Shortly thereafter, the time is displayed. Depending on your local time zone, this may be or not be
correct but this can be adjusted later. Please note that dimming may be active too resulting in a
very dim display. This can also be adjusted later.
Installing the backlight PCB is optional. The nixie
clock can work without the backlight PCB too. If
you don't want to install the backlight PCB, you
can skip the following steps and go directly to
the wiring of the clock.
Mount a 3 pole pin header to the solder side of
the backlight board. This board comes
preassembled with the SMT parts already in
place.
