Here are a
few photo's taken on 1/02/2003 of the 6 digit nixie clock I am building.
So far this is the layout of the 17 sockets soldered on my circuit board.
This clock will use TTL IC's. They are 7441 decoder drivers, 7490, 7492,
7410 and 7400. I am debating which Nixie tubes to use. I have about 110
Nixie tubes in my collection.
A little overkill
with the IC's but I am building it late 60's style!
to experiment on my mini breadboard. Here you see wired is a decade counter.
The IC's on this board used are 555 timer, 7490 decade counter and a 7441
decoder driver. The Nixie tube used is a National NL-5441a.
This is the
revised schematic of my 6 digit Nixie Clock
Here are some
photos of my Nixie Clock plugged in and working. It was a lot of
work to build
it this way but it was worth it.
Below is the wiring side
of the board. When I wired the board, I didn't realize I had all the IC's
I had to cross all the
wires from one side to the other wiring the Nixie cathodes to the 74141
Here are 2
photos of a 1 tube Nixie clock I built using a AT90S2313 Amtel AVR
James Sweet. I built 3 of these so far and gave 2 of them away as presents,
one of them
ending up in Saudia Arabia. I had to install the clock in a case so why
not use a
birdhouse! The photo on the right is the inside of the electronics.
to see my 40mm IN-18 nixie clock
the large photos. More photos to come as I
build my clock.
