Yes, the dot has to travel, one point at a time, so when all pins are lit, 
the glow has to cover its maximum distance, hence the refresh rate slows 
down, and it does flicker. If I were to increase the clock rate to 16MHz 
(currently 8MHz), it will probably disappear. But to do that, I need an 
external clock, or xtal. One or two more IO bits that I don't have in its 
current incarnation.

I almost managed to get it coded inside 4K, which would allow me to use a 
ATmega48 chip, But that trimmed too many features. Currently the code size 
is about 5.5K.

I wanted to use the light pipe, and neons, even the brightest ones, really 
aren't bright enough. LEDs on the other hand can be too bright, if you run 
them at their recommended currents (~20mA). On this unit, the LED only has 
~8mA passing thru it.

Great work! I think yours is a step above mine given the custom case. I'm 
sure we both agree the neon glow is a really elegant match with wood and 
brass. I love the acrylic light-pipe design for the colons. Let me ask you 
something, do you notice flickering on your dekatron? It looks like you are 
using the "pie" type animation, I'm using your kit for another clock and 
opted for the "processing" type because the flickering was very prevalent 
above 30-40 seconds counting, since I assume the neon dot has to dance 
around a lot to light that many positions.

Bravo! I like the wood/gold effect...the use of the orange LED is an
interesting one...didn't want to keep the neon theme there?

My latest clock:



I decided to stick it in this thread, as opposed to creating a new one, 
because of some of the similarities between this clock, and the one 
initiating this thread,


Both use smaller nixies for the *seconds*, and both use a unique *colon*. 
In the case, of the original, the *seconds* nixies is/are(?) the *colon*. 
Not in the case of my clock. In mine the hours and minutes are IN-18s, and 
the seconds are much smaller Burroughs B5991 tubes. My colon is a 1/4" 
acrylic rod, with two rings roughened up on it, so that the light emits at 
those rings, forming the colon. The light comes from an orange LED at its 
base. The clock circuit is my standard uC clock kit, with the only real 
modification being the one to power an LED instead of a neon bulb.


Also, it was just a coincidence, on the common themes, between these two 
clocks. I was already pretty far along in the construction of my clock when 
the OP posted his.

Nice touch using the IN-17s that way, makes for interesting visuals!
