[neonixie-l] Any large tube clock kit recommendations

2016-11-09 Thread Dylan Distasio
Hi folks-

I'm trying to help a friend put together the nicest nixie clock possible
for between $350-500 with tubes.  I'm willing to build it from kit for him,
so through hole (and relatively easy SMD) soldering is fine.  I need some
kind of case, although acrylic is fine and he likes the look of it.  He
loves the Zen clock (who doesn't?!) but doesn't want to spend that much.
I'm basically looking for the biggest tubes possible at that pricepoint
range with some kind of enclosure.  I'm willing to source the tubes
separately but won't have any magic cheap supply for them and will be going
through fleaBay or somewhere readily available so I do need to include the
tube cost in the total price.

Any suggestions welcomed.

Re: [neonixie-l] The Bombe Clock

2016-11-09 Thread gregebert
Absolute work of art.

I hate to be a copycat, but since I'm working on a 7971 clock, adding some 
'enigma rotors' would be an interesting feature. I'd probably have 
something go ka-chunk a few times when a word or phrase is displayed.

Re: [neonixie-l] The Bombe Clock

2016-11-09 Thread Paul Parry
No, the drums don't rotate as per the original. The original has the drums 
index round - I could have done it with stepper motors, but gets noisy. 
These on the clock just turn at variable speed, there is a control panel on 
the side for each drum. However each drum has an embedded Neobendyum magnet 
at the 'A' position, and inside the clock is a hall effect sensor. Some 
very simple logic checks to see if all 4 drums are in exactly the same 
position and when this occurs, there is a mechanical chime inside that 
fires. In practice this means you get a random chime from the clock 3-4 
times in a day. Not as Turing intended but a nice little touch as it 
appears to do something other than just spin the drums round.

That's beautiful! I love the "Cherenkoiv radiation in water" blue shade 
of the LEDs too.


What's the behavior of the drums? Do they permute properly?

Cheers,
Robin.

Hi All,

I thought I would just share my latest clock - the 'Bombe' made as a
tribute to Alan Turing and the work carried out at Bletchley park during
WWII. Has the lovely Dalibor tubes on there, and mechanically 1:1
accurate from the original Bombe. The Welchman Trust, who re-built the
Bombe at Bletchley were kind enough to loan me a set of drawings. The
drums are powered by brushless motors, and it is silent in operation (
unlike the actual Bombe! )
Would like to thank John S. for laying out one of the PCB's and also
Dalibor for making the tubes to go on it.
