Nixie-based tube clocks

B7971 Six Digit Nixie Clock has a new article up on "Modular" Nixie clock.  All I have to say is that this thing is amazing.  It is a direct drive, six digit B7971 nixie clock with little neon light colon indicators.  Other features worth noting: user input is via a rotary encoder, the brightness of the display is adjusted automatically based on ambient light, and there are several fonts to choose from.  Carl Ott of New York designed the electronics and wrote the software.  Michael had the PCB’s fabricated and assembeled the clock.

Be sure to check out Michael's site - he has several build photos worth looking at.




Okay, folks, this is the moment you were waiting for.  I just got word from Jürgen that the remaining pieces of the enclosure are now in stock and ready for sale.  (Actually, he told me a few hours ago but I was at work....)

Please Help! is working on an updated Manuela design and this new clock will allow the user to select from a variety of top-view tubes.  Jürgen has been working hard on the design and he has a question for the community.  One of the options is a set of six SIEMENS red coated nixie tubes.  Alternatively, Jürgen can coat much cheaper IN-12 tubes and achieve a similar look.  Which option do you prefer:
