biNixie clock, 95% complete

[Paolo Cravero]

Hi.

Yesterday Michail said "It's kind of like having a 4 tube nixie clock.  Little boring.  Need 6 tubes.  :)". Well, I went the other way around and almost completed a 2 tube nixie clock :)

"Action" is necessary with two tubes if you want to display all time information. Even more if date is required as well. Preview video: https://www.youtube.com/watch?v=DykPl6_dmRE

The circuit is 95% complete: it misses a couple of buttons to manually adjust the time. I should then find a suitable wooden box. Speaking of buttons, I am looking for suggestions to keep the 60's look since I hit Earth slightly later than that "era".

Circuit details:

- Two Burroughs B5092 on correct sockets
- Arduino clone with my own firmware (will be public)

- RTC DS1307 with battery backup

- lumos.sk HV PSU

- K155DI BCD decoder/drivers

My clock feels like a bridge across cold war powers time warped to 2015 :)

Nice,

 

I like it.

 

Interested in seeing the sketch/program.

 

Suggestion:  Since you're using the RTC, why even have visible buttons?  They would almost never be used.  Just put them on the bottom or back of the box where the power cable goes in.

The sketch used for the video is here https://github.com/jh1995/biNixieClock . I know few optimizations are possible. Please share back your code changes.

The hidden buttons idea is excellent, thank you. I will only need a flip switch, or implement the PIR movement sensor as I read somewhere.

Do Nixie age and degrade if HV is applied to the anode but all symbols are off, for 95% of the time? I should switch off the HV PSU to save power, but that's at the bottom of the to-do list.
