Roadtripguy's Homebrew Nixie Tube Clock Project 2...

More of one of my Nixie Tube clock projects from inside my secret laboratory... The clock has come a long way since my last "breadboard" video of it. I designed and had made the TTL "clock" board (in front), power supply board (in the back), and the plug in "bus" board (bottom) which ties it all together. The board in the middle is the tube driver board from the other video, which I designed last year.

I had a few problems, but they were minor. Everything is working according to plan.

This clock features 12/24 hour switchable, colons on/off/blink (and they are fired by four independent transistors, so they can be set individually via jumper block). The colons can blink at either 1 Hz, or .5 Hz via jumper pin. The controls (the little board in the front with the switches) are Run/Set, fast set and slow set. I also can zero out the seconds for syncronization. LEDs on the boards are color coded: green = "heartbeat," yellow is 5 volts for the TTL chips, and red is 180 volts to power the Nixie Tubes.

Now I get to design and build the case.. :)

Send me your Email, and I'll send you the 1:37 minutes of your life back then.

Ahahaha! Didn't mean to offend...but I do like your electronics :P

[TheREALroadtripguy]

No offense taken. :)

[faffaflunkie]

Is that all TTL?

[THEtechknight]

those tubes look to be wore out?

[dumyyyyyy]

super frate!  tine-o tot asa!

[ienjoytaffy]

pretty sweet i have to say

[donnyab]

where did u get the valves from ?

[TheREALroadtripguy]

The plugs are readily available in circuit board form. I don't remember exactly who I got them from, but it was on eBay.

How did you get the plugs?

[EulenthalKruemel]

Wow, excellent work. You used eagle to do the schematic, I fugure? How do you get your time signal? I am going for a 1 Hz signal generator which is hooked up to a set of 4017 counters. I'd love to get some input from you on this.

All best

did you use eagle to draw the board???

By seeing your sheet, it looks like eagle...

Nice job impressive looking circuit. What anode current you using there?
