i love weird clocks ;-)

numitrons are also cool, you can drive them directly from 5V ttl or ucontroller io. you get the tube look without a lot of hassle, and there not as over-exposed as nixies.

i remember when these were used in gas pumps, they might have been the first digital displays for that use.

12V or no, that’s one cat away from a small fire.

chango… dont know much about electricity do you…

Unless the cat is soaked in gasoline and you can get the thing to spark there is zero chance of fire if tipped over or even beat with a hammer.

sometimes the safety mindedness of hackers surprises me ;-) i’m sure you unplug all your wallwarts before disconnecting them in case the end touches something metal.

this thing is no danger. but perhaps that is part of it’s appeal.

i really dig the structural circuit design.

@farthead

You never know, maybe highly charged gasoline soaked felines are common at chango’s pad. Maybe it keeps the flees off?

while we’re on the funky display tube topic, a great resource for nixies, vfd’s, numitrons, crt’s etc is spehere research in canada. a lot of interesting stuff to be had there.

I thought you said Open FLAME clock. Now that would have been impressive. But this is cool too. I dig the Numitron tubes. It needs a protective Plexiglas case. I can just see some little kid grabbing the frame or some ones beer hitting this thing.

We did a similar project this past holiday season:
http://www.instructables.com/id/101_Led_Wreath/

It’s a wreath is made out of 101 LEDs and two pieces of wire, with no other components. It can run on a 9-volt battery.

The only way to improve this would be to have a spider live in it.

this looks like a fun project i may have to do this. its a good way of displaying how a clock works.for those of you that think this things a fire hazard you aught be shot!. its low voltage harmless! pussys.
