These things probably consume just a couple of mAh so power consumption would be way less than an incandescent lightbulb, nothing to be worried about. That kit also comes with a transformer for 110 and 220, which is awesome.

Filter capacitors, resistors, some potentiometers for control. What is this used for, just straight audio amplification, or something guitar related?

Sorry I should have given a more direct link to the kit.

Pretty damn good deal for an awesome clock kit like that, and I'm assuming the avr is pre programmed.

Semi related schematic, found it on my first day on /diy/. Already had one designed, but this is cool.

Nice 12at7 preamp tubes there.. I built a simplified circuit like that, but with a 12ax7 and a solid state main gain stage for a guitar amp.

pic unrelated, just some nixies. (B-5025)

Ordering a couple of these to play with this week, super cheap and easy to wire up. If I decide to control it with an AVR I'll have to use PWM or something.

VFD's typically run in the 30v range I believe, making it easier to supply the power. (Voltage doubler or tripler could do it for you)

Anyway, these things are pretty cool, maybe I'll experiment once I'm finished with nixie stuff.

It seems like its pretty hard to find VFD tubes that don't have a backing inside, its just the frame of the character like in the pic.

Anyone up for another tube/vintage thread?

Post some cool stuff, tonight its VFD's for me.

I'm off to bed, I'll probably start another one of these threads in a few days, I'm a regular here now.

It was 18 gauge wire, just a scrap I had on my desk. The wire flew off somewhere, it probably melted the insulation. My hand is sore, but I think thats just from my reaction..

My multimeter was out of batteries, and I didn't think there would be negligible power stored. The more you know..

For sure. I have a couple 1.7F electrolytic capacitors sitting next to my bed, they haven't been used in probably more than 10 years, but they serve a nice reminder. You could easily fit a coke can inside of one of these..

Pic is similar to what I have.

Right, because those are vacuum tubes, unlike stuff like nixies which are filled with neon, and lightbulbs that are filled with whatever. (argon?)
