And of course, there's always SCA Year 5000 as envisioned at Costume-Con 9.

Wow. Homemade vacuum tubes? Dang, whodathunkit? That's uber cool! Neat seeing how he set up his tools and process to work with the torch. Thanks for sharing this one.

I remember something that was told to me "way back in the day"...

There is a thing called a "flash bomb." It's a type of weapon that destroys solid state electronics. When it all goes down, the only thing left that operates will be devices built with vacuum tubes.

Naturally, I can't validate this claim but it's a fascinating thing to think about nonetheless.

This video was absolutely amazing to watch! Thanks for posting it.

Jovino,

EMP - Electro-Magnetic Pulse - is what you're referring to. All electronics are subject to its effects, even vacuum tubes. The difference though, is that it takes vastly more energy to disable or destroy a vacuum tube than it does an integrated circuit. Vacuum tubes operate at much higher Voltages than IC's and they are designed to withstand vastly greater temperatures. A EMP blast that might cause a vacuum tube set up to be temporarily overloaded would most definitely fry an integrated circuit to the point it was but burnt out useless junk.

The downsides of vacuum tubes is that they draw a vastly greater amount of power to operate and they generate a vastly greater amount of heat as they do. They're also orders of magnitude larger than an equivalent integrated circuit and, aside from being more pulse resistant, tubes are a heckuvalot more fragile than solid state stuff.

Ohhh, thanks for the refresher on this! It's been some time since I though about this and as you can tell I was a bit off. ;)
