Let's talk about something in the meantime, though.
@CounterRotatingProps: Where did you get that cool avatar? What is it of? I've always wanted to ask but I have never found the proper time to.

RE·avatar, thanks, it's from·an old Star Trek episode - forgot the title - they go back to the late 1920's to find McCoy. He caused the "end of the world as you know it" for the future crew. McCoy jumped backward in time in a drug-accident induced psychotic state and changed the course of history. In that scene, Spock is using vacuum tubes to interface a tricorder to replay·its captured record of history in an effort to figure out what went wrong.· Kirk comes and an sniffs, saying something like "is something burning?" Spock replies "I'm overloading that circuit there." In true Star Trek dramatic fasion,·as they're playing back the tricorder history, just getting to the answer, the power supplies Fry !· (And judging from the size of the tubes, the voltages are probably > 350 VDC - so the sparks and smoke might be not too far off.
And to avoid copywrite issues: that avatar image is posted soley for educational purposes only, the education being: don't overload your circuits or this might result. [noparse]:)[/noparse])

I could almost remember that.
The trekkies rate that episode as one of the very best, if I recall. Ellison's writing is superior for certain.
@mpark --- looks like you'd better edit the subject to the "(no subject star trek subject)" --- subjectively speaking, that is :-P

Now, we can easily get 100v or so for a couple 12AX7's using the charge pump ideas floating around the forum recently. A friend of mine has guitar effects amp using exactly that idea. So the first thing that comes to mind is a Prop with tube audio amplification.
Or conversely use a tube to amplify incoming signals for ADC.
But there must be some more imaginative ideas.
Pushed to the extreme I have a VCR97 scope tube from 1940 something that maybe needs a Prop to generate vector graphic displays signals for it. Vector graphic Asteroids anyone?

Yikes ! that brings back haunting memories... used to repair those in the game arcades. The occasional beer bottle through the screen made for an interesting afternoon's work.

Yes indeed, you Brits have a better handle on English that we Ami's do [noparse]:)[/noparse]) (Give a Brit and an American *five* words to use or not, the Brit will find a use for all five, the Ami only 2 or 3 [noparse]:)[/noparse]
I tutored English in Germany for several years on the side - the locals would always ask me to teach them "English English"

Your line used to be "I'm overloading that circut". I, not watching Star Trek, figured it was a joke and told you that it was funny, and you seem to have changed it right after that. Was it me that made you do this because you then discoverd that non-Star Trek-watchers wouldn't know what you are talking about? I just realized that this might be the case, for anyone who has not seen the show·knows who "Spock" is.
Did someone say something about connecting a Prop to a vaccum tube? You might want to capture a video of this one in case you make a wireing mistake: it would hit YouTube as a big hit. "The Exploding Chip" they would·call it, as it will be the only video of someone accedintly pumping 100V through a Prop (and the fact of people like me liking to watch things explode)
They should really have a forum catagory for·Parallax-lovers to just come and talk in. I'm sure that·they will not be detured by the·tube-interface comment and will transfer this post to the sandbox.

I have a couple of tubes of the type called "magic eye," which was used as a tuning indicator for radio receivers in the tube era. They are visible indicators that go from fully lit to dark based on a 0 to -6 VDC or so bias, which could easily be created with a one transistor charge pump. I've been thinking it would be very cool to hook one of them up and make it into a bandwidth indicator for my internet connection.
Now that is just the kind of idea I was searching for. Brilliant. Could also be CPU load indicator for a PC.
I wanted to make another digital clock using Nixie tubes but the are as rear as hens teeth now.

Besides, they now retail at abou $100 each, and you got them for 10 cents each!!

How about something along the lines of an unread inbox count for your email?

I recieved my first propeller logo sticker yesterday. Everyday I see the intel logo on computers, or AMD, or NVidea, but #$%^ this sticker is huge!!!!!!!!! I guess those projects in altoid tins are just out of luck

I've got one of those on the back of my car. {highly recommended}
It would be cool to get some that were PClogo size. Of course we
might need to pony up a buck or two for them. Last time I priced
"ORRTECH" labels for my shop they were too expensive to make
it worthwhile for a little PC shop.
