Assuming the filament in the tube still works, a low voltage supply with sufficient current would light it up. Add PWM control to the supply, and all sorts of effects are possible. If you keep the brightness down, the filament will last nearly forever.
Well, the box will be antique-looking wood and the panel will be aged (possibly etched) brass -- I'm tending to the pseudo-coal-powered furnace on the right, so thsi will be flickering with reds and oranges and yellows. Also the meter on the left has a black surround, but the "paper" inside (what do you call that -- scale, reticule?) will have different colors (red at one extreme and green at the other ... not sure exactly yet)
@David: ...but the coal furnace would look cool too....maybe have it flickering away with the meter needle moving in sync??
I like that idea -- also when you mess with the switch, things could change a bit and then settle down again -- I'm also planning on adding background sound effects associated with changing switches and stuff...
As a female who first became introduced in engineerig because we had this tiny steam-powered toy factory-and a steampunk fan, I'd have to say this is pretty impressive. But wouldn't a little color be nice??
Max..... "And what do you think about the Phrankly Phenomenal Ultra-Macho Prognostication Engine moniker? Would you change the Ultra-Macho portion?"
In view of Karen's comments about the Inamorata Prognostication Engine, maybe you should get her pronoucements on this? Then again, it's not ultra macho to ask for the womenfolk's opinion? So maybe just do it :-)
Love that old switch Max.....also the idea of antique tubes on top with the rainbow LEDS. Both the coal furnace idea and the CRT are good, not sure which I'd prefer. You could have the CRT displaying lissajous figures or maybe spirograph figures (i have a circuit for that somewhere). The CRT is perhaps more versatile but the coal furnace would look cool too....maybe have it flickering away with the meter needle moving in sync??
