How so? I know it's not UV rated, but I figured I'd give it a layer of epoxy or polyurethane or something to amend that. You're right about the brightness change, which doesn't bother me too much because I'm relying on the LEDs for illumination. Frequency alteration is for the most part a pointless gimmick, but if I can easily implement it inside the sine-wave generator that I'll build anyway I don't see why not. I'll probably go with the white EL wire if I do find a circuit to make the alterable frequency work.

Now when I say I did the maths, I mean I did the maths. From z = X_L+(X_C1+R1)(X_C2+R2)/((X_C1+R1)+(X_C2+R2)) all the way to booty town. The end result gave me exactly the expected frequency (w=1/√(LC)) when the potentiometer was turned all the way to either side, (1mH inductor, 160µF cap gave ~400Hz, 2.8µF cap gave ~3kHz), so I'm assuming that the maths are right. Check it yourself if you feel like a noose isn't quite your speed.

Now this applies for the circuit in pic related, so whether I can get a transistor-driven circuit to use it (each arrangement actually has two different resonance frequencies, the other being in the fractional hertz) is another question entirely. The circuit I just tried wouldn't let me put any kind of resistor in series with the single cap, so I should find a design that does.
