Variable voltage is easy (basic tranformer theory)... Varilble Frequency is near impossible: You have to control the generating source to control the frequecy, therefore you've got to take the source energy, convert to DC and then use that to drive a DC motor to convert back to a variable frequency....
I think.

There are various options depending on what output voltage you need. One of the simplest ways is to plug an audio amplifier (e.g. your stereo) in and have it amplify the tone from an 800Hz oscillator to drive your circuit. How to get 800Hz? Use your tape recorder to record the F or G above middle A on a piano to generate this--using a continuous loop tape, and you're there.

I can't help...but I'm curious as to what you're trying to do.
Me too. What are you trying to do?

These guys look to be willing to just sell you a DC->HF AC converter for 10-30 bucks.
Combine that with an easily acquired 12VDC supply, and there you go.
I totally wouldn't try to build that yourself. Not worth it, at these prices.

What Robert said makes sense, but ideally you would need some type of variable voltage, variable frequency power inverter. That would basically take the 120V/60Hz AC line, convert it to DC, then convert it back to AC at whatever voltage and frequency you want.

I just take it to the village and have the shaman do that kind of thing. It seems to involve a bunch of yelling and stuff.
Does that help?

A transformer works like this (theory only no practical adivice.)
You have two sets of windings. Let's say the power in side has 6 wraps. If the power out side has 12 that will double the voltage.
That's about what I know and it may even be backwards.

This is all good stuff! Thanks!
I have X10 equipment all through my house. It's capable of being dimmed. I am wanting to try this EL wire as interior lighting. It uses VERY little power and might be enough to light my hallway, but it can at least be used to light inside my closets. In some cases I may be able to replace incandescent bulbs... thereby lowering my electricity consumption... In other cases it will just look really COOL!!!!
I also want to use some of it around my garage door... I want to make a blue glow effect around the door... to make it look a little like the shuttle bay on the NCC1701-D... ;)

Why don't you just get a low voltage dc power supply and use white light and blue light leds?
It's safer with low voltage, the leds are very efficient compared to even flourescent, last for years and they don't put out any heat. That's the only lights I have here on the beach, haven't replaced one in 6 years. My system is solar here, no electric service available so I do everything I can to save. 10 Watts of LED light is about the equivalent of 150 watts of incandescent.
