Do you have a technical question that doesn't really fit a specific console? Want some general info on electronics, hacking, making cookies, etc? Here's the place to ask! Go nuts.
What do you need it for? Does it need to be a nice sine wave? Does it need to be centered around ground? An H-bridge is usually the way to go, but getting it to a nice sine wave can be pretty difficult.
What I have shown you is reality. What you remember, that is the illusion.

i had to do something like that for my computers water cooling, but i found at the local electronics shop (jaycar in this case) a car adapter that did the trick, it was around 4 watts. and had a very messy square wave output (just wanted to test my new oscilloscope)
Felino: What you should probably do is generate a squarewave, with a 555 or otherwise, and connect that to a transistor which controls the current. Preferably a FET with a low voltage dropout.
I don't have any schematics for it though, sorry.
