I picked up some 16x2 lcd displays cheap. They have el backlighting. What kind of circuit do I need to pwr the el backlights? Are there any packaged pwr supplies units that may be available cheap? Say for 5v, 9v, or 12v inputs?

December 2004 issue of Nuts & Volts has exactly the circuit you need (page
22). It may still be on shelves in your local bookstore. The online versionBe careful with packaged voltage inverters. Most cheap ones I saw are DC-to-DC for miniature fluorescent tubes whereas EL panel needs AC.
