I would like to make an EL wire (electroluminescent wire) inverter because I can't seem to find a commercial inverter that can drive the right length of wire from the batteries I would like to use: all inverters that run on AA/AAA that I can find can only officially drive up to 9ft or so.
According to the Wikipedia article, EL wire runs on 90-120 volts at about 1000 Hz. There are some relay-based designs for EL Wire inverters out there, and I have seen some transformer-based designs, but it seems like there have to be a better way. There is also the SP4425 inverter driver chip, but it is hard to get in the US. Any suggestions on how to go about this? I am looking to drive between 9 and 15 feet of wire, but I was assuming [incorrectly?] that there is a general solution.
EDIT: I would also like to know what it means when we say that inverter A can drive 3 feet of EL wire, and inverter B can drive 30 feet. Is the difference how much current an inverter can source?
