EL panel and inverters are interesting material, but rather hard to control since it involves inverters with AC current. There are some nice tutorials on how to control AC side with triac or EL sequencer at sparkfun, buildr.. so on. But I always had a bit of problem when I want to fade them slowly, or when I use many EL panels on at the same time. (inverter that connects to EL sequencer has limitation on the size and number of EL panels it can light up at the same time)
