So I'm interested in making an el-wire costume using my arduino for halloween. Made a case for it for another project so not really worried about it breaking which is designed to use a 3.7V li-po cell phone battery with 3500 mAh. el-wire only needs 20 mA/hr-m so I'm sure this will be plenty to last me the whole night.
My issue with it is el wire needs 100 V AC with a frequency between 60 Hz and 2000 Hz. Other than simply switching a relay I haven't worked with AC before so inverters are a bit of a mystery to me. I've seen people steal them from disposable camera's on youtube but anyone able to explain to me what part I should use and why? Also I'm interested in messing with the frequency if possible, changing the frequency apparently has more of an effect on the brightness then voltage does.
I've also heard some people talking about using N-Mosfets to do this, but I don't understand how that works in the least. I always have thought as N-mosfets as voltage switches so unless I magically already have a 100V AC source from some place else I don't see how it would do the job.
