I'm experimenting with electro vibrations. This principle is about simulating textures using low current electricity on an insulated conductive surface (see Wikipedia: http://en.wikipedia.org/wiki/Electrovibration).
I've started to use some EL-wire IC's to create a AC signal from a DC powersupply since i need a high voltage AC signal (max 115 vpp). With the IC's i got some results but i'd like to have more freedom in the output (the ic gives a fixed voltage and frequency).
Actually what i'm looking for is a high voltage, low current signal generator circuit. 80-115 Vpp (AC) and 80-400 HZ. I'd like to control it with arduino. So ideally it would be a way to amplify and convert the 0-5 DC signal to a 80-115Vpp AC signal.
What's the best way to do this?
