For a class in school I want to generate an AC signal.
The project is modelling a wind turbine. We will probably drive the input using a drill.
I'm going to need about 10 models. I am only wanting to show the very basics. The signal then needs to be processed, that bit I can handle.
Can someone give me a link to a suitable component to produce the ac voltage on ebay?

thanks

Record a sine wave from compuyer prog.. Burn to CD mp3 thingy or
whatever. Use speaker output.
