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?

My first guess would be an old bike 'dynamo' - the type that is friction
driven from the tyre wall.

Or a hub dynamo.
