  1. Hi All

    I am pretty green so please bear with me. 

    I am doing a project/experiment/goofing around with solar-powered sound making.  I have been able to power a small store-bought 5V buzzer with some photovoltaic cells and I am very happy about that.  What I want though is a whole bunch of small sound making "things" and there are only so many different kinds of pre-existing buzzers out there.  The idea is for these things to be scattered about a room so that as the sun moves during the day, the room “sounds” different, depending on which things are getting sunlight.  I'm wondering if buzzers are easy to make, then I could make my own with different properties that would sound different.  I'm also wondering what other things make a noise when a weak electric current runs through it.  The more pleasant the noise the better but if all I can do is make an annoying buzz, that'll have to do. 

    Thanks,
    sarah
