[sdiy] Electronics class for kids

[Tom Wiltshire]

A 555 timer and a 4024 counter got me into synth DIY. When I discovered I could feed the LED flashing circuit's output to a loudspeaker and get rapid clicks, I discovered making my own audio for the first time.

I was wondering if anyone could give me any suggestions for cool noise making projects?  I'm not very familiar with synthesizer design, I've been reading up on it a bit and started putting together a simple sawtooth generator, the one with an integrator and a comparator, where the output ramps up until the comparator shorts the integrator's cap and discharges it.  I'm looking for simple circuits like this, I'm not worried about correcting non-linearities or temperature compensation, just noise makers to get the kids interested.
