[General] 555 timer audio circuits

[John Kelly]

​Just as a tangential brainstorm: if you your goal is to get kids
interested in electronics/circuits with a simple 555 audio circuit or such,
one interesting thing you could do is have them bring in a toy to modify.
Have them make the circuit that generates noise, blinks lights, etc.​
​ and then add it onto their toy to make it super cool.   :D
