So, any simple/single transister or darlington/minimum parts type solutions...that would fit in a AA battery compartment?

It is almost like the circuit designed by Colin.I made this with parts that were laying on my work table in less than five minutes without doing any math. And with two simple BC547Cs.

The first transistor is turned off but heat will turn it on and if you scream into the mic or hit it with a hammer. The 470uf capacitor is 1000 times too big.
I didn't look. I have many more posts on the other electronics chat sites I visit every day.I can understand how audioguru can get a post count in the 18K range!
I used a soldering gun to scorch electronic parts when I was 12 years old. It soldered things very poorly. Then I got a cheap soldering iron that also got way too hot. Then I got the Weller temperature controlled soldering iron that solders and unsolders perfectly, is 44 years old and it still works perfectly. It is still manufactured and sold today.Bought myself a new soldering gun yesterday (and a desoldering gun for "scrounging" parts from the massive amount of old stuff that doesn't work that I never throw away)
