Hi,
Dont worry about feeling a little funny about it that was a nice diagram. I like the way you added actual pictures of the stuff to the drawing as that brings it to life a little more.
But one thing you dont have to do is do tests that i dont request. When you connect the LED across the AC for example you may have damaged the LED. it may not be apparent right away either. But you did connect it across the 10uf cap and you got it to light, so that's good. That means we at least have some signal getting to the lower transistor base.
What are the actual part numbers of the transistors?
BTW how bright is the LED that was originally always lit up (the one connected to the battery)?
Next, short out the lower transistor collector to emitter and see what happens to the LED that is already in the circuit (no need to connect another LED yet).
Just so you know, we are now in the troubleshooting mode to find out what exactly is stopping the circuit from working as it should.
Also, the two smaller capacitors help to isolate the wall wart from the detector circuit so that connecting it to the battery doesnt hurt anything. There's no short for DC.
