I am a complete beginner in the world of electronics and I am following the amazing book by Charles Platt, Make: Electronics (second edition). I am stuck at Experiment 11, when I need to connect an oscillator to a loudspeaker. The picture shows the circuit I am trying to make. It's an oscillator. It does work with a LED, but not with the loudspeaker. I do hear a very faint click when the capacitor discharge, but no sound. The loudspeaker is a 8ohm as indicated in the book. This is a picture. I know it's not super clear, but consider that the top part works as it should, it's the part with the speaker that possibly has something wrong.
To check that everything was working I also added a LED and made a video (and a switch to control it), here: https://youtu.be/UkEZzxmkfes It shows that the oscillator works ok, but the loudspeaker doesn't.
Am I connecting the loudspeaker the wrong way? Is it possible that the loudspeaker is broken?
More generally, since I am a complete noob, how would I go debugging this / giving people the proper information in order to help them helping me? Thanks!
