To be completely honest, I did NOT look at Dino’s circuit or video before I started my schematic. We both ended up with 100uF caps in series with the speaker, but that’s about the only similarity. It just goes to show the 555 is a very versatile chip to have in stock at your lab.

Well I just want to say, thank you Dino for motivating me to complete this project! If I didn’t see your Altoids Screamer project today I might not have every taken this idea out of my head. It’s loud and annoying and so very very perfect
