Good job!!! I may use this idea to run off varmints. I am going to have to study motion detectors to make it work.

Adding a cap on the output to speaker will save the 555 cause it’ll get hot. Idk why but I found out to always couple a cap before speaker lol

Thanks for doing an audio demo. I had not thought about maxing out the 555 by driving the speaker directly ... TBH I have had no issues doing that but I am still a newb. Any thoughts on building the Atari Punk Console with a 556 next? 😂
