A client came to me to set up the project that is in the book Bionics for the Evil Genius on page 66 "Panic Generator". It's an old project if you have another more current, modern one and if it's possible to add USB inputs, P2 plug, P10 socket for microphone and that has the option to record the sounds it would be of great value. You can even modify the project in this book. Or perhaps some other electronics book or magazine that has this project
