I came across a police-style horn circuit a few months ago. Its sound is basically spot-on and I'd love to make it. The problem? No circuit diagram. When contacted, the author has been unresponsive. In the few responses he has given, he seems unwilling to provide the circuit diagram. Hence, the need to reverse engineer it.
The video is:
.
Any help would be appreciated. Based on the resistor color codes I should be able to find out the resistance of the resistors, and I can guess-and-check the capacitors. Does anyone know how to make the colors in a frame more vibrant? The lighting isn't very good in the video.
Any thoughts would be appreciated.
