Dub Siren Demo - 555 Timer Project

This is my 2nd go at building a dub siren. This version users a custom PCB that I designed based on the 555 timer and 741 op amp. I've also included a reverb and echo and audio amp modules, all powered from a mobile battery. The case is an old intercom In found in the dump. This is a short demo video of the sounds that the dub siren can make. I've also published a longer version of the build which can be found in the link below. I've also published a step by step build guide on my Instructables page https://www.instructables.com/id/Dub-... The schematic, board and gerber files for the dub siren can be found in the link below. https://drive.google.com/drive/folder...
