New Invention - Electric Emergency Siren Sound (4K)

PCBs from $0 (Free Setup, Free Stencil) :


The project is about making electric emergency service siren sound effect circuit. This circuit can be operated at only DC-12v power supply circuit. To make this circuit, we are using transistor, capacitor, resistor, PF, power supply and sound speaker.

You can use this circuit for ambulance siren, fire siren, police siren and emergency service siren also.


I'm very professional with my business. Some experiments and ideas can be dangerous. You should not take risks and damage yourself and the environment.

Warning :
This project is for education and demonstration purposes only. Some ideas present jeopardy and risk. For that, you should be understood before attempting.
