Learn How to Solder and Build a Police Siren
This project is for advanced students.
This is two projects in one. No one starts out soldering well (I know I didn’t). So, we’re going to start out by just practicing soldering parts onto a PCB that doesn’t do anything. No point in making mistakes on a real project and possibly ruining it.
Once you have the hang of soldering, we’ll make a working siren. Just follow along with the steps in the video. By the way, the siren circuit isn’t that different from the Audible Light Probe. It makes sound in a similar way, and is just wired to make different frequencies take turns by charging capacitors at different rates.
To make this project, you’ll need to get a Police Siren Kit. You’ll also need a soldering iron with a stand and some basic tools (scissors, hot glue gun, drill, wire strippers, pliers, screwdriver). (Need a recommendation for a soldering iron? Click here.)
