The Police Launch is a Krick kit which I am currently building. it is a really nice project but, as usual, I just have to add things.
The project is to make the blue light flash. The video shows the three stages of prototyping. The first is the circuit built on a Breadboard. The second part is the actual circuit reduced in size ready to hide inside the boat. The third part is the LED fitted in the incorrect position to show how effective it will be.
I have added a trimmer pot to the circuit so that I can select a suitable frequency that looks right at a later date.
Thanks to Doug for his help to get started and give me some hints about how the circuit works.🤓😊
