DIY Police LED With PCBWAY

Hi

Delta hack today will show how to assemble a police flasher using simple electronic components based on a printed circuit board.

At first you can see video instuction

Scheme and board template you can download here. Let's go.

Image shows a diagram of the device.

First we need a PCB. This time we use the PCBWAY service.

Free 10 pcs for New Members: https://www.pcbway.com/

We upload the file with our project to the site and after 5 days we get the boards we need.

On the image you can see all the names and the number of components that we will need for the project.

First of all, I decided to solder the LEDs.

It is very important to observe the polarity of the diodes. This is clearly visible on your screens.

Observe the cleanness of all components and install them in the right way. I recommend buying 1-2 units more in order to replace if they fail.

At the last stage, solder the 9v battery socket.

The device is ready! Great reason to scare the naughty neighbors by the police. Using Potentioneter - you can change the frequency of flashing bulbs.

We decided to use this device in the car. Be careful - this is illegal. But we did not go on a public road.

Have fun with Delta Hack and Subscribe to the channel!
