DIY headlamp

In this article I will tell you how to make a headlamp. do it yourself. For the manufacture of this lamp, you will need a minimum of parts that everyone will have in stock, and if not, then they are not very expensive and are sold in any radio or hardware stores!

List of required items

1. Plastic bottle cap
   
2. 3 LEDs
   
3. Hallmarks for crown
   
4. Battery or battery Crohn
   
5. Button for radio equipment
   
6. Elastic rubber-rubber strap
   
7. Hot glue and soldering iron
   

Lantern assembly

Take the cap from the plastic bottle and make holes for the LEDs in it, you can do this with a thin drill or be sharp with anything, such as an awl.

Now you need to insert the LEDs in these holes in series, so that the plus would be about the minus and so on.

Now we take the pliers and on the reverse side we twist the legs with an LED, plus and minus, and minus the third LED with the plus of the second, in general, sequentially, then solder the legs and bite off the excess.

Then we take the stigma from the crown and solder the wires from it to the free antennae of the LEDs, plus to plus, minus to minus.

We take the button, bite in half one of the wires of the hallmark for the crown and solder the button into the section of this wire. If in the end the wire with the button is too short, extend the wires, well, in principle, the standard length should be enough.

Next, take the crown and connect everything to it. Be sure to check the circuit for operability, for this, press the button, if the LEDs light up, then everything is in order and you can assemble the structure further, if they do not light up, then check whether you have assembled the LEDs correctly.

Using hot glue, glue the button to the crown.

Using the blade, make a small groove in the cover in order to lay the wires in it. Fill the inside with hot glue and glue it to the crown as shown in the photo below.


Now we need a fabric strap and glue both ends to the crown using hot glue.

As a result, we should get the design as in the photo below.

The headlamp is ready.Please note that the strap must be taken with adjustment so that you can easily select the required length. That's all, this flashlight is small and takes up little space. For the crown, you can use the battery so that it can be recharged from time to time.


Thanks for attention!
