Mini flashlight


There are times when a small-sized light source is needed or a light source is not at hand at all. This mini flashlight can come to your aid. It can be made in a short period of time from available parts.
Here it is in the picture.


To build it we will need: a 3-volt coin cell battery, super bright Light-emitting diode, battery cassette and button. The battery cassette can be taken from an old computer motherboard; there are buttons in almost any electronic device; for example, I took it from an old printer. Battery and Light-emitting diode You can buy it at any radio store.


Now you need to solder all the parts into one electrical circuit, observing polarity. I won’t give you the diagram, I think you can assemble it yourself without any problems


To add strength to the structure and to give the body of the flashlight, fill it with hot glue.


Our mini flashlight is ready.


It shines great and the battery charge lasts a decent amount of time. If the battery runs out, you can simply replace it.

    Damn, every time I watch it I think, take the stupidity out of the lighter, it’s a hundred times cooler

    Everyone is being clever, but they themselves would at least do something. . . .

    This design has 2 extra parts: a button and a battery compartment; we just stick the battery between the long legs at the right time LED without any soldering (observing polarity) and rejoice!
