DIY night vision device from a smartphone

Hello friends! This not complicated night vision device is really easy to make and anyone can do it. And now I will tell you how to make it. Such a device can see even in complete darkness, and can also take photos or record videos. This device can be assembled in an hour or two; no special skills are required.

Materials you will need:

  • A 12V battery or accumulator (I used 3 4V batteries from a flashlight, connecting them in series).
  • Wires for installation.
  • Switch.
  • Hot melt adhesive.
  • Infrared LEDs 5 pieces. (can be taken from broken TV remotes).
  • Cardboard box.
  • Black paint.
  • Insulating tape.
Tools for work: Pencil, ruler, knife, wire cutters, pliers, soldering iron, hot-melt gun, brush and tester (if available).

Making a simple night vision device

Let's begin. I open and disassemble the cardboard box and make markings on the cardboard: cut 2 rectangles 22.5 cm x 5 cm with a knife, bend each of them 90 degrees, 15 cm from the edge. I ended up with two L-shaped pieces, which I glued together.

I cut and paste the inner partition one cm from the edge, while on one side the partition has a gap of 2 cm.

From the outside, the gap is covered with a lid (glued) made of cardboard measuring 2 cm x 7.5 cm.

A second partition is cut out of cardboard, completely corresponding to the internal dimensions of the case. In this partition, I cut out a rectangle of 4 cm x 3 cm on the side, and in the middle I cut a slot of 0.5 cm x 4 cm.

I cut a round hole on the side of the case for the switch. I paint all the parts with black paint on all sides.

I connect the batteries in series and make a tap for the switch.

I glue the batteries into the case. I solder and screw the switch. I bring out two wires to power the backlight. When the switch is on, they should receive 12 V, when off, the voltage is zero.

I solder infrared ones from old faulty TV remotes LEDs. Every Light-emitting diode I connect through a 270 Ohm resistor and connect them all in parallel.

And I bring out a short wire from them to supply power. I connect the backlight to the backlight power output. I insulate it with electrical tape and insert the backlight into the housing, tuck the wires so that they don’t stick out.

I close the lid. All is ready.

To check the night video device in operation, we take a regular smartphone and insert it from the back under the lid into the inside of the device, on the other side I secure it with an elastic band.

Watch the video

If you don’t understand any aspects of making a night vision device, watch the video for the entire manufacturing process and demonstration.

I recommend assembling such a device with children, the process is not complicated, and the children are delighted. Good luck with your assembly and good mood!

    Such devices must be made with children! Otherwise, young people are buried in their smartphones and don’t do anything with their own hands, but before, everyone made something.

    The idea is interesting. And if LEDs If you solder more, there will probably even be a spotlight!

    I don’t have that many remote controls, what can I replace them with? Maybe something from the phone will do.

    Fedor wrote correctly - Such devices are a must with children. Modern children don't know how to make anything. We need to get used to it.

    NORMAL IR DIODES GLOW RED THEY ARE VISIBLE EVEN IN THE DAY. FROM OTHER LIGHTING THEY ARE ALMOST ZERO.
    SO ISN'T IT EASIER TO JUST TURN ON A FLASHLIGHT ON THE SAME SMARTPHONE FOR FREE ))
