Diy night vision devices are easy to do and they only require cheap materials. So whether you need a pair of night vision goggles or night vision flashlight, you can definitely make them even without the supervision of professionals. There may be many complicated instructions online but you don’t have to deal with them. There are easy ways of making your own device, you just need to know the basic theory on how to make night vision devices and how they work.

The first thing you need to know is that white light can impair your night vision. Infrared light is the one you need in order for you to see in the dark. Notice that when you are driving, the car in high beam will suddenly blind you. This is because your eyes easily adjust to white light making your night vision hard to achieve. Usually, it takes 20 minutes for people to adjust their eyes to night vision. Infrared light makes it possible for your eyes to adjust in the dark and at the same time see the things around you.

Red does not impair your night vision that is why most of the night vision devices use red light. In doing your own diy night vision device, you will mostly use red plastic wrap so that the light that will be emitted will be infrared. There are several night vision devices that you can do on your own like night vision flashlight, goggles, and cameras. And they are pretty simple to do.

The easiest device that you can do is the night vision flashlight. All you need to do is to cover the end where the bulb is located with red plastic wrap. Then you will have your own night vision flashlight. Just make sure that the plastic wrap is thick enough so your night vision will be preserved.

Diy night vision goggles can also be made in your own home. You just have to have a pair of goggles and replace the lens with red and blue colored gels. LED lights should be placed at the side and wired to a low-voltage battery. The light that will be emitted should pass through the colored gels to produce infrared light.

Lastly, diy night vision cameras can be made by replacing the glass in front of the CCD with a used photographic film. This should be paired with an infrared flashlight so that you can see the things inside the room.
