How to make your night vision goggles step by step

• Buy blue or red theatrical gels and a couple of welding goggles whose lenses can be removed, plus a cheap infrared flashlight.
• For tools, you will need a hobby knife or multi-tool, glue and a pinch of luck.
• You can make your own infrared flashlight with eight to twelve high intensity infrared LEDs. For this, too you will need two 3 volt coin batteries.
• Some thin electrical wire, superglue, and a soldering iron.
• Cut two pieces of each colored gel to cover each of the welding goggle lenses.
• Since the lenses must be removable, you can use them as a template for shape and size.
• Glue (outer edge only) the red gel lenses to the outside of the welding glass lenses and then Stick the blue gel to the inner surface.
• Try to line them up as exactly as you can to filter out all the light.
• Put the lenses back into the welding goggles frame.
• If you are making your own IR flashlight, now glue the LEDs to the outer edges of the frames, pointing outward to illuminate the objects you are viewing.
• Stick the batteries to the ear cups of the glasses or wherever it is convenient and connect the LEDs.
• If you have the technical knowledge, add a switch that will allow to turn them on and off with limiting resistance.
• If the image is dim and faint, add another layer of red gel to the outside, more blue gel inside and additional LEDs.

How night vision goggles work

The key component is a dash cam also known as micro camera or spy camera. To be clear, I mean a “low lux” black and white camera (capable of working in very low light, 0.5 lux is good) .Z, not an app where you can take photos with the phone turned off.

Also known as a monochrome camera. These cameras differ in color variety as they do not have an infrared blocking filter on the lens. You can probably guess that this is important.

Because that it is precisely the light that we want to see in the dark. Also, the monochrome type has a very basic 3-wire connection and can be found for as little as $ 10. My favorite online provider is www.esentia.com.

The 3-wire cable is easy as 2 wires are used for a 12 volt supply DC and the latter is used as a composite video output that connects directly to a camcorder to record or record a video.

This configuration alone is capable of producing a clear and removable IR image. A simple test is to point to any remote you have at home that is labeled infrared.

It will pulse in your camera. Infrared light, it is simply a flashlight with a halogen bulb found anywhere for a few dollars.

Optimum would be a halogen bulb because produces the most infrared in white light, But a flashlight with an incandescent bulb will work almost as well and has the advantage of not getting as hot.

Better materials for an IR pass filter

• 5.25 inch floppy disk.

The actual plastic disc inside the square cover.

• 3.5 inch floppy.

Same as above, only the larger 5.25-inch is more practical for cutting out shapes.

• Used cellulose film (developed).

Take a blank photo (no flash) in a dark room for this. And it usually takes several coats for best results.

In turn, night vision goggles can be used as a means of entertainment in activities like paintball or night wars. Therefore, it is essential to know how these tools work.
