Professional models of night vision goggles or night vision devices (NVDs) can be extremely expensive because manufacturing companies don’t realize the utility of NVDs for civilians and non-professionals. Expensive night vision goggles are most commonly used by police and military forces. However, scouts, campers, and hunters may also require these devices for safety and convenience in the wilderness. If you’re wondering how to make night vision goggles, then there are some easy and simple ways you can create fully functional night vision goggles.

For those who are crafty and enjoy creating innovative devices in their garage, these DIY night vision goggles can be a fun project. They use the same technology used in affordable NVD models. Even though they’re made for recreational use, the satisfaction that comes from making your own NVDs Trusted Source Night-vision device - Wikipedia A night-vision device (NVD), also known as night optical/observation device (NOD) and night-vision goggles (NVG), is an optoelectronic device that allows images to be produced in levels of light approaching total darkness. en.wikipedia.org will be unmatched store-bought alternatives. It is incredibly inconvenient for non-professionals to buy pricey NVDs. Therefore, we will teach you how to make your own night vision goggles!

Hardware

How to Make Night Vision Goggles?You’ll need some important supplies and devices to make night vision goggles:

  1. Analog Camera: You need a quality camera that is highly sensitive to dim lighting and movement. The type of camera you use in this hardware is the most important because it will ultimately determine the functionality and performance of your night vision goggles.
  2. Mini LCD with Analog Video Input: This will enable your goggles to have features like a rearview display.
  3. IR Diodes or Flashlight: This is important for illumination because the camera will be blind in the dark. We prefer using diodes because flashlights can add considerable extra weight to your goggles.
  4. Power Source: You need batteries for powering the digital devices. The most preferred option is 4×3.7 lithium-ion batteries.
  5. Step-Down Voltage Converter: This is necessary for voltage regulation, so the batteries don’t supply excessive power to the camera and LCD.
  6. Switches: You need two separate switches for power and IR LED diodes.
  7. VR Goggles: You can buy cheap VR goggles if you are on a budget. These will hold all the items together and securely provide a frame for your NVD. Some people may also find it convenient to create night vision monoculars because they are comparatively lighter and easy to use!

Power Supply

How to Make Night Vision Goggles?Now we need to secure the connections to enable a reliable power supply. This is a fairly easy step, and we learned it in middle school physics. You simply need to connect the lithium-ion batteries to the step-down voltage converter and adjust the power supply according to the voltage required by your camera and LCD.

Most probably, you will have to adjust the voltage output to about 12V.

You are now ready to install all your hardware together inside the goggles.

Connect the WiresHow to Make Night Vision Goggles?

  1. Now it is time to connect the wires. You will first have to connect the camera to the display. This task requires an adapter for better execution since the camera and LCD can both have RCA connectors that are difficult to pair without an adapter.
  2. Connect both the camera and LCD to your power supply that you prepared by connecting the batteries and the step-down voltage converter.
  3. It is advised that you use one line of the main switch to connect these items and save the second switch for the IR diode connection.

IR Diodes InstallationHow to Make Night Vision Goggles?

  1. Once the overall model of your night vision goggles is ready, it is time to connect the IR diodes to the power supply.
  2. Diodes must be connected to the batteries in series one by one, along with a 5ohm/5W resistor that will reduce current and protect against short circuits.
  3. Connect the diodes to the switch. Remember the second line of the switch that you saved earlier? Connect the IR diodes to that switch because keeping the camera and LCD on a separate switch is much safer.
  4. Your IR diode is successfully mounted. The separate IR diode switch will allow you to turn the diode on and off without turning off the camera and display.
The diodes also do not require a voltage converter and can be hooked to the same batteries as the camera and LCD, saving your batteries from losing power through the voltage converter.

Test It!

Congratulations! Your DIY night vision goggles are complete. It is time to take them out for a test run and see how well of a job you have done! You can test the range and clarity of your night vision goggles once it is dark enough outside. If you did everything correctly, then you should see targets from approximately a 15m distance.

Final thoughts

Making your own night vision goggles is not only convenient but also a fun task to take on! You are not required to spend thousands of dollars on professional models of night vision goggles, neither do you need expensive supplies for your own DIY NVDs. Still, some of you might be interested in checking professional-grade tools. For instance, the ATN PVS14-3 offers exceptional image clarity every time.

We understand the utility of night vision for safety purposes, and one thing about home security is that you cannot always sit by the window with your night vision goggles on. Therefore, you can also consider buying a night vision camera that can be installed with your home security system or be used when out on an adventure in the dark!

We hope you found this guide useful and your DIY night vision goggles were a success. Let us know how your night vision goggles turned out, and feel free to provide us with any useful tips and suggestions you may have!
