admin Here is an how-to make an night vision setup with infrared for basically any application, in this instance it was used on a air rifle.
Note the ebay links are just so you get the idea of what to get
Things you need:
- Infrared laser module with adjustable lens (Over 200mw needed for brightness) Ebay link
- LCD screen + Infrared camera with interchangeable lens (lens required if used on rifle scope) CCTV site Link
- 16mm PCB lens (see above if required)
- Laser module driver, buy or build one. (will post below instructions to build your own) Ebay link
- Battery or power source. (I used rc plane battery) Ebay link
WARNING: High power lasers is very dangerous to your eyes, and safety goggles should be used at all times
Laser driver
Parts used:
- 6X 100OHM resistors
- 1X LM 2937 fixed voltage regulator (3.3v)
- 2X 16mF Capacitor
- Project board to solder on components
Here is the diagram
Camera
The camera can be used any way you want, or mounted on what ever for night vision, but for rifle scope application, it needs an 16mm lens, other wise you will see the inside of your scope, instead of the whole picture like you would looking down the scope normally.
Simply open up camera, and turn the lens out (requires some force, depends on camera I guess) and replace with new one.
Where to put it all
I used an enclosed plastic ABS container to house all the loose ends, wires, battery, driver , etc.
End result
Note, I cannot add a picture of it in action due to high contrast on the camera, but here is one you can see something on the photo instead of just white.
