DIY Night Vision, where four is better than two

Night Vision projects are great, and the hardware available for the fancy is getting better and better. [Just Call Me Koko] The 3D printed enclosure mounted on a helmet shows exactly the same build using four low-light, IR-sensitive cameras, four displays and four lenses. Why four? Well, mounting two cameras and a display in each eye is the easiest way to see a wide field and for bonus points, it certainly looks extra weird.

At its heart, each of the four parts is the same. A Foxeer Night Cat 3 camera is mounted on the front, its output is directly connected to a 2 ″ diagonal NTSC / PAL display, and a DCX (double convex) lens on the back has a diameter of 38 mm with a focal length of 50 mm. Add a printed perimeter, and the result is a monocular night vision display. Do this three more times and arrange them around the eyeballs, and someone can create a night vision system with a panoramic view that probably only takes one A little Being used.

How well does it work? [Just Call Me Koko] Some walk around and try to practice certain goals while wearing them, and conclude that they have almost no clarity of the actual deal (320 × 240 resolution display limits the details), they work fairly well for what they do. Also, the cost of parts is a small fraction of the cost of the actual thing, making it a pretty enjoyable project in the end.

The kind of hardware available to hobbyists today makes this type of night vision project accessible, but there is always a good old high-voltage analog system.
