Digital Night Vision Goggles

Intro: Digital Night Vision Goggles

This project demonstrates that with a low budget, you can make a monocular or binocular pair of digital NVGs. This pair is based on the BPNVG project. It uses an Foxeer Micro Night Cat 3 IR sensible camera and an Adafruit NTSC/PAL 2" display. This pair can be used on helmet mounts with a Wilcox L4G24 mount.

STEP 1: Mechanical Model

I made this model in Fusion 360, and the models are either made by me(Adafruit Display, Eyeguard), McMaster-Carr components, or from GrabCAD. The Eyeguard has been posted on GrabCAD. The model itself is 3D printed.

The goggles can be mounted on a standard NVG mounting plate with a Wilcox L4G24 mount.

STEP 2: Electrical Scheme

This scheme is very simple. I added a 14N001 Diode for reverse voltage protection. Signal from the display is a yellow wire, and the wire for the camera is white. Be aware not to connect white to white, as it won't work.

The working current is 315mAh for 12V, so a boost converter with an 2200mAh 18650 battery would last you approximately 2 hours.

STEP 3: Post Finishes

I applied glue to the wires sticking out of the enclosure, to make it resistant to water. A NATO green paint is sprayed on the body to fill the crevices of the 3d printed parts. The protection caps (Militech Logo) can be omitted, but I recommend screwing them when not using it.

Stay tuned for the helmet mountable battery pack.

Interesting project, a short video would be great, how it works, etc.

I will upload a video of how this works after replacing the fake camera.
