See In The Dark, The Simple Way

Night vision googles used to be the exclusive preserve of the military, and then of the well-heeled. Image intensifier tubes were very expensive, and needed high-voltage power supplies to keep them going. Now that we have solid-state infra-red cameras the task of seeing in the dark had become much simpler, and [Alex Zidros] is here to show us just how easy that can be. His night vision goggles take a selection of off-the-shelf parts and a little bit of 3D printing to produce a complete set-up for a fraction of the cost of those night-vision goggles of old.

At its heart is a little NTSC/PAL LCD display in a 3D printed bracket. These used to be a small display of choice, but we see them rarely now because standalone displays and the microcontrollers to drive them have become so much more useful. Driving the display is a video camera with its IR filter removed, and providing illumination is an IR flashlight. In effect it’s a classic analogue CCTV system in miniature, but the most important thing is that it works.

We might have expected a Raspberry Pi Zero and NoIR camera, but it’s difficult to argue with a functioning night vision system. If you want to look at a project with an image intensifier tube though, we’ve covered one of those in the past.
