Night Vision Goggles

Well this is my first non-robot post to the blog. Tho you can consider it as a robotic project if you think that it is a device replacing a couple of human light sensor with an electronically augmented version. The goggles are mostly made of scrap material. It includes an IR sensitive small security camera, a couple of video glasses and some high-power infrared led. The rest of the goggles are from parts extracted from other broken electronic devices, including the box (which used to be the back cover of my old printer).
The working principle is simple, it uses IR lighting, which can’t be seen by naked eye, but can be seen with an IR sensitive camera. The camera projects the image to the video glasses and the result is being able to see even in complete darkness.
I’ve seen a couple of try on this subject on web, people made night vision scopes by using broken camera modules. Tho they were only providing image for a single eye, while this version is providing the image to the both eyes. Construction may be a little more expensive, but it is definitely worth it.

The purple light coming out from the leds is not visible to naked eye.
