This interesting mashup shows it’s easy to make your own night vision goggles. It makes use of just a few parts; the viewfinder from an old camcorder, a low-light security camera module, and a collection of infrared LEDs.
The low-light camera is capable of detecting infrared light, which is invisible to our eyes. If you shine the right IR LEDs on an object, they will cast enough light for the camera to clearly view the objects around you. The camcorder viewfinder is nothing more than a compact way to display what the camera sees. This would be easy to accomplish with a wearable display. It is also beneficial to have a large IR light source so you may consider modifying that giant LED flashlight you’ve been meaning to build so that it operates in the infrared wavelengths.
This project comes from the same source as the Laser Microphone we looked in on last month. Just like that one, there’s plenty of extra information about this build. There’s suggestions for choosing and focusing a light source. This includes using lasers as the source, and binoculars for long-range viewing.
