Make A Point-and-shoot See Infrared Light

[Daniel Reetz] has caught the Kinect hacking fever. But he needs one important tool for his work; a camera that can see infrared light. This shouldn’t be hard to accomplish, as the sensors in digital cameras are more than capable of this task, but it requires the removal of an infrared filter. In [Daniel’s] case he disassembled a Canon Powershot to get at that filter. There’s a lot packed into those point-and-shoot camera bodies and his teardown images tell that tale. He also ended up with extra parts after putting it back together but that didn’t seem to do any harm.

After the break you can see video that shows the Kinect’s speckled IR grid, which is why he needed IR sensing in the first place. But there’s also some interesting photos at the bottom of his post showing the effect achieved in outdoor photography by removing the filter.

The flash never made it back in the camera. That’d be a perfect place for an IR light source. You’d end up with a night-vision camera that way.

DIY Night Vision Monocle

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.

Things To Hack: Sub 100$ Toy Night Vision, Projector, And Tv Game

projector

Ars Technica writes about three new toys coming out this year: a sub 100$ projector, tv game, and night vision goggles. The projector runs at standard TV resolution, takes standard composite in, and outputs an okay picture. The night vision goggles are monocular but focus both eyes on a single RGB LCD. The goggles uses an array of IR LEDs instead of amplifying ambient light to see in the dark. Lastly, they have a standalone implementation of the arcade game Big Game Hunters. The rifle uses a sensor bar to do the motion tracking and features a 32MB rom to hold the game files.
