So I have been wanting to do this video for a while and finally got to making it. Basically it's a flash light with the LEDs taken out and replaced with IR diodes.
If you're unfamiliar with Infrared it's the lights that are in TV remotes. If you want to do a simple test to see what it looks like take out your phone open up the camera and point your camera at a TV remote and start pressing buttons. That's what I used for lights in this flashlight.
Feel free to check it out and like share whatever you want if you like it.
To explain a little more about it this flashlight can't be seen with the naked eye when it's on but if you have a phone or some form of camera you can pick up the light. It's good for taking photo's or if you just want to mess around with it.
