In this video tutorial you will learn how to make a pair of high tech night vision sunglasses. You will first need a pair of 100% clear sunglasses with nothing but UV protection. Then two sheets of theatrical photo gels, one congo blue and one primary red. Using the gasses as a template, outline the lens shape and gently cut out one pair of each gel. Secure the red gels first using glue, and then apply the blue gels over the red ones. Now you're going to need 8 high intensity infrared LEDs. Solder two pairs of three LEDs each in a series. Glue the LEDs on both sides of the frame. Cut the wire around 5cm from the LEDs and secure with electrical tape. Using one 3-volt button cell battery on each side, complete the circuit leaving the plus wire on both sides not connected to the battery. You can later just slip it under the electrical tape to start the LEDs. Now, you can see in the dark, without others seeing you see them. As the gel allows you to view the infrared light generated by the LEDs invisible to others.
