The increasing use of surveillance cameras for security reasons increases the possibility that, when you show yourself in public, you will be recorded and observed. While part of the population say they feel safer knowing they are being controlled, other people do not tolerate the "Big Brother" atmosphere created by this vigilance system. By inserting a set of infrared LED bulbs into a simple hat you can prevent any camera - be it hidden, surveillance, or even personal - from recording your face. To do this, follow these simple instructions.
Steps
Step 1. Connect the LEDs to the wires
Make sure the strands are long enough (about 6 inches each) for the size of the hat. Connect the LEDs one by one, paying attention to polarity (it may be helpful to assign a different colored wire to each pole: for example, white wire for the positive pole and black for the negative pole). Attach the cables to the LEDs so they don't come off no matter what happens. If you want you can stagnate the connections, but I don't think it will be necessary.
Step 2. Prepare the hat
The position of the LEDs on the cap is the crucial part of the operation, since you have to insert them in a place where they are not noticeable but, at the same time, are not too hidden. If you mount them too far from each other, the light will not be strong enough to blind the lens; but if you stick them too close, your face will only be invisible from certain angles. It is therefore important to plan their location carefully. Using a felt-tip pen, mark the points where the LEDs will be housed on the fabric of the hat; then, with a pair of scissors, cut holes in both the front and side of the hat.
Step 3. Place the LEDs
Turn your hat upside down. Take each LED and insert it firmly into a hole. To ensure greater stability, fix the LEDs to the fabric with a drop of glue; however, be careful not to cover the bulbs of the bulbs and concentrate on locking the wires in place. Use hot glue for this. Once finished, straighten the hat.
Step 4. Immobilize the threads with tape
Tie the wires in a bundle using electrician's tape and secure them inside the hat.
Step 5. Connect an energy source
Connect the wires to a 9 volt battery and secure them with electrician's tape (here it will be useful to have used wires of two different colors, since in the blink of an eye you will know which wires to associate with each pole of the battery). You can even mount a switch to turn the lights on and off. In this example, the battery is positioned inside the back of the hat.
Step 6. Finished
Advice
- Since infrared light is invisible to the naked eye, you will need to test the operation of the system using your video camera.
- Since the light source is located at the top of your head, it is possible that portions of your face will remain visible. By strategically placing LEDs inside the shirt collar and / or wearing ad hoc modified LED earrings or earphones, you will implement the effectiveness of the light mask.
Warnings
- The effect is similar to shooting a bright light in someone's face - except that closed-circuit cameras can't blink. You have to be able to turn your head towards the camera at the right angle and hold it.
- This gimmick works best in low light conditions; in broad daylight or in very bright environments, the intensity of the LEDs will be dampened and will less blind the room.
