These days big brother is everywhere, with $10 or so worth of items you can build your own invisible "mask" to avoid any kind of identity exposure !

Here's a brief description as to how this works and why it's cool :)
You take a hat that looks good on you, hacking it to be a face mask for any kind of : Hidden, Security, Paparazzi or family member's video camera !
At the same time, when people look at you with the naked eye, they see nothing but you wearing a hat!
Now that's what i call stealth !

You can build it for as low as $10.00
-Materials Needed-
8 or more High Intensity IR LED's = $0.30 each that's $2.40
1 Hat/Cap that looks good on you = $6.00 you may have one all ready
16 Thin wires that i got from a 2 meter long UTP cable = $1.00
1 Electrical Tape = $0.80
-Total Cost = $10.20-

For a better understanding of the project and it's effect i recommend you view video !

Step 1: Step 1: the Hat

The first and most important piece of our project is the hat !

I chose a baseball hat because it's often bigger than your (my) head and all the parts can fit well inside and it won't scratch or hurt my forehead !

Make sure it looks good on you and it can pretty much blend the LED's ... In my case it had some writing on it and it was white so the LED's won't be very eye catching...

Step 2: Step 2: the LED's & Wires

Here we go...

Like i said in the "Intro" you are gonna need : 8 or more Infra Red LED's or (IR LED's) it's best to find high intensity one's, they don't cost much more then regular one's. (pic. 1)

Wiring...

Make sure your wires are long enough around (15cm each) depending on how big your hat is.
Start wiring up the LED's one by one, make sure the wires are secured well to each LED and they won't fall apart. You can even use solder to be extra sure but i didn't , i just rapped the cable around each LED pin then bent the pin horizontally . (pic 2,3)

Step 3: Step 3: Mark & Cut

Mark & Cut

This part is also crucial, you need to pick good spots where you want the LED's to go. If you place them to far apart from each other the light beam won't be strong enough to blind a camera, and if you place them to close they will only hide your face from a certain angle... So you need to think this out and position them well.

Using a marker i first chose the spots .(pic. 1)
I cut a few holes with a pair of small scissors in the front (middle of the hat) and a few on the sides to get a wide beam . (pic. 2)

Step 4: Step : 4 Placing the LED's

Now to put them all together...

To make it easier i turned the hat's inside out.
Take each LED and place it tight in it's hole. (pic. 1)
Make sure each LED is secure and it won't fall out , you can even use glue for extra safety! (pic. 2)

Step 5: Step 5: Secure With Tape & Power Up

Now let's secure and power up...

Like shown in (pic. 1), take all the wires and using electrical tape tie them together, this is easier than any other way to arrange the wires inside the hat.

Make sure you remember each LED's plus and minus wire if you get them wrong you may burn out some LED's or risk some of them not working. I used white wires for each + terminal and color wires for the - terminal so i won't get them wrong later.

In (pic. 2) you can see that i connected a small 9v battery to the wires and secured them on there with electrical tape. You can even add a little on/off switch, but i didn't have one at hand when i made the project...

I placed the 9v battery on the inside back of the hat, then made use of some pocket like material that was in there, to keep it from falling down.

Step 6: Ready for Action !

Now your all done !

Thank you for taking the time to read and maybe (make) this project . (pic 1)

You can view a few pictures of how big brother will see you from now on ! (pic 2,3,4)
