Make Your Own Simple, Sleeping Bag Sized Faraday Cage in 30 Minutes

This step by step guide will help you construct a small tent or large sleeping bag sized faraday cage made of wire mesh, which is also portable. Efforts have been made to fold away all prickly ends so that entering and exiting or handling the cage is safe. The cage will suffice in shielding you from the worst of microwave attacks during the vulnerable moment of sleep. It should be temporary, designed to afford you protection when, for some reason, you are unable to construct room-wide shielding, or when you spend time away from a protected area. Follow the instructions carefully in order to ensure that the cage works and is safe to spend time in.

Getting Started
Measure your height. Add 30 cm to your height and purchase at least twice the total length of the result, plus 50 cm, of wire mesh. For example, if you are 170 cm tall, then you will need 450 cm of mesh to construct a single layer faraday cage: (170 + 30) * 2 = 400 + 50 = 450.
At least a meter of hard wire or an office stapler.
Working gloves (if you cannot handle the prickly mesh).
Cylindrical piece of wood (broomstick will do) about your height long.
Thick grounding wire.
Long screws with fitting bolts, or hook-screw or make do with the wire.
Pliers and drill.

Cut 50 cm off the mesh. Fold the longer mesh in half along it's length. Ensure that the edges are level. Put the gloves on and, starting from one edge, fold 1 cm along the length of the long end. Fold again, flatten, then staple to the end at 5 cm intervals (see fig. below).

Repeat this procedure on the short end, leaving 15 cm unfolded (see fig. below).

If you do not have a stapler, then cut 2 cm long wires. Fold each piece at its middle in a "v" shape and hook ends outwards (see fig. below).

Place on the folded strip of wire mesh as you would a clipper around paper, and clamp in place with a pliers. Repeat along the folded length at 5 cm intervals. At this point, the mesh should have one end open (see fig. below).

Cut the 50 cm piece of mesh in half along its length. Most wire mesh comes in rolls 120 cm wide therefore you should get two strips each 25 cm wide, 120 cm long. Fold each in half along the length and flatten. Place the two together and fold a further 1 cm on the folded sides then flatten. Fold one end twice at 1 cm, Leave 3 cm unfolded,  and staple (see fig, below).

 Place inside open corner of bigger mesh, aligning of the shorter side of cage. Proceed with the folding where you left off and leave 3 cm unfolded.  Staple or clamp the folded part (see fig. below).

Take the top three layers where they meet with the cage (should be about 120 cm), and fold twice outwards at 1 cm, then staple or clamp with wire at 5 cm intervals. Repeat on other side (see fig. below).

The remaining length should be folded twice at 1 cm, flattened then stapled/clamped at 5cm int. Ensure the point where the side meets the door is given extra attention (see fig. below)

Proping up
You will need a long bolt, preferably with a hook, with two nuts and two washers on it (see example below).

The alternative is a hook-screw or wire. Screw a hole in the middle of the stick for the screw. Place the stick inside the cage and align it in the center. Screw one bolt onto the screw and slip the washer on. With one hand holding the stick inside the cage and the other outside, pass the screw through the mesh from the outside, through a washer and screw into the stick. Screw in place. Fasten the nuts around the washers so that they hold a wider area of the mesh in place as such prevent the formation of a hole. If you cannot get your hands on a screw, nuts and washers, then a hook screw or wire will do. The disadvantage of the last two materials is that they will  eventually give you work fixing the cage where spaces appear. The hook-screw should be screwed into place from the outside, and the wire should be wound firmly around the stick then protrude outwards through the mesh. 

Tie a strong string to the ceiling. Ensure that it does not slant as this could increase side forces on the hole in the mesh and widen it. Ensure that the top of the cage rises to about 50 centimeters before fastening the string. You can always adjust this height to fit your preference later.

The earth should be screwed into a corner of the cage with an attachment as shown below.

This example is bolted into hard metal. The mesh will require a washer and bolt on the other end. Do not tie, hook, or use any spring based clamp to attach the wire. Due to the loads and sharp fluctuations in currents involved in attacks leaks will be caused which will make the cage unsafe to sleep in. The same measure should be applied when attaching the wire to the earth outlet. Do not use plug-in sockets. Find the ground wire even if it means opening the socket. It is usually green or green and yellow in color, and screw directly to it. Do not attempt to do this yourself if you are not knowledgeable in electricity matters. Find an electrician to do it for you.
Finally, you will need to make the parts to ensure the entrance does not leak microwaves into the interior. If you have the skills, then you can place a zipper on the entrance. Otherwise cut at least 12, 3 cm long wires and fashion them in the same manner instructed with the clamps. Bend until the ends are about 0.5 cm apart (fig. 10).

Enter the cage by pushing the unstapled folded parts apart. Slip one part of the door over the other again and secure by placing the wires like clips over paper at intervals of 5 to 10 cm. Ensure that they are easy to put in place but can only easily be removed with the fingers, not by limbs and other body parts knocking or rubbing into them.

And you are done.

This single layer faraday cage  will give good protection from microwave intrusions, but may not block all attacks. From experience, the ideal number of layers for effective shielding starts at 2. Follow the instructions above to create an extra layer that should be slightly longer than the first layer. Slip the first layer inside this second layer. You will have to redo the entrance. The number of layers should be the same throughout the structure. Only in the single layer example does the door have to have more layers. This is in keeping with the need to fold away prickly ends. This cage easily fits in a medium sized bag when folded and can be carried along when you go on trips.

If you are still being reached inside the cage, then:
-Consider increasing the layers
-Check that your perps are not using ultrasonic beams. Check your sound defenses or get them if you have non. They are usually easier to place than metal shields.
-Check the ground wire. Ensure that it is still firm. You may need to make a habit of unscrewing then re-screwing your ground connection even when you are sure there is no tampering. Some frequency attacks tend to create oxidization that may increase insulation at linkage points. It is essential to regularly unscrew and soft sand these parts before putting them back together again.
-Increase the size of the drainage or ground/earth wire. The thicker it is, the better.
-Avoid leaning or placing metals bigger than the average plate on or near the cage as they may be used to create hotspots of an intensity that will easily extend into the interior of the cage.
If this design makes you claustrophobic, then consider using the same methods to construct a cage that is shaped like a tent. 

Order a Personalized, Hand Made Faraday Cage
I am also prepared to make cages for targets. I will send packages internationally. Procedures will be followed to ensure that the contents are not tampered with. Email me to make an order. Each cage will cost $ 50 minus postage.

The idea for this little beauty comes from a demonstration I watched on YouTube in which a scientist is shielded from an electromagnetic discharge. I should say that sleeping in this construction has helped tremendously. The damage that was being systematically inflicted and gradually disabling me was either stopped completely or significantly reduced as soon as I started using the cage. The heat spots were no longer felt, the profuse sweating stopped. A spring returned to my gait. I also discovered that I was having dreams again ... Real, natural, vivid, sweat dreams.

Hi, its pleasant piece of writing regarding media print, we all understand media is a impressive source of information.

Mukazo Vunda: I am looking at the same article. You are everywhere my friend. I tried to assemble a larger faraday cage but I am not good with tools.

bro can you do something similar with mylar heat blankets? i hear they operate sufficiently well enough to stop the emf's. Cheers!
