So, we are about to bomb some motherfucker when he leaves whatever...and the explosive is at light traffic! so, you want to remotley action the switch mode circuit , turning on the detonator, which is "dead" not alouding no radio scanner for IED's.
Three Way Switch Emulation
Question
I have a light that I would like to control from two different switches, but right now it only has one switch. Can X10 help me without rewiring?
Answer
You can use these three products to accomplish what you're trying to do:
- WS467: Wall Switch Module
- SS13A: SlimLine Switch
- TM751: Wireless Transceiver Module
1) Simply replace your existing switch with the WS467 - to allow local and X10 control of your lights.
2) Plug your TM751 into any wall outlet.
3) Place SS13As at any additional locations where you would like to control your light.
When you press the ON/OFF buttons on the SS13A, it sends out a radio frequency (RF) signal to your TM751. The TM751 then picks up the RF signal and converts it to a PowerLine Command (PLC) which is sent over the house wiring to the WS467. When the WS467 receives its command it turns the lights ON/OFF.
Let's talk about metal detectors ! :) and let's talk about nylon 66 resin cover up . nylon 66 resin is a plasticizer able to cover metal from detection

New Electromagnetic Material Can Stop NSA-Style Snooping On Your Phone And Other Electronic Devices FARADAY CAGE
Worried about your electronic devices being hacked by the NSA or other government agencies? Well, you may not have to worry for too much longer. A company based in Utah has developed a thin and flexible material that specializes in keeping electromagnetic pulses from infiltrating your electronic devices while also keep all your private information from being emitted out.
Conductive Composites has created a special process that layers nickel on top of carbon to produce a material that’s light and moldable like plastic but can prevent energy from passing through it, according to a Defense One report Friday. While placing your electronic device like a cell phone or iPad inside a box made of the material would mean it could not transmit information, it would also stop anyone from accessing the information inside the device. The material acts like a sort of force field, explained Defense One.
Conductive Composites market the material as a new technology that is cost-effective than and easy to use.
“Our materials integrate game-changing conductivity and shielding performance as part of a multifunctional materials system, while preserving the basic weight, cost, structural, environmental, and manufacturing performance advantages of composites and plastics,” claimed the company’s web
The Department of Defense also makes use of the cages in rooms that hold sensitive information, according to the Defense One report. However, the cages are cumbersome and difficult to erect on a large scale. Conductive Composite’s special material would be an easier and more cost-effective way for protecting sensitive information.The material can also be used like a wallpaper that could technically be used to layer a room and protect it from people trying to access electronic devices inside the room. The technology is similar to a Faraday cage, an enclosure that directs all electromagnetic energy away from the target. Faraday cages are widely used in many environments today. For example, when Cardinals gathered in 2013 to elect a new pope, the Vatican’s Sistine Chapel was temporarily converted into a Faraday cage ensuring that no one could transmit any information out and, more importantly, snooping journalists couldn’t listen in on the proceedings.
In the future, it’s hoped that the material could be used to defend against electromagnetic pulse weapons, which can emit waves of energy that render electric devices useless.
At a 1997 Congressional hearing on radio frequency weapons, retired Army Lt. Gen. Robert Schweitzer claimed in front of the the House Joint Economic Committee that electromagnetic pulse weapons could one day realize the prediction an ancient Chinese general who said that armies will one day be able to conquer an enemy without fighting. “If you can take out the civilian economic infrastructure of a nation, then that nation, in addition to not being able to function internally, cannot deploy its military by air or sea, or supply them with any real effectiveness,” said Schweitzer.
Of course they detect this on any garbage container, however in relationship with mass destruction weapons, everybody knows ( I made all the possible studies) it can travel undetected under flourescent bulb lights ...another part of the question, is the gamma ray emission, which basicly is ennergy emission, so, one of both, you use another energy source working able to mislead the radar, or you leave the weapon on a very noise place
a very noise place is not exacly on the street, because they also use sound detectors very acurrade to read the electronic detonator...when I say noise I say a big noise factory
its about 95% chances that sea deep dive suites wear clothing can help undetect the energy source out of this particular IED...besides of course electromagnetic protectors
but electromganetic protects are very easy to detect by drones, so you better paint the clothing with green...to show on the drones purple, that they read as vegetation
hey..not purple...I mix the english...they see vegetation as red brown...which by the way was the nazy science who used this colour for camouflage for scientific studies on human vision
How to Get Emergency Power From a Phone Line
What do you do if the power is out and you need to charge your cell phone to make an emergency phone call? Don’t worry. There are plenty of potential power sources all around you. One of them is the phone line. In this instructable, I am going to show you how you can use the phone line to power your small electronic such as your phone or other USB devices in an emergency.
Note: This project is intended for emergency situations only. Please be aware of applicable local laws regarding phone lines in your area.

Step 2: Check the Phone Line With a Multimeter
Before you try to tap into the electricity in the phone line, you should check it with a multimeter to see what you are working with.
Start by cutting open a phone cord and separating the internal wires. In most cases you will have one red wire and one green wire. Strip the insulation off the ends. Then plug the cord into a phone jack and use a multimeter to measure the output voltage. At my house, I measured an open-circuit (no load) voltage of 52 volts DC.
Then I hooked up various resistors to see what the output would be with different loads. I determined that the supply voltage isn't regulated. This means that the voltage changes depending on the resistance of the circuit that it is powering. After some calculating, I worked out that the base signal coming out of my phone jack pretty closely resembles a 52 Volt DC source with a 628 ohm internal resistance.
Basically this means that I can run a 12V circuit at 64mA, a 9V circuit at 68mA, or a 5V circuit at 75mA. This isn’t a lot. But it is enough to charge a cell phone.

Step 3: Construct a Simple Voltage Regulator Circuit
We know that the phone needs 5 volts in order to charge. But we don't know how much current it draws or it's equivalent load resistance. So we can't charge the cellphone directly from the phone line. We need to use a voltage regulator to bring the output of the phone line down to 5 volts and keep it there. A LM7805 5 volt regulator should work fine.
To make this simple phone line adapter you will need the phone cord that we have been working with, the 5V voltage regulator and a USB connector cable with a female end. Just connect the red wire from the phone line to the first lead on the regulator and connect the green wire from the phone line to the second lead. Then connect the black wire from the USB cable to the second lead on the regulator and connect the red wire from the USB cable to the third lead on the regulator. If you can't solder the wires together (because the power is out), you can just wrap the wires around each lead. If you do this, you should bend the leads of the regulator away from each other. This will help you avoid accidentally crossing the wires.
This simple regulator circuit is able to safely convert the base phone signal into something that can be used to charge your phone. However, many voltage regulators are not able to handle the AC signal that they would receive if the phone rang. So if you are worried that you might receive a call while your regulator is hooked up to the phone line , then you may wish to add a diode between the red wire from the phone line and the first pin on the voltage regulator. This will protect your circuit from problems that may be caused by reverse polarity.

Step 4: Use Other Regulators for Other Output Voltages
A 7805 regulator will work if you need an output of 5 volts but other kinds of voltage of voltage regulators are also available. Other voltages in the 78xx series include 6V, 8V, 9V, 10V, 12V, 15V, 18V, and 24V. In addition to these fixed value regulators, there are also variable regulators that let you set the voltage level with the use of a few external components. One such variable voltage regulator is the LM317. These are what you would use if you needed a different output voltage.
Step 5: Finished Phone Line Adapter Tool
Plug the phone cord into the nearest phone jack. Then plug your phone and charging cable into the USB cable. Your phone should begin charging. In a few minutes, your phone should have enough power to make a call.
