This is the hand crank radio I recommend. Plus, it always makes sense to stash a backup AM/FM/Weather Band radio, just in case.You can use this hand crank radio to power up a cell phone to make a 1-2 minute call in a dire emergency....
Note 4: θJC represents the thermal resistance between the chip and the top of the package case. Note 5: Maximum power dissipation for the device is calculated using the following equation: PD TJ(MAX) θJA - TA Where TJ(MAX) is the maximum junction temperature, TA is the ambient ...
structure. In the case of the carport that I had built, I grounded the imbedded screen because I knew that the wire leading to ground would not act as more of an antenna than a ground for the shield. Although most small faraday cages should not be grounded because of the "accidental ant...
Bee colonies in many areas have been suffering serious losses for several years. "Colony collapse disorder" has been suspected to be possibly from a virus or mold, from nicotine-based pesticides used in agriculture and/or due to Electromagnetic Fields (EMF's), including cell phone transmissions,...
So, be sure to have your cell phone protected. Or you can learn here how to legally turn your CB car radio into a powerful transmitter capable of emitting and receiving communications from hundreds of miles away. The ability to communicate over a distance is the cornerstone of coordination ...

You quickly retrieve your fully functional cell phone from your foil-lined trash can, a.k.a. Faraday Cage. And presto, you have one of the very few functioning cell phones in the Northern Hemisphere. Congratulations!Did your plan pay off? Yes and no… How many bars do you have? None?
The reason I'm not counting the cell phone is because it's useless to me sitting in a metal box. I'd need enough warning to put it there during the EMP, which is unlikely. But I could create a metal box big enough for my handheld ham radio and ...
If a cell phone presents a danger to an airliner, a nuclear electromagnetic pulse would present a severe danger. Aircraft flying at high altitudes are much closer to the "source region" where EMP is produced. In the lower atmosphere, the EMP field strength is fairly uniform over large ...
case you are not home during the event. Children and teens should know their duties in this regard. Make it part of the drill. If you have a shower that's not occupied with a waterbob, take a shower, which may be your last for some time to come. And while ...
