I believe it's time to graduate to Faraday cages. These tinfoil helmets just aren't cutting it anymore.

  1. In high school we went on a field trip to WTMJ - Milwaukee's highest powered AM radio station.
    (It had so much power that at my folks home, 3 miles from the radio towers, you could pick up the phone, dial one number to clear the dial tone and then listen to the radio over the phone.)
    So powerful I built a radio consisting of a piece of pencil lead, a safety pin, a D-cell battery and an earphone. The pin held the lead against the edge of the razor blade. The battery was connected in series with the earphones, the pin and the razor blade.
    Tuning was accomplished by varying the pressure on the lead.

    Anyways, I digress.

    At the station they had a Faraday cage containing their transmitter equipment. It was an entire room, about 10 feet square and fifteen feet high with the walls all covered with copper screens.

    The power tubes were awesome. Vacuum tubes about 4 feet high and 18" in diameter all glowing a pulsing blue. Pulsing with the audio peaks and lulls.

    For the senior year science fair project a friend of mine and I built a six foot tall Tesla coil. His dad worked at a local electronics company and he wound the main coil for us. Hundreds of feet of wire as fine as your hair wound up on a 6 foot long cardboard tube. The capacitors, 3 of them, were 24" square panes of glass with foil glued on each side. The power supply was a 15,000 volt neon sign transformer. It also had an adjustable spark gap to make it all work.

    It was really cool with the spark gap sizzling, the capacitors glowing and 6 foot long sparks jumping into the air off the top of it.

    It had a needle point at the top and we fashioned a set of wires onto a hub and bent the wires like a swastika. Set upon the needle it would start to spin from the electrons jumping off of the wire tips. Soon it would reach a very high RPM and a shower of sparks would fly off forming a disk of electricity.

  2. We need to start a polar bear survivalist camp now... well... or maybe if the ice holds we can move somewhere warmer, but we gotta do our own food and tote guns... and adopt smart kids to teach how to build a utopian society on whatever will be left.

    Face it. If lefties won't join the Tea Party Movement, this is total fascism and total war....

    A bell pepper, ONE small bell pepper, is $4.00 at the store I can walk to... and I'm going to be on foot damn soon. It should be a bunch of boomers who revere truth and kids who need to learn to revere it above everything.

  3. Cool BB2! The tubes that light up bright blue are the rectifiers.
    99 ~ Those prices prices are outrageous.
