Re: pic: Secret part of my newest vexbot

Before we get too crazy here, the microwave used for communication is a relatively low power device connected to some high gain, directional antennas. Most are not harmful unless you choose to climb the tower and stand in front of it. Radar installations create more power than these in the picture. For those of you who are RF inclined, the brass cylinder sticking out the top of the magnetron is actually a 1/4 wave antenna used to couple energy into the cavity of the microwave.

Please Tytus, tell me you were careful when you extracted the device from an oven. There is some really high voltage capacitors that can hold a charge for quite a while that are connected to the magnetron.
