Quadrifilar Antenna for NOAA APT Satellites

Quadrifilar Antenna for NOAA APT Satellites
Today, America and Russia have meteorological satellites orbiting the earth every hour, as they transit thought the planet, they beam down images with a visible, mid-near infrared or infrared spectrum. With infrared is possible to identify clouds even at night as well as the temperatures of the land, sea or cloud tops. This signal is fairly weak, so I need a big antenna. There are several types but the best choice is the QFH (QuadriFilar Helicoidal) Antenna which have the right polarization for this type of signal and it’s easy to build.

Making an Arduino Based Levitron

Me and my college group made this machine for Physics Class, so I decided to show how we made it here. The final machine can levitate a magnet smoothly for days! What the hell is Levitron? In short, Levitron is an electromagnet controlled by a micro-controller that “levitates” a permanent rare-earth magnet by alternating the coil current. If done quickly, it creates an illusion of levitation. How it works?
