The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance cavity with the surface. In this example, the Schumann resonance frequencies for the Earth are calculated.

Most satellite dish actuators send a series of pulses to indicate their position. By counting pulses the positioner knows where the dish is pointing. It is possible to use a serial port and Linux with RTAI patches in order to count these pulses, thus minimising the external hardware required for a positioner. The zip contains instructions, circuit diagrams and example code.
