This is the second article in a multi-part series on writing PICAXE BASIC code. It introduces the for...next command, the wait command, general purpose variables, the symbol command, and the #no_data directive.

We review switching losses involving diode recovery charge, transistor switching with clamped inductive load, device capacitance and leakage, package, and stray inductances, and the efficiency versus switching frequency curve.

Antennas provide the wireless linkage required for any satellite-based system. Here's a look at the many antennas of GPS.
