Found in the September 1998 issue of Electronics Now, this circuit uses an encoder with reed switches. The circuit indicates the position of a “indicator” and thus the direction of the wind.
This non-regulated power supply uses a single secondary winding transformer. The secondary voltage...
In the figure we show how to connect a power MOSFET to the output of a CMOS function to control a power...
This simple photometer uses a 1 mA milliammeter and a common phototransistor. The circuit has its...
