This is the receiver for the previous circuit we found in the December 1992 Radio Electronics magazine. The sensor is a photodiode that must have optical features such as lenses.
This power supply was originally created for the CB16760E (Loudness System) but can be used in any...
Found in 1980s Electronic Engineering, this circuit uses common phototransistors as sensors. The...
