In this 2001 circuit we have the way to trigger an SCR with a phototransistor. The circuit appears elsewhere in this section, obtained from publications from different eras.
We present a DC-DC converter circuit that can operate with input voltages from 2.4 V to 14 V and...
This compressor circuit was obtained in a Motorola manual from the 80's. The components are from...
This complex circuit was found in the 1993 edition of the Electronics Experimenter's Handbook. Most of...
