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 found this circuit in an article in Electronics Now magazine from March 1996. The frequency is limited...
This circuit provides a good audio power from a signal at least 1 V of amplitude. The MOSFET must...
This converter can be used to send information remotely from linear transducers, converting...
