Building upon my last video, I’ve decided to make a simple circuit using some op-amps. One is the general op-amp LM741. The other is a specific op-amp, LM386, that is designed for audio amplification.

This circuit can be used to amplify microphones or be used as a circuit sniffer depending on what you connect to it. There is a lot of room for experimentation with this circuit to make it work for different applications. In the video I go over how to make a sniffer probe that can be used in DC electronics troubleshooting.

The schematic for the project can be found here:
