OpAmps Project: Build an Amplified Stereo Mic Kit
In the previous lesson, Karen talked about how op amps work and the many ways they can be used. In this episode, Karen assembles the Velleman MK136, Super Stereo Ear Kit. This kit uses a NE5532 Op Amp to boost the audio input from two onboard microphones to an audio output jack. While a speaker is not included in the kit, there is a potentiometer that acts as volume control. Follow along as Karen walks you through soldering the kit together and then see it in action!
