DIY lm3915 audio level indicator Electronic Kit / Soldering Kit

 

This is a great little kit to compliment your radio project or almost any project that has an audio output you would like to check.

Not great for large stereos or boom boxes but a low-voltage project would be the best fit.

I myself use it to check the audio outputs of my Ham Radio projects to check the performance of such chips as the LM386. 

And many more price/$9

Great Stem learning kit
