Introduction: Low Cost LM386 Based Guitar Amplifier

About: Hi, I'm actually an IT consultant but love engineering. I love to try, do DIY stuff which are cost effective and solve my purposes.

Took reference from LM386 datasheet and below websites.

Here is my video while I was testing it with my acoustic guitar

    The lm386 is a cool little IC. I used a simple set up with it to go to a set of LEDs instead of a speaker, and they flashed when u hit a note. Naturally the LEDs got wired into the pickgaurd.

    pls upload circuit diagrams

    this is my final video with the amp

    I guess you might think im a bit annoying, but this is also missing all the steps (like the vodka bottle lamp) - There is not much instructable in a few pictures and links to other sites with the actual information.

    I posted the links from where I took reference, but in case you need help, you can put the questions here I'll answer that :)

    Mh76dk. You have made no instructables to date. You should make something before you criticize others. I think the project was awesome! And some are better than others at organizing there thoughts onto paper. again I say make something so we can critique you!
