Over the past week I tried to make this Instructable: USB Powered Speaker. I thought it would be nice to have a speaker with an IC and adjustable volume, and was interested in the idea of powering it from a USB port rather than a battery.
I tried assembling this circuit on a breadboard, but it's not working for some reason. I've tried various things, including powering the circuit with a 9V battery rather than a USB port, but with no success. Perhaps the LM386 chip I'm using is blown, but it wasn't when I checked it a few days ago.
Attached are two pictures of my setup. Sorry for the poor image quality, but I'm hoping they can be of some help in diagnosing the problem.
