Yesterday I ended a new project. This time I made a pre-amplifier out of two old PC speakers.
The thing was not very difficult and it wasn't a challenge for me. I added a new function which is very useful. It consist in a button that lets you get the signal bypassed, so instead of removing the thing when you don't want an amplified sound, you just press the button.
It looks fine. I hope not to have problems with heat .
By the way, the LED you can see in the pictures is beautiful purple (instead of blue) and brighter.
