Introduction: Eissa

Picture of Eissa

This was one of the first circuits that got me into making. It's very simple and can be used to amplify audio output (mp3 player, computer, etc.) as well as electric guitars.

Step 1: Eissa

Here is a sketch of the circuit I use. It's not drawn in any traditional sense. But it helped me visualize what I was trying to accomplish.
The 10uf cap marked "optional" is best left out unless you're looking to use this as a guitar amp.

Step 2: Eissa

1-Lay out the circuit on the perfboard.
2-Make a rough guess at how much board you need.
3-Score your board several times with the X-acto knife and break off what you need.

Step 3: Eissa

With everything in place, bend the leads of the components to accommodate soldering.1
Leave the LM386 out of the socket so as not to burn it up with heat (personal experience).2
Solder away!3

Step 4:

Add a power source (9 volt battery) 1

and speaker(s) 3)

Step 5: Eissa

Test circuit. 1
Add any last-minute items (on/off switch, LEDs, etc.). 2

Step 6:

That is VERY traditional - it is the way we HAD to do it in the old days - see? you really don't NEED a computer (they are nice to have though ;-))

That's a nice neat instructable - well done.
