This is my first instructables so I would appreciate any tips or comments you might have. Feel free to ask questions at the bottom. I will try to answer them quickly. I would also appreciate it if you vote for me. All right, intructable time!

Step 1: Gather Parts and Tools
The parts are:
(1) LM 386 ic (I got mine at Radio Shack) Just type it into the net and you will get plenty of results.
(2) Battery (3-9 volts) (I used a cell phone battery.)
(3) A small casing (I used a small mint tin) - it was almost to small. An Altoids tin would be perfect, but in my jungle town I don't
know of any place that sells them. I use whatever I can find.
(4) Two 3.5mm input jacks. (I got mine from an old circuit board that I got at a thrift store the last time I was in the U.S.)
(5) Wire - the thinner the better. (I got mine from an old printer cable.)
(6) A potentiometer (pot) - the smaller the better. (mine was a 100 ohm pot)
(7) Some sort of charging port.
(8) A small switch
(9) A small speaker. (I don't know what type mine was. I got it from a old circuit board.)
(10) Optional - A 3.5mm audio tip. (I got mine from an old headset.)
(10) That is it!
The tools are:
(1) Soldering iron (And basic skill in using one, but if you don't have the skill you need to start sometime.)
(2) Drill or some way to make holes in the tin.
(3) Wire strippers
(4) Plumbers tape (I like it to wrap thin wires with it.)
(5) Helping hands are helpful.
Lets get to the circuit! It is simple!
Step 3: Fabrication Time
Step 4: Boxing Stage
Step 5: Boring Stage - Literally
I thought the tin casing I used would be able to hold everything, but with the added speaker and the size of the battery. It wouldn't quite close - thus the rubber band. :) If you have a smaller battery it would be great.
Step 6: Cramming Stage
Step 7: Finished
Until next time,
