How to Turn Old Bag Into a Amplified School Bag

I'm so bored at the end of this semester, because none of our teachers allows us to have fun. So I decided to make a device which helps us to have fun at school.

Step 1: Materials That We Need

Step 2: Schematic

Step 3: Time to Test

I decided to test the circuit before I completely solder it. So I use breadboard and some extra jumper wires for it.

Step 4: Building the Circuit

Now, we need to build it permanently.(INSTRUCTIONS ON PHOTOS)

Step 5: Start Assembling

Put everything into the enclosure and secure with screws.

Step 6: Put Everything Into a Bag

Now put everything into your bag. Be creative on that.

Step 7: Results

I'm actually pretty impressed with the results. Write on comments and let me know what do you think about it...
