Hello world! I have known this website for years and I love it. This is my first Instructable and I hope you'll enjoy it. Today you will learn how to make a super simple stereo amplifier from scratch. A perfect speaker for your parties!

Supplies

In order to make this amplifier, you'll need the following materials and tools:

• 2 paper or plastic cups
• Cutter
• Pen
• Hot glue gun
• Ruler (for more precision)

Step 1: First Line

Draw a line on a paper or plastic cup as shown in the picture. The length of the line must be a little bit more than the half of the width of your phone.

Step 2: Second Line

Draw another line on the bottom of the cup. It must be the continuation of the first line and its length must be the radius of the bottom.

Step 3: Lines Parallel to the First Line

Draw two new lines, parallel to the first line. The distance between the two lines must be a little bit more than the thickness of your phone.

Step 4: Lines Parallel to the Second Line

Draw two lines parallel to the second line (on the bottom), with the same length as the same line.

Step 5: Cut

Cut the 4 new lines. (see steps 3 and 4)

Step 6: Repeat

Repeat steps 1-5 to the second cup.

Step 7: Glue

Glue the two identical cups as shown in the picture.

Step 8: Test

Put the phone in the cut and turn on some music or whatever you like. Enjoy!!!
