Here’s a fun and cheap project of using (recycling) paper cups and a pair of spare earphones to make your own speakers.  All you need to do is to cut a cross (X) at the base of the paper cup, insert the ear-buds, and you’re done!  For the speaker holder, I simply place it on top of another paper cup, but you can use a toothpick/sticky tape to attach them together.

The sound amplification wasn’t very big, only audible when increasing my sound volume to max levels.  I suggest positioning the speakers closer to your ears and playing it in a quiet office environment.

Enjoy your coffee!
