Gillette Portable Speaker

As someone said "Necessity is the mother of invention". This project is completely prove this statement. I wanted a speaker for my workshop computer, but I did not wanted to spend money on fancy speakers. Suddenly I saw an empty can of shaving foam laying around in my room. Tadaa! New Speakers :)

Lets get started...

1. Empty Gillette Foam Can
2. 2 3W speakers
3. 5v battry with charging circuit
4. 3W 2 channel amplifier PAM8403
5. Power Switch
6. Wires
7. Any sort of weight

At very first I cut off the both ends of the can with the help of hammer and chisel. Then added some double sided tape on the weight and sticked into the can vertically (this will help can to stop rolling). Then I marked power switch location on the can (image 4). Cut a rectangular marked hole using sharp cutter. And then inserted the power switch.

Now I connected the wiring and hot glued the components into the inner surface of the can. Added two wired thru hole one is for audio input and another is for usb charging.

Finally I hot glued the speakers at the both ends (make sure no hole left to pass air).
