Self-Winding: Shake MP3 Player

The Shake MP3 player by Kenneth Tay makes use of kinetic energy to keep the batteries charged, similar to modern timepieces. With the hold button switched on, shake it a few times to get the juice. Conversely with the hold switch off, the shaking pauses/plays music.

From the designer: "An electromagnetic coil is connected to the battery, converting kinetic energy into electrical energy that charges the battery.

The player connects to the computer via USB cable through the headphone jack, facilitating the transfer of songs as well as the conventional method of charging."
