Rather than move your potentially cumbersome audio system outside to enjoy some music, you could just use your iPod, iPhone or any other MP3 player hooked up to some speakers. The gadget is perfect for enjoying your music out in the sun. Based on just 6 hours to fully charge the speakers, you’ll get up...
The Gramo Speakers are the creation of Pekka Salokannel. The speakers fold out into a gramaphone-styled speaker that you can connect to your music player. The top three panels of the speaker contain solar panels which are used to top up the battery on your MP3 player or iPod.
It appears that the Nintendo DS Lite was made for solar panels, as the Instructables author dark sponge has created a useful solar charger for the DS Lite. The top face has enough space for two 60x60mm solar cells side by side, each outputting 3V at 40mA.
