  • Solar-powered MP3 playing speaker

    solar_speakers

    [Valentin] bought a small battery-powered cube speaker with a built-in amp some time ago, but didn’t have much patience for replacing or recharging the batteries. It sat on the shelf for awhile until he decided to revive an old MP3 player he had sitting around.

    He gutted a pair of solar garden lamps, retaining the solar panels, the built-in charging circuits, as well as the included rechargeable batteries. The MP3 player was disassembled, and its components were built into the speaker enclosure. The player’s buttons were relocated to the outer shell of the speaker box with a few pieces of wire, allowing him to easily control his music without having to build in a method for opening the case. Both the speaker and the MP3 player are powered by the batteries salvaged from the solar lamps, which is why he opted to mount both of the solar panels on the the side of the speaker enclosure rather than just one.

    We like it even though the speaker looks a bit rough at the moment, especially where the MP3 player’s buttons were transplanted. After a few minutes of touch-up work however, it’ll look great.
