Cheap 12V CD for the camper

[MtnCamper]

Got an Walkman CD player, and old set of computer speakers? Cut the 110 plug (transformer) off the speakers, the solder up a 12V plug. Even if your speakers are 9V, they still work.
 
Plug the speaker into your headphone jack on the player, into 12V outlet and there is sound! Small, cheap, probably got all the things you need around the house.
