Looking for a good old-fashioned way to enjoy listening to music on your phone? Why not build your own gramophone-style resonator, like C.E. Dyer did using some beautiful upcycled materials, including a 1930s DuPont explosives container!
It uses no electricity except that of your charged phone. The inside of the box can still be used as storage for anything you wish to hide. Please listen and enjoy.
