This kit includes all of the necessary electronic components to craft a mini wireless speaker—you build the speaker cabinet in the shape and material of your choice. You can use a simple block of wood with a hole drilled in it, or build a hollow cabinet with fancy joinery—it's up to you. You can also get creative by integrating speakers into furniture, cabinetry and other commonplace items. The speaker connects wirelessly to any Bluetooth enabled device. The kit includes a single full-range speaker, a control pod with on/off button and USB port, and a USB cable, which is used to charge the internal battery. The speaker and control pod are held in the cabinet via friction fit. Just use a 1-7/8'' hole saw or Forstner bit to drill the holes. You can also use a jig saw, as the bezel will conceal any rough edges. No soldering is required.
