This time I made an bluetooth speaker. It’s very easy, you basically only need a power source, a bluetooth modul and a speaker.

You can use basically everything as an enclosure if you don’t mind about poor sound. If you choose an unusual enclosure, you can get something out of the ordinary.  I took a gasolin tank.

This are the components i used: 1x speaker (Visaton FR 13WP), 1x bluetooth modul (Typ TDA 7492P), 1x switch, 1x green led, 4x screws and t-nuts, 1x terminal wire connectors, 1x lead-gel battery 12v, 4ah, any kind of  enclosure.
