Do you have wired speakers that you no longer use? Don't throw them away! In this video I'll show you how to give them a new life, transforming them into working Bluetooth speakers. A simple project that everyone can do, ideal for reducing waste and saving money! The 3.7v 3000mah rechargeable lithium ion battery that I use in this video for this speaker has a tested life of more than 12 hours at maximum volume.
