Caixa Bluetooth parou de carregar? Resolva com Diodos de Sucata!

In this JC EletroMec video, I present a definitive solution for when the original charging circuit of your Bluetooth speaker burns out. I'll show you how to neutralize the damaged USB connector and adapt a robust system using scrap diodes and a new power plug. In addition to the repair, we took the opportunity to perform an upgrade: we installed an extra battery to double the storage capacity, making the speaker "turbocharged" and with much more autonomy. What you will learn in this tutorial: How to identify defects in the charging circuit and USB connector. How to use a multimeter to locate polarities on the board. The technical schematic for using diodes to reduce the voltage from 5V to 4.2V (ideal voltage for lithium batteries). Soldering techniques and professional insulation with heat shrink tubing. How to connect batteries in parallel to increase amperage without compromising safety. This is a basic electronics project that uses recycled components, ideal for those who enjoy DIY and equipment maintenance.
