Help me with my first DIY project
Hi everyone! im new to this world and i wanted to start my first diy build for a bluetooth speaker. could you give me some tips? I started by choosing a USB-C 12,6v charging module wich i would then connect to a 12v Bms for my three 3,7 18650 lithium batteries.
from the Bms it would then go to a switch, then to a voltmeter to indicate battery percentage, then to a boost converter 12-24v (wich it has been suggested me by ai so im a little skeptical about this part) the to my amplifier with built in bluetooth module wich is the ZK-MT21 with three channels. two 50w for my two Visaton FRS 7 4 ohm and a 100w subwoofer channel for my FaitalPRO 4FE32-4F. any suggestion on what to change? (pls be gentle with the comments, as i mentioned before i litteraly just started and made this build to try something out)
