Advice on first bluetooth speaker build
I live in rural Swaziland and have little access to things, and very low funds, I am using this project to teach kids at an orphanage how to plan, purchase and solder an electronics project.
The basis for the project:
I have a busted desktop speaker set that I want to transform into a battery powered speaker set. I have a friend coming from the US soon that can bring me a couple of small items from amazon.
What I want to achieve:
Be able to run the speakers from mains or battery
Connect and play via bluetooth (aux would be a bonus, but hardly needed)
Have a volume knob.
Supplies on hand:
24v 2a power brick. Could probably find a 19v laptop psu if needed.
12v2.2ah Sealed Lead Acid Battery
2x 5w 4ohm drivers
3x dual potentiometers from the busted speaker set. (originally Volume, Treble and Bass)
Would this board be suitable for driving the speakers, and can I solder on my own POT for the volume control.
What charging board can I use, that could work with the 24v 2a supply?
Does anyone know if this board would have the characteristic ground loop noise, and is there a way to mitigate it?
