DIY Bluetooth Speaker PCB
DESCRIPTION
In this instructable I will try to show you how to make a Bluetooth Speaker from old pcb board.
I had a broken Sony srs-xb30 speaker from a friend. The case was smashed but I could save the speakers and the electronic parts. I had to make a new case and I wanted to make it look better than before :).
You can use any other speakers and amplifier with the same result.

Warning: It is very important to use safety equipment, safety goggles and mask!!
Use a soldering iron and try to remove as many pieces as you can from one side of the pcb board.
Use a heat torch to remove all the other pieces.
Remove any other bumps or pieces with sandpaper
We need to make a box. Use a table saw to cut 2 pieces of pcb and 2 pieces of plxiglass for left and right side (same size). Also 2+2 pieces for top and bottom and 2+2 pieces for front and back. You can make it as big as you need for your speakers.
Mark the place for speakers and protection grill
Use a fretsaw to cut the holes for speakers and speaker protection grill.
When cutting plexiglass use oil to prevent melting.
Use a metal file to remove any imperfections.
Make holes and use a tap tool to make thhread for screws.
Cut a piece of aluminum grill and use clamps to hold it between two pieces of wood. Use a hammer to bend the edges and make the speaker grill covers.
