Here's a simple Bluetooth speaker that's made from hacking old gadgets and mashing them up together. It sounds exactly like the big Jambox but only smaller! It has a mic and command buttons too! My friend, Angelo (ASCAS), and I made this project.
We made this project to boost up my viewers and glad to say it did. I learned how to make guides the way it should be and look I got featued in my next build the 3D Printed Sumobot so i thank my friend Angelo for helping me with this project with all the pictures and materials.
The homebrew jambox is equipped with two 5w neodymium drivers, a 2.5" passive radiator, three command buttons, handsfee mic feature and a 2250mAh lithium battery "All recycled". Closed tight with out any screws or any openings we decided it's ok since this not our final design we hope to 3D print our parts and make it smaller and probably waterproof!. Just make sure when you build this everything is working as it is everything secured and functioning properly inside and out.
Step 1: Install The Passive Radiator/ Driver
When we dissasembled our old USB powered desktop speakers we were able to get four of these passive radiators. If you're lucky you might find one. The plastic enclosure was acquired from a old organizer tray.
We used superglue to seal the rubber of our plastic enclose.
Step 2: Wiring Diagram
Before we continue, here's a block diagram of the whole device. Here's a tip, take advantage of the common ground. Don't solder too much negative wires.
Step 3: Disassemble A USB Powerbank
This powerbank was actually broken perfect for our project we just opened it up reheated the pads and it came back alive. The powerbank was cheap and all but it is quite nice its been with me for almost a year. (The battery capacity is 2,000mAh anything higher is fine). Dismantle the plastic casing and desolder the female USB port.
Step 4: Hot Glue The Powerbank
Drill a hole for the charge input of the powerbank then hot glue the circuit and battery on the enclosure.
