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.

Step 5: Add A Switch

Drill another hole and superglue a slider switch.

what is the quality of the sound ? do you hear digital noise at low volume?

Where did you get the speakers?

It would be real nice if you can mention the source of the 5W neodymium driver.

Nice amount of material you reused for this one! If available, you could use jigsaw and hole saw for smoother cuts and less melting - sanding later.

Good Instructable! I think I will make me one during my summer vacation! Thank you.

Nice job! This will be great when we're sitting around the fire pit.

I'm going to show this to a couple of guys I work with (one of which has done 3 Ironman triathlons... makes me exhausted just thinking about it), and point out that it fits nicely on bike handlebars. A 'short' ride for them is 30-40 miles, and this is a whole lot safer than wearing headphones.

Nicely done... It will go well along Nokia Lumia.
