Introduction: CHEAP Bluetooth Receiver 10 Bucks
I bought a groove cube Bluetooth speaker from Wal-Mart for 10 bucks an some change. now of course it sucked, but it's being repurposed anyways.
Step 1: Take It Apart.
I used a small regular screwdriver to get in between the outside cover an the bottom cover where the power bottom is. just went around an popped the bottom cover off. now inside is the chip, battery, an a really small speaker.
Step 2: Speaker Pins
here are the two speaker terminals. where the head phone Jack will be soldered in.
Step 3: Drill a Hole in the Side of the Cover
pick a bit that's a little smaller then you wire. I also used a small zip tie to keep the wire from being pulled out.
Step 4: Solder It Up.
ground to ground an the two speaker wires to the positive pin.
Step 5: Put It Back Together an There You Go. Plug It in to an Audio in or a Aux Port. Trim It on an Connect.
there ya go. eazy peazy

Just took one apart, more to make a smaller closure (I wore it around my neck in a noisy area to hear the ring). The top was glued + snapped, but came off pretty easily, bottom (speaker end) was four pin in hole (broke one). The speaker is wedged between the closing and the "main" plastic part. Mic is in the button end closing part.
Trying to figure out the ICs (and perhaps the circuit), the small ones are an amp and a 4Mbit SPI eeprom. I can't find the bluetooth module(/likely cpu) though. Great work - I bought it for the same reason but just now getting to it. It's only $5 now too, if they have any left (tons of $5 bt speakers around on clearance).

Great idea! This would be great on my dagco 20 watt transmitter I bought. Now I can play my pandora station and have the whole town hear it.
