reDIY is an open source bluetooth speaker project. We are intending to allow people to create a simple, inexpensive bluetooth compatible speaker. Every type of Maker has an option with this project. You have the option to buy all the pieces and just start using it, or find everything yourself and get down and dirty with the code. What ever your level of knowledge, we’ve got a version for you.
It is an ongoing project and we’re still ironing out lots of details. So right now this instructable is not considered complete. But feel free to take the idea and run with it.

Adafruit Mono 2.5W Class D Audio Amplifier – PAM8302: This super small mono amplifier is surprisingly powerful – able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) – making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. There’s even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain.
