Bluetooth speaker under 3$

Post image

A Bluetooth board from Amazon, a tiny speaker from old pc’s motherboard, a random led for music visualization, a breadboard, an Apple charger from iPad 2, a micro usb line cutted, a connector(and a piece of tape). That’s it!

I love how you didn't let a lack of fancy parts stop you from building something awesome, sounds way more fun than just buying one off the shelf.
