DIY Perks | Homemade Bluetooth Boombox - Build Log @DIYPerks | Uploaded October 2013 | Updated October 2024, 12 hours ago.
This is how I made my homemade Bluetooth boombox. It cost about £50, and sounds better than the Jawbone Jambox, which is saying something. Out of all of the things I've built, this has got to be one of my favourites.

Here is a list of parts, searching ebay (worldwide) directly for the quoted items should allow you to buy the same ones that I bought from China.

15w Amplifier - "ta2024 amplifier "
Bluetooth module - bluetooth audio receiver usb"
Voltage converter - "12v to 5v buck step down"
Battery charger - "SC Fast Charger for NiCd/NiMH batteries Vapextech"
Ground loop isolator - "ground loop isolator"
