About: Hello! I'm Matt and I love making things. I'm always thinking of new ideas and how to make them as awesome as possible, always with a mind to share the process online. Take a look at my profile and see if th...

In this build log you can see how I built my own bluetooth speaker, and the design process behind it. Optimised for bass, the final unit beats the Jawbone Jambox, which is saying something!

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"

    I liked this instructable. Can you post a list of materials and where I could come across those items. Looks spectacular.

    I tried building one, but my speakers sound crap. Seems like it is the ground loop you talked about. Can you please do an in depth video about that problem, how to prevent and also how to fix it. I dont have those transformers from isolators :( .......

    Could you please list the speakers you used? Thank you.

    This is so great!! I loved learning the bass boost hack! I'd really appreciate it if you posted the low-pass schematic? :)

    Thanks for sharing!

    I love the design but it would come in handy if you made a little flow chart or something like that for the electronic stuff. Some people like me are not good with that stuff..
