Make your own powerfull Bluetooth Speaker with some extra features, easy explained, cheap and handy to use for less then 15$.
Maybe you have some components which you don’t need to buy like 5W speakers and some lithium batteries to make it less expensive like I did.
In the following steps I will try to explain on the easiest way how to assemble this bluetooth speaker, people who don’t know a lot of electronics will understand I hope 🙂
This speaker has a very long battery life when you use good 18650 lithium batteries.
I found 4x 18650 lithium batteries which I used in parallel and has a total of 6000mah, the speaker plays over 24 hours on the highest volume which is very loud.
You can charge the speaker with a micro USB, which is very handy!
I also added a voltmeter display wich I bought on ebay so I will know when the batteries are almost empty.
The last new thing I added to the speaker is the 5V usb out so you can charge your smartphone or other stuff.
