Introduction: Make Your Own Simple & Cheap Portable Bluetooth Speaker

has anybody had any problems with the battery charger board

the ones i have seem to trip the overcharge when switching on when using the batteries but it is ok when i use a 5v mobile phone charger

Can you charge up the rechargeable batteries with an external solar power pack like the ones for charging phones

I made this but when I increase the volume about 90% to 100% the speaker stops working and the light on the Bluetooth board get off and the music stops.what can be the problem?Pls help me

which resistor did you use on the led. Thanks

if I wanted to add tweeters, would I need another amp and more battery power? If so what do you suggest. Thanks

Hello Scott! Another great project! Thank you!
I have a question about the very loud voice, which screams at me every time at the start! Is there a way to turn this off or to make it at least quieter?
Many Thanks!

Great project !! I am currently doing it so thnak you for this great tutorial. I had just a problem for soldering the battery together (dangerous, no spot welding etc...) so I buy this case holder. I hope it will be fine, but at least it's not dangerous ^^

Thank you again ! It's my first DIY project and it's thanks to you =)
