I finished my bluetooth speakers that hook up to some old computer speakers. Streaming music from my phone or computer from anywhere in my home. It is not as loud but I could always incorporate an additional amplifier into the circuit. Before I packaged it up, I had everything completed on a perfboard and ensured everything was working. It was not powering at first but it was because I forgot to Ground the board :-/...after that everything worked great.
I packaged it up in a small project box with a 3.5 mm audio jack and it is powered from a 3.3V wall adapter which supplies plenty of current for this project. The two LED's are status LED's to see when someone is connected. Fun and pretty simple project putting some old speakers to use.
Yes, indeed it's a great invention. Bluetooth speakers have good sound quality but when it comes out for outdoor fun, it lacks a bit. This device can sort out this issue. Thanks for this sharing..

ReplyDeleteGoing to graduate school was a positive decision for me. I enjoyed the coursework, the presentations, the fellow students, and the professors. And since my company reimbursed 100% of the tuition, the only cost that I had to pay on my own was for books and supplies. Otherwise, I received a free master’s degree. All that I had to invest was my time. best bluetooth speakers under 5000 in india
