Get ready to build a tough & rugged boombox! "RaveBOX (v1.0)" can charge USB devices, play MP3s and tune to FM stations! It also comes with an IR remote offering better convenience. The boombox gives action sports and outdoor enthusiasts 18 hours of nonstop music. Whether you're at the beach, shooting rapids, or hiking outdoors, the boombox remains safe in its tough (Pelican-like) weatherproof shell.
How I Came Up With The Design:
It's been a while since I last posted my last boombox tutorial, it was pretty much a success but as we all know technology advances annually. RaveBOX is now as powerful as my old boombox but it's half the size of the old one.
I really had no design when I made this project, I had a "go with the flow" sort of vibe. One day I went to the mall to buy my usual supplies then suddenly I came across this generic Pelican-like case. They were selling it for like P480 ($9.60), I still had some speaker lying around, so I thought it would be cool to fit my four unused fullrange speakers + my 4" HiFi woofer. With no hesitation, I bought the awesome looking case. As I went back home, I started searching for parts in my inventory. I still had some amp chips lying around. I found two extra 2x3 Amp Modules (form dx.com) and my beloved Bluetooth Player Module (from dx.com).
All that's left is my battery, I wanted to make sure that my boombox would last a day of non-stop playback without charging, so I though of a solution! My robots are using LiPo batteries since they had a high "size to power" ratio, meaning they have a high mAh rating for their extremely compact size. Since the competition is still scheduled for December, I borrowed some of my LiPo batteries and decided to put them in my new speaker project.
- 2.1 Channel Audio System (6W + 6W + 20W)
- USB Charging Capabilities (6600mAh)
- 18hrs Max Playback (LiPo Bat)
- Bluetooth 3.0 Audio Connection
- 3.5 Stereo Auxiliary Connection
- Equipped w/ FM Radio Tuner
- IR Remote Control
WARNING! You'll need some basic soldering skills, a little knowledge of electronics, and some patience to build this. Please don't blame me if you mess up the modules. SMD chips are very sensitive to over-voltage, handle them with extreme care! There's a lot to go wrong with this project. Good luck!
