Picture of DIY Tough Bluetooth Boombox (Lasts 20hrs!)

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 and my beloved Bluetooth Player Module (from

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.

Specs/ Features:
- 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!

You put the charging unit directly to the lipo battery. So you can charge only 12V devices? What's the idea behind that? It would be cool to put a voltage regulator in between, so you can charge phones, psp's and mp3-players...

The charging plug is for the boombox's LiPo charger. If you look at the boombox very closely, the Bluetooth panel has a USB port. You can certainly charge any type of USB device (iPhones, PSPs, etc...).

So for the pcb amplifier ?

tiagos6 months ago

If my bigger speaker got 3" instead of 4" does it change many things in the pcb amplifier Thank you!

QAZW tiagos20 hours ago

no, just make sure your speaker can sustain the output wattage of the amp

we can make more powerful speakers
and we can connect a jack for electric guitar
excuse me for the lack of spelling I do not speak much English

what is the total price when we bought everything

I tried making the TDA2005 mono amp, but I couldn't get it to work. I tried twice. I made sure that my PCB doesn't have any short. I followed all parts, except that I got the TDA2005R ( not TDA2005M ). I am not sure if this was the culprit. And man, did the IC heat up. I was using a 13v, 4A power supply.

Any help would be appreciated.


Well if you haven't already put a heatsink! Cause otherwise that amp will screwed in no one from the heat :)

wait. don't you have to use a balanced charger with a lipo? in the wiring diagram you don't have one... only a dc charging jack? does this mean you don't need one...

ASCAS (author)  Divergence1 month ago

I already had stated that in step# 12. I guess you already know where to hook it up. :)

Oh yeh my bad haha

where do you get the 2.2 uf 25v capacitors?

also where do you get the 100 nf 25v capacitors?

you can buy them from any electronics store, in australia i use jay car or altronics, try radioshack in america

thanks mate

Or they're cheap as on eBay or :)

There is nothing wrong of surface mounting thru hole compoments on the copper side.

What's te use of using 4 tweeters?

They're not tweeters they're full range

Great instructables man! Just wondering if this is a more expensive project than the Bluetooth speaker you made a couple of instructables ago and what are the advantages to this one? Other than being able to charge, use SD or fm

What capacitor did you use on those PAM amps

Hello. Awesome setup! Do you have an update and precise parts list?? Much appreciated!


ASCAS (author)  george.winstong2 months ago

Thanks. I showed pretty much everything in Step#1. If you're looking for a different BT speaker project, I'm working on a 3D printed version. Probably I would be finished by the last week of December then publish the guide on January.

Yes I would be interested! However, for now I want to build something for someone for christmas. I'll try with what you have and then build another with your updated version. thanks!

How Much does it cost to make this and if possible could you make one for me in black? Also how good are the speakers?

at step 7 what resistor you solder on the module, is in the first picture of step 7. thanks

ASCAS (author)  nneracher9 months ago

It's a 470uF capacitor for filtering the line. It's done to prevent the buzzing sound.

470uF at what voltage?

HI !

Just on question why 2 HP per side ? what does it change if i only take 1 amp

where i put left n right Using this way only 2 HP

Where can I get the materials needed in order to make my own board?

I noticed that when you installed the components for the mono amp you soldered it on the copper side, clearly you have no technical education, whatsoever. Who puts all of the components and solders it directly to the copper side of the board? ask any technically inclined person and they will tell you that it's wrong. As a general rule in electronics all of the components are ALWAYS on the top or blank side, that's why it is called the components side and whats ALWAYS under neath it is the copper side which is called the solder side. Please observe general safety rules in electronics and leave the technical stuff to the professionals or technically inclined. You do not know the hazards you are imposing.

Alternative #2 and #3 for the woofer is the same.
Also, most of the tweeters in the link are no longer in stock. Any alternatives?

Will I be able to just use an actual Pelican case without any issues or just get a case as close as the one you used here? The link you have in this Instructable works, but I can't order from that site.

cool! are you from the philippines ?

ASCAS (author)  jay-vee hacker9 months ago

Yes! why?
