I made a boom box by a wine box, and it's works well. I gave it to my girl friend as a gift. She is so happy that can not help crying... (LoL!)
It's my first DIY stuff, i made it for my girl is real...
Step 1: Find a Wooden Box
Step 2: It's Sounds Good, But Lack of Something
You can see the paper box of my friends, it looks nice but sounds just a little bit stranger.....
Step 3: Find a Amplifier Like This.
I purchase it from taobao, you can buy it from amazon or ebay.
it's a small amplifier，it can be drivered on 5V, and it has left channel, right channel and GND, VCC pins, you can just soldering it with your speaker.
Step 4: Wire It Up
You can find the function description on the amplifier board, such as VCC,GND, L,R (means channel), and you can test it on your laptop.
Step 5: Use Wine Box Instead.
I just find out a wine box and i have drilled two big holes for speakers, and one small hole for the rotate resister on the Amplifier. and wire everything up.
and also,i find a raspberry Pi as music player, burned latest image to the TF card and boot it up, installed a software called "omxplayer" , download some music into my TF card. and write a shell scripts to play music.
sudo apt-get update
sudo apt-get -y install omxplayer
sudo omxplayer -o local xxx.mp3
last command will turn on the music, just enjoy it and have fun.
