ShaBOOM is a boom box that I designed to work with any mp3 player or any device that uses earphones.
As a big bonus there also is a Power Bank of 16.2V that can be used to charge ANYTHING that requires a USB 5V 2A source to charge. It will charge your cellphone and still charge a couple of other small devices. The Power Bank is totally separate from the 10W Audio Amplifier which will run hours on it's own power source of 16.2V. A total of eight 18650 Samsung Lithium batteries are used. Four batteries on each side. The whole unit is only 3lbs and all parts were created on my modified Thing-O-Matic 3D printer and modified Shapeoko 2 CNC machine. And best of all.........the whole unit is rechargeable via the Tenergy Smart charger. You never have to open it and change batteries.
I've included all the part files and documentation.
Make one of your own ! :=}
