Project Description:

Battery powered Sprit in a can. Bluetooth capable.

Tips & Tricks:
You can use a 1.25″ PVC 90 deg. elbow to get the port length right. The LED holders, switches, and inputs are not intended to pass through .25″ MDF. If I didn’t have some esoteric tool for working sheet metal on big jets I would have had to tear the lining back out as I had already Gorilla Glued it to the inside of the can before I got the accessories for the project. Don’t use printed panel MDF cause glue doesn’t stick to it well. It was the only stuff I could find that day I was looking for it. Had to scuff sand everything that was glued to it.
Take picture while Building!

Conclusion:

This thing sounds great! I cobbled together an ammo can boom box without Bluetooth and while it played only through an Aux In Jack I was looking for something just a bit more portable and of course something with a shall we say design. After Searching Boom Boxes I stumbled upon the Sprite Stuffed it in to a can!
