When you think of Memorial Day weekend, what comes to mind? Well around here, all we can think about is this tank cum boombox that Instructable user [Elian_gonzalez] put together.
This build is actually the third version of his Music Tank, and it comes with all sorts of improvements over previous models. The tank is primarily constructed out of plywood, with cavernous compartments for holding all of its goodies. In its capacious body, the tank sports a 60 Watt stereo system that powers a pair of external speakers mounted on either side of the turret. The turret itself contains an air-powered cannon built from PVC tubing, which we imagine can be used to shoot a multitude of different projectiles.
While the concept itself is pretty cool, the tank happens to be nearly self-sustaining as well. The tank has a pretty deep battery well and uses a 50w home made solar panel to help keep things topped off while in use. [Elian] does not specify a total running time, but we imagine that it can go for hours on a nice, sunny day.
