Launched over 10 years ago, the Squeezebox was one of the most popular network streaming devices sold. The idea was simple: put some MP3s on a computer, connect the Squeezebox to a LAN, and stream those tunes. Someone at Logitech had the brilliant idea that MP3s and other audio files should be stored in an online service a while back, something that didn’t sit well with [Richard]. He went out and built his own Squeezebox with a Raspberry Pi, out of an ammo box, no less.
Most of the project is based on another Squeezebox Raspi mashup over at Instructables. This was a wall-mounted project, and not encased that keeps 7.62 ammunition secure during transport. It did, however, provide enough information for [Richard] to use in his project.
To make his Squeezebox look a little more industrial and sturdy, he cut a few holes in a NATO ammo can for speakers, a TFT touchscreen display, and a USB charger port. Inside, a pair of powered speakers, a USB hub, and a powerbank were added, making this a portable streaming solution that can take a beating.
[Brandon Fiquett] does a lot of amateur radio communications and needed a rugged portable power supply that he could take with him on the road. He decided to make a 12V power supply out of an antique ammo can he found at an army surplus store.
The .50 cal ammo box wasn’t in the greatest condition when he picked it up, so he completely sanded it, re-painted it, and lubricated the rubber seal. Inside, he loaded it with four 7.1Ah sealed lead acid batteries, complete with 12V cigarette fused sockets, banana plug jacks, a 5V USB charger and an integrated 12V lead-acid battery charger. The lid also features an LED strip light, and everything is laid out very nicely inside of the box. It looks great, but [Brandon] has a long list of improvements to add, including a solar charge controller, volt and amp meters, and an LED power switch.
Ammo cans make solid project boxes. We’ve seen countless ammo can speaker setups, and even a more intricate ammo can PSU — though we prefer [Brandon’s] method since all the connections are under the lid, keeping it completely weather proof.
