Humans generate a lot of waste. It is somewhat relieving to see so many great reuses of old items out there on the ‘web. We love covering these types of projects here on Hackaday. [Martin] likes using recycled items in his projects and wrote in to tell us about his recently completed Wooden Ghettoblaster that utilizes a bunch of old parts and doodads he had kicking around.
The main case, believe it or not, is constructed of leftover wood flooring. The fake tape deck, buttons and tuner may look like they are just burnt/etched/stained but they are actually inlaid pieces of darker wood. Once all of the inlays were installed in the front face of the cabinet, the entire surface was sanded smooth and the edges chamfered to add some visual appeal.
Holes for a pair of old aftermarket car speakers were not only cut into the front face of the case, they were also counterbored so the speakers would sit flush with the panel. [Martin] did decide to purchase one component for the project, a set of VU meters. They are mounted to the case via their own inlaid piece of wood and are connected in parallel with the line-level portion of the signal path.

After [Luke] built a suitcase mini-ITX rig for LAN parties he was left with one problem: he didn’t have any speakers and he didn’t want to use headphones. Not wanting to do something boring like a USB-powered speaker setup, he built a PVC Boombox.
Built around 3 inch PVC pipe, the boombox houses an off the shelf 15 W amplifier, bluetooth receiver, and charge controller. [Luke] found a deal on a dozen 1400mAh lithium ion batteries and despite the standard, “if you don’t know what you’re doing, don’t use lithium” trope commonly given as advice, he forged ahead anyway. [Luke] picked up a power converter that charges the batteries and provides some protection. The batteries are charged though wall power with a transformer and a huge cap scrounged from an ATX power supply.
[Luke] is pretty pleased with his boombox. Not only does it put out some decent quality sound, the battery life should be tremendous. It’s not a ground-up build, but we think it’s a pretty nice project. [Luke] will be taking the ‘boomtube’ to the Detroit Maker Faire next month, so if you see him make sure to say hi.
We’re a little confused: [xXxMrCarlosxXx] built an amp out of a cigarette tin and calls it a Mobile Oppression Unit, but we thought all mobile oppression came in the form of giant, invincible crab-shaped palaces. In any case, or more specifically, in a repurposed Lucky Strikes case, he used an mp3 player, some speakers from a garage sale, and a bread board packing an LM1877N-9 chip “optimized for loudness” to construct a great-looking, compact boom box.
