[Danman1453] is ready to face the rest of his summer thanks to this toolbox boombox he built for outside use. It’s always nice to have some tunes when laboring at those not-so-fun jobs (we’ve got some windows that need re-glazing and you can bet we’re not doing that in silence). But if you can’t really hear it what’s the point? The highest volume [Danman1453] could get out of the consumer options he tried just wasn’t cutting it, and that led him to this project.
The only thing he bought to complete the boombox was some black spray paint. He already had an old toolbox for the enclosure, a head unit and the larger speakers from an old car, and the small speakers came from a set of computer speakers. Those are cleverly mounted in the compartments on the lid of the toolbox, pointed down so that they’re oriented correctly when the lid is propped open. The faceplate was even recycled by using wood an old shipping pallet.
He would like a little bit of advice though. When he’s playing a CD and the bass really gets bumping the head unit tends to skip. Does anyone have an easy method of isolating it from the speakers while still keeping it safe and sound in the portable enclosure?
[Matt Keeter] wanted to take his music on the go, and wrote in to share a great looking boombox he built for under $100. His goal was to put something together that could be made in pretty much any hackerspace/fab lab, so his boombox was made using simple materials.
He first modeled the boombox using cardboard, later fabbing it from wood on a laser cutter. The design allows the stereo to be snapped together, though [Matt] says that some joints were glued as an extra precaution. Inside the boombox resides an custom PCB he built which incorporates an ATmega328, an MP3 decoder, and an SD card to store his music.
One feature we really like is the control scheme [Matt] built into the boombox. Each of the capacitive touch buttons are positioned on top of a copper pad, which are wired into the control board. He says that while good in theory, he had a difficult time getting the buttons to work properly, though they seem to do the job well enough.
If you’re looking for a portable music solution and have access to a laser cutter, be sure to check out [Matt’s] page for schematics and firmware.
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.
[Sam] built himself a boom box using salvaged parts and a car stereo. The case was cut using a CNC router he had access to at his school. The front panel is cut from a “Construction Ahead” road sign. The size of the case is based roughly on the rotting enclosures from which he pulled the speakers. He’s included connectors for external speakers as well as a USB charging port. The unit is powered by a gel battery and is recharged using an automotive battery charger.
A boom box lets you take the party anywhere. We like this one because of the pop art feel of the finished project.
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.
