This is a great DIY idea! If you have a cool enclosure laying around and a little knowledge on basic electronics, you can create a cool looking speaker system that you can take with you anywhere!
The Podzuma was a direct result of a need for a great sounding portable speaker system, that could be connected to any music player. This is a speaker that plays loud enough and long enough to be used outdoors at a family reunion, ball practice or the pool. The main goal of the project was overall portability but also quality of sound and battery runtime.
The fidelity is very good, and this speaker does a good job at projecting and maintaining clarity at long distances. The bass is respectable-it doesn't play extremely low, but the bass that is there, is very solid and punchy. If placed near a wall boundary, the bass performance can be downright impressive. At a barbecue, the park, or the pool, we don't think it can be beat by any other product available on the market!
In the other side of the scale, for $39.99 you can buy this DIY kit to make a tiny boombox. The Bird-Electron EZ17-B iPod Recycling Speaker, is a kind of homemade looking solution. The panel contains two speakers and fits exactly into the top of the plastic box which once contained your iPod (1G and 2G Nano, 2G and 3G Shuffle). The passive speakers are driven by the power from the headphone jack, so don't expect to rock a party. Kudos for the recycling aspect This is clearly a step up from the traditional hacker's enclosure, the Altoids tin.
And who could forget about the Solar Powered Boombox? That way you don't have to deal with batteries or AC plug!
