How to Build a 9v Battery Powered USB Charger

The original article located here has been removed due to issues with the design. As someone pointed out in the comments, the 7805 regulator regulates voltage by dissipating the rest of the energy as heat, which means that if used for extened periods of time the regulator will get very hot. This doesn’t happen right away, and it will charge your device, which is why I didn’t notice it when I first did the tutorial. Running a ~600mA external hard drive off the system however made the regulator hot to the touch after about 10 minutes. Therefor I wouldn’t suggest anyone using this I’ve left the original technical explenation comment for anyone who wants to check out the technical reasons themselves.

Speakers Hacked into a Little Black Back Pack

backpackspeakers1 Speakers Hacked into a Little Black Back Pack

Portable speakers can be very nice little accessories to carry around, but the “little” part often extends to the sound as well. Forum member Dobson did his own thing and instead put speakers in a backpack.

Dubbed the “sound bag” by its creator, this thing is quite impressive with 2 large speakers powered by a 50W amplifier that runs off a 7000mAh battery, which gives the rig a battery life of about 15-20 hours. This will definitely play louder than anything even an army of normal portable speakers can spit out and might not be too bus-friendly, but it definitely has style. Great work!

Giant Creative Zen Stone Crafted From Wood

wooden zen stone Giant Creative Zen Stone Crafted From Wood

One of our forum moderators, Captain Ødegård, is quite crafty when it comes to woodworking. He claims he has more wood tools than I have MP3 players, but one of these days we will have to settle the score.

Honed out of pine and burned with a hot knife– his latest creation is a giant Creative Zen Stone measures 8.25 x 5.5 x 2 inches. The internal components aren’t the real Zen components since the Stone is relatively expensive in Norway. However, this wooded Stone still does pack in 4 times the memory with 4GB of memory stored on an SD memory card.
