Simple Amp iPod Amplifier
O'Reilly's Make Magazine has a great DIY community at Instructables.com where people post photos and steps for a wide variety of how-to projects. A recent post over at Gizmodo reminded me of one of my early favorites, posted back in April 2005. The project is a small amplifier for iPods and other portable players, designed to sit between the headphone jack and a speaker system of some kind. Steps walk you through acquiring the parts from Radio Shack and Velleman, includes some shots of testing out the project and a shot of the finished assembly. Ideally you want to download the manual from Velleman to help with building the project, which isn't entirely clear from the Instructables photo series.
