Here’s the scenario: You have a thousand MP3 music files sitting on your home computer—which is great when you’re actually sitting at your computer but a lot less useful when you’re in the kitchen or living room. What you need is a dedicated device in another room that can pull songs wirelessly from your PC’s music library and play them through its own speakers. Several off-the-shelf products can handle this task, such as Logitech’s Squeezebox; unfortunately, they start at around $300.
But you can build your own remote-control wireless streamer for less than a hundred bucks using just about any old Windows computer (if you don’t have one gathering dust in the closet, ask your office’s IT department or search around on eBay). You can buy or make a custom enclosure that matches the room’s decor and add a small LCD screen to show you what song is playing. Then throw in a wireless remote control, and start streaming your favorite tunes anytime—and anywhere—you want.
