Gadget freak. Gearhead. Early adopter. Computer nerd. Propeller head. Whatever term you prefer, chances are you know at least one: someone who thinks nothing of hooking up a coffeemaker to her home-computer network or tinkering with his own flux capacitor. So if an orange and two boxes of Chiclets are way too analog for you or your favorite technology fanatic, these inexpensive high-tech stocking stuffers are to sure satisfy.

For a geek on the go, nothing says sexy mobile computing like a flash memory device for transporting data. Don’t worry; the iRock MP3 player ($59.97) from your local RadioShack won’t reveal its privates unless you take it apart. The iRock uses SmartMedia memory cards (64MB/$39.99, 128MB/$69) to store up to 192MB of music (that’s approximately 3.5 hours of Devo) downloaded from your Windows-compatible PC via USB connection. And you can record your own ramblings with the Digital Voice Recorder with Super Directional Microphone ($89). It can record up to 90 minutes of audio in long-play mode, and even download recorded audio files to your Windows PC via USB.

During the holidays, gadget freaks like to get their drink on, too, and what better way to become master of ceremonies than with the Bar Master ($29.95) from the Sharper Image? This PDA-size gadget comes in an oh-so-hip flask shape and contains a database of 500 popular drink recipes, searchable by name, category, ingredients, alcohol type, or occasion. The database even includes mixing tricks and terms and tips for setting up your own bar. When the evening reaches its inevitable lampshade denouement, blow into the Digital Alcohol Breath Tester ($99.95) to see how geeky you’ve become. The tester sounds an alert if you register a blood-alcohol content of .05 percent or higher and comes with two reusable mouthpieces.

The Ghost of Technology Past would appreciate the Atari Classic TV Games Controller ($24.99), available at the Electronics Boutique. Go way retro with this Atari 2600 joystick that attaches to a TV via an RCA jack and contains 10 classic Atari video games, including Adventure, Real Sports Volleyball, Gravitar, Video Olympics, Circus Atari, Yar’s Revenge, Asteroids, Centipede, Breakout, and Missile Command. Parachute pants and painter cap are not included.

Finally, you can’t forget stocking stuffers for those carbon-based geeks-in-training we also like to call " kids. " It’s never too early to get them pointed in the right direction, and the KidzMouse line of children’s mice ($19.99) will help. Both Mac and PC compatible, the mice come in three characters — MollyMouse, CoolBug, and BenjieBee. If junior doesn’t have the opposable-thumb thing down yet, no worries; the KidzMouse is designed for smaller hands and activates computer action when the mouse’s head is squeezed. They’re available at Microcenter and online at www.kidzmouse.com.
