"Tech Upgrades" is for anyone who's ever wished they could build their own touchscreen, brew up and use conductive ink, rig a mouse that you can operate with your feet, or make a rad engraved computer tower that glows in the dark--essentially, it's for fun-loving nerds everywhere. Used to be, whenever you had a computer problem or techie glitch, you went and found the nearest geek to help fix it. But now, there's a new movement afoot--a band of inventive and self-reliant geeks who hack computer and software to solve problems (and, in some cases, just to have fun). From building your own computer out of a cereal box to modifying safety goggles to see infrared rays, from skinning your laptop with steampunk trimmings to divising a foxhole radio, and from setting up a projector for your iPhone to working out with a dumbbell of old CDs, this book makes being a nerd, well. Cool.
