    Eee PC School: Add a Keyboard Backlight For Under $15

    By Posted on 5.22.2008 11 Comments

    As we showed you in our May 2008 issue, Asus's Eee PC has quickly become a favorite of hardware hackers around the web. Here, we offer the first installment of our Eee PC School series. Check back in the coming weeks for more tiny ultraportable tweaking.—Eds. What good is that portable PC if you can’t type anywhere and anytime? With its ultra-compact keyboard, even touch typing pros will be hard-pressed to avoid frequent mistakes on when the lights go out. To say it’s a frustrating exercise in futility to locate the miniature F3 key in the dark is an understatement. Oops, you just lost WiFi contact by accidentally hitting F2.

    I like the idea of an even light provided by the EL strip -- while it also shines between keys it appears to illuminate the backs of the keys fairly well on a white Eee. But the inverter, batteries, and switch hanging off the back are really kludgy. A mod at http://forum.eeeuser.com/viewtopic.php?id=3735 has an elegant solution for controlling an led hacked into the bezel to light the keyboard. He tapped into the system i2c bus and used an i2c io expander chip (for which there exists a Linux driver) to drive the LED. With a short script to toggle the LED and a hotkey that runs the script, it's a really slick setup. I think the best soution would be to use a piece of sanded plexiglass under the keyboard to act as a diffuser. Light it with LEDs and use the method above to rig a hotkey for it, and it'd be as good as the light on a macbook pro.
