Micro-SD Card Slot Abused As VGA-Port

Posted by Soulskill on from the hack-it-till-it-fits dept.

dvdkhlng writes "The Ben NanoNote open-source hand-held computer has often been criticized for not being very extensible hardware-wise. A community effort now starts to challenge this by shipping the so-called UBB board, which plugs into the micro-SD port, making 6 I/O lines available to hardware hackers. The most impressive use so far is this VGA port implemented by just a few resistors, with signal-generation mostly controlled by software. The guy who did this calls it an 'unexpected capability.' Schematics and source code are available under the GPL."

    For one it's fun. It's OK to have fun. If we only do those things that need to have a (serious) reason, we'd never have any fun. You must have gone straight from diapers to curmudgeon, without the usual goofy and fun states.

    For another, this would be great for a low-cost embedded project. I can easily see this being adapted to an embedded playroom I play with.

    Lastly, ti's cool.
