Sure, there's plenty of hackery going on with interactive whiteboards these days, but that doesn't mean plain old marker-based boards have been left out of the fun completely, as evidenced by this latest contraption devised by Sprite_tm. As you can see in the video after the break, he's managed to rig up a slightly precarious system that'll write out any message you send it over the web, and with surprising legibility no less. To do that, Sprite salvaged some parts from an old scanner and printer, along with an ever useful microcontroller, an x/y stepper system, and some rather clever touches like an electromagnet to keep the marker on the board. He even bravely opened up the board to the public, although that unsurprisingly doesn't appear to have lasted very long. If you want to give one a shot yourself, however, you can find most of the details you'll need and the necessary source code by hitting up the read link below.

We've already seen one hack to automate Guitar Hero, but it had the slight disadvantage of having to be pre-programmed for each song, and even then it was slightly hit-and-miss. Now, a father looking for a way to finally beat his son at the game has taken things considerably further, with his hack actually using the composite video input to determine which notes need to be hit in real time. That, as you might have guessed, is way beyond any notion of practicality, and far outside the realm of the average DIYer's skill level, but it seems like it does indeed work, although there are apparently a few minor kinks left to be worked out. If you're still not undaunted, you can find the schematics and other information you'll need at the link below, and check out a video of the setup in action after the break.
