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.
