Many computer games ask a lot of your mouse finger. There’s only so much rapid-fire clicking you can do on your own. If you find yourself with an aching finger, this DIY rapid-fire mouse button hack might be just the thing.
The folks at MAKE put together this hack by connecting a 555 timer circuit to the terminals of the left mouse button. The circuit lets you click up to 800 times per minute. Now, we’re not at all advocating cheating, at least not in online games with actual people. Not only is it wrong, but competitive games often have code that look for click patterns like this and will give you the boot. Besides, in those types of games, rapid-fire is just as likely to get you killed as not. But for single player games where you have to click a lot, like say Torchlight 2, rapid-fire clicking can save you some aches and pains.
