What robotic PC add-on would instructables users most want to build? Answered
I'm interested in building a PC add-on, and posting it on instructables. Now, the type of thing that I'm talking about would be like a simple robotic arm to automatically reload the DVD-writer for mass production, or a customized USB game controller, or a wriggling USB squid-monster that quotes you Shakespeare in a computer voice, or something. But, none of the above, since they've all been done.
What does your computer need to do for you, that it can't do now?
