There's no new evidence here - it was obvious the instant we saw the photo of his project that he'd repackaged the guts of some old AC clock! Good for you that you figured out exactly which one it was, but really, so what? I worked on similar projects when I was his age. You have to start somewhere, and casemodding a piece of old garage-sale junk is a totally reasonable project for a 14-year-old newbie.
We aren't making a fuss over him because he's an extraordinary genius; rather, we're making a fuss over him because he's just an ordinary kid who *ought* to have been treated with ordinary respect, and we're trying to make up for the unforgivably shitty dumbass bullshit he's been subjected to.
And really, it's less about him than it is about all the other kids like him: the message is "don't let those fucknuts in Texas scare you, smart young Muslim inventor kids; America at large thinks you're cool".
