From the beginning I smelled a rat ... but I'm pretty cynical.
He didn't "invent" or even "make" a clock ... there's no Ardoino or RaspberryPI note even so much as a Heath Kit (do they still make those?)... he didn't make any circuit boards or stitch together parts bought at Radio Shack.
All he did is take the guts out of an old digital clock and put them in a box (I believe purposely making it look like a bomb).
Here and engineer reverse engineers his "invention". http://blogs.artvoice.com/techvoice/...and-ourselves/
My suspicion is that he did this knowing it would be blown out of proportion (no pun intended) and it could be capitalized on by his or his fathers' friends at CAIR.
