Thanks! I was curious about this, because having volunteered for FIRST robotics, I can tell you that the number of HS students in the US with the skills to design and build a digital clock is pretty much 0. Looking at the picture, I think that maybe he re-homed a commercial clock into a different case and added some leads to run it off a battery ... which is still beyond the capabilities of 99% of US HS students. Either way, congrats to Mohamed for being curious about how things work, shame on his teachers for not doing due diligence (maybe asking the electronics teacher to take a look before calling the police?), and I wish there were more information available about exactly what Mohamed had done, because I find that to be the interesting part of the story. Not that the response was appropriate, but I'm pretty sure that if I'd taken a similarly looking device into my very WASP-y suburban school, even though I'm white as a sheet, my school administration would have had a similar response. People are really paranoid these days, and right or wrong, we all have to deal with it.
