If they suspected even for a short time that it was a bomb surely they would/should have put the emergency procedures into action and evacuated the school, etc?

He definitely did not "create" anything here, I agree that he re-packaged a clock.
The circuit board is all the evidence you need. He did not make his own cheap "Chinese" PCB and solder mask it. And the ribbon cable to the display, no, this was some clock to be seen from far away.
Who would make a clock for demonstration with a wall transformer attached like that? A hobbyist would have used a large battery pack.
He's just a kid with a really basic understanding of electronics.
Now what I have a problem with is "lowering the bar" for "creating" something by just re-packaging an existing item. It reduces engineering to, well... just stuffing some crap in a new box.

Well this is pretty much how I started as a kid.
We didn't have a lot to entertain ourselves with, and I was fascinated by 'how stuff works'. I started by taking stuff apart, but it was when I started being able to put stuff back together again and get it to work that the fun really started.
I used to 're-build' transistor radios and put them in different enclosures, for example, and I had motors and gear trains doing all kinds of stuff, maybe not 'useful' stuff, but still fun.
From 'his point of view', he's turned a pencil case into a clock......probably the first project he's actually 'got to work'.........We all started somewhere.

Ash, that's not my point.
Yes we all started out this way. I was taking everything apart at 5 yrs. old, and it was a problem for my parents.
My point is, I wasn't "creating" anything. ("Creating" meaning constructing something from basic elements to make a finished good.)
He is trying to lean how things work, and that is fine.
The article is not written properly to reflect what he did, and that is what my point was.
If he had a breadboard with 7400 logic, and a bunch of wires everywhere, and a battery pack, and it looked like a rats-nest, then he would have "created" a clock. (this is my point)

I made something like this when at secondary school, it was along the same lines (recased clock with Fresnel lens to magnify the LCD) Worked quite well until some phool dropped it.

Well, When you haven't developed the skill yet, take something you are interested in and make your own container--perhaps re-arranging the face and using better 'buttons'. In reality--if you don't do this with a certain degree of care and proper handling: Nothing lights up when you flip it on!! The thrill of success at this (first) point in his hands-on field of interest can be quite encouraging only leading to the next more advanced steps. AND...remember, if it does not work after this natural first step (a REAL possibility!), determination will make a future engineer try again or seek help--perhaps discovering a grounding fault in the new case (the most probable cause of zero operation IMHO). ...and a great first obsticale to encounter and overcome with just a jumper wire! Anyway, unless he just gives it all up and throws it in the trash (NOT an engineer's attitude), he WILL succeed! (hoping he overcomes this ordeal) There can be great encouragement in displaying a working device in which you simply successfully transplanted He certainly won't repeatedly gut and recase!

Random relevant bits;
The guys that take existing stuff, shuffle it around and re-package it in general earn much more than the guys that designed the original stuff so don't knock it !
(I was part of a design team for an automotive project that took about one year, the designer of the logo on the product got 2-team-years income ! )
I used to be in industry, then research, then back to industry, there is enough technology available for a wonderful world there is little glamour or reward for actually producing stuff it is time that rewards went to the makers/growers/workers.
(now I'm stuffed ! not only electronics and chemistry hobbies, a muslim-convert socialist too ! if you don't hear from me for a while please forward my emails to Guantanamo
While I was off work sick, one of my colleagues was 'modifying' a battery pack into a box, another colleague came across the box, didn't know what it was, and reported it. ..... The fire brigade were certain that it was an explosive device so allowed my colleague to carry it out to the car park !!!!!!!
