Yes. The link was buried in a second link within the original link of the OP at Conservative Treehouse.
I was giving an example of something that an ‘inquisitive’ harmless youth could build for little money. In the end, it was more work to take the clock apart and transition it to a briefcase than it would have been for a “clock kit”.
In any case, with enough battery power, this would have the capability to be made into a bomb.
Yes, if you added batteries, some additional circuitry, a detonator, and explosives, you could convert it to a bomb. I could also convert your digital watch or cellphone to a bomb if I added the same ingredients.
Should we call the police because you have a digital watch or a cellphone? Clearly not. The police should not have been called in this case either. The teacher should have told Ahmed to put his dumb toy away until after school, and that would be that.
