I understand that. However, take a look at it: it’s the guts of a cheap digital clock, with no apparent modifications. It doesn’t even have the 9v backup battery connected; i.e., it can only operate when plugged into the wall.
There is nothing resembling a blasting cap or detonator, and nothing resembling an explosive. No stray wires leading anywhere suspicious. It looks like what it turned out to be: the guts of a digital clock stuck into a case.
The point is the swap over to battery power is near trivial, and as I said most clock chips have alarm functions built in that could be used for most any kind of event trigger (buzzer, bell, etc. after proper conditioning).
When you’re learning or in training/practicing, you don’t do it with explosives installed.
There is just too much crap there for “just a clock.” For it to be “just a digital clock” it would have to be the technology like back when I was working on electronic equipment in the 70s.

Well you got close to answering my question. So the only thing missing is the explosive and the detonator. Now which wire’s could be used to set off the detonator?
