What an odd picture. Not sure why you didn't link to a real source. This seems to have a similar looking circuit board:

But then this article has a completely different picture:

If it was really mounted in that case in your picture, it's indeed a little funny looking. I mean, all of this politically correct rage is misplaced if the fucking thing actually did look like a bomb. You gotta know that's not something to take into a school...

And who "invents" a clock anyway? It's sort of already-done. I mean, 50 years ago kids were putting together AM radios with electronic kits. At least that's sort-of interesting. It picks up signals from a 1000 miles away--cool! I mean, a clock? Why not invent an inclined plane next?

Oh, well. The media needs to push its narrative.
