Not knowing much about electronic circuit boards (I’ve seen them outside cases) but the one the kid built (supposedly) could not have been done by him. The board depicted is too professional looking. I suppose he could have bought all the parts and circuit board over the internet.
You can easily read that the circuit board has been identified as belonging to a specific clock sold by Radio shack in 1986. It was not a kit.

Yes, google "digital clock kit".
Someone posted the reverse engineering how-to.
It’s a 1970s Radio Shack alarm clock. Literally anyone could do what he did and it took no knowledge of electronics.
