You think that is easy?
Edit: and what about for parents who don't have the resources or ability to manage that kind of control? My point is that it's not easy, not even in the slightest.
If they’re super young, they’ll entertain without electronics. Give them a coloring book.
If they’re a little older, tell them to go use that Snap Circuits kit. Or here’s a ZX Spectrum and a manual on z80 asm. Or here’s a Nintendo DS and a Pokemon game.
