Can someone please help me understand this circuit diagram. (see attachment).

Ok I stumbled across this on some random site a few weeks ago and thought I'd have to post it here some time for a bit of fun. Seriously though, it does kind of remind you of every really badly drawn circuit diagram that you've ever seen doesn't it.

Haha Happy Easter

Come ON!

If you can't even understand something this basic, you don't deserve to be here. GTHO our internets.

I was just looking at that schematic at work last week.

I thought we had IP on that?

Must be a leak somewhere!
