SethBling has been creating pure insanity in redstone form for years. It's honestly stunning that he can keep coming up with crazy new contraptions with such speed, to say nothing of how long he has been doing it. Today's tutorial video is no exception - a contraption that acts as a counter for dropped items!
There are obvious applications - a toll booth, a monster-proof locking system, or just a clever, reasonably simple-to-create score-keeping system. The best part of this contraption is that SethBling explains how to create one in detail, covering how it works, what parts to use, and some interesting uses for it. Neat!
Have you built this yet? Does it work?
