Demo 2: The Idiot Trap

If you're wondering what you could use latches for, here's an example...
The set-up I'll show will do this: if someone goes into the left room and presses the S input button, the iron door closes and the redstone torch in the right room comes on. Someone pressing the R input will then shut the alert torch off and open the door again, releasing the person in the left room.

As with the previous demo, clay blocks are where full walls or floors would go, and white wool is mainly there so the redstone shows up nicely. In this demo, the blue wool represents where another wall would go, so I could show the boundary of the rooms without obscuring the wiring.

I labeled the images this time, so they should hopefully be fairly self-explanatory.
(No errors here, nope...)
A better view of some of the wiring.
There's a mistake here: The vertical "steps" that bring the R input line to ground level will cause a loop if you add in the blocks for the floor, rendering the input nonfunctional. The second step should be one to the right instead of one in front. I might fix the image eventually but not tonight.

And here's the back of the wiring that transfers the signal from the S input.
(If you're wondering why I went with the relatively complicated two-torches set-up here, the answer is that I was working on this way too late at night. It would work just as well with a set-up similar to the wiring from the R input, but with the second wool block one to the left instead of to the right.)
And this is just another alternative view of the wiring. The redstone torch placed along the middle of the inverse output line is placed pretty arbitrarily - it just needs to be somewhere along the line there in order to balance out the torch that's powering the iron door.

The title for this one is pretty much all in how you present it, of course...


For extra credit: add some pistons in the ceiling of the sucker room that are also connected to the inverse output, acting as floodgates and holding back flowing lava until someone presses the button.
