Please download although it says 60%! Hi, i'm here with some of my own original work with redstone, i will give credit to the guy who came up with the t-flop that is really compact, thanks dude. Also, i have seen a few other hidden lavaplace things, but mine is a bit different. Mine has some pistons in the back, behind the lava flow to keep any curious players with diamond armor or something out, so they presume it is just a lavaplace. Also, most of the logic gates such as the X-OR gate i did not design, or the AND gate. But the keypad idea is completely mine. To answer a few questions:

1. "How come on the hoe activated entrance the piston below the top keeps disappearing?" Well, that is just a glitch with minecraft, sometimes the pistons fail and disappear, same with the hidden lavaplace.
2. "Why did you include a rating?" Well, they are just my personal ratings about how i think the device is.
3. "How long did it take you to make such a flat land?" About 1 minute, using WorldEdit for spc (Single Player Commands).
4. "Why does the counter have such a delay as it goes?" Well, that is just because of the repeaters, i may upload another version of this using Djoslin's Instawire mod.

This map will receive updates as i learn how to make new devices. I will comment if it is updated and on what date it was.

Yes, i know that i led you to the bukkit site for worldedit, but there is a way to implement it into single player commands, i think he says how to on the page.
