How to make a hidden entrance inside a home/base/etc that uses no visible redstone, buttons, levers, and pressure plates.
How this works: When the furnace is smelting, it causes a block update which triggers the block update detector. The detector used is the classic “T-BUD” or toggle BUD which can be found on the wiki. (http://www.minecraftwiki.net/wiki/Tutorials/Block_update_detector)
