Fast Flush Linear Hidden Floor Staircase

lol, what a title

Have you ever wanted a clean and easy hidden staircase in a large open area? Do you hate having to jump because there are no stairs in the one you already have? Then this is the thing for you!

This device has a neat feature where you do not require to copy the air blocks in mcedit. That makes it much easier to incorporate into existing builds. Because of this, the active blocks are easily identifiable (unless your floor is made of sandstone).

Also, the only input is the redstone dust highlighted in image "Info". As long as that redstone is powered, the staircase is open.

Once you have it in your world you just need to replace the sandstone blocks with whatever building material you choose (make sure the floor is full blocks, because it needs to carry a redstone signal).

If you're interested in building it yourself, then here is a parts list:

instead of the glass and the torch just leave air

at least 90 of your preferred building material (84 for the Redstone, 6 for the staircase) + 3 stairs

1 Regular piston
17 Sticky pistons
30 Redstone dust
18 Redstone torches
16 Repeaters
2 Comparators
1 Redstone block
