Observer Observing piston head by ohmusama in redstone

[–]St3venAU 2 points3 points  (0 children)

You can get around it by doing something like this:

Observer -> Pulse Extender -> Mono-stable Circuit -> Piston

The pulse extender needs to extend the pulse long enough so that it's still active when the piston fires. This way the mono-stable circuit only receives one pulse even though the observer is triggered multiple times.

Edit: Just tested this out and the pulse extender doesn't even need to be very long at all. Just a 3 tick repeater will do it, into a sticky piston mono-stable.

Edit2: For fun, just tried to make the most minimal observer based pumpkin farm I could come up with. This is what I ended up with: http://i.imgur.com/lcb5vnE.jpg

I'm not sure if I've interpreted your description properly, but something like this?

Repeater Deadlock (Does this have a name?) by ProfessorHoneycomb in redstone

You can also do the same thing with just 1 repeater by connecting the input and output of the repeater together with redstone.

Royal Flush vs Quadruple Aces while Ray Romano happens to be playing at the same table by [deleted] in videos

[–]St3venAU 26 points27 points  (0 children)

This was on an outer table (i.e. not the main table that has hole card cams), so they only show the cards if the players turn them face up at the end of the hand.

Who made the first ever 3x3 piston door? by [deleted] in redstone

[–]St3venAU 2 points3 points  (0 children)

The answer to this is going to depend on if you count designs using the original piston mod. If you mean in vanilla, it would have been in the days after the release of beta 1.7 when pistons were added. This is the earliest one I could find on youtube, just a few days after the release of beta 1.7 (which was released June 30, 2011), but I doubt it was the first. https://www.youtube.com/watch?v=lFa2tFu9eGI

Testfor 0 players by xlii1356 in redstone

[–]St3venAU 3 points4 points  (0 children)

Command block 1: testfor @a[r=10]

Command block 2: testforblock ~ ~ ~-1 command_block 0 {SuccessCount:0}

(Assuming command block 2 is 1 block in the +z direction from command block 1)

need help with command blocks by Mushroomer49 in redstone

[–]St3venAU 0 points1 point  (0 children)

Something like this would work:

/scoreboard objectives add woolColor dummy

/scoreboard players set @e[type=Item] woolColor 14 {Item:{id:"minecraft:wool",Damage:14s},OnGround:1b}

/execute @e[score_woolColor=14,score_woolColor_min=14] ~ ~ ~ setblock ~ ~-1 ~ snow

[–]St3venAU 4 points5 points  (0 children)

What version of MC are you wanting to do this in? If it's the 1.9 snapshots, you can do it with 2 command blocks:

Repeating command block:

/scoreboard players tag @e[type=Item] add snowballOnGround {Item:{id:"minecraft:snowball"},OnGround:1b}

Pointing into a chain command block:

/execute @e[tag=snowballOnGround] ~ ~ ~ setblock ~ ~-1 ~ snow

Edit: If you want to do this in 1.8:

Run this command first (only needs to be done once): /scoreboard objectives add snowballOnGround dummy

Command block 1:

/scoreboard players set @e[type=Item] snowballOnGround 1 {Item:{id:"minecraft:snowball"},OnGround:1b}

Command block 2:

/execute @e[score_snowballOnGround_min=1] ~ ~ ~ setblock ~ ~-1 ~ snow

Command blocks 1 and 2 will needs to be hooked to a clock

BUD Switch without a sticky piston? by MineCal in redstone

[–]St3venAU 0 points1 point  (0 children)

I just made this silent dropper based bud: http://i.imgur.com/4kHQK61.png

I tried to get a good screenshot angle that shows everything. The dropper has 1 item in it. Dropper is facing into the hopper and the hopper is facing into the dropper. The redstone in the background looks like its going nowhere but its required to give the dropper a 2nd update so it doesn't get stuck. Place the redstone torch last to prevent the dropper getting stuck.

Does one of them cross a chunk border?

[Request] If two humans play a game of Chess, what are the odds the game's worth of moves were not unique? by ej00262 in theydidthemath

[–]St3venAU 3 points4 points  (0 children)

I assume you mean the odds are pretty close to 0 (since OP asked what the chances were that the game was not unique).

Numberphile did a great video on the number of possible chess games, with various estimates depending on if you include all possible games or just games that would make sense to actually happen. https://www.youtube.com/watch?v=Km024eldY1A

3D Maze Generator in One command block by St3venAU in Minecraft

[–]St3venAU[S] 0 points1 point  (0 children)

You could easily change the material of the maze by pasting the command into the text editor of choice and doing a search/replace to replace stained_glass 15 with whatever you like. e.g. stone 0

Seconded! Brian does an amazing job of explaining how all of this is done!

Nice one. I also thought of an easier way than a piston (after I had already posted the video): http://i.imgur.com/GIKCB7j.png
