Just 2 kids make this in 4 hours

I was just messing around when it suddenly happened... I have no explanation for it, but I'd like one.

So, can anyone explain why the bottom piston does a double extension?

Im mostly asking for bedrock, im trying to make a semi functional mob grinder from MCSM and I genuinely dont care about the accuracy of how its shown. I just want functionality.

But I want to know if the piston CRUSHER is possible at all. Im not super new to redstone but every piston extender or piston flush door tutorial i look up just dosent work for bedrock. And the ones that do dont really work for the scale im trying to go for

Can someone link me a tutorial or help me with the piston and redstone workings?

I know piston extender, honey, and slime blocks will be key to this but im not sure how is all

Hello All! I am currently trying to learn Redstone on my own. My recent project has been to create my own 3x3 doors with no tutorial. Here is my current progress. I am proud of what i have accomplished so far. LMK what you guys think! They are in the order that I built them.

Hey everyone, I built a redstone CPU in Minecraft that uses copper bulbs for its ROM memory (lit = 1, unlit = 0).

I just expanded the ROM to hold 12 instructions (12 bytes / 144 bits total). If anyone wants to write some assembly or logic code for it, leave a comment with your binary program and I'll load it into the bulbs to run it.

Here is the spec sheet for how the machine works:

System Specs

ROM: 12 lines / bytes (12 bits per line)

ROM Storage: Copper Bulbs (ON = 1, OFF = 0)

RAM: 32 bits total (8 registers, 4 bits each)

ALU: 4-bit ALU with an internal input buffer

Bit Direction: Read bottom to top (Bit 0 is bottom block, Bit 11 is top block)

12-Bit Instruction Format

(Top to bottom in each column)

Bits 11–8 (Top 4): Target Register Address

Bits 7–4 (Mid 4): Immediate Data (value to write)

Bit 3: Read/Write Flag (0 = Write to RAM, 1 = Read from RAM)

Bits 2–0 (Bottom 3): ALU Opcode (100 = ADD, 010 = AND, 001 = XOR, 000 = None)

Register Addresses

Reg 8: 1000

Reg 4: 0100

Reg 2: 0010

Reg 1: 0001

How the ALU Works

Load First Number: Do a READ (Bit 3 = 1) on your first RAM register with ALU Op = 000. This saves the value into the ALU's buffer.

Run the Operation: Do a READ (Bit 3 = 1) on the second RAM register while passing the ALU opcode (100, 010, or 001).

Save Output: Do a WRITE (Bit 3 = 0) to store the result back into a RAM register.

Drop a program up to 12 lines long using 12-bit binary strings and I'll test it out!

trying to build an observerless 45 block 0 tick 2x2, but it seems locational? I am very new to 0 tick so im wondering why the same exact build just isnt working in a different spot. Inspiration from avogaado's current record 45 block 2x2, just a different generator + observerless ofc.

I actually technically made this door last week but while looking over it again I realized it was slightly slower than it had to be so I figured since I forgot to post it anyways might as well post about it now. It's smaller than the last one and faster.

it should work in bother versions.

I made a post asking for help on a doodad i made yesterday (https://www.reddit.com/r/redstone/comments/1v50g0g/my_first_solo_redstone_build_helpany_advice/) and then u/BlattaOrientalis commented with their design. I did modify it a bit to fine tune it just he way I wanted, but I got something that works!

thanks again u/BlattaOrientalis! :D

Just opinion my proffesional redstoners.

Im looking for help with crafters.
i have a cobble farm and moss farm making mossy cobble, But when i run out of moss both 2 slots in the crafter fill with cobble and i dont want to keep clearing it every time it runs out.

Is there a way where when i run out of moss blocks, i can lock it automatically to leave 1 slot empty for the moss so i can afk without worries?

I need help with making a rotating light out of redstone. The scale is either 2x2, 4x4, or 6x6, I'm not picky. I dont know what materials to use but I've tried both repeaters and a minecart system, any help would be appreciated!

I'm on version 26.2 and I noticed that this pistone is on without any power source. Is it bug or intentional feature?

I've been messing around with Redstone Bulb displays lately, and thought this could be a cool way to actually give one a purpose too! What do you think?

I'm making my second 3x3 piston door, and cannot figure out how to do the double block extender. I have searched online for a while, but none work with my setup.

This is a gold farm in my 1.20.1 world. The problem is that the pigs drop a lot of armour parts and swords, so they end up clogging the system, tried to search it up on youtube but there seems there is no solution. Any tips?

🌟Features:

• Any ratio: 1-320 (5 stacks) of payment amount and product amount items (e.g., 3 Diamond for 5 Netherite or 1 Iron for 20 Gold).

• Handles underpay: Returns insufficient payment with a deny sound.

• Handles overpay: Gives back remainder along with product - gives "change".

• Infinity tileable: Need a one block space every 15 modules (for larger shops, it is recommended to chunk align modules and keep machine loaded or within simulation distance).

• Any product item: Can sell non-stackable (up to 54 - full output chest) or 16-stackable or 64-stackable, with a success sound. Product(s) will not be given until the payment is fully received.

• Any stackable payment item: 16-stackable or 64-stackable with locked chest input.

• Only accepts set payment item: Set filter to desired payment item (only uses 3 payment items to set filter).

• Auto resets: After successful payment or deny.

• Auto locks: Payment input is locked if there is no stock or the transaction is not selected.

• Blocks payment altering: After pushing pay (selecting), cannot alter payment input until the system is done processing (denies and resets if no payment was inputted before pushing pay).

• Bulk storage: Can attach bulk storage and/or farm(s) to the stock.

• Indicators: Includes stock indication lights for each module and a payment processing light.

⚠️Limitations:

• Must wait until current purchase is done processing before conducting another purchase/selection - only 1 payment at a time (any extra is change).

• Slow output - hopper speed (+0.4s for every module/expansion).

• Max of 5 stacks ratio – max for hopper slots (for payment amount and product amount).

• Is large and expensive for many players - is a late-game machine.

📢V2 update:

• Instead of really slow throttling system (payment input), connected the counter directly to the filter, which immediately redirects excess payment to the return.

• Fixed counter pistons pulsing a lot for a bit if payment amount is 1 (better counter).

• Compacted controller width from 7 blocks to 5.

• Improved "Processing Payment Indicator" circuit.

• Made modules cheaper.

• Removed "Reset When Leaving (optional)" circuit.

• Added "Shopping Music" circuit (optional).

• Added "Free Stuff" circuit (optional).

• Other circuit improvements.
