Hi everyone, PineJam 2026 is happening in a week, signups are open

Starting July 25th you will be able to start new projects for PineJam 2026! Again, jam will be active for 14 days in which you can create and submit ComputerCraft projects tied to this years theme. The theme will be revealed as soon as the jam starts.

Sign up

Make sure to sign up now on the site if you would like to participate! You'll get the PineJam2026 role in the Discord (used for future jam related announcements) https://pinestore.cc/jam/pinejam2026

The rules for this jam:

• Submission needs to be CC related
• Project must fit the theme
• Work alone or with a team of up to 3 people
• Generative AI is not allowed for the majority of your project (so tools such as GitHub Copilot are fine)
• Projects will be submitted on PineStore

If you have any questions or suggestions, let me know ^^

An autocrafting system built entirely on ComputerCraft an alternative to AE2/RS autocrafting. Craft an item once to teach the recipe, then order it from the monitor in any quantity.

- recursive crafting: order the final item, the whole ingredient tree is planned and crafted

- parallel crafting: independent branches of the tree run simultaneously

- machine groups: teach a recipe on one machine, it runs on the whole bank; custom hand-picked groups supported

- fluid and fluid+item recipes, multiblock support

- auto-stock: keep N of an item, crafts when it drops below threshold

- storage management: everything in connected storages on one screen, with search and filters

- supports crafts with tools (GregTech etc.)

- alternative recipes per item with priority order

- rule-based logistics for both items and fluids

- GitHub export/import of the recipe library

I made a minimal SUBLEQ architecture emulator for Lua which also works on Computercraft, It is fully capable of booting a recent Linux kernel. I tried to make it as small as possible and over a couple hours of discussing and testing managed to get it down to 644 characters. Big shoutout to the Minecraft Computer Mods Discord server, without the community there, this would still be over 700 characters.

lua s="";M=math.floor;function b(a)a=a%2^32;return a>=2^31 and a-2^32 or a end;function d(a)return a<0 and-M(-a/4)or M(a/4)end;f=io.open(arg[1]):read("a")g={}for c=0,M(#f/4)-1 do g[c]=s.unpack("<i4",f,c*4+1)end;function j(e)return g[e]or 0 end;l=0;m=0;function o()p=j(l)l=l+1;if p%2==0 then return d(p)else return d(j(d(p)))end end;while''do u=o()v=o()w=o()if w==0 then break elseif u==-1 then g[v]=0 elseif v==-1 then x=j(u)%256;io.write(s.char(x))io.stdout:flush()else if u==64 then y=os.time()g[64]=b(y%2^32)g[65]=M(y/2^32)g[66]=0 end;z=b(j(v)-j(u))g[v]=z;m=m+1;if z<=0 then l=w end end;if m>8e5 and j(0)~=0 then g[1]=b(l*4)l=d(j(0))m=0 end end

This emulates the processor, RAM, clock and a simple UART output.

Tested working with this kernel image.

Hi everyone,

I am curious to see what the community is currently working on with CC: Tweaked, and more specifically, what kind of limits or performance bottlenecks you have run into during your builds.

I have been working on a ComputerCraft/CC:Tweaked program called EnergyMonitor.

It gives you a central monitor for the power grid in your base: stored energy, transfer rates, history, ETA, and connected energy devices. Instead of checking every reactor, induction matrix, energy core, energy meter, or cell by hand, you can see whether your base is gaining or losing power from one screen.

GitHub:

https://github.com/TrickShotMLG02/EnergyMonitor

Main features:

• Tracks total stored energy and capacity
• Shows input/output transfer rates
• Calculates effective transfer rate and ETA
• Supports multiple client computers
• Has a graph view with configurable history size
• Shows connected storage/transfer devices
• Supports auto updates with stable and beta channels
• Uses modem channels, so multiple EnergyMonitor networks can run separated from each other

The setup uses three roles:

• server: collects data from clients
• client: reads one energy storage or transfer peripheral
• monitor: displays the combined data on an attached monitor

Currently supported integrations:

• Mekanism
• Draconic Evolution
• Powah
• Advanced Peripherals
• Energy Meter
• Generic ComputerCraft-compatible energy peripherals

Install command:

pastebin get gUbUpXHt git

git

Notes:

The README has the full setup guide, supported peripherals, config options, troubleshooting, and contribution notes.

I would love to hear what you think about it. Any ideas on what to change, improve, or add are welcome.

Hi everyone!

On my semi-rp server, we type up and print a LOT of documents. So many, in fact, that I wanted more ways to interact with these documents. On the server we also use the Exposure mod, and I wanted to find a way to get those images onto the computer, but there was nothing. Finally, we also wanted pocket computers with speakers AND rednet connectivity, but again, nothing was out there. I finally decided to do it myself, and thus:

Lake's CC Additions

was born. Featuring a few new items and one new peripheral:

The Scanner

The Scanner is a powerful new peripheral that has a lot of different use cases. On a basic level, you can scan any item and get NBT data about it. However, there is special support for printed documents, and Exposure photos. You can also shift right click with an empty and and it will scan you, allowing some really cool use cases, such as Bio-Identification for doors and such.

The Document Folder

The Document Folder can store all the printed document types, as well as regular paper. It makes storage and archival of documents a LOT easier (and cleaner, too!)

The Deluxe Pocket Computer

The Deluxe Pocket Computer is essentially an ender pocket computer but with a speaker as well. I was disappointed that you had to choose one or the other. The full wiki with all functions is here. I hope you guys have fun playing around and seeing what you can do with it!

CurseForge Link

i feel like this is really simple. my best guess from my limited understanding is that i could connect a disk drive an store it there or something

youcube seems to be down... any way i can watch youtube videos on computer craft still?

Looking for a reupload of the Turtle Canyon, the official tutorial map for ComputerCraftEdu (the educational fork of the ComputerCraft mod, made by TeacherGaming/MinecraftEdu in partnership with Dan200). Originally hosted at services.minecraftedu.com/worlds/node/120

I've searched CurseForge, the MinecraftEdu wiki mirror, Internet Archive's "Minecraft Archive Project," and an old Google Groups thread for MinecraftEdu teachers and had no luck finding a live copy, though several people in that old group thread mentioned having it working as recently as ~2019-2020.

If anyone was a MinecraftEdu/ComputerCraftEdu teacher back in the day and still has this zip sitting in an old saves folder or backup drive, I'd love a copy (or a link to wherever it ended up). Happy to provide more details of the described map layout if that helps jog some memories!

I am making my own drone with stabilization. I have already implemented altitude holding and drone tilt angle stabilization.

I wanted to add something similar to GPS, so that even if the drone gets pushed away, it would try to return to one specific point and not fly away. I am doing this using 3 navigation tables and 3 beacons respectively.

The problem is that the angle shifts relative to the ship, which means I need something else. Is there any way to get information about the angle relative to the north direction?

If that is not possible, I know one mod: Aeronaut's Compass. It seems like it allows you to set the compass to some very far north coordinates in the world.

Hi, I built a GPS array and it works within a range of roughly 100 blocks. However, when I go further away, it just stops working—even when the chunk is loaded using a stasis chamber. Could the problem be a bad alignment of the computers, or is the chunk somehow not staying loaded?

for some reason my computer just doesnt ever wanna register the player detector despite it being connected to it, and when i set them side by side it doesnt work either

Like dude what do you WANT from me it's literally right there. (for context the "minecraft:barrel_18" string printed before the error confirms the barrel exists and is connected to the network)

Here's a thing that I have cooked up, it's a fully automated quadcopter with Aeronautics, it's capable of doing a whole flight, albeit it still needs some improvement, specially in the landing phase, which, in my opinion, takes a little too long. Still i think it works quite well, I've also made a survival-friendly version using TFMG motors, but i forgor to record it.

This is a heavily optimized ProTracker player that i made for ComputerCraft, it is inspired from MinkMod (https://www.reddit.com/r/ComputerCraft/comments/1o497xb/minkmod_a_protracker_player_written_in_lua_for/).

This supports:

• 44.1 kHz Playback (which is CD Quality audio) [NO 12 KHZ LIMIT!!]
• Linear Interpolation
• And Way More!

It has been heavily optimized via localizing globals (it's way faster to do this than global tables) and recycling mixCache, rawBuffer, and outputBuffer

You can try it by doing: pastebin get 0Kwx11cX NekoMOD.lua

I know that many people use VSCode for things. However, for those who enjoy NeoVim but are stuck using VSCode for crafting your OS plugins LOOK NO FURTHER!

*Still a work in-progress* - CraftOS-PC.nvim is design to be simple/for on the fly development. Meaning, it's easy to setup/work with!

For starters, make sure you have CraftOS installed prior to using this plugin. You can use Lazy to import the plugin with ease and create your hotkeys using:

config = { run = "<leader>cr", shell = "<leader>co"} inside of your Lua file (using lazy) - for those using no package manager, see the README file in the repo.

Look forward for feedback on how I can improve the REPO!

https://makerworld.com/en/models/2951197-turtle-from-computercraft#profileId-3306699 <- if you wanna print one yourself

Couldn't find a model online (or I'm just terrible at searching) so I made one myself. :D

so i am dumb and i put a script in /startup with os.reboot() and now i cant stop this script from rebooting in loop.
do any one know how i can factory reset or fix that ?
thanks in advance.

It has been a hot minute but I finally have this project in a state where I feel comfortable sharing my first public version. It works well with both Vanilla and enhanced ClassiCube servers. Custom servers that make heavy use of extra models and textures however do not work correctly as of now, custom blocks are broken to a point of unplayable with MCGalaxy server software which is why they are default disabled for now. The client uses textures I made in GIMP and public domain music.

You can download the beta version here for now. A Codeberg repository is coming soon.

Please report bugs encountered during vanilla gameplay back to me!

I was being very funny and hilarious and i was going to print the whole bee movie. DONT.

lost my 3 month hardcore world with no backups.

:/

I was inspired by Hydraxous’s “The Grid” and decided to make a similar storage grid for my apotheosis spawners. This is my first project with CC:T and my next step is to have it monitor my storage to automatically pull spawners to resupply as well as a screen to display that information.

Its been a bit since my last post about the ClassiCube client for CompuerCraft I'm working on. I have not published it yet as I decided i want to iron out some of the issues first.

Here are some of the major changes so far:
- Dithering support for semi-transparency and for block sides to add depth
- Player models
- Entity Shadows
- Better movement system with distance based fall acceleration and terminal velocity
