> AI-powered sustainability assistantDemo: greensteps.devlix.org
Built this during a hackathon. The goal was simple: make sustainability less preachy and more usable in real life.
What it does
• Step-by-step, personalized guidance
• Interactive AI flows instead of info dumps
• Focus on practical actions, not “save the planet” lectures
Timeframe
• ~2 days, end to end
My part
• Backend + AI
• Most of the frontend
Tech
• FastAPI backend on EC2
• Gemini Live API (audio)
• PostgreSQL (RDS)
• React frontend on S3 + CloudFront
• CloudWatch for logs
What I learned
• Time limits force better product decisions
• Real-time AI + WebSockets get messy fast
• People engage more when tools guide, not judge
Not perfect, but it works and we shipped. Iterating next.
@PianoMan00Day 2/365!
• Flavortown ship certs
• Flavortown support team
• Gardener stuff
• Worked on improving loading speeds for Visionary and I made it possible to access your profile from the ideas page
• Huddle in #C09SXNX0GNP|!
@mathias0:50days: Day 50/50 (10/10)

- Bulb api (bubulb), onedrive-proxy and archiving tool (goarchiver) got shipped to Midnight
- Archive stuff: archived thevalleyofcode and my website
- Add a dropbox to the 1drv proxy
- Somehow make a workflow public so user can choose what version to build Shipped to Midnight too
- ~Make a real website for mathiasd.fr Way better now (I'm going to write a post about 50days on it soon)
- Make something in C(++): forgot so many times :(
- Publish dotfiles~: MathiasDPX/dotenv
- Setup Coolify on my server: I installed it but it took too much resources so I moved to docker composes and glance to monitor
Extras:
- Started to make an Immich like website cuz like Coolify it took too much resources
- Got a new server so I've installed it
- Bought a Midnight ticket
- Finished AoC 2025 and optimized it

@hex40:50days: day 50
I am writing this at 12:21 AM, January 1st, 2026, which technically means that I missed my update for today, but who cares?
Today, after not getting a lot of sleep, I mostly prepared all of my goodbyes and tried to tie up loose ends. Spent much too long drafting my holy yapparonie for #C0818RRJGDA|, dropped a fragment for an ARG (:eyes_shaking:), and dmed a few people that I still have stuff to finish up with.
you know, this is my own challenge and i've only achieved 2/8 of my goals. I didn't ship Fireside, learn Rust, or finish #C09MJJV82QY|. I missed 3 days. many of my updates were nothing burgers. but maybe that's not what really mattered. maybe what did matter was coming back (mostly) every single day, trying my absolute hardest to make these 50 days count. and I think I succeeded. I made two projects that made people smile, I solved a bunch of AoC puzzles, I learned about code organization in Godot, and I kinda understand Rust now?
I don't know what's going to happen tomorrow. Maybe this under-13 fiasco is just an elaborate prank. Maybe they're going to give me a few extra days here. As I write this, I'm still living in the world where my Slack account is active. I have no clue what's going to happen next - tomorrow, over these 3 months, over the next 3 years. But I'm grateful I got to hack and build during these 50 days alongside all of you.
catch you on the flip side <3
(also, yes, hand reveal :shocked:)
@qwwertyz0day 49
• how many days have I forgotten about updating this??:sweatdrop:
• succesfully finished my 50 day art challenge!! I'm very proud of myself!
• I finished all my physical to-do goals, shipped my game(stellar ship!), finished the website, also drew everyday
• my sleep and excercise is still messed up though
• what do I do after this? What's my new year resolution? i've been doing college apps for the entirety of christmas break and I'm losing my mind. I just need one school to accept me and end this nightmare:cryign:
@Akaalroop0I made a bot which gives you minecraft recipes!
It was a pain generating all the 519 images of crafting recipes, but yeah I did it! :yay:
I made it in Kotlin so it will eat all the RAM on my RPI Zero 2W on which it is hosted :thumbup-nobg:
Hopefully you like it!
It’s @MCRecipes !
Just ask for any recipe like: @MCRecipes oak boat

@deanayoung30Guys, I made a site where you can pay for 3d printing, I know that other people have similar things but I thought why not create another one :ultrafastparrot:. I also created an in web slicer which you can drag and look at the file you uploaded. I think its pretty cool! Give it a try! I would love to get some feedback for improvement! You can try it here: printstack.org
@logabe0Day 46 (feeling the pressure 😓):
• Spent most of the day w/ extended fam which was fun
• Finished my PCB on a lock-in call in #C09M3V4E7MM|
• Might practice clarinet now? I'm attempting to learn Moonlight Sonata
Tomorrow:
• Submit my PCB to #C083S537USC|
• Work towards polishing either Burning Rain or Milkyway Pets so I can get that stellar ship
• Practice Clarinet
below is my incredibly messy wiring
@logabe0Day 43 (1 week left!!!):
• Submitted Sands of Time for #C0A2YUQ33RP| and played everyone elses games. I'm now 12 hours closer to Overglade :cat-cool:
• Nearly finished with my #C09RKNVS5SB|. I really didn't want to be working on it during Christmas, but I just need to write docs and ship it.
• Sorted out christmas gifts for the fam
@revi0programming languages compile down to bytecode, then machine code. its all machine code at the roots, machine code all around
you could say machine code is the final layer, the most basic, the most fundamental thing the computer parses
but what if you took a different approach?
PARAMATH!! the language that compiles NOT TO MACHINE CODE, but to MATH!! it uses math to approximate binary logic, which means now (at least in theory) you can run code on a scientific calculator!!
like everything i make, its a proof of concept, and this is my most recent and most proudest brainchild of all!
the github repo is github.com/kaemori/paramath, dont look too close :3c@ajhalili20060Not technically a ship (YET), but if you do run a community service/app for the Hack Club community (note: not YSWS/event specific) and needs uptime monitoring powered by GitHub Actions + Issues + Pages? I already set up Upptime so you don't have to mingle with secrets and stuff. Just edit the .upptimerc.yml to add yours, send it as a pull request, and it's ready to go once merged.
You can see the latest status and more at status.hackclub.community and the backing repo at github.com/hackclub-community/community-services-status. Or, you can hop at #C0A4DLGF8TD| to get notified when a new incident or scheduled maintenance pops up on the radar, alongside any updates.
Read on github.com/hackclub-community/community-services-status/blob/master/CONTRIBUTING.md on how to setup uptime monitoring for your community service.
@areallyawesomeusername0shipping symphony! It's like chatgpt but on a slack workspace! It's agentic too!

@logabe0Day 38/50:
• Started designing my first-ever PCB ‼️ It was a lot easier than I though :D I'm gonna (hopefully) finish it tomorrow.
• Sorted some bugs in the Milkyway website.
• Practiced clarinet for the first time in like a week - started playing a new song.
• Spent 2 hours working on my #C09EZSEMB16| projects. On track to ship Burning Rain by the end of the week!
Goals for tomorrow:

@Karo0I just shipped an update to libreassistant.vercel.app!!
Libre Assistant is an open-source AI chat interface that uses ai.hackclub.com to provide free, unlimited access to over a dozen models from 6 AI labs, including but not limited to Gemini 3.0 Pro, Gemini 3.0 Flash, and GPT-5.1 Thinking!
The update I just shipped added three things:
1. Gemini 3.0 Flash, Qwen3-Next, and Qwen3 VL 235b
2. A new free search tool that uses search.hackclub.com to provide accurate and fast agentic search
3. Keybinds for both MacOS & other systems
@tacy0day 36 of 50 days to 2026!
Today I ended up doing a ton of work on my auth project. I have it almost ready to ship but I need to finish up the last few features and deploy it first. 🤞I can ship it tomorrow.
I made a little snowflake website for #C0A277A4FP0| with flask which was a fun distraction. Super simple but it was fun to build and I tried deploying to railway for the first time! That deploy experience is sliiiiiiick. They have made it so easy to get your first project deployed and with a url its incredible. I'm so very tempted to make an OSS railway as my next project. We shall see.
@logabe0Day 36:
• Started making my gift for #C09RKNVS5SB| and had a blast
• 1½ hours of work on Burning Rain. Aiming to ship it by sunday!
• Played piano and helped move a fridge
• Friend group drama is crazy
@tacy0day 34 of 50 days to 2026!
I had so much happening today. I ended up having meetings from 4 till 10 which was fun. I attended an AMA with Quinn Slack which was insanely cool and I also did quite a few OYAC meetings and got to meet the other leaders from across the country and hear about some of the frontline advocacy work which was amazing and really encouraging.
Independently I also worked on an interesting little project showcased below which I will be sharing more about soon as well as some more mc hacking with one of my friends. Oh and I also made a keychain in onshape for haxmas. Hopefully I can ship my semi secret project tomorrow and make a nice showcase video :)
@ionixv0hai chat today im shipping hack club radio, an internet radio channel that you can add your favorite songs to!
ionixv.hackclub.app/radio.html
it runs a simple azuracast instance where i put your requests into a looping, shuffling playlist!
@ionixv0i'm shipping a simple, no bs TUI client for the #C099S1LLFFU| API.
it is public domain software. anyone may copy, modify, publish, use, compile, sell, or distribute it.
github.com/IonixV/hackaiTUI
@logabe0Day 30:
• Worked on Burning Rain in a huddle! I think I'm gonna ship it soon :D
• Did a bit of work on my website
• friend stuff 😐
Got a job tomorrow which is nice, but it's be all day so I'm gonna be exhausted afterwards :(
@areallyawesomeusername0oh my god im so tired but look, i made my first slack bot! the name is KittenBot! it can show you cat facts, gifs, pictures and you can chat with an AI which has a cat personality! this slack bot is for Meow YSWS so that's why I made it cat themed!
repo: github.com/Snowflake6413/kittenbot
image below shows an example of the AI in action! :aga:
@aviad0Hiiiiiiiii
I wanted to share a small (but fun!) project I built recently — a function-grapher written in C.
it uses ASCII characters because I have zero shame and basically no UI experience, kind of chaotic, but realy fun to mess with.
If you want to check it out, break it, improve it, or just laugh at the code structure — here it is:
github.com/Aviadalm/C_Graph_Engine
Would love any feedback, ideas, or cursed suggestions 💖
@hex40:50days: day 22!
finally packed up the #C09676ZTG8P| stickers! hopefully I can ship them out by friday :D it'll be good to finally get this off my shoulders :hs: spent the rest of the day on AoC - part 1 was easy enough but I couldn't for the life of me get part 2 to work :( maybe if I have free time tomorrow I can try again.
@ajhalili20060Not technically a ship, but you need a knotserver for your git repos on Tangled but can't find knot1.tangled.sh? No worries, I got you! I successfully have one running at knot.hackclub.community with SSH port 33939 on #C056WDR3MQR|. Just ping me for your AT Proto DID/handle at #C07H1R2PW9W| (or via DMs if you will) for access. (don't forget to get your SSH pubkeys added on Tangled to push commits)

@ingobeans0i made a game to help lighten spirits in these dark winter times, called winternight! its really cute and wholesome (and short). made in rust for siege :siege:
hope you like it :>
github: here
@Smeagle0Sticky notes you can pin to any window (i am finally going to ship something!)
@matmanna0made this library a little while ago but never officially "shipped" it here
do you play the electric guitar or bass? are you a fan of reverse engineering and/or (music) hardware hacking? if so, my new venture, Bender, might be interesting to you:
Aiming to liberate proprietary music hardware through protocol reverse engineering, my first project in this space, LtAmp.py, serves to enable interfacing with the LT-series amps produced by a certain giutar manufacturer that rhymes with Bender and names their products after horses. As of now, the library:
• is fully MIT-licensed, source-available, and star-able on GitHub
• is installable through pip and listed on PyPI (the python package index)
• supports almost all basic functions including preset management, footswitch slot configuration, and metadata
• enables the creation of other apps and tools such as CLIs, alternative GUIs, and augmentation platforms
• is fully tested with the LT25 model (but should work with others such as 40-100 and Rumble)
• is the first non-.NET solution for connecting to this series of amps (that I know of)
If you're at all interested in this project or anything else I'm planning at Bender, please leave a star (⭐), follow the GitHub org, or reply/DM/issue with suggestions, questions, ideas (I'd be thrilled to chat about anything but music tech excites me a lot!)
@ingobeans0hello!! last week I made a super mario maker inspired game for siege, called Goblin Maker! you can build and share levels, and browse levels made by other people!
Github: github.com/ingobeans/goblin-maker
Itch: gnarmi.itch.io/goblin-maker
the game was written in rust, but the server is a flask app hosted on Nest. entire project took about 35 hours :>
i'd love it if you checked it out (you can play in your browser)! make some levels! thanks <3
@logabe0Day 12 of :50days::
• Posted the Windows and Linux builds for Milkyway Pets in #C09EZSEMB16| in order to get some feedback before I ship it. I got a lot of feedback and have learnt a lot from getting it into the hands of other people for the first time. Some of the issues I've noticed:
a. Use a makefile to automate the build process. Automated testing is hard to make work in this context, but it would also be useful.
b. Improve the config experience: Already partially there! The program now looks for a config file in the same directory as the program, and the program come with a template for the config file. I'm considering moving away from TOML to something simpler and more forgiving with user errors.
c. Get rid of the Space-to-toggle-window-decorations thing. It's confusing, and being able to drag the window should be the default on most platforms. It's still needed on Wayland, since they can't set their own position.
d. Better error handling: Currently errors either get ignored or are printed to the console. The windows users found this a bit confusing since they aren't running it from the terminal, so a graphical error window would be useful.
e. Better installation guide: When I finally ship this project, it needs to have a good guide to installation and usage, since running the program requires you to find both your Hackatime API key and a :milkyway: Session ID. Somebody had an issue with getting their sessionid cookie, but I couldn't replicate it. A backup method would be useful just in case.
• Studied for my Japanese exam tomorrow. I focused on listening, which I've been neglecting up until now. I'm not feeling the greatest about tomorrow, but I'll give it my best shot :salute:
• Did a practice exam for my licence test tomorrow and got a cool clean calm and collected 100% LETS GOOOO!! 💥 💥 ‼️ I'm either gonna sit the exam tomorrow or the day after, depending on how I'm feeling.

@freddie0Ducky Diagnostics is a project designed for the PicoDucky (but just python for now)!
It runs a series of commands and saves output to debug.txt with some formatting and voilà, a detailed list of spec's and more information about your device. You can download it from this GitHub link. (this was made for YSWS #C08QZ0P7QP6|)
@Lapis0I got tired of there being no proper Discord RPC tools for Audacious (my main local music player app) so I made one myself!
If you for some reason also use Audacious too here you go!

@lily0Just finished building Totally normal notes.
Try it. You won't regret it.

@Angad0I recently started using Amp when working on some HQ stuff, but then realized that I wouldn't be able to easily switch to my personal account so I could use Amp's free plan on personal projects. I decided to make amped, a tool that switches out Amp's secrets.json file to have a token for the chosen account.
Since I haven't used Go in a while, I chose to use this project as a refresher. It's also the first I've ever made a program that interacts with the system keychain to handle secrets, and I'm pretty happy with how it turned out.
If you have Go, you can install it via go install github.com/slashtechno/amped@latest
Otherwise, there are releases with dynamic release notes!
@lily0just finished getting a production instance of my webapp called Linus Drop Tips.
it is a crowdsourced site of everything Linus from LTT has dropped :3

@ShyMike0Ever wanted to use multiple :wakatime-dark: WakaTime instances (eg. using both Hackatime and WakaTime at the same time) but waka-relay was just too hard to use?
Worry no more! I just finished working on my new project, timesplit that aims to make that much easier! :3
:github: Repo: github.com/ImShyMike/timesplit
(and if you do decide to use it, you should add rustytime to the list of server urls ;) - more info about it can be found on it's ship post)
@freddie0Just shipped linked my github pages site to my new domain. It looks rubbish on mobile and has no info yet but all will come soon. freddieyershon.co.uk
@louisa0project 1 (oct 5 to oct 18) - my personal website getting a much needed revamp
day 6 - was supposed to post yesterday but got caught up in fd work 😭 all i did was add the embed as seen in v1peridae.me:heavysob: i've been working on waht im gonna teach meghana today! i think im ready to ship the site then finish up working on CursedOS (rust os) !
@ShyMike0haven't posted here in a while but i just finished (the mvp) for my project rustytime :D (currently at ~75h)
• what is it? It's like :wakatime: WakaTime but FOSS and made with a :rust: Rust backend, :svelte: Sveltekit frontend and :postgres: TimescaleDB (Postgres extension)
• why? I though it would be a cool project :colon3:
• is it good? Idk :shrug_y2: but you can judge it for yourself here :P
• is it fast? It's pretty speedy! Over 1500 heartbeats/second on my machine!
repo: github.com/ImShyMike/rustytime (you should give it a star :thumbup:)
please send stuff you think i should add in the thread :)
edit: also check out timesplit if you want to use this + hackatime at the same time! (ship post here)@louisa0starting a new challenge for myself to ship a new technical project every 2-3 weeks. hoping to be able to stick to this and by the time i graduate i should have 12 new projects at the minimum :)
project 1 (oct 5 to oct 18) - my personal website getting a much needed revamp
i've had the same website for almost a year and a couple of month now and it's in html/css which about a year and a half ago was the only web-dev stuff i was proficient in :heavysob: i'm now good with astro :P so i'm gonna be revamping my site in astro and today i started working on the design for it! spent like 5 hours in a huddle with some friend in my channel locking in :)
next steps - start working on the code + figure out the rest of the pages
