- You can precisely tweak every shade/tint so you can incorporate your own brand colors. No AI or auto generation!
- It helps you build palettes that have simple to follow color contrast guarantees by design e.g. all grade 600 colors have 4.5:1 WCAG contrast (for body text) against all grade 50 colors, such as red-600 vs gray-50, or green-600 vs gray-50.
- There's export options for plain CSS, Tailwind, Figma, and Adobe.
- It uses HSLuv for the color picker, which makes it easier to explore accessible color combinations because only the lightness slider impacts the WCAG contrast. A lot of design tools still use HSL, where the WCAG contrast goes everywhere when you change any slider which makes finding contrasting colors much harder.
- Check out the included example open source palettes and what their hue, saturation and lightness curves look like to get some hints on designing your own palettes.
It's probably more for advanced users right now but I'm hoping to simplify it and add more handholding later.
Really open to any feedback, feature requests, and discussing challenges people have with creating accessible designs. :)
There's so much more to do with tools like this, and I'm really glad to see it.
My partner shares our journey on X (@hustle_fred), while I’ve been focused on building the product (yep, the techie here :). We’re excited to have onboarded 43 users in our first month, and we're looking forward to getting feedback from the HN community!
There are some Amish people who rebuild Dewalt, Milwaukee etc battery packs. I'd like a repairable/sustainable platform where I can actually check the health of the battery packs and replace worn out cells as needed.
To give you an idea of the market, original batteries are about $149, and their knockoffs are around $100.
I've been wondering for a while if the display on ebikes could also be a more open and durable part of it.
Building a new layer of hyper-personalization over the web. Instead of generating more content, it helps you reformat and interact with what already exists, turning any page, paper, or YouTube video into a summary, mind-map, podcast, infographic or chat.
The broader idea is to make the web adaptive to how each person thinks and learns.

I'm putting a bunch of security tools / data feeds together as a service. The goal is to help teams and individuals run scans/analysis/security project management for "freemium" (certain number of scans/projects for free each month, haven't locked in on how it'll pan out fully $$ wise).
I want to help lower the technical hurdles to running and maintaining security tools for teams and individuals. There are a ton of great open source tools out there, most people either don't know or don't have the time to do a technical deep dive into each. So I'm adding utilities and tools by the day to the platform.
Likewise, there's a built in expert platform for you to get help on your security problems built into the system. (Currently an expert team consisting of [me]). Longer term, I'm working on some AI plugins to help alert on CVEs custom to you, generate automated scans, and some other fun stuff.

AI sprite animator for 2D video games.
It is a tool that lets you create whiteboard explainers.
You can prompt it with an idea or upload a document and it will create a video with illustrations and voiceover. All the design and animations are done by using AI apis, you dont need any design skills.
Here is a video explainer of the popular "Attention is all you need" paper.
https://www.youtube.com/watch?v=7x_jIK3kqfA
Would love to hear some feedback
The animations / drawings themselves are solid too. I think there's more to play with wrt the dimensions and space of the background. It would be nice to see it zoom in and out for example.
how does it work with long papers? will it ever work with small books?
will try it out tomorrow again
yes it should work.
> i can’t upload the document
Could you please drop an email to rahul at magnetron dot ai with the document. I will set things up for you
My first career was in sales. And most of the time these interactions began with grabbing a sheet of paper and writing to one another. I think small LLMs can help here.
Currently making use of api’s but I think small models on phones will be good enough soon. Just completed my MVP.
last month’s “what are you working on” thread impulsed me to upload this game to itch and 1 month later, i’ve got a small community, lots of feedback and iterations. It brought a whole new life to a project that was on the verge of abandoning.
So, I’m really grateful for this thread. https://explodi.itch.io/microlandia
Write a dev blog in Word format using Tritium, jot down bugs or needs, post blog, improve and repeat.
Next in the plans is adding more models and compare which one gives better results.
Drones are real bastards - there's a lot of startups working on anti drone systems and interceptors, but most of them are using synthetic data. The data I'm collecting is designed to augment the synthetic data, so anti drone systems are closer to field testing
Some are small tech jokes, while others were born from curiosity to see how LLMs would behave in specific scenarios and interactions.
I also tried to use this collection of experiments as a way to land a new job, but I'm starting to realize it might not be serious enough :)
Happy to hear what you think!
https://github.com/skanga/Conductor
Conductor is a LLM agnostic framework for building sophisticated AI applications using a subagent architecture. It provides a robust platform for orchestrating multiple specialized AI agents to accomplish complex tasks, with features like LLM-based planning, memory persistence, and dynamic tool use.
It provides a robust and flexible platform for orchestrating multiple specialized AI agents to accomplish complex tasks. This project is inspired by the concepts outlined in "The Rise of Subagents" by Phil Schmid at https://www.philschmid.de/the-rise-of-subagents and it aims to provide a practical implementation of this powerful architectural pattern.
Working on faceted search for logs and CLI client now and trying to share my progress on X.
Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard.
That seemed solvable.
Laboratory.love lets you crowdfund independent lab testing of the specific products you actually buy. Think Consumer Reports × Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid’s snacks, or whatever you’re curious about.
Find a product (or suggest one), contribute to its testing fund, and get full lab results when testing completes. If a product doesn’t reach its goal within 365 days, you’re automatically refunded. All results are published publicly.
We use the same ISO 17025-accredited methodology as PlasticList.org, testing three separate production lots per product and detecting down to parts-per-billion. The entire protocol is open.
Since last month’s “What are you working on?” post:
- 4 more products have been fully funded (now 10 total!)
- That’s 30 individual samples (we do triplicate testing on different batches) and 60 total chemical panels (two separate tests for each sample, BPA/BPS/BPF and phthalates)
- 6 results published, 4 in progress
The goal is simple: make supply chains transparent enough that cleaner ones win. When consumers have real data, markets shift.
Browse funded tests, propose your own, or just follow along: https://laboratory.love
It's interesting that a bunch of the funded products have been funded by a single person.
Do you know if it's the producers themselves? Worried rich people?

Then it’s on to the next project.
To provide trading insights for users.
I started this out of frustration that there is no good tool I could use to share photos from my travel and of my kids with friends and family. I wanted to have a beautiful web gallery that works on all devices, where I can add rich descriptions and that I could share with a simple link.
Turned out more people wanted this (got 200+ GitHub stars for the V1) so I recently released the V2 and I'm working on it with another dev. Down the road we plan a SaaS offer for people that don't want to fiddle with the CLI and self-host the gallery.
The insight: your architecture diagram shouldn't be a stale PNG in Confluence. It should be your war room during incidents.
Available as both web app and native desktop.
https://youtu.be/ZXXJrwNGh8A?t=36 shows wavelengths from around 200nm to 1000nm, but I've been using UV+IR+White LED lights currently and need to try a single broadband light source.
As well as playing with a very simple 3D printed canon ef mounted night vision tube - https://www.anfractuosity.com/projects/night-vision-tube-mou...
For example, 1 PCR reaction (a common reaction used to amplify DNA) costs about $1 each, and we're doing tons every day. Since it is $1, nobody really tries to do anything about it - even if you do 20 PCRs in one day, eh it's not that expensive vs everything else you're doing in lab. But that calculus changes once you start scaling up with robots, and that's where I want to be.
Approximately $30 of culture media can produce >10,000,000 reactions worth of PCR enzyme, but you need the right strain and the right equipment. So, I'm producing the strain and I have the equipment! I'm working on automating the QC (usually very expensive if done by hand) and lyophilizing for super simple logistics.
My idea is that every day you can just put a tube on your robot and it can do however many PCR reactions you need that day, and when the next day, you just throw it out! Bring the price from $1 each to $0.01 + greatly simplify logistics!
Of course, you can't really make that much money off of this... but will still be fun and impactful :)
Haunted house trope, but it's a chatbot. Not done yet, but it's going well. The only real blocker is that I ran into the parental controls on the commercial models right away when trying to make gory images, so I had to spin up my own generators. (Compositing by hand definitely taking forever).
- 30k requests/month for free
- simple, stable, and fast API
- MCP Server for AI-related workloads
It’s an iOS app to help tracking events and stats about my day as simple dots. How many cups of coffee? Did I take my supplements? How did I sleep? Did I have a migraine? Think of it like a digital bullet journal.
Then visualizing all those dots together helps me see patterns and correlations. It’s helped me cut down my occurrence of migraines significantly. I’m still just in the public beta phase but looking forward to a full release fairly soon.
Would love to hear more feedback on how to improve the app!
It's already working, and slightly faster than the CPU version, but that's far from an acceptable result. The occupancy (which is a term I first learned this week) is currently at a disappointing 50%, so there's a clear target for optimisation.
Once I'm satisfied with how the code runs on my modest GPU at home, the plan is to use some online GPU renting service to make it go brrrrrrrrrr and see how many new elements I can find in the series.
One of the best I’ve seen in this thread!
Good luck with your mission!
man, myself needs work
https://github.com/jakeroggenbuck/kronicler
This is why I wrote kronicler to record performance metrics while being fast and simple to implement. I built my own columnar database in Rust to capture and analyze these logs.
To capture logs, `import kronicler` and add `@kronicler.capture` as a decorator to functions in Python. It will then start saving performance metrics to the custom database on disk.
You can then view these performance metrics by adding a route to your server called `/logs` where you return `DB.logs()`. You can paste your hosted URL into the settings of usekronicler.com (the online dashboard) and view your data with a couple charts. View the readme or the website for more details for how to do this.
I'm still working on features like concurrency and other overall improvements. I would love some feedback to help shape this product into something useful for you all.
Thanks! - Jake
Still working on growing the audience.
Last month was better and this month, well, I can't concentrate for long and I distract very easily, but I seem to be able to do more with what I have, and a small sense of ambition that I might be able to do bigger things, might not need to drop out of tech and get a simple job, etc., is returning.
I am trying to use this inhibited, fractured state to clarify thoughts about useless technology and distractions, and about what really matters, because (without wishing to sound haughty) I used to be unusually good at a lot of tech stuff, and now I am not. It is sobering but it is also an insight into what it might be like to be on the outside of technology bullshit, looking in.
I'm calling it a "Micro Functions as a Service" platform.
What it really is, is hosted Lua scripts that run in response to incoming HTTP requests to static URLs.
It's basically my version of the old https://webscript.io/ (that site is mostly the same as it was as long as you ignore the added SEO spam on the homepage). I used to subscribe to webscript and I'd been constantly missing it since it went away years ago, so I made my own.
I mostly just made this for myself, but since I'd put so much effort into it, I figure I'm going to try to put it out there and see if anyone wants to pay me to use it. Turns out there's a _lot_ of work that goes into abuse prevention when you're code from literally anyone on the internet, so it's not ready to actually take signups yet. But, there is a demo on the homepage.
- A front-end library that generates 10kb single-html-file artifacts using a Reagent-like API and a ClojureScript-like language. https://github.com/chr15m/eucalypt
- Beat Maker, an online drum machine. I'm adding sample uploads now with a content accessible storage API on the server. https://dopeloop.ai/beat-maker
- Tinkering with Nostr as a decentralized backend for simple web apps.
This month doubling down on a small house cleaning business that I acquired https://shinygoclean.com
Instead of code, seems like SOPs have become new love language!
Code obeys logic. People obey trust. That’s the real debugging. Still learning!
https://github.com/scallyw4g/bonsai
I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.
It has some rough edges, but I use it a ton and get a lot of value out of it.
I just took Qwen-Image and Google’s image AIs for a spin and I keep a side by side comparison of many of them.

AppGoblin is a free place to do app research for understanding which apps use which companies to monetize, track where data is sent and what kinds of ads are shown.
I want to write voip plugins using a modern tool chain and benefit from the wider crate eco system
It’s got the base instruction set implemented and working. A CRT shader, resizable display, and swappable color palettes.
I’m working on sound and a visual debugger for it.
I have some work to do on the Haskell TigerBeetle client and the Haskell postgresql logical replication client library I wrote too.
(But also just launched https://ChessHoldEm.net this weekend)
right now, it’s a better way to showcase your really specific industry skills and portfolio of 3D assets (i.e., “LinkedIn for VR/XR) with hiring layered on
starting to add onto the current perf analysis tools and think more about how to get to a “lovable for VR/XR”
And an agentic news digest service which scrapes a few sources (like HackerNews) for technical news and create a daily digest, which you can instruct and skew with words.
I am building a tool that gives automated qualitative feedback on websites. This is the early and embarrassing MVP: https://vibetest-seven.vercel.app/product
You provide your URL and an LLM browses your site and writes up feedback. Currently working on increasing the quality of the feedback. Trying to start with a narrower set of tests that give what I think is good feedback, then increase from there.
If a tool like this analyzed your website, what would you actually want it to tell you? What feedback would be most useful?
Nice to call it feature complete and move on!
