Show HN: A Digital Twin of my coffee roaster that runs in the browser
9 by jvkoch | 1 comments
I built this website to host a data-driven model of my coffee sample roaster. I realized after 20 or so batches on the machine that while the controls are intuitive (heat, fan, and drum speeds), the physics can be unintuitive. I wanted to use my historical roast data to create and tune a model that I could use to do roast planning, control, and to help me build my own intuition for roasting. This website lets you interact with my roaster in a virtual, risk-free setting! The models are custom Machine Learning modules that honor roaster physics and bean physics (this is not GPT/transformer-based). Buncha math. The models are trained on about a dozen real roasts. The default bean model is an Ethiopian Guji bean. My next steps are to add other roasters and the ability to practice control/reference tracking.

Show HN: GYST – Digital organizer that replicates the feeling of a physical desk
5 by ricroz | 0 comments
Hi HN! I’ve been working on a tool that merges file explorer, whiteboard, bookmarking, note-taking & simple graphic design into one lightweight interface. The idea is to make all these tools feel like one fluid space instead of 5 separate tools. The hope is to replicate the feeling of a physical desk : where order and freedom coexist. This 15-min video walks through the current alpha and the vision for the full product : https://youtu.be/AcWzuBBuiPM I’d love your feedback — especially around the concept and UX. The alpha is online if you want to try it: https://gyst.fr This is a solo project for now, inspired by the “second brain” / PKM movement and my own frustration with fragmented tools and outdated UX.

Show HN: I made an online Unicode Cuneiform digital clock
16 by OisinMoran | 6 comments
I got the idea to pay homage to the people who gave us base-60 time, and in the process discovered that Cuneiform is in Unicode.

Show HN: I built an AI agent that turns ROS 2's turtlesim into a digital artist
7 by ponta17 | 1 comments
I'm a grad student studying robotics, with a particular interest in the intersection of LLMs and mobile robots. Recently, I discovered how easily LangChain enables the creation of AI agents, and I wanted to explore how such agents could interact with simulated environments. So, I built TurtleSim Agent, an AI agent that turns the classic ROS 2 turtlesim turtle into a creative artist. With this agent, you can give plain English commands like “draw a triangle” or “make a red star,” and it will reason through the instructions and control the simulated turtle accordingly. I’ve included demo videos on GitHub. Behind the scenes, it uses an LLM to interpret the text, decide what actions are needed, and then call a set of modular tools (motion, pen control, math, etc.) to complete the task. If you're interested in LLM+robotics, ROS, or just want to see a turtle become a digital artist, I'd love for you to check it out: GitHub: https://ift.tt/wY6Egak Looking ahead, I’m also exploring frameworks like LangGraph and MCP (Modular Chain of Thought Planning) to see whether they might be better suited for more complex planning and decision-making tasks in robotics. If anyone here is familiar with these frameworks or working in this space, I’d love to connect or hear your thoughts.

Show HN: Hollow – A Customizable Digital Workspace
4 by ryu-suke | 0 comments
The project is a modular, fully customizable digital workspace designed for those who want complete control over their tools. Instead of being locked into predefined workflows, it lets you create, style, and organize tools as cards that seamlessly integrate into your workspace. - How the Project Works Tools - the app's core functionalities are it's tools, for example a notebook, kanban, webview... Limitless Customization - Styling the tools as i refer to each instance of it a 'card' is a another core feature, from minimalist setups to complex multi-card workflows. Plugin System - Extend functionality with plugins, making it adaptable to your needs, developer can use the app's api to make plugins/tools for the app. - Why This Project? Unlike traditional productivity apps, this project doesn’t force a specific structure. It’s an open-ended system where you build your own tools, layouts, and workflows instead of adapting to someone else’s design choices. Whether you need a note-taking space, a task manager, or something entirely unique, the project adapts to you. - Check it out: https://ift.tt/nxyd5bN Would love to hear your thoughts, ideas, or feedback! Thanks a lot.
