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a solo project for now, inspired by the “second brain” / PKM movement and my own frustration with fragmented tools and outdated UX.
