Live alerts on the Tesla screen
What it does
A community navigation companion for the Tesla browser. Live alerts, charger intel and route notes — called like a rally codriver in the right seat. Built by Tesla drivers, for Tesla drivers.
A community layer that runs next to your Tesla nav. Always one corner ahead. Magic link, no password. Your spot on the launch grid comes up in an hourly start — or a friend fast-tracks you. Pair the car with a QR scan from your phone — no typing on the car screen. Pin the tab and it's installed. Alerts and chargers appear live as drivers post them. No app, no firmware wait, no update to install — ever. Pace notes called in tight cadence. Distances over adjectives. “Cop. 800 m. Right bend.” The car stays yours; the layer stays out of the way until it's the moment to know. Same map, four perspectives. Free unlocks Compass — north-up, for familiar roads — and Track, which turns with you…from codriver.io

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
