A virtual race car that drives only while someone pays for fuel
A race car drives for as long as someone pays for fuel. $1 = 1 kilometer and 60 seconds of your livery on the car. Goal: one lap around the Earth.
What it does
Minimum $2. 2 km on the odometer, and 2 minutes with your logo and colors on the car. Your name, one line about what you do, and a link out. It goes into the sitemap and it stays there. Your time on the car runs out. The page does not come down with it. Body, wing and flank repaint the moment your window opens, with your logo where a real sponsor logo would sit. That is the part worth screenshotting, and it is on the page everyone lands on first. Money buys length here, not priority. Whoever pays first drives first, so a $500 order cannot push you out of your window. It waits behind you and then drives for eight hours. Every order gets opened and read before it reaches the car: the domain,…from fuelup.lol

Each dot on the chart is a car. Horizontal scale = mileage. Vertical scale = price. The size of a dot = year (newer = larger), plus I colored 2007 .. 2011 in different colors to find "fresh" cars quicker. This is just some sample data from the last 24 hours, relatively cheap cars under $32,000 within 500 mile radius of NYC.

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.
