Can Strava Do This?
I recently added a new feature to the MTB Hangtime app that allows users to generate a telemetry overlay on top of an action camera video. The demo video was created using only the app, no third party video editing tools. The goal was to be able to capture the telemetry data with a smart phone and the video with a GoPro, then generate the output video without any additional tools.

I have been working on a new mountain biking app for the last year called Hangtime. It is a free ride computer app that uses a smartphone's GPS, accelerometer, gyroscope, and altimeter to track a mountain bike ride. After recording a ride, the user can go back and see their performance in turns, jumps, climbs, etc. Below is a video that shows off some of the app's features. https://youtu.be/TXiwzf-UJhQ I wasn't sure I could get the performance required from Flutter/Dart vs. native as a one hour ride generates well over a million data points from all of the sensor data.…

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:…

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
