Carv

What it does

Carv is a digital ski coach that provides real-time audio instruction as you ski, powered by pressure and motion sensing inserts that retrofit to any ski boot. After 5 years of development, 10k skiers and 30m recorded turns, I'm pleased to announce Carv 4.0.

  I am building a free version of Strava2022 · mtbx.bike · ▲311

  I recently added a Segments feature to the Hangtime mountain biking app for Android and IOS. If you are familiar with Strava’s segments, this new feature works much the same. For example, you can add a segment to an existing recorded ride by simply defining a start and end point for the segment. Once the segment is created, it will match any new rides, and optionally “back match” all previous rides. If a segment matches a ride, you you will see your time to complete that segment as well as your personal record (PR) and king of the mountain (KOM) for that segment. The KOM represents the best…

  Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

  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:…
