Alive

What it does

Alive is a lightweight safety status tool for people living alone. Unlike location/social tracking, it’s almost invisible: set a check-in timer and tap once daily; if time runs out or check-ins are missed, it auto emails tiered alerts to your emergency contacts. It’s instant to start (no sign-up), no location, minimal permissions, no irrelevant data. Contacts and logs are encrypted. Customize period, grace, reminder cadence, and quiet hours. Silent when you’re fine, loud when you’re not.

  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:…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http:&#x2F;&#x2F;cannoneyed.com&#x2F;projects&#x2F;isometric-nyc
