Weather2Geo – Geolocate screenshots from weather widgets

Hi HN, I built an OSINT tool called Weather2Geo that helps locate where a screenshot was taken based on the weather widget data visible (e.g. temp, condition, and local time in the taskbar). People often post these without realizing how specific those values can be in combination. It works by comparing the given weather condition, temperature, and time against current data from thousands of cities. It’s timezone-aware, supports fuzzy matching, and groups results geographically to reduce noise. It’s most effective on recent screenshots, ideally taken within the last hour—since weather and…

In plain words

Weather2Geo is an open-source OSINT tool that identifies the location where a screenshot was taken by analyzing visible weather widget data, including temperature, conditions, and local time. It compares these details against current weather data from thousands of cities worldwide, using timezone awareness and fuzzy matching to narrow results. The tool works best on recent screenshots taken within the last hour and helps locate images lacking traditional metadata clues like EXIF data.

In the maker’s words, at launch

Hi HN, I built an OSINT tool called Weather2Geo that helps locate where a screenshot was taken based on the weather widget data visible (e.g. temp, condition, and local time in the taskbar). People often post these without realizing how specific those values can be in combination. It works by comparing the given weather condition, temperature, and time against current data from thousands of cities. It’s timezone-aware, supports fuzzy matching, and groups results geographically to reduce noise. It’s most effective on recent screenshots, ideally taken within the last hour—since weather and daylight conditions change quickly. The tool helps pinpoint likely locations when screenshots lack EXIF data or other traditional OSINT clues. It’s open source here: https://github.com/elliott-diy/Weather2Geo Would love feedback, bug reports, or to hear if you think this has other use cases. - Elliott

  • 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:…
