TimberSentry
See decades of land change from satellite, before you buy
What it does
TimberSentry turns public Landsat and NAIP satellite archives into a property-specific historical report. Draw your land's boundary, and see quality-screened imagery from 1984 to today — clearing, regrowth, and canopy change, organized into a source-cited PDF, MP4 timelapse, and GIS-ready package. Built for land buyers, foresters, and rural real estate due diligence. Free to search; reports start at $29.
Generate historical satellite land change reports for $49. Preview a property-specific Landsat/NAIP web report, print or save it as PDF, and receive an MP4 and GIS-ready ZIP. No subscriptions.
TimberSentry saves hours of finding, screening, clipping, comparing, and organizing historical imagery—so you can review decades of property history without doing the manual GIS work or hiring a GIS consultant. Draw a polygon on the map or upload an existing Google Earth boundary. KML and KMZ polygon boundaries up to 5 MB. Non-polygon placemarks are ignored. Historical catalog from 1982 to present. Supported area: more than 250 acres and up to 5,000 acres. Free search only - no account and no payment. *Actual coverage varies by location and source. See which dates and sources are available, compare seasonal consistency, and open individual public source records. Property-specific…from timbersentry.com

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 OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
