2 Community mentorship & ground‑rules keep repairs thriving “We did have to set some ground rules: (clean your fan/vac, bring batteries, etc).” — washbasin
3 Centralized knowledge & part libraries are needed “A lot of repair knowledge is buried in non‑English forums or unsearchable Discord servers... We need to localize it and rebuild community expertise.” — kayson

Core Feature Geo‑based meetup discovery, calendar scheduling, and resource sharing (PDFs, videos)
Tech Stack React front‑end, Node.js/Express API, PostgreSQL, Mapbox geolocation
Difficulty Medium
Monetization Revenue-ready: Subscription $5/month per group

Notes

  • “We have at least one in Portland, and they do both clothing and electronics repairs. It's great to see a repairability movement!” – would love a tool that surfaces such groups automatically.
  • Potential for practical utility: helps users find existing meetups, start new ones, and share repair tips, addressing the “Is anyone in Austin TX starting one up?” question.

Notes

  • “A related idea I had was a library of 3d models of parts… My thought was if it's plastic you could 3d print whatever little busted plastic part…” – directly solves that need.
  • HN would value a curated, searchable component database that replaces scattered Discord channels.
