Zeitkastli

A weatherproof capsule and a web app that remembers where you put it.

Not running yet

Problem

People put things away on purpose to be found later — a letter to a child, a keepsake, a class time capsule — and then lose the exact spot. Memory is the part that fails, not the box.

Solution

A weatherproof capsule plus a web app that records the spot: a map pin, a photo of the place, notes, and the person it is meant for.

Mission

Make sure something you put away on purpose can still be found by the person it was meant for.

Vision

The ordinary way to leave something behind for later — and to still be able to find it.

Technical context

The stack has not been written down yet.

Changelog

  1. September 15, 2026

    Renamed HamsterCheek to Zeitkastli and reframed the product as a time capsule. The old framing (storing valuables outside homes and banks, stashes, off the grid, hide it anywhere) read as asset concealment in a public repo. Renamed the GitHub repo and rewrote its description, renamed stashes to capsules across schema, routes, types and copy (drizzle 0001 renames the table rather than rewriting history), and rewrote the bitbaum brief, the fleet origin register and the public loki test fixtures.

  2. August 5, 2026

    Added the missing delete-a-capsule flow (server action removes the DB row + its uploaded photo, wired to a confirm button on the capsule detail page); verified against the real Postgres DB end-to-end and confirmed `npm run build` + `next start` serve the page correctly.
