## What it is
A Go/TinyGo library and toolset for tracking personal Bluetooth devices through Apple's Find My network, using OpenHaystack and Macless-Haystack without requiring Apple hardware. It includes beacon firmware for microcontrollers and embedded Linux, plus TinyScan, a hardware scanner for local devices.

## Use cases
- build my own airtag-like tracker without apple hardware
- track bluetooth devices via apple find my network
- flash findmy beacon firmware onto nrf52 microcontroller
- run a find my beacon on a raspberry pi
- scan for nearby findmy beacons with a tiny display device
- set up macless haystack endpoint with docker

## When to choose
- you want to leverage Apple's Find My network for custom trackers without owning Apple devices
- you have TinyGo-compatible Bluetooth hardware like nRF52 boards or a Raspberry Pi
- you prefer Go tooling for beacon firmware and scanning

## When to avoid
- you need a polished consumer product rather than DIY firmware and Docker setup
- you cannot use an Apple ID with SMS-based 2FA, which is required for setup
- your hardware is not supported by TinyGo Bluetooth or lacks compatible Bluetooth co-processors
