SIMULACRA
Hide among shades. Watch for hunters.
Simulacra is a small multi-node fleet that buries your real devices in a crowd of phantom shades — synthetic BLE and Wi-Fi devices that look like an ordinary crowd — and flags hunters: trackers and followers that shadow you across time and place. It runs on cheap ESP32 boards and shows what it sees on a small display.
Raise a fleet
You need at least one decoy board (ESP32-C5 or ESP32-C6)
and one controller (ESP32-2432S028, the "CYD" display). Plug in each board and flash
it — the chip is detected and the right role is installed automatically.
Before you begin. Works in desktop Chrome or Edge only (Web
Serial). This installs the baked starter build — every fleet shares one public key, so it is
for trying Simulacra out, not a private deployment; build the provisioned
regime from source for real use. A plain (non-CYD) ESP32 board would receive controller firmware, so
use the boards above.
