Charm Checkout Counter - Remote retail ops with 412x412 + Vision AI. Small store owners in Ecuador can't monitor checkout queues when they are away. This project turns a $20 gadget into a remote ops center. Owner anywhere says to his Charm (Muse Gadget, 412x412 OLED, 5G, no phone needed): "chequea la caja ahora". The Linux gadget in the store (Mac mini / Raspberry Pi on store WiFi) receives the command via Muse cloud, runs YOLOv8 + SAM 3.1 on the last 2 min of real CCTV footage (validated on YouTube retail CCTV), detects cashier presence and people in queue, and returns to the Charm screen: "SIN CAJERO / 14 FILA LARGA" -> "CAJA ACTIVA / 2". Solves: theft, long queues, cashier no-show. No video sent to cloud, only JSON result. Built and tested with real store footage. Previous idea was habit tracker, pivoted to retail counter - this is the final version.
