How it Works
A given object is placed on the Elemental Scanner, it analyses its chemical composition and throws up the result, displaying its major element and the star that element came from.
A concealed RFID chip was placed in each object (A) The Tracer itself was comprised of a computer (B), a custom designed PCB which integrated an Arduino and an ID 20 RFID Sensor (C), It also had two arrays of LED’s (D). When the object is placed on the Tracer, it triggers the LED arrays (D) to produce feedback of analysis. Then, based on each unique chip, identified by the RFID Sensor (C), the relevant information is retrieved and displayed by a Processing sketch, and shown on the Display.
