The Approach
We started with a forensic review of instructions, understanding the software functionality (by trial) and interrogating CE/FCC information about the history of the hardware. In order to evaluate the functional performance, we conducted technical tests for each of the products. We then disassembled the products to extract the hardware and created a costed Bill of Materials (BOM) for each. We analysed the PCB construction and the key electronics components, identifying device operating principles, implications for manufacturing, relative design choices and the comparative technical advantages of each device.
