This lecture presents the Makers' secrets, or how you can take your gadget idea and build it at home. I'll give step-by-step: how you can design an electrical system for a System-on-a-Chip IoT device and sensors, manufacture the electrical circuit board, solder the SMD components, design the 3D-printed device box, develop the embedded software, develop the cloud backend software, and have an end-to-end device connected IoT system, all at your home office.
