Learn how to build a wireless stepper motor controller using an ESP32-S3 and TMC2240 driver. This detailed tutorial guides you through wiring, custom PCB design, USB-C PD power management, closed-loop control with an AS5600 encoder, and a browser-based UI with real-time status and RGB feedback. Includes Gerbers, BOM, and full source code.

Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million)

Virtually every electronic product is constructed with one or more printed-circuit boards (PCBs). The PCBs hold the ICs and other components and implement the interconnections between them. PCBs are created in abundance for portable electronics, computers, and entertainment equipment. They are also made for test equipment, manufacturing, and spacecraft.
