Voice control has become an integral part of modern smart home automation. In this tutorial, we build a voice-controlled LED system using the ESP32-S3-BOX-3 development board, combining wake word detection, speech recognition, touch interface, and audio feedback to create an intelligent control system. The code will be based on the factory example provided by…
Years ago, if you had opened the door to the hostel room of Venkat Rangan, you would have been greeted by music. One could say tinkering was something he always latched on to, because the door’s latch triggered the music from a system he built himself. "He's always been a tinkerer," recalled Vishal Srivastava, who studied alongside Venkat and now leads Marketing and Business Development at the…

Eventually, the company added BLDC motors, propellers, Electronic Speed Controllers (ESCs), Power Distribution Boards (PDBs), and DC-DC converters to its catalog. “We just listened to the customer…
Understanding Vicharak starts with the Von Neumann Bottleneck. To those unfamiliar, in short, it’s a fast computer wasting time waiting on memory delivery. At a slightly technical level, dated implementations of the Von Neumann architecture involved moving data between the processor and memory through a single bus, which forced instructions and data to compete for bandwidth. This meant that…
A robotic arm is one of those classic projects that almost every electronics enthusiast tries at some point. It’s a perfect mix of mechanics, electronics, and hands-on creativity and building one teaches you more than any textbook ever could. When most people think of robotic arms, they picture the big, ultra-precise industrial robotic arm machines found in factories…
