Voice control technology has become an important part of modern human-machine interaction. It allows users to control electronic devices and systems using simple spoken commands instead of traditional input methods such as buttons, switches, or touch screens. This type of interaction makes devices easier to use, more accessible, and more convenient in many…
In conversation with Bhupinder Singh, President – IMEA (India, Middle East, Africa), Messe München | CEO, Messe München India
Q: India’s electronics narrative has clearly shifted. What, in your view, is the defining change in the market today?Bhupinder Singh: The defining shift is from intent to execution—at scale. Capacity is scaling, compliance is tightening, and decision cycles are…
Pace Robotics makes robots that paint… just not something you’d hang up at a gallery. As a part of our visit to this Bengaluru-based startup, we got to witness one of those robots in action at an actual construction site. They call it the Centa Painter, and it can spray putty, perform sanding, and apply paint on interior walls and ceilings, all things humans have been doing by hand forever and…
We love tinkering with our LiteWing ESP32 drone, and this time we gave it a simple but exciting upgrade, a WiFi camera module! With this addition, the drone can now stream live video while flying, perfect for hobby flights, aerial experimentation, or just having fun seeing the world from above.
On the technical side, the setup…
From STEM classrooms to early-stage startups, the LiteWing Drone has found its way into the hands of students, makers, and engineers alike. Our goal with Litewing was to build this very same ecosystem by keeping the hardware open and affordable, with software that is scalable and beginner-friendly. After the launch of the LiteWing Drone Positioning Module, we noticed a lot of people wanted to…
“Everything starts with the product definition,” is how G. S. Madhusudan, CEO and Co-Founder of InCore Semiconductors, began walking us through the complex web of players that bring a chip to life. Given that we were on a Google Meet, he picked an IP camera chip as his example, because it essentially functions the same way. The list of things this chip does includes
Interfacing with…
In this project, we upgraded LiteWing, an ESP32-based development drone by adding a lightweight Bluetooth speaker system to extend its capabilities beyond flight. By adding a simple Bluetooth audio setup, the drone can now deliver real-time announcements, voice messages, or music directly from the air without requiring any additional coding. The entire system works…
FPGAs have become a recurring subject in recent CircuitDigest features, appearing in themes of education and accessibility. In our interaction with Krishna Gaihre, CEO & Founder at LogicTronix, an "AMD-Xilinx’s Selected Partner (ACP) for FPGA Design and ML Acceleration," we explored the practical side of things. Before getting into anything about the company, it’s worth taking a step back…
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…
DTDS’s booth at electronica India 2025 highlighted a cost-effective approach to vehicle lighting systems. The company stated that its Light Control Module offers a competitive advantage, being 25% lighter on the pocket when compared to other market options. Chand Hanif, Senior FAE at the company, walked us through a live demo of the module at the booth. He explained, "We have put that complete…
