Speech recognition models like OpenAI’s Whisper offer high levels of accuracy, but their base model itself consumes up to 140MB and running them on a low-end device like an ESP32 is difficult. In this tutorial, we are going to run Cactus Compute’s Whisper Speech-to-Text Model launched on 2nd of October 2026. The actual size of the model is 16.9MB, which won't fit…
Murali Srinivasa, CEO and founder of Lion Circuits, says India can compete with China in PCB manufacturing, and that significant change will be visible in four to five years. He also explained what stands in the way.

These days, we are heavily dependent on cloud computing, high-speed internet and all. We rarely think about what happens if the internet goes down or what happens in areas where the network is not reachable or information access is very difficult. The main solution is having the data and its processing locally so that they are reachable anytime, even without internet…
At electronica India 2026, STMicroelectronics showcased a range of robotics and embedded AI solutions, with one of the highlights being a 6-DOF robotic hand controlled by AI-based gesture recognition. Developed by a robotics customer using ST microcontrollers, the demo used a camera to capture hand movements and an AI system running on the STM32N6 to recognize…
Semtech’s Robert Comanescu, Vice President of R&D and Applications for Wireless ICs, and Tamir Reshef, Vice President of Products and Applications for the Analog and Mixed Signals business unit, discussed the challenges of building IoT devices that communicate reliably and withstand real-world conditions at electronica India and productronica India 2026 in Bengaluru.

Kikobot Robotics is an early-stage hardware startup in Pune. It began by building robotic arms for education and research and has since moved into industrial-grade arms and its own actuators. Raghvendra says the company builds robot arms for education, research and physical AI, and arms for industrial use cases as well. The lineup includes cobots, delta robots and gantry systems.

As part of our India Tech Tour series, we visited Peer Robotics' facility in Pune, where Ritwik walked us through the company's robots, manufacturing setup, and engineering processes. We also spoke with Ruchit, Vice President of Software Engineering at Peer Robotics, about the company's approach to deploying autonomous mobile robots in industrial environments.

Sub-1 GHz radio links sit at the core of a wide range of products, including public safety radios, smart utility meters, RFID readers, and vehicle telematics units. Many of these systems now need to work across several regional frequency allocations without a hardware redesign for each market, while still running efficiently on battery power in a compact footprint. Qorvo's QPA9510 power…
We are all facing a huge transition in tech due to AI. In projects, we can run AI models on PCs, SBCs or even Cloud servers. In this tutorial, we are trying to see if we can run an AI model on a microcontroller board like the ESP32. To test this out, we are going to deploy and benchmark the 260K-parameter Tiny-LLM by Andrej Karpathy using his open-source llama2.c…
ROS 2 has become one of the most important technologies for engineers interested in robotics. But beginners often struggle with the same questions: Should I learn ROS 1 first? Do I need a physical robot? Which programming language should I know? And is ROS actually used in production?We discussed these questions with Shubham Nandi, co-founder and Chief Research…
ESP32 Cameras have become a popular choice for building low-cost wireless cameras, smart surveillance systems, and even small AI projects. But today, there are several options available, from the original ESP32-CAM to newer ESP32-S3-based camera boards and compact boards like the XIAO ESP32-S3 Sense. At first glance, they may look similar, but there are…
ESP32 development boards have been around for years, and we all have been doing a lot of projects with them. They come in various models, with different peripherals, and they perform different levels of tasks. If we are to check into a simple example, we have the normal ESP32 WROOM development boards as well as the same ESP32 with a camera sensor mounted onboard, the…
