Imagine you've just sent a parcel through a courier service. As soon as it leaves your hands, you start wondering what is happening to it. Is it being handled carefully? Has it been dropped or damaged? Is it still on the right route? Will it reach the destination safely and on time? The truth is, once we send a parcel, we have very little idea about what happens…
Modern server and data center design places increasing demands on the physical interconnect layer. At 112 Gbps and beyond, connectors are no longer treated as simple passive components; their design has a direct impact on crosstalk, impedance continuity, and mechanical integrity across the system. The following provides a technical overview of four Amphenol interconnect product families…
This DIY tutorial is all about making our home lighting smart and fun without any complicated steps. We can connect a standard 12V LED strip to a tiny wi-fi chip and build our own ESP32 WLED controller custom smart lighting system, which can be completely controlled from a smartphone or computer.
This DIY ESP32 based WLED controller…
A fab lab, short for fabrication laboratory, is a digital fabrication workspace rather than a traditional hand-tool workshop. The concept originated at the MIT Center for Bits and Atoms, where professor Neil Gershenfeld conceptualized and scaled the idea into an entity called the Fab Foundation. Gershenfeld drew inspiration from a visit to Pabal, near Pune, where Dr. Kalbag was building a…
The new 100-acre Terra Circuits campus aims to significantly expand India’s PCB manufacturing capabilities, with first production targeted for mid-2027.
LionCircuits has announced plans to invest ₹441 crore in establishing Terra Circuits, a 100-acre PCB manufacturing mega campus in Mulvad, Vijayapura district, Karnataka. The facility…
Bandwidth requirements in data centers, edge computing, and industrial automation are rising faster than the board space available to support them, and the equipment running these workloads often has to keep performing in conditions that are anything but gentle. That combination puts unusual strain on interconnects, which is precisely the segment TE Connectivity is targeting with its 56G…
At electronica India and productronica India 2026, Aswinth Raj, editor of CircuitDigest, sat down with Sameer Jain, co-founder and director of business growth at Brandworks Technologies, to discuss India's transition from electronics assembly to design-led manufacturing.
What Design-Led Manufacturing Actually Means
Sameer defines design-led…
At the recent Electronica 2026 expo, I had the chance to spend some time at the Quectel booth speaking with Vijay Prakash (Product Manager, Quectel) and exploring their latest lineup of AI-focused single-board computers and smart compute modules. Most of us are already familiar with popular SBC platforms like Raspberry Pi and NVIDIA Jetson boards from NVIDIA. Quectel is now entering this space…
When Shailesh Kachi, Founder of Adevair Technologies, set out to build Securio, he found the market fragmented. There were AQI monitors that showed how bad the air was but did nothing about it, purifiers without awareness of local air conditions, and filters that didn’t know when they were worn out. He wanted something different…something unique…one could say a breath of fresh air.
And…
Agam Robotics is a startup based in Bangalore that builds drone components, including flight controllers, GNSS modules, optical flow sensors, rangefinders, power distribution boards, and power modules. The company's stated focus is on building products from the bottom up within India, with PCB fabrication, assembly, enclosures, plastics, and aluminium heat-sink components all done in India.…
If you are working on IoT projects, you already know the importance of an M2M IoT SIM card for remote monitoring and tracking. For those who are new and wondering why you need a special M2M SIM card when you can just use your normal SIM card, here are two strong reasons to consider one.
Cost: If you are running a…
In this tutorial, we are going to see how you can create a custom Graphical User Interface(GUI) using LVGL and our favourite Arduino IDE. You can use any kind of microcontroller for this project; the only thing you need to do is to include the right pins in the Arduino code. Here, I’m using an ESP32-C3 based smartwatch for the demonstration. This has a display, touch, controller and…
