Last year we built a drone using ESP32 and our community loved it. Since then the project has evolved and the drone is now called LiteWing - think of LiteWing as a low cost development platform for Drones using which you can not only easily build and fly a mini drone but can also control it using python, add your own sensors or even write the entire drone firmware…
Want to boot your Raspberry Pi from USB instead of unreliable SD cards? If you've used a Raspberry Pi long enough, you've probably faced the dreaded SD card failure. Maybe it corrupted right after a power outage, or maybe it just wore out from thousands of log writes. That's when I finally decided no more SD cards. They're great for getting started with Raspberry Pi, but when you want…
If you've ever worked with a Raspberry Pi, you’ve probably run into that annoying moment when your Raspberry Pi just disappears from the network. You try to SSH into it or access a local web dashboard, but suddenly it's not there. You fire up the terminal and type ping raspberrypi.local, and nothing. It turns out, your router handed the Pi a different IP address this…
Building a DIY drone test rig is essential for safely testing mini-drones without the risk of crashes or component damage. This comprehensive guide shows you how to build a 3D printed drone testing stand that allows complete flight testing in a controlled tabletop environment. This drone test stand was originally built for our LiteWing Drones, but you can use it to test any mini drones.

Have you ever heard the word isolation, especially in electronics? As you might guess, isolation is a key factor when it comes to optocouplers. Isolation is sometimes mandatory and sometimes an extra feature in circuits. Optocouplers are used in many electronic devices, from mobile electronics to household electronics.
So, in this…
The world of printed circuit board (PCB) design is changing fast and artificial intelligence (AI) is one of the major players in that transformation. With the arrival of AI-powered design tools, many are wondering if these technologies will eventually make the traditional role of PCB engineers obsolete. Let’s break down how AI is impacting PCB design and…
In the busy industrial city of Coimbatore, India, a company has been quietly transforming the way we think about motor control and energy efficiency. Versa Drives Private Limited, founded in 1989 by Durga Krishnamurthy and Sundar Muruganandhan, has grown from a small partnership firm into a prominent leader in custom motor control solutions. During an exclusive…
Current transformers play an important role in protecting electrical systems. They are primarily used where a current is too high to measure directly such as power plants, grid stations, etc. These transformers convert high alternating current into a smaller value that can be safely measured. If you want to start with more basics you can also check out our article on…
Have you ever remembered the loud roar of an old diesel train? In the past, when a train sped along the tracks, you could hear its deep rumble from far away. The sound of the engine, the shaking of the carriage and even the scent of diesel made every journey an adventure to treasure. Today, when you step onto a modern train you may hardly notice any noise at all. The…
This guide covers flying the LiteWing drone using the latest LiteWing Mobile App. The new app supports both Android and iOS devices and includes enhanced features like Height Hold mode, battery monitoring, emergency stop, and improved flight controls. The app is based on the Crazyflie 2.0 protocol and supports not only LiteWing drones but also other mini drones that use the…
Selecting the right battery for LiteWing is key to getting stable flights and longer airtime. Because LiteWing is a small, WiFi-controlled drone powered by an ESP32-S3, its battery needs to strike the perfect balance between power, weight, and discharge rate. The drone comes with an out-of-the-box 1S 3.7V 30C battery, but if you're looking to upgrade, we'll guide you through key…
Drones, also known as unmanned aerial vehicles (UAVs), have evolved into essential tools across multiple industries. Their diverse designs and flight mechanisms cater to a wide range of applications, from personal hobbies to military operations. Understanding the different types of drones helps in identifying their specific roles and advantages. Based on the design,…
