Hello friends. We hope you are doing fine. The world is full of colours. Isn’t it? We humans can see and differentiate the colours very easily. But teaching robots and AI apps about colours is a real challenge. With the advancement of computer vision and embedded systems, this task has become easier than before. Today, we are going to make an RGB colour identifier using the ESP32-CAM. This project combines the power of OpenCV with the ESP32-CAM module to create a simple but effective system for detecting and tracking basic colors in real time.
System Architecture
1. Overview
This system consists of an ESP32-CAM module acting as a live-streaming camera server and a Python-based computer vision application running on a remote computer. The Python application fetches images from the ...
Hi friends! Welcome to another article in which we are highlighting the basic details of a gas sensor from the MQ sensor series. Today, our focus is on the MQ136 hydrogen sulfide gas sensor that instantly detects the presence of the sulfide gas and sends the signals through digital and analog pins to the output devices for timely indication.
Our mission is to understand the basic introduction of this sensor, so we’ll go through it and see the main points of its datasheet, such as its features and specifications. After that, we'll move towards the working principle and physical dimensions of MQ136, and consequently, there will be a discussion of the basic applications where this sensor is widely used. I am sure it is going to be a useful study for you, so let’s get started.

An action strategy is essential if you want to run corporate projects effectively. When you don't plan activities for the whole team, you won't be able to meet the set deadlines for completion or, worse, you'll exceed the pre-imposed budgets to meet the targets. So how do you manage project portfolios so everything goes according to plan? Use advanced business software!
Where do you start planning the implementation of corporate projects? It's not that difficult!
In practice, everything becomes easier when you implement advanced software tailored to your company's individual needs. Using a project management programme, you can freely plan activities, assign employees to specific actions, create reports and build project portfolios from scratch.

Hi readers! Welcome to this in-depth look at high-frequency PCB design. When dealing with radio frequency, microwave, or high-speed digital signals, you understand that the choice of material can ruin or redeem your design. FR-4 may be wonderful for typical-purpose PCBs, but it tends to lack in sophisticated applications. That is where Rogers PCB materials step in.
Rogers materials are laminates of high-performance that Rogers Corporation has made specifically for employment in RF and microwave circuit design applications. Their substrates contain low dielectric loss, reliable dielectric constants, and less moisture absorption. These characteristics are important for signal integrity, in particular, in high-frequency situations when even small changes can result in decreased performance.

A common requirement for technical professionals working on electrical projects is to understand wire sizing, including the differences that can apply to how this aspect is handled around the world.
One conversion that frequently needs to be made for electrical projects is from American Wire Gauge (AWG)
to square millimeters (mm2). The latter is a measurement of the actual physical area of the wire’s cross-section, known as the cross-sectional area (CSA).
The Background of AWG Conversions to Square Millimeters
The fact that wiring systems vary internationally – AWG being commonly used in North America, while many international codes stipulate that conductor sizes be specified in mm2 – means that if you are responsible for this aspect of a project, you will need to be vigilant in your ...
Hi readers! I hope you are fine and spending each day learning more about technology. Today, the subject of discussion is the ACS37030- high-bandwidth current sensors that enable high-performance power conversion in EV and data center applications.
The ACS37030 high-bandwidth current sensor is the answer to high-performance power conversion in Electric Vehicle applications and data centers. The precise current measurement with fast responses gives this a competitive advantage by allowing it to track electricity flow in real-time for proper power system working. With this high-bandwidth capability, it guarantees to measure rapidly changing currents and be very useful for applications involving dynamic environments like EVs, where demands for power change rapidly and quickly in data centers ...
You’ve likely seen this on the bench or in the field. A high-power LED build looks solid during testing but fails prematurely in the real world. The weak link usually isn't the driver or the chip; it’s the board itself. Standard FR4 boards act like thermal blankets, trapping heat exactly where it destroys the junction. If you’re pushing real power—anything beyond a simple indicator—an aluminum PCB isn't a luxury upgrade. It is an engineering necessity to protect your investment from the inevitable thermal load.
The Hidden Heat Problem That Destroys BuildsHigh-power LEDs generate intense heat in a focused surface area. Unlike incandescent bulbs that radiate heat outward, LEDs conduct it down through the package. Here’s the friction point: standard FR ...
Developer-first startups do not sell the same way traditional SaaS companies do. Their deals often involve technical champions, hands-on evaluators, product-led signals, engineering stakeholders, and buying journeys that start long before a demo request ever appears in CRM. That changes what revenue intelligence needs to do. It is no longer enough to summarize call transcripts, score pipeline movement, or surface generic sales activity.
What Makes a Revenue Intelligence Platform a Good Fit for Technical Sales
Not every revenue intelligence platform is built for technical GTM. Many were designed for broader enterprise sales use cases where the main value comes from forecasting rigor, call analysis, and CRM hygiene. Those features still matter, but developer-first startups often need more ...
