EL Wire (Electroluminescent Wire) Basics For DIY Works

EL wire is wire which glows without LED. We can control EL Wire through an Arduino or ESP32. These are thin copper wire coated in a phosphor which produces light when AC is applied to it. AC does not mean home supply AC - battery with inverter enough for them. They can be used in a wide variety of projects much as custom neon lights were often used. The thin diameter EL wires make them flexible … [Read more...]

Traffic-Sign Recognition : Basics

Traffic-Sign Recognition (TSR) is a part of Advanced Driver-Assistance Systems (ADAS). Traffic-Sign Recognition (TSR) helps the vehicles to recognize the traffic signs on the road. The signs can be speed limit, school children, turn ahead, speed breaker and so on. The Traffic-Sign Recognition systems are increasingly being used for road traffic safety by helping the drivers by automatic alerts on … [Read more...]

Uses of Text Mining in Web Content Mining : Part IV

In the third part of Uses of Text Mining in Web Content Mining, we informed that in this part we will discuss about the areas of application or tasks of text mining. Basically, the different methods should analyze texts and make the implicit information too explicit. Then form relations from the information in different texts, highlight and visualize them. The descriptions give an overview of the … [Read more...]

DevOps and Agile: What Are the Differences?

In our previous series of articles on DevOps, we stated that the aim of the collaboration should be to use the agile principles of software engineering across departments and thus to derive added value from the cooperation. While DevOps and Agile are two different things, they are often mistaken for one another. In reality, the two represent different approaches or practices in developing … [Read more...]

2-in-1 convertible laptops vs Android Tablets

2-in-1 laptops have a screen which flips back 360 degrees. The screen can be detachable, which makes hybrid of tablet and desktop and the rest 2-in-1 laptops have a screen that flips off, providing a tablet experience and commonly named as “convertible”. Unless desktop computers are in consideration, 2-in-1 convertible laptops with 14 inch and 15-inch screens are of definite attraction. There are … [Read more...]

Uses of Text Mining in Web Content Mining : Part I

English philosopher Francis Bacon said "Knowledge is power". It is still as true today as it was almost 420 years ago. However, in the past, it has always been associated with luck or tremendous diligence to acquire this knowledge, so we are experiencing a true heyday in recent years due to technological advances. In the past, if you had to roll over tons of books or spend enormous amount of … [Read more...]

ESP32 Relay Control : Shift 3.3V Signal to 5V Signal

In our guide on Controlling AC Powered Appliances With ESP32 and IBM Watson IoT we pointed that the relay connected with ESP32 may not properly function. There are many ways to shift the 3.3V signal to 5V signal. A level shifter or logic-level shifter is a circuit used to translate signals from one logic level or voltage to another. The logic-level shifter can be uni-directional, … [Read more...]
