Fairchild Simplifies Dimmable LED Lighting Design

Electronics News Updates / By Ibrar Ayyub

Single-Stage Primary-Side-Regulation PWM Controller for PFC and Phase Cut Dimmable LED Driving The FL7734 is a highly integrated PWM controller with advanced Primary-Side-Regulation (PSR) technique to minimize components for low power LED lighting solutions. Using the innovative TRUECURRENT technology for tight constant-current control, it enables designs with constant-current (CC) tolerance of less than ±1% in […]

Electronic Circuit Designing: Multitasking with Circuits (Part 4)

Electronics News Updates / By Ibrar Ayyub

Step: 8) Find reusable modules from the circuit diagram Whenever we do hardware designing, the first rule is to make it in modules that can be reusable. The modules that we make for this particular project may come useful in another project and hence reduce the development time for that project. Even if a module

Soil sensor mini kit shows if plant needs watering

Arduino News / By Ibrar Ayyub

Adafruit Circuit Playground Express Soil Sensor Mini Kit is designed to measure the soil moisture content. This kit, available now from Mouser, is based on the Circuit Playground Express platform and delivers the measurement utilising a nail and alligator clip. As the moisture encompassing a nail in the plant pot rises, the board detects the

DEAD BUG ARDUINO IS LIVELY AND SHIELD-COMPATIBLE

Arduino News / By Ibrar Ayyub

Microcontroller demo boards such as the Arduino UNO are ubiquitous on Hackaday as the brains of many a project which inevitably does something impressive or unusual. Sometime someone builds a particularly tiny demo board, or an impressively large one. In the case of the board featured here, the Arduino is a gorgeous labor of love

Using NXP’s NXQ1TXH5 Qi Charging Circuit

Electronics News Updates / By Ibrar Ayyub

Adding wireless charging to furniture and other consumer goods is a nice way to add some oomph to an otherwise boring product. NXP’s NXQ1TXH5 provides an interesting, albeit difficult-to-prototype way around the problem. Creating a Qi-compatible is as easy as assembling the example circuit shown in figure one. From a technical point of view, the

Electronic Piano

Sound – Audio Project Ideas / By Ibrar Ayyub

In this project, we will learn how to use an Active Buzzer and a 4Duino to create an Electronic Piano. An active buzzer is an electric piezo device which is commonly used to produce sound. When subjected to an alternating electric field, a piezo ceramic material disc inside the buzzer is caused to stretch or

Cheapest PCB (circuit board) prototyping

Blog / By Ibrar Ayyub

What is a PCB? In common we can define PCB as the flat sheet of material that supports mechanically and electrically connects electronic components using conductive tracks, pads, and other features that are etched from a series of copper sheets that have been laminated onto a non-conductive substrate. This substrate varies from a cellulose-based material,

HTML5 Circuit Simulator

Electronics News Updates / By Ibrar Ayyub

This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It’s very helpful for experimentation and visualization. Best of all, thanks to the power of HTML5, no plug-ins are required! The original implementation, in Java, belongs to Paul Falstad who kindly gave his permission for me to build this port.

Arduino Based Digital Clock with Alarm

Clock – Timer Project Ideas / By Ibrar Ayyub

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is reconnected, it displays the real time irespective to the time and duration it was in off state. In this project we have
