NEW DIMENSION OF BRIGHTNESS: OSRAM HERALDS A NEW CHAPTER FOR LED PROJECTION

As projectors grow more and more popular in home entertainment systems, so have the expectations of users. In addition to ever-higher resolutions, the focus is also on richer colors, contrasts and, of course, higher brightness. With the Ostar Projection Power family, Osram has succeeded for the first time in achieving projector brightness levels beyond the […]

LED Fader – With or Without Arduino

LED Projects / Tismail

Have an awesome project in mind using some LEDs. In that project I will be using some LED Fading Effect and few LED Chaser Circuits. But before jumping onto that, I thought I should create a short tutorial and show you guys how to fade a LED with or without an Arduino automatically or manually

TINYOSD & TINYFINITY – A TINY OPENSOURCE VIDEO TX WITH FULL GRAPHIC OSD

Electronics News Updates / Ibrar Ayyub

Merry belayed Christmas and a happy new year everyone. I know, I am running a tiny bit late. My original plan was to release the tinyOSD and tinyFINITY sources ready for Christmas but then the usual things got into the way and I had to postpone this post. But here it is: I am releasing

ARDUINO CLOCK ON IN-18 NIXIE TUBES WITH A LONG SERVICE LIFE

Electronics News Updates / Ibrar Ayyub

Build your own Nixie tube clock/thermometer/display with ease. Story We set out to create a Nixie clock or just an information indicator on the largest ex-Soviet IN-18 tubes as an Arduino shield-compatible with both Uno and Mega boards. After a long reading of lots of information about IN-18 tubes on the Internet, we found out

The New Light-responsive Nano LEDs

Electronics News Updates / Ibrar Ayyub

A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in the paper, they included quantum dots

Tibbo Project System-based Aircon Controller Application

Electronics News Updates / Ibrar Ayyub

The app allows you to manage traditional air conditioners that are controlled through infrared remotes. Designed for the office environment, the app relies on the ambient brightness (measured by Tibbit #28) to determine whether the aircon should be running or not. In the office setting, no lights = no people = no need for the

4Duino LED Brightness Control

Arduino LED Project Ideas / Ibrar Ayyub

In this project, we will learn how to control the brightness of LED via an I/O port (with PWM output capability) and a touch display slider. The 4Duino resistive touch display is used as a means for a graphical interface to control the intensity of the LED. Since the 4Duino itself has an LED on

PWM with Arduino Due

Arduino LED Project Ideas / Ibrar Ayyub

Arduino Due is an ARM controller based board designed for electronic engineers and hobbyists. ARM architecture is very influential in modern electronics, we use them everywhere like our mobiles, iPods and computers etc. If someone wants to design industrial systems it must on ARM controllers. ARM controllers are very important because of their agility. We

Measure small LCs with a scope

Electronics News Updates / Ibrar Ayyub

One of our technicians recently asked for help determining the value of an SMT inductor. It was unmarked, and was many turns of very fine wire on a ferrite core. The resistance measured 26Ω, which for some reason gave our ancient LCR bridge a conniption, and read 30mH along with a blinking error message. The
