The objective of our final project was to build a 5x5x5 RGB LED cube that can display a certain color depending on the frequency of music playing. There are two main components of this project. The first part is the hardware setup that consists of the LED cube and the circuits that drive the power […]

Smart Phone Controlled Arduino Mood Light with Alarm I recently purchased the Neo Pixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL), is becoming more common as the next generation lighting. Evaluations of total luminous flux (a performance index for lighting) and color are important for SSL, and to

Update: Looks like somebody had this idea before me and made a product out of it. Just Google Fake TV. In fact, you can also buy a clone of this from AliExpress – again, just search for ‘fake tv’ in AliExpress. The Chinese versions can be had for about $12 in your hand and that

A couple of months ago I picked up cheap WiFi-controlled LED bulbs (one among dozens of very similar devices), after seeing them at a friend’s place. This turned out to be an excuse to play with the ESP8266, which has inspired several hacks. I was overall very happy with these bulbs: decent Android and iOS apps and, compared to fancier

In the pursuit of ever-shrinking circuitry for nanotechnology electronics, increasingly smaller devices and components are being developed. Now researchers at the University of Konstanz and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany claim to have micro-miniaturized the humble electrical switch all the way down to molecule size and proven its operation for the very first time.
World’s first light-activated, molecule-sized switch gets turned on Continue Reading
The VL6180X is the latest product based on ST’s patented FlightSense™technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL6180X precisely measures the
Proximity sensor, gesture and ambient light sensing (ALS) module Continue Reading
Every year I notice that I have little issue waking up at 7am during summer months, yet waking up at 8am during winter is always unpleasant. Some quick research led me to find that the body is gradually woken up by light, which is why products such as the Phillips Wake-Up Light exist. However, with

In this Arduino UNO tutorial, we are going to use a Light Dependent Resistor (LDR) to create a simple childrens bedroom nightlight which turns on automatically when it gets dark and turns off when it gets light. An LDR’s resistance changes depending upon the amount of light hitting the sensor. For the LDR we are

Based on 1.1-µm pixel technology, the AR1335 CMOS image sensor from ON Semiconductor provides 18% better sensitivity than previous-generation devices, along with increased quantum efficiency and linear well capacity to enable near-digital still-camera quality and low-light imaging on smart-phone cameras. The sensor’s pixel and color filter processing increase sensitivity, allowing more light to be captured
