SURFBOARD LED STRIPS LIGHT UP THE WAVES

Surfing is an activity predominantly enjoyed during the day, primarily for reasons of warmth and water safety. Of course, if you prefer to carve the waves at night, you might enjoy the latest project from [Moritz Sivers] – a surfboard kitted out with motion-reactive LEDs. The build consists of a regular surfboard, with a channel cut around the perimeter into which WS2812B LED strips are glued. Powered by a ...

Monster Catcher Night Light

https://youtu.be/iJaVeIyJZwk This nightlight doubles as a trap to catch monsters under the bed! Before you go to sleep at night, place it under your bed and it will catch any monster under there. It even keeps a light on all night to make sure new monsters stay away. This Instructable makes a great project for parents of a kid who’s afraid of monsters under the bed. The trap can help them sleep easy knowing ...

STOP ‘N GO DUPLO

[beshur]’s 2-year-old is obsessed with transportation, so he lifted a few DUPLO blocks from the bin and made this toy traffic light as a birthday present. Hey, might as well get him used to the realities of traffic, right? It also makes for a good early hacker lesson: why buy something when you can make it yourself? The traffic pattern is determined by an Arduino Nano V3 situated inside the carved-out rear ...

A Christmas star with Neopixel LEDs

A tech Christmas decoration, created by means of Neopixel LEDs and controlled via an Arduino Micro board, that takes up a minimal amount of space. With the Xmas holidays approaching, we always try to propose a solution or another, one that is capable of combining tradition and innovation, so to avoid the usual or the trivial – even if always welcome – gadget, that is used as a Christmas decoration: and they ...

RGB LED Cube with Sound to Light Capabilities

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. [gallery columns="2" size="medium" ids="31240,31241"] The first part is the hardware setup that consists of the LED cube and the circuits that drive the power for each LED which is controlled through an Arduino Uno m ...

Smart Phone Controlled Arduino Mood Light with Alarm

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 colours I really loved watching these tiny LED’s changing colors so I decided to build somet ...

Researchers develop LED covering full visible light spectrum

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 evaluate those values, it is indispensabl ...

Fake TV Security Light

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 includes a power supply (no doubt of somewhat dubious quality and safety standards). So what follows is a fun project, but it’s eas ...

ESP8266 touchscreen WiFi light controller and clock

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 solutions (e.g., Philips Hue or Belkin WeMo), they do not require any p ...

World’s first light-activated, molecule-sized switch gets turned on

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. Unable to flick ...

Proximity sensor, gesture and ambient light sensing (ALS) module

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 time the light takes to ...
