Cree LMH2 LED Module Versus Traditional CFL Options By Digi-Key Technical Content Contributed By Digi-Key Corporation The Cree LMH2 LED Module provides unparalleled efficacy and light quality in a fully integrated module. Utilizing Cree’s True White Technology, the LMH2 provides beautiful 90 plus CRI lights in 4000 Kelvin, 3500 Kelvin, 3000 Kelvin, and 2700 Kelvin […]

While most of the knowledge about tiny snails comes from studying empty shells sifted out from piles of dust and sand, the present research is the first contemporary microscopic exploration of organs in cave snails tinier than 2 mm. The paper, published in the open-access journal Subterranean Biology, reveals that underneath the seemingly fragile shells of the Zospeum genus, there are strikingly huge organs.

In this step by step I wanna share my experiment with ATMEGA128 timer and interrupt using DS1307 and NTC to display homemade clock and thermometer. It displays hour,minute,second, day of week, day of month, month, and year, and the temperature in celcius Enjoy the project… Step 1: Prepare all the parts for this project This […]

Description RGB LED disco light is a simple project designed around PIC16F72 microcontroller. This firmware is a RGB driver, as name suggests it is used to derive or light red, green and blue LEDs in particular fashion. Its main feature is the pattern shown on LEDs. It is quite difficult to describe pattern in words […]

I’m working on a project that requires full orientation information, so I built an Inertial Measurement Unit from scratch. I really like the 9DOF IMU board that Sparkfun makes – the calibration code that comes with it is fantastic – but I wanted to redesign the board so that it could be made at a […]

First are my answers to the Make-To-Learn Contest: What did you make? I made a multi-function LED Array Program, like my previous one with Arduino UNO, but this time I made it with an ATmega32 microcontroller. I used regular C code to program it and no Arduino was involved at all. I also added a […]

UPDATE: I added an alarm function to both versions of the clock. UPDATE: I updated the code so that setting the clock does not affect the seconds accuracy – no resyncing of seconds required. UPDATE: I removed the personal messages from the clock code for the “Pusheen” version in the download links Video at:: http://youtu.be/ikNw1iLE9vg […]

Despite a low power consumption this relay handles 5A/250VAC while maintaining a considerably long lifetime. If we should mark an electronic component by a term “sympathic”, then the FTR-MY MY relay should be one of adepts …. Why? It´s simply chic. FTR-MY is: ● slim (5mm), so it doesn´t take much time on a PCB […]

Most people think of black holes as giant vacuum cleaners sucking in everything that gets too close. But the supermassive black holes at the centers of galaxies are more like cosmic engines, converting energy from infalling matter into intense radiation that can outshine the combined light from all surrounding stars

For scientists studying the impacts of space weather, one of the central mysteries of solar flares – the colossal release of magnetic energy in the Sun’s atmosphere that erupts with the force of millions of hydrogen bombs – is the means by which these explosions produce radiation and accelerate particles to nearly the speed of light within seconds.
