Observing distinctive geologic features on asteroid Toutatis
Posted on: 17 Nov 2015
(Phys.org)—Asteroid (4179) Toutatis, an Apollo-type near-Earth object (NEO) was thoroughly studied by Chinese Chang’e-2 spacecraft in 2012, when the space rock flew by Earth at a distance of 18 lunar distances. The probe, imaging the asteroid in high-resolution, has provided compelling information regarding Toutatis’ geological structure.
Atmega16/32 Development Board With LCD
Posted on: 17 Nov 2015
This instructable shows, how to do your own development board for Atmega16 or Atmega32 processors.The Internet is full of home made development boards, but I think that, there is room left for another one. This board have been very useful on my projects and I actually designed and made it to serve one of my […]
RGB Rotary Encoder with PWM and ISRs Using an ATmega328
Posted on: 15 Nov 2015
Description A long time ago I bought a couple RGB rotary encoders from Sparkfun because they were cheap and I was already spending a bunch on other stuff. I thought they would be neat for some interfaces since it includes a push button. The interrupt service routine (ISR) for pin changes on the rotary encoder (for […]
Fermi mission finds hints of gamma-ray cycle in an active galaxy
Posted on: 14 Nov 2015
Astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called “active” galaxy, whose emissions are powered by a supersized black hole. If confirmed, the discovery would mark the first years-long cyclic gamma-ray emission ever detected from any galaxy, which could provide new insights into physical processes near the black hole.

Guys, In previous weekend, I made myself a speaking ATMEGA128. I used ATMEGA128 and LM386 as an amplifier, Let’s get started Step 1: The part I need for this project These parts are needed for this project : 1. LM386 2.ATMEGA128 3.USBISP 4.AVRStudio 5. Small speaker 6. LCD 16×2 Step 2: Assemble the project Here’s […]
Team maps gas emissions from comet 67P/Churyumov-Gerasimenko
Posted on: 12 Nov 2015
The European Space Agency’s Rosetta spacecraft began orbiting comet 67P/Churyumov-Gerasimenko in August 2014, providing the closest and most detailed look at a comet to date. Now, a team led by astronomers at the University of Maryland has used data from Rosetta’s Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) cameras to generate maps of multiple gas emissions just above the comet’s surface.
Increased deforestation could substantially reduce Amazon basin rainfall
Posted on: 12 Nov 2015
Continued deforestation of the Amazon rainforest could diminish the amount of rain that falls in the Amazon River basin, finds a new study. These declines in rainfall could potentially alter the region’s climate, disrupting rainforest ecosystems and impacting local economies, according to the study’s authors.
Discovery of a new confinement state for plasma
Posted on: 11 Nov 2015
The National Institutes of Natural Sciences National Institute for Fusion Science applied the “Momentary Heating Propagation Method” to the DIII-D tokamak device operated for the United States Office of Science, Department of Energy, by the General Atomics and made the important discovery of a new plasma confinement state. This discovery was introduced in the November 4, 2015, issue of Scientific Reports, a journal of the British science journal Nature group, in an article titled “Self-regulated oscillation of transport and topology of magnetic islands in toroidal plasmas.”
Researchers discover a new phenomenon in materials science by observing the compaction of puffed…

There’s more to the snap, crackle and pop of Rice Krispies than meets the ear. A recent study by San Diego State University civil engineering professor Julio Valdes used the breakfast cereal to discover a new phenomenon in materials science: highly porous, brittle materials can deform in different ways depending on compaction velocity
I2C Bus for ATtiny and ATmega
Posted on: 11 Nov 2015
I love the Atmel AVR microcontrollers! Since building the Ghetto Development System described in this Instructable. I’ve had no end of fun experimenting with the AVR ATtiny2313 and the ATmega168 in particular. I even went so far as to write an Instructable on using switches as inputs, and extended the Ghetto Development System concept to […]
