Touch 8 - Custom Control Module based on a ATMEL AVR Microcontroller - Hacked Gadgets - DIY Tech Blog Alberto Ricci Bitti has developed a cool touch controller called the Touch 8. I can see this programmable controller having the ability to replace lots of single purpose controls that are used to control equipment. "Touch8 is a module that integrates a 3" LCD touch-screen and a RISC processor. The processor includes a powerful library to handle graphics and windows. The module also includes a DC power supply and RS485, CAN 2.0B and TTL-serial interfaces to connect to every kind of machinery. There are also I/O pins including SPI and I2C. Scientists Explain Why Computers Crash But We Don’t The hierarchical organization of the transcriptional regulatory network ofbacterium E. Coli, left, shows a pyramidal structure compared to the Linuxcall graph, which has many more routines controlling few generic functions at the bottom. Nature and software engineers face similar design challenges in creating control systems. The different solutions they employ help explain why living organisms tend to malfunction less than computers, a Yale study has found. The Yale team compared the evolution of organisms and computer operating systems by analyzing the control networks in both a bacterium Escherichia coli and the Linux operating system. “It is a commonplace metaphor that the genome is the operating system of a living organism. Both E coli and the Linux networks are arranged in hierarchies, but with some notable differences in how they achieve operational efficiencies. Operating systems are like urban streets – engineers tend to focus on areas that get a lot of traffic,” said Gerstein.

Operating system For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers. Types of operating systems Single- and multi-tasking Single- and multi-user Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem.[6] A multi-user operating system extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, and the system permits multiple users to interact with the system at the same time.

Free Electronics Tutorials, from an Electronics Engineer Where to Find Information About Metals and Alloys March 31, 2011 AT 10:03 am As I’ve gotten more and more into machining, I’ve found that I often require information about metals and alloys. I’ve collected a few resources which I’ve found helpful, and which I’d like to share with you. There are several places where you can find decent metal information — by “information”, I don’t just mean density or history of human use — I’m referring to information about working with a metal, such as machinability, weldability, heat treatment, and so forth. The standard reference for most alloys used in manufacturing is the Metals Handbook, published by ASM International (formerly the American Society for Metals). ASM also offers subject guides on their website, which are free. The second resource I’d recommend is Machinery’s Handbook. The third (and most obvious) resource is A Personal Appeal from Jimmy Wales Wikipedia. Metal suppliers can be a good resource as well. Hopefully you’ll find these resources helpful in your quest for metal data. Related

problems wiht avr32-linux-gcc Because some developers here on avrfreaks compile most of the AVR32 toolchain from scratch (myself included), we don't often use the packages (except to install closed-source software such as avr32program and associated libraries). Apparently the current avr32-gnu toolchain distributed by Atmel via the package repository is for standalone development without embedded Linux. The debian packages install a compiler that is intended for running standalone (i.e. non-Linux) programs on AVR32 architecture. Then you need to run buildroot so that it compiles the Linux toolchain, which is avr32-linux-gcc. www.atmel.com/dyn/resources/prod_documents/doc32062.pdf The binaries for the toolchain, when compiled, should be in the directory /build_avr32/staging_dir/bin In this directory, you will find avr32-linux-gcc.
Hack Attack : How to Create aXXo Quality DVD Rips | DailyApps DVD movies are the best way to pass time while you are at home and have nothing else to do. There are times though when the DVD you rented at the local DVD store has to be returned within 24 hours and you want to watch the movie again and again. In such situations ripping the DVD’s is the best way to go. If you have been a P2P torrents user for any length of time, I’m sure you’ve heard of aXXo. photo credit: ryoichitanaka’s Sometime in the past aXXo had stopped releasing new movies, and many users were angry. Its as simple as going to a DVD rental store or site, getting the DVD and creating a perfect 700mb DVD rip for the rest of us to enjoy. Without further delay, lets get started with the process, of creating your super small high quality DVD Rip. Install the above softwares, just like you would install any other software, and then grab yourself a cup of caffeine before you proceed. PART 1 : Ripping the DVD to your Hard Disk Step 1 Fire up DVD Decrypter. Step 2 Step 3 Open up Auto GK.
Circuit Symbols Tutorial - Electronics Circuit Symbols General Theory Tutorials & Circuits - Hobby Projects The diagram below shows passive components, resistors, capacitors and inductors, and also electrical components such as switches, relays, motors and lamps. Also shown are the symbols for wires that are not joined (no physical electrical connection) and wires that are joined (a physical electrical connection). This next diagram depicts active components, the difference between active and passive is that active components require a power source to work, whereas passive components do not. The top symbols represent vacuum tube or thermionic devices. Although at one time, these were being replaced by the smaller transistor and integrated circuits, they are finding their way back into electronics for use in professional audio equipment and some radio receivers.
