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.

Free Electronics Tutorials, from an Electronics Engineer Chapter 10: Computers and Electronics -- Build a simple 1 watt audio amplifier A simple 1 watt audio amplifier The solderless breadboard makes it easy to experiment with additions to the radio circuit. In this section, we will build a simple amplifier, so that a whole room can hear the radio through a speaker. Our amplifier will not be ear shattering, since we have made it as simple as we can to build, but the output is pretty impressive for a single transistor. Click on photo for a larger picture With the amplifier, our radio looks like the photo above. Below is a closeup of the amplifier section: We carry all the parts for the amplifier (except the battery) in our catalog. The amplifier needs these parts: An MPSW45A Darlington transistor This is the main working part of the amplifier. Using the labeled grid as before, the parts are connected this way: A more permanent version As before, we can copy the circuit onto a printed circuit board and solder all of the parts firmly in place. How does it do that? The heart of the amplifier is the transistor. Del.icio.us Google
Electronics 101 theory course FREE online basic - advanced 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.
