Omxplayer Omxplayer is a video player specifically made for the Raspberry Pi's GPU made by Edgar (gimli) Hucek from the XBMC/Kodi project. It relies on the OpenMAX hardware acceleration API, which is the Broadcom's VideoCore officially supported API for GPU video/audio processing. Raspberry Pi forum user spenning made precompiled binaries available on the forum.

Link to 1st Youtube video of the Easy StepperLink to 2nd Youtube video of the Easy Stepper The Idea The idea is to make a quick and simple tool to test stepper motors and mechanical assemblies such as stepper driven gearboxes and linear activators. The Motivation The reason for this project was my frustration over how much it takes to just test a simple stepper motor. The Controls The controls are really simple. When the potentiometer is centered the stepper motor will stand still. When the potentiometer is turned clockwise the stepper motor will start turning in one direction. The further you turn the potentiometer the faster the motor turns and when you turn the potentiometer back the stepper will slow down again. When you turn the potentiometer counterclockwise past the center the stepper motor will start turning in the other direction. The two buttons are for fast forward and fast backwards. Data Input: 8 to 24V AC/DC Size: 40X60mm PCB Outline Rev1
Home automation with RC wall plugs and Raspberry Pi [Jake] took some cheap hardware and figured out a way to use it as a huge home automation network. He’s chose a Raspberry Pi board to connect the radio controlled power outlets to his network. He wrote about his project in two parts, the first is hacking the RC outlet controller and the second is using the Raspberry Pi to manipulate it. These RC outlets are a pass-through for appliances that connect to mains (lamps, consumer electronics, christmas trees, etc). Some of the inspiration for this hack came from the whistle-controlled appliance hack.

The Elements of Computing Systems / Nisan & Schocken KIT IMPRIMANTE 3D PRUSA MENDEL i3 Kit complet imprimante 3D Prusa Mendel i3 - ERMES Edition. L'imprimante 3D Open source Prusa i3 est actuellement la dernière version des imprimantes 3D RepRap, conçue par le noyau de développeurs Prusajr. Cette troisième et dernière version est également une des plus distribuée dans le monde. Elle offre des résultats impressionnants avec un excellent rapport qualité / prix. Cette version est livrée avec un cadre rigide en aluminium et un châssis monté sur tiges filetées. Le lit chauffant et l'alimentation sont également fournis. L'extruder est de type J Head 3mm/0.5. L'électronique est gérée par une carte RAMPS 1.4. Les guidages sont exécutés par un système de douilles à billes et la motorisation est faite par l'intermédiaire de moteurs de type NEMA 17, de pignons et de courroies. Une fois montée, l'imprimante mesure environ 44x40x37cm et permet de réaliser des pièces allant jusqu'à 20x20x17cm. Elle se démonte et se range facilement dans sa mallette, ce qui permet de la transporter.
Electronic-Lab in a Box First question: What I really need everytime? soldering Iron and holder lab-power supply Multimeter, some wires and soldering tin cleaning sponge and flux fume-extractor (i don't have one but always wanted to build one) So I begin with the heavy thing, the power-supply put it in the middle and arranged everything around it in mind and constructed everything in sketchup. Since I don't move much around with that stuff and have a lot of wood waste I didn't bother weight. I will not give measurements here, because every part is fitted around what needs to be put inside the box and where it should be stored. Part list: 18mm glued hard wood plates for the upright plates (the only type that holds screws in grain direction properly!) Most parts should be found in a good sorted Hobby-room. I only used a few tools: cordless screwdriverdrills and the thing to sink screw heads (don't know the correct english name)a really good handsaw (I recommend to invest good money to one, it won't be wasted!)
Browse Anonymously with a DIY Raspberry Pi VPN/TOR Router Surf the Internet securely with your very own portable WiFi VPN/TOR router. You can configure a Raspberry Pi with Linux and some extra software to connect to a VPN server of your choice. The VPN connection encrypts your internet traffic so that hackers and spies can’t figure out what web sites you are visiting, and the web sites you are visiting can’t tell which computer you are surfing from. Not sure what board is right for you? Make:’s interactive Board Guide lets you dial into the field to find the best one for your needs. The router is small and portable, so you can plug it in anywhere, adding secure internet browsing to any occasion, from your room to the café. The project consists of a Raspberry Pi, two USB WiFi dongles, an SD card, and a power plug. If you don’t have Ethernet available, your router can connect to a WiFi network in addition to creating its own, acting as a bridge between your personal WiFi access point and an insecure WiFi.

From Sand to Processor or How a CPU is made - Intel It is hard to believe that a modern processor (CPU) is the most complex product in the world. What is so complex in this piece of metal? In this article I will try to explain how a modern processer (CPU) is made from the sand. Processor Manufacturing It takes about $ 5 billion dollars to build a processor manufacturing factory. The process of processor manufacturing looks like this: the special equipment is used to grow a mono-crystal of cylindrical shape from the molten silicon. Some Chemistry Lessons Let us take a closer look at the whole process of manufacturing. Originally, it is taken in the form of SiO2 sand, which is in arc furnaces (at the temperature about 1800 ° C) reduced by coke: SiO2 + 2C = Si + 2CO This silicon is called a "technical" and has a purity of 98-99.9%. 3SiCl4 + 2H2 + Si ↔ 4SiHCl3 These recycling reactions that are generated by side silicon-contained materials reduce the cost and eliminate the environmental problems: Photolithography Photo Resist Application Etching
