OLinuXino is completely open source hardware and open source software, which means you have access to all the CAD files and sources and you can reuse them for your own personal or commercial projects. OLIMEX Ltd has agreement with Allwinner for longevity support. OLinuXino design is improving continually, the other Linux boards have one or two revisions, our boards have many revisions (some of them 12 or more) as we listen to community feedback and implement new and new improvements, but keeping backward compatibility, so once you choose your OLINUXINO you can be sure you will get them always in same specs, just better and better with time. OLinuXino is available in any quantity. The project is hosted at Github The development discussion group OLinuXino forum
Magnetic core memory reborn Loading web-font TeX/Math/Italic Ben North, Oliver Nash [Also available as PDF] [Home] We outline the theory of magnetic core memory, and describe the design and fabrication of a core memory Arduino shield. 1 Introduction 1.1 What is magnetic core memory? Core memory is an old memory technology. Magnetic core memory was the most widely used form of digital computer memory from its birth in the early 1950s until the era of integrated-circuit memory began in the early 1970s. A core, a ring of magnetic material, stores one bit by the direction of its magnetisation. A magnetic core is a ring of ferrite material. It provides non-volatile storage. The core needs no power to retain its data. With many such cores, large memory modules were made, such as this example from a CDC machine of the mid-1960s. Cores were c.1mm across, and ran at c.1MHz. As the technology developed [1], the cores shrank from c.2mm diameter in the early 1950s to c.0.4mm by the early 1970s. 1.2 What is an Arduino? It worked.
Alternate reality game An alternate reality game (ARG) is an interactive networked narrative that uses the real world as a platform and employs transmedia storytelling to deliver a story that may be altered by players' ideas or actions. The form is defined by intense player involvement with a story that takes place in real time and evolves according to players' responses. Subsequently, it is shaped by characters that are actively controlled by the game's designers, as opposed to being controlled by artificial intelligence as in a computer or console video game. Players interact directly with characters in the game, solve plot-based challenges and puzzles, and collaborate as a community to analyze the story and coordinate real-life and online activities. ARGs generally use multimedia, such as telephones, email and mail but rely on the Internet as the central binding medium. Definition[edit] Unique terminology[edit] Among the terms essential to understand discussions about ARGs are: Computer/console/video games.
blog After two years, I think I have my Replicator (apparently the first one shipped) finally working reliably to produce >1 hour prints. Thank you @iandanforth for asking if I had a description of the mods I did and prompting me to write this. The Replicator has been a very frustrating product. After a few out-of-the-box failures, it worked great for the first week and then rapidly deteriorated. And a few months later, the Replicator 2 was announced and support for my product rapidly evaporated. Many of the things I print are small and take <15 minutes to print, so I’ve been dealing with a <30% success rate of printing, or using other 3d printers. The heated build platform and thermocouple issues were just bad original parts from Makerbot. Assuming the basic mechatronics of the printer work, the most critical fix is the new extruder design. The next most critical mod is replacing those stupid plastic cantilever arms with something sturdier.
Tellart | Experience Design & Engineering Novena A new open-hardware computing platform, flexible and powerful, designed for use as a desktop, laptop, or standalone board. Novena is a 1.2GHz, Freescale quad-core ARM architecture computer closely coupled with a Xilinx FPGA. It’s designed for users who care about Free Software and open source, and/or want to modify and extend their hardware: all the documentation for the PCBs is open and free to download, the entire OS is buildable from source, and it comes with a variety of features that facilitate rapid prototyping. Premiums & Pledge Levels We are offering four variations. All configurations will come with Debian (GNU/Linux) pre-installed, but of course you can build and install whatever distro you prefer! This is not a machine for the faint of heart. Stretch Goals After the campaign launched, we decided to offer four stretch goals. Case Design Features The first thing you’ll notice about the case design is that the screen opens “the wrong way”. “Just the Board” Spec Sheet Features: Mashable
Wandboard - Freescale i.MX6 ARM Cortex-A9 Opensource Community Development Board - BLOG Location based role play game Make a Laser Matrix Projector for the iPhone The Concept The idea is to add some kind of projector capability to a cell phone (e.g. iPhone) that isn’t too complex or expensive. Instead of using an expensive mini projector, I decided to use lasers instead to any bitmap font using a matrix of laser points, which is controlled by iPhone. The Hardware The hardware contains 3 basic parts: 5×7 laser matrix5 8-bit D-type latches (SN74LVTH573PW) to control the total 35 laser pointersMicrocontroller (PIC16F722) to control the decoder and manage the serial communication with iPhone – grab the code. The laser modules can emit 650nm red laser light, with power consumption of 2~5 mW. The Software The micro-controller software is fairly strait forward, it just waiting for command sent by iPhone via the serial port, and execute the command by controlling the 5 latches. Here’s what the application looks like on the iPhone. The iPhone side software is a bit more complex. The End Result: Video Demo:(I had some issues getting the keyboard to come up
