BoardSerialSingleSided3 If you don't have an easy way to order an Arduino board or kit, you can etch this PCB design by hand and solder it together. It is pin-compatible with the Arduino Diecimila, and should work with any Arduino shield. This is the third revision of the board: the Arduino Single-Sided Serial version 3, or s3v3, or Arduino Severino. It was designed by Adilson Akashi, based on the previous version.

Amarino - "Android meets Arduino" - Home Physics Simulation with Java Diaspora Diaspora is the privacy aware, personally controlled, do-it-all, open source social network. On November 23, 2010 was announced that Diaspora is in private alpha phase. Since August 27, 2012 Diaspora is ruled by the community (announcement). Prerequisites Since Diaspora can run on MySQL and PostgreSQL you need to decide which one you want to use. Install one of them and set it up. Installation Obtain the diaspora package from the AUR and build and install your desired database support with makepkg -si --pkg diaspora-mysql or makepkg -si --pkg diaspora-postgresql. Now edit /etc/webapps/diaspora/database.yml and fill out the needed values. Ensure your database is running and then switch to the diaspora user: $ su diaspora $ cd Create the database and initialize the schema: bin/bundle exec rake db:create db:schema:load If the user you specified in the database.yml file can't create databases leave the 'db:create' out and create a database named diaspora_production by hand.

Freeduino Francois Junod Francois Junod I can hear you asking "What is an Automate and who is Francois Junod?" An automate is a combination of art, sculpture, and mechanics used to create articulated, moving models resembling life and fantasy in all its forms. I first met Francois a few years ago when my friend Stewart Lesemann took a job with Vianney Halter in St. And so, over the past few years I’ve quietly slipped into the wonderland of the Junod ateliers trying to record the ever-changing landscape that has captured my imagination. Many of the images below can be clicked to view larger versions. Francois and Sabine doing a bit of brain surgery One of my favorites, in two modes. The Birds... Crash landing Some of Francois’ tower clock movements. Proceed to Part 2
The diaspora* Project Tutorials New! Getting Started with LTspice LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with an impressive library of passive devices. Over 1000 models are included in the download but you can also add third party models. RFID Basics An overview of Radio Frequency Identification (RFID) technology. LIS3DH Hookup Guide A guide to connecting the LIS3DH to a microcontroller and using the Arduino library. Lessons in Algorithms Learn techniques on how to use Finite Impulse Response (FIR) filters and other data-processing tools to turn data into information. Illuminated Mask Use LilyPad LEDs, a switched battery holder, and coin cell battery to make a fun light up mask for your next costume party. Glowing Pin Create a quick and easy piece of e-textile art using a LilyPad LED, battery holder, conductive thread, and coin cell battery. Light-Up Plush Craft a light-up plush with LilyPad LEDs controlled by pressing a button and sliding a switch in the creature's hands.
OpenH264 Arduino Astronomical Clock for Automatic Light Control Arduino Astronomical Clock for Automatic Light Control There are many ways to automatically control these lights. The gadget I was using (until I completed this project, that is) was a simple mechanical timer. This product allows you to set separate turn-on and turn-off times and those repeat every day. Figure 1 - Sunset time variation at my location (note: time axis is "DST time" a.k.a "summer time") Another approach to this problem, and one that you often find in many beginner elecronics projects, is to turn the lights ON/OFF based on some photo-sensitive device; a LDR or a photo-transistor for example. My objective with this project was to build a system that, given my latitude and longitude coordinates and the current time/day of the year, automatically calculates the sunrise and sunset times, controlling the lights accordingly. So here are the features/objectives for this project: - Automatic sunrise and sunset relay control to turn lights (or some other AC load) on/off respectively
Software | OpenDaylight OpenDaylight “Helium” -- The Rise of Open SDN OpenDaylight is an open platform for network programmability to enable SDN and NFV for networks at any size and scale. The community’s second release “Helium” comes with a new user interface and a much simpler and customizable installation process thanks to the use of the Apache Karaf container. For those looking to manage their networks using OpenDaylight, there is deeper integration with OpenStack, including significant improvements in the Open vSwitch Database Integration project, and a technology preview of advanced OpenStack features such as Security Groups, Distributed Virtual Router and Load Balancing-as-a-Service. OpenDaylight software is a combination of components including a fully pluggable controller, interfaces, protocol plug-ins and applications. With this common platform both customers and vendors can innovate and collaborate in order to commercialize SDN- and NFV-based solutions. Download Helium
