Just stumbled across this thread, and seeing that I have an extra $0.02 in my pocket, here goes. The first step in any DAS (Data Acquisition System) design is to have a few specific use-cases in mind to limit the solution space. We don't want to guild the bikeshed! While Open Source software has a zero cost of replication, hardware most certainly does not! Any Open Source DAS should have a primary goal of making dirt-cheap hardware do wonderful things. If you are going to have an 8-sensor or 16-sensor system, using Ethernet for the sensor interconnection medium is silly. What is the cheapest interconnect medium for digital data? To minimize communication hardware costs, we should choose a protocol that is directly handled by dirt-cheap microcontrollers and a single power supply, which limits the choices to I2C, CAN, and TTL-level serial.
How do we get the data to a PC? An amazing number of sensors are available with I2C interfaces. What does our inexpensive DAS look like so far?

ZamiaCAD | Open source platform for advanced hardware design. Plasduino – open source data acquisition – Home. Plasduino is a data acquisition framework for the physics lab. It builds on top of an old, no longer maintained project for data acquisition through the parallel port (plas) and is based on the arduino platform (hence the name plasduino). If you are wondering what we are talking about, our overview paper is probably the single most useful reference, so take a look!
Plasduino is an open hardware/software project. The codebase is released under the GPL licence along with the shield schematics. Plasduino is written in python (relying on several third-party python modules) and uses PyQt4 for the graphical user interface. The plasduino code is hosted on bitbucket.

Neuroscientists Join the Open-Source Hardware Movement. Graduate students Josh Siegle and Jakob Voigts were planning an ambitious series of experiments at their MIT neuroscience labs in 2011 when they ran into a problem. They needed to record complex brain signals from mice, but they couldn’t afford the right equipment: The recording systems cost upward of US $60,000 each, and they wanted at least four.
So they decided to solve their dilemma by building their own gear on the cheap. And knowing that they wouldn’t be the last neuroscientists to encounter such a problem, they decided to give away their designs. Now their project, Open Ephys, is the hub of a nascent open-source hardware community for neural technology. Siegle and Voigts weren’t knowledgeable about either circuit design or coding, but they learned as they went along. Neuroscience has a history of hackers, Siegle says, with researchers cobbling together their own gear or customizing commercial systems to meet their particular needs. The OPEN MOTOR CONTROL: an open source motor controller for everyone. It is open source and based upon the ATmega32U4 microcontroller, and provided with drivers for two DC brush motors and a stepper motor. It receives commands via USB or serial ports, or via the I²C bus.
For those dealing with robotics, one of the problems to solve is the management of the motors used for the traction, that is to say: how to correctly power the motors needed in order to make your robot advance. If you work with Arduino, the first and immediate solution is to use a shield. Several of them can be found available for sale, from the simplest ones that allow to control separately the two small DC motors, to the most advanced ones that are able to measure the current drawn as well. Regardless of the manufacturer, the shields are all based on the usage of a power driver (usually the L298), that is directly interfaced to Arduino’s PWM outputs, and encircled by a few other components.

ADempiere VS iDempiere - iDempiere Open Source ERP. iDempiere is a fork or copy of ADempiere. Two of the core ADempiere architects decided they could better implement new technologies like OSGi, Buckminster and zk6 in new version of the code. Creating a fork meant they would have more control stewarding the code and directing the project. OSGI helps iDempiere structure the application and code base to better support the contributions of content experts. For example, let the WebUI people focus on and safely contribute in isolation from the accounting content experts. It also looks to provide a better way for companies to create and install modules for vertical market challenges. iDempiere freshens up the user interface with zk6.
iDempiere simplifies the ERP model. Special thanks goes to Trek Global for sponsoring much of iDempiere’s improvement. What is the best way to Learn iDempiere and ADempiere? I teach an on-line class that covers how to learn, configure and audit open source ERP. Why consider Open Source ERP? Anavi Technology - Open Source Hardware and Software for IoT. General Purpose Regulator | Projects | CircuitMaker. Introduction The General Purpose Regulator board is a power supply board designed specifically for projects that need a 5V supply up to 2 Amps for digital logic and microprocessors, along with +9V and -9V rails up to 500mA for powering analog circuits that require dual rail supplies, such as operational amplifiers (opamps). This is the perfect power supply for mixed signal products, for example digitally controlled audio electronics, radios, telecommunications and industrial electronics. Circuit Description Digital Supply The 5V digital power supply output is based on the well-known, low cost LM2596S "Simple Switcher" integrated DC-DC buck regulator from Texas Instruments.
The LM2596S is mature stable technology and easy to get at low cost. The LM2596S has a built in power transistor for switching the input voltage (via D3) to the main energy storage inductor (L1) and current rises linearly in L1, supplying the load and sharging the filter capacitor (C6) Analog Supply.

Introduction Relational database management systems are a key component of many web sites and applications. They provide a structured way to store, organize, and access information.
PostgreSQL, or Postgres, is a relational database management system that provides an implementation of the SQL querying language. It is a popular choice for many small and large projects and has the advantage of being standards-compliant and having many advanced features like reliable transactions and concurrency without read locks. In this guide, we will demonstrate how to install Postgres on an Ubuntu 14.04 VPS instance and go over some basic ways to use it. Installation Ubuntu's default repositories contain Postgres packages, so we can install them without a hassle using the apt packaging system.
Since we haven't updated our local apt repository lately, let's do that now. Sudo apt-get update sudo apt-get install postgresql postgresql-contrib Using PostgreSQL Roles and Databases sudo -i -u postgres psql \q \conninfo. Tutorial FreeCAD T2 (5 / 34): Haciendo prismas. FreeCAD/FreeCAD-addons: A convenient gathering of useful and well-developed FreeCAD plugins made by the community. A FreeCAD manual. FreeCAD is a free, open-source parametric 3D modeling application. It is made primarily to model real-world objects, ranging from the small electronic components up to buildings and civil engineering projects, with a strong focus on 3D-printable objects.
FreeCAD is free to download, use, distribute and modify, and its source code is open and published under the very permissive LGPL license. The data you produce with FreeCAD is fully yours, and can be recovered without FreeCAD. FreeCAD is also fundamentally a social project, as it is developed and maintained by a community of developers and users united by their passion for FreeCAD. This manual is an experiment at taking the opposite way from the official FreeCAD documentation wiki. This manual has been written for the current stable version of FreeCAD which is version 0.16.

Update (6/30/14): Added TI LP5907, reviewed noise figures. Update (2/1/14): Added the ADM7150/ADM7151 which is now at the top of the pack. Update (01/29/13): Revised the noise density numbers Update (8/27/12): Added the new TI TPS7A4700 regulator to the table. This device can source up to 1 A of current and ranks on top of the list. Also please ignore the noise density numbers, I need to revise them. The table below compares the noise level of some regulators used in current DIY modules vs a new breed of regulators that are used in portable consumer devices such as cell phones.
Just like phase noise in clocks, it is difficult to compare noise values among linear regulators because there is no common ground in specifying noise figures. The noise density numbers are taken off the noise density spectra charts in the data sheets (D) or when not available from the datasheet they are calculated (C) in accordance to the relationship presented in the video above.
