ecDB – [via]

ecDB is basically a place where you, as an electronics hobbyist (or professional) can add your own components to your personal database to keep track of what components you own, where they are, how many you own and so on.

ecDB is created by Nils Fredriksson and designed by Buildlog.

Me, Nils, have always wanted to have a system like this to keep track of what component I own. Before I created this system I (I guess you too…) had to dig through boxes filled with components to maybe find that component I needed. This is an unnecessary task to do, it not only takes time, and it also can be really frustrating not to find that component you are looking for. So I ended up creating this website where I easily can keep track of my components!

We are happy to announce the release of CircuitLab, a browser-based schematic editor and circuit simulator.

With CircuitLab you can sketch your circuits as easily as you would on a piece of paper, and then simulate your circuit right in your browser to see how it would work in real life! You can then tweak, design, and iterate — all in one tool, all in your web browser.

CircuitLab has powerful SPICE-like device models, and the simulation engine supports mixed-mode analog and digital components side-by-side, so you can rapidly test your ideas for a wide range of possible projects. In addition to DC calculations and time-domain simulation, CircuitLab also has many advanced simulation capabilities, including frequency-domain (small signal) analysis, stepping through circuit parameters, and arbitrary Laplace transform function blocks.

CircuitLab is completely web-based, which not only means itʼs cross-platform (Windows/Mac/Linux) and requires no installation or plug-ins, but also means that all you the circuits you choose to make public can be shared by just copy & pasting a URL!

Instead of the usual forum posts with static screenshots from different desktop tools, the online electronics community can use CircuitLab to share useful URLs (as well as PNGs and PDFs) which link directly to interactive, editable, runnable schematics. In just a few clicks, another hobbyist can open that circuit, make a change, simulate it, and post the new version back to the community.

CircuitLab is now available publicly at https://www.circuitlab.com. Make sure you check out the Quick-Start Circuits for some great examples of what CircuitLab can do!

MITx 6.002 – [via]

6.002x (Circuits and Electronics) is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. At MIT, 6.002 is in the core of department subjects required for all undergraduates in EECS.

The course introduces engineering in the context of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first- and second-order networks; design in the time and frequency domains; and analog and digital circuits and applications. Design and lab exercises are also significant components of the course. You should expect to spend approximately 10 hours per week on the course.

Online MSP430 Editor and Compiler – [via]

This is an online MSP430 firmware editor. This means that you edit C-code within your web browser without having to install an IDE such as IAR or CCS on your computer. The files are compiled on our server and you download them from there. Using this tool to develop MSP430 firmware from within your browser is very simple, but does not offer as many advanced features as an expensive IDE.

Arena PartsList  is a BOM manager that’s integrated with the Octopart component database. It has neat functions like auto-fill, that automatically adds a part to your database directly from a sales page of a electronics component distributor like Farnell, Digi-Key, Mouser, etc… [via]

Octopart just tweeted a free tool for BOM management. You can import a CSV file into a project and auto fill details using Octopart.

Their main tool is a more comprehensive product with collaboration features and stuff. They charge $79 per user per month, which includes training, tech support, upgrades, etc.

In February you can win a digital multimeter in value of € 200

In autumn 2011 the SOS electronic launched to its customers and fans a unique new newsletter, which is tailor-made. You can choose what you want to read and how often you’ll get!

The newsletter contains product articles on a high professional level and the main task is primarily to inform developers about new trends and components in the industry. For these articles especially for this purpose is assigned a specialist who has worked as a developer itself, so he can feel the need to develop hardware applications.

Newsletter uniqueness lies in the fact that you can set up yourself in your profile an area of messaging and the frequency of such transfers.

Actually the newsletter is sent to more than 40 000 email addresses. If you are not among them, you can subscribe for it. In 2012, you have two more reasons to do it so.

If you do it, you can win one of the monthly prices. Of all those who subscribe for newsletter in the particular month will be choose by a lot a winner of valuable price.

In addition, those who subscribe in during the year 2012 and stay subscribed for the newsletter for the whole time will be listed for a drawing of a professional soldering station Weller WX 2!

So remember:

1. You can subscribe for SOS newsletter at http://www.soselectronic.com/newsletter

2. In February 2012 we will be drawing the winner of intelligent digital multimeter UNI-T UT71E in value of 200 €.

3. Throughout the year 2012 you can compete for professional soldering station Weller WX 2021 in value of 1100 €.

element14, Microchip and Matrix introduce the new PIC18 Flowcode Developers Kit.  Lowers the barrier to electronics design with easy to use Graphical Programming 

30 January 2012 – London, element14, the first collaborative global electronics community from Premier Farnell plc (LSE:pfl), has teamed up with Microchip and Matrix to introduce the new PIC18 Flowcode Developers Kit.  This innovative development and demonstration kit is designed to offer a hands-on, easy approach to electronics design using Flowcode, one of the world’s most advanced graphical programming languages for microcontrollers.

The development platform is based on a Microchip PIC18F26J50 low power, 8-bit PIC18F26J50 microcontroller, and is integrated with temperature sensor, capacitor touch sensor and potentiometer to help developers verify programs designed using Flowcode.

“The new PIC18 Flowcode Developers Kit is an innovative, fully featured yet low cost solution designed to help developers realize their designs in working hardware,” says Mike Powell, Technology Development Manager, Premier Farnell.  “Optimized for Flowcode development, the board has several expansion options, it can be used as a black box and is mounted with a PIC 18 device that is low power, but high performance.

The competitive advantage of Flowcode is that it allows those with little-to-no programming experience to create electronic systems in minutes. Flowcode supports code generation for the PIC® (PIC12, PIC16, and PIC18 series ), PIC24 and dsPIC® series of microcontrollers. The professional edition includes drivers for a range of sub-systems including LCDs, keypads, seven-segment displays, ADC and PWM, as well as communication protocols including I2C, SPI, RS-232RS-232, Zigbee and TCP/IP, among others.

Flowcode is compatible with Microchip’s PICkit programmer as well as third party programmers. It is also compatible with the HI-TECH C compiler. A ‘Lite’ version of Flowcode 4 is included in the kit.
