Global electronics community, element14, announced it has teamed up with CadSoft Computer GmbH and Microchip to present the EAGLE Design Competition – a four-month competition aimed to unite the most innovative design engineering communities using CadSoft EAGLE’s Version 6.

To enter the competition, applicants can register on the element14 community and post a screenshot of their project’s design layout, along with a written description of the build. Prizes will be awarded to the most creative idea, and include a Dell Alienware computer, a Microchip Eval kit, and a fully-loaded version of CadSoft EAGLE.

Additional contest details and judging criteria are available here

Kelvin informs us of an online stash of vintage engineering docs at tubebooks.org. He especially recommends you check out the technical books section/link.

Tubebooks is “a collection of vintage engineering texts, vacuum tube datasheets, and other obsolete information, presented free of charge and without annoying advertisements.”

SchemeIt | Free Online Schematic Drawing Tool | DigiKey – [via]

I just came across this: DigiKey is hosting a schematic editor as a web application, complete with PNG and PDF export, compiling a bill of materials, etc. It actually works better just running in the browser than some commercial schematic capture programs I’ve used. Now, if someone would just do this with printed circuit board layout…

PowerEsim- Free on-line switch mode power supply SMPS, circuit and transformer design, calculation, simulation software. More than 100 circuits and topologies are available with real constructed transformer.

It provides a virtual laboratory environment for users to wind and place every single turn of a transformer, and with the help of tens of thousands real modeled component on the market, user can simple pick and place the real component and stuff into the circuit, within a fraction of a second, our server will immediately return the result to the user. It is even faster than modifying prototype in real environment, and more than that is no worry of getting explosion of the prototype on real bench. It is Better than real.

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.
