I recently came across this neat web app that let’s you draw an equation and have it automatically converted to LaTeX or MathML. You can also submit the eq. to Wolfram Alpha for evaluation. This is actually a demo page for MyScript handwriting recognition software, and it recognizes all the standard LaTeX symbols, including Greek letters and set operators. Super handy if you want to draft up a quick LaTeX expression and can’t remember the special character codes.

Joint partnership builds on MITx and Harvard distance learning; aims to benefit campus-based education and beyond. EdX is a not-for-profit joint venture between Harvard University and the Massachusetts Institute of Technology to offer online versions of their classes and those of other universities. At the same time, edX will support Harvard and MIT faculty in conducting research on teaching and learning on campus through tools that enrich classroom and laboratory experiences. The goal of this initiative is to create a global community of online learners while improving education for everyone. To learn more about edX, visit http://www.edxonline.org.

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

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.
