contest

PyroElectro.com proudly presents their new contest:

View the Pyro Propeller Clock POV Project to learn more about the concept Persistence of Vision (POV) – a phenomenon where an afterimage persists for roughly one twenty-fifth of a second on the retina after the stimulus that produced it is removed.

Build an original electronic device demonstrating POV and photograph in action in a darkened environment. You may use any electronic parts desired as long as the POV signals are driven by either an FPGA or CPLD.

Submit your entry to contests@pyroelectro.com with the subject line “PyroElectro POV Contest.” Your entry must contain two photos of the device – one of its components in a well-lit environment and one of it in action in a darkened environment – as well as a circuit diagram and the VHDL code to run the device.

edasolver

Imagine specifying the types of components needed for an electronics project and letting an algorithm take care of the component selection and pin matching. Well, eda_solver makes this idea a reality.

I just launched a site called edasolver.com where users translate their project requirements into a JSON format and let the algorithm take care of finding components and pin connections that support each other. For example, it can be used to find the cheapest Arduino model that supports 10 servo motors and match the pins in such a way that the I2C ports are still preserved. It can be thought of a project requirements to schematic generator.

by Michael Dunn:

Thanks to software engineer and hardware hobbyist Bob Alexander, next time you need a batch of PCBs, make his PCB Shopper site your first stop. Enter your basic board specs, like size, layer count, and quantity, and out pops a list of vendors (from China, USA, Canada, & Germany) along with prices and delivery time (BTW, here’s another Canadian source that hasn’t made his list yet: Bittele/7pcb). The site also has a nice little summary of CAD tools.

There is cool contest for EEs, with actual prizes running right now.  EEWeb.com is running the “2014 European Design Freedom Contest”  (at http://www.eeweb.com/freedomcontest) and the prizes include iPads and iPods as well as a football table, espresso machine, or bike.  You’ll get to design projects using the Freescale Freedom Kinetis ARM based development platform.

The contest uses free online tools from Digi-Key.  The first part of the contest uses Scheme-It for you to generate a block diagram of your contest entry that uses one of the 10 available Freescale Freedom Platforms; the project can be a solution to a real problem or something novel.  This first phase of the contest runs through the end of June.

In the second phase, create a PCB design of your project.  You can also go with a software submission using ARM mbed studio online software (mbed.org).  The 2nd phase runs through Oct 10th.

EveryCircuit helps electronics enthusiasts to quickly prototype circuits and share their designs. Students find it useful because of real-time interactive simulation and visualization of circuit operation. EC was first released as an Android app (over 1M users). Thanks to Google’s new Portable Native Client technology that lets us run C++ code at full speed in Chrome browser, it is now available online.

EveryCircuit is a web and mobile app for EE students and circuit enthusiasts. Its interactive visual circuit simulation is great for understanding how circuits work and for quick prototyping of design ideas. And it has a huge online repository of educational and practical circuits designed by EveryCircuit community.

With Texas Instruments’ WEBENCH Schematic Editor, engineers can customize power-management designs and simulate the circuit created within the WEBENCH environment. According to the company, the new feature reduces design and verification time from hours to minutes. The editing and simulation package maintains a library of over 40,000 components. As a result, it’s possible to incorporate multiple mixed output capacitors, filtering, board parasitics, and snubber circuits into WEBENCH power-supply designs. Then those customized power designs can be simulated (using the WEBENCH Power Designer’s Spice simulator) before they’re exported to CAD development platforms like Cadence OrCAD Capture CIS, Mentor Graphics Xpedition xDX Designer, CADSoft EAGLE, and Altium formats (e.g., Altium Designer). The WEBENCH environment consists of online tools such as Designer and Architect that enable end-to-end analog circuit design.

3DRAG_hacking_bianca-500x375

There is a new contest over open-electronics.org for people who bought the 3Drag or K82003 printer. Just show the OSHW community what you can do with your printer and get ready to win great gifts. The competition is intended to reward both people more gifted in technical/design, and those with artistic talent who, with their experience, are able to obtain from the files available on the Internet, objects that are perfect from an architectural, design or creativity point of view.

Thus here is this 3Drag Competition, reserved for those who possess a 3Drag or a Velleman K8200 3D printer (based on the same design).
Nowadays it’s plenty of this machines: in fact, thanks to the collaboration with Velleman, the 3Drag (recoded as K8200) had a widespread distribution throughout the world, spreading among students, hobbyists, new artisans, creating new skills and new job opportunities.
