This is a website down alarm using a Tessel module. Check it on projects.tessel.io:

If your website goes down, you want to be the first to know. Make it obvious when there’s a problem by hooking up a big alarm light to a Tessel, which will ping your website every few seconds to check for trouble.

Continuously off: all is well
Continuously on: website being monitored is down
Two-second bursts (on or off): system error; monitoring isn’t working (reset the Tessel)

The NXP Flyback SMPS Design Tool helps you design flyback power supplies using NXPs TEA1721, TEA1723, TEA1733 and TEA1738 family. The TEA1721(A, B, D, F) family, the TEA1723(A, B, D, F) family, the TEA1733(A, B, C, M, L) family and TEA1738(F, G, L) family are low cost Switched Mode Power Supply (SMPS) controller IC’s intended for flyback topologies.

The latest update of the tool combines the TEA172x family and the TEA173x family into one tool. It comes along with a new style and an improved flow. Now it is also possible to export all design parameters, results and graphs automatically into an Excel sheet for post-processing or presentation purposes. Furthermore the database of transformer cores is extended.

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.
