Internet of Things Challenge: WIZ55io Modules Moved Fast

As soon as the WIZNet Connect the Magic 2014 Design Challenge launched on March 3, 2014, Internet of Things (IoT) innovators—from professional electrical engineers to creative electronics DIYers—around world began requesting free WIZnet WIZ550io Ethernet controller modules. And due to the popular demand for the modules, the supply of free units ran out on March 11.

Although free modules are no longer available, anyone with a WIZ550io Ethernet module, or W5500 chip, may participate in the competition.

Participants can purchase eligible parts at shopwiznet.com or shop.wiznet.eu.

NXP LPC800 Microcontroller Challenge

Attention microcontroller users around the world! Ready to enter NXP Semiconductor’s LPC800 Challenge? Getting started is straightforward.

Elektor and Circuit Cellar have partnered with NXP Semiconductors to promote the Challenge. Once you have your LPC800 mini-board and code, you simply register and start working. The rules and complete details are listed on the LPC800 Challenge webpage.

The entry deadline is August 30, 2013. Once all the entries are received, NXP will select the most unique, interesting and funny submissions to receive a LPC800 LPCXpresso development kit.

The LPC800 is an ARM Cortex-M0+-based, 32-bit microcontroller operating at CPU frequencies of up to 30 MHz. The LPC800 supports up to 16 KB of flash memory and 4 KB of SRAM. The peripheral complement of the LPC800 includes a CRC engine, one I2C-bus interface, three USARTs, two SPI interfaces, one multi-purpose, state-configurable timer, one comparator, function-configurable I/O ports through a switch matrix, and up to 18 general purpose I/O pins.

Electrostatic Cleaning Robot Project

How do you clean a clean-energy generating system? With a microcontroller (and a few other parts, of course). An excellent example is US designer Scott Potter’s award-winning, Renesas RL78 microcontroller-based Electrostatic Cleaning Robot system that cleans heliostats (i.e., solar-tracking mirrors) used in solar energy-harvesting systems. Renesas and Circuit Cellar magazine announced this week at DevCon 2012 in Garden Grove, CA, that Potter’s design won First Prize in the RL78 Green Energy Challenge.

The nearby image depicts two Electrostatic Cleaning Robots set up vertically in order to clean the two heliostats in a horizontal left-to-right (and vice versa) fashion.

The Electrostatic Cleaning Robot in place to clean

Potter’s design can quickly clean heliostats in Concentrating Solar Power (CSP) plants. The heliostats must be clean in order to maximize steam production, which generates power.

The robot cleaner prototype

Built around an RL78 microcontroller, the Electrostatic Cleaning Robot provides a reliable cleaning solution that’s powered entirely by photovoltaic cells. The robot traverses the surface of the mirror and uses a high-voltage AC electric field to sweep away dust and debris.

Parts and circuitry inside the robot cleaner

Object oriented C++ software, developed with the IAR Embedded Workbench and the RL78 Demonstration Kit, controls the device.

IAR Embedded Workbench IDE

The RL78 microcontroller uses the following for system control:

• 20 Digital I/Os used as system control lines

• 1 ADC monitors solar cell voltage

• 1 Interval timer provides controller time tick

• Timer array unit: 4 timers capture the width of sensor pulses

• Watchdog timer for system reliability

• Low voltage detection for reliable operation in intermittent solar conditions

• RTC used in diagnostic logs

• 1 UART used for diagnostics

• Flash memory for storing diagnostic logs

The complete project (description, schematics, diagrams, and code) is now available on the Challenge website.

 

Renesas RL78-Based Design Project Opportunities

Did you miss the 1:00 PM EST deadline for the Renesas RL78 Green Energy Challenge? Do you have an unfinished project? No worries! You can still make something of your RL78-related project and the work you’ve put into it! Circuit Cellar and Elektor have several exciting non-contest-related opportunities you’ll find interesting and advantageous!

The Circuit Cellar/Elektor staff wants to know about your work. Even if your project is unfinished, let the staff know what you’re working on and the project’s status. Upload your project or email us your information.

If the staff is interested in your work, an editor will consider approaching you about one or all of the following non-contest-related opportunities:

  • Distinctive Excellence: If the editorial team thinks your project has merit, you might be eligible for “Distinctive Excellence” designation. After past design challenges, Distinctive Excellence recipients added the honor to their resumes, wrote articles about their projects, and gained notoriety in the design community.
  • Print Magazine Opportunities: The editorial team might think your project is worthy of being published in Circuit Cellar or Elektor magazine. Design Challenges and the print magazine are completely separate. If you are offered an opportunity to write an article and it is published, you will paid a standard author honorarium.
  • CircuitCellar.com Opportunities: The Circuit Cellar editorial team will review your submission and consider posting it on CircuitCellar.com to show the world the effort and progress you’ve made. You can post your project info on the site in the spirit of sharing and the furtherance of engineering innovation! Who knows? Readers might provide you with valuable feedback about your unfinished project. Or perhaps you’ll inspire another person to build something of their own! Perhaps your project will catch the eye company looking to learn more about you work!
  • Interview Possibilities: The editorial team might find your approach to design interesting and consider interviewing you for an upcoming issue.
  • Future Design Collaboration: The Elektor Lab builds and tests innovative electronics projects. If your project—whether finished or in progress—interests an Elektor Lab engineer or editor, someone might contact you to discuss development, testing, or even production opportunities.

As you can see, you have some excellent reasons to contact the Circuit Cellar/Elektor staff.

To submit a finished project, an abstract, or simply info about our work, you can still use the Challenge Entry Form. Or, you can simply ZIP your files and email them to the Circuit Cellar Editorial Department. (Write “RL78 Project” and your project’s name or registration number in the email’s subject line.)
