Ready for the Pi-Face Digital? What’s that? you ask.

Pi Interface Digital, or Pi-Face Digital, is a Raspberry Pi accessory board Premier Farnell will begin distributing in early 2013. You can plug it into a Raspberry Pi and start designing immediately. Plus, you can connect sensors to Pi-Face Digital for a variety of purposes, such as temperature- or pressure-monitoring applications.
Pi-Face Digital is the first of a range of interfaces to allow the Raspberry Pi to control and manipulate the real world. It allows the Raspberry Pi to read switches connected to it – a door sensor or pressure pad perhaps, a microswitch or reed switch, or a hand held button. With appropriate easy to write code, the Raspberry Pi then drives outputs, powering motors, actuator, LEDs, light bulbs or anything you can imagine to respond to the inputs… The hardware provides an easy and consistent programming interface, in Scratch (as shown running on a Raspberry Pi in the photograph) and Python with good observability to promote easy development, and reduce technology barriers.
Did you know Circuit Cellar’s parent company, Elektor, offers a standard PCB service? The PCB service was originally launched in 2009, and since then more than 3,000 users have been registered.
Who will benefit from the service? Ask yourself: Are you an electronics designer who occasionally designs a PCB and then sends it off to a PCB manufacturing house? If so, you’re likely familiar with that nagging feeling of uncertainty about the correctness of your production files. Did you check the Gerber files you uploaded? Are you sure that the PCB manufacturing house will interpret your board data properly?
The PCB Visualizer and Checker is a fully automated interactive web tool that enables you to review your design files before ordering the PCB. After uploading your design files, the tool analyzes them and shows you what the manufacturer sees. Possible design issues are highlighted and you’re provided insight into critical areas of the PCB production process. Your design is verified against your board specifications, and you’re provided a list of the modifications needed to get it ready for production. Finally, the visualizer renders the board as it will be shipped before production has even started!
Want to learn more about Embedded Linux? You’re in luck. On Wednesday, November 14, Elektor and Farnell/element14 will partner to run an informative webinar on the topic at Electronica 2012 in Munich, Germany. If you’re at the show, you can attend the recordings for free. Register before October 31 to get free Electronica entry tickets from Farnell/element14.
Attendees should go to the Farnell/element14 stand (Hall 5, Stand 558) for the Elektor Academy seminar, which will focus on the latest developments on the innovative Embedded Linux board. You can watch the presentation and ask the experts questions. The webinar will be recorded and webcast a bit later.
Presenter: Embedded Linux expert Benedict Sauter, the board’s designer
Description: Benedict Sauter will take you through the design and update us on the latest applications.
When: Wed, November 14, 2012
Time: 11:30 CET
Where: Farnell element14 stand (Messe München, Hall 5, Booth 558)
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 yourunfinished 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.)
Domotics (home automation) control systems are among the most innovative and rewarding design projects creative electrical engineers can undertake. Let’s take a look at an innovative Beagle Board-based control system that enables a user to control lights with a 10.1˝ capacitive touchscreen.
• An I/O board for testing purposes
• An LED strip board for controlling an RGB LED strip
• A relay board for switching 230-VAC devices
• An energy meter for measuring on/off (and also for logging)
ELektor editor and engineer Clemens Valens recently interviewed Koen van Dongen about the design. Van Dongen describes the system’s electronics and then demonstrates how to use the touchscreen to control a light and LED strip.
As Valens explains suggests, it would be a worthwhile endeavor to incorporate a Wi-Fi connection to enable cellphone and tablet control. If you build such system, be sure to share it with our staff. Good luck!
