Q&A with Arduino-Based Skube Codesigner

The Arduino-based Skube

The Arduino-based Skube

Andrew Spitz is a Copenhagen, Denmark-based sound designer, interaction designer, and programmer. Among his various innovative projects is the Arduino-based Skube music player, which is an innovative design that enables users to find and share music.

Spitz worked on the design with Andrew Nip, Ruben van der Vleuten, and Malthe Borch. Check out the video to see the Skube in action. On his blog SoundPlusDesign.com, Spitz writes: “It is a fully working prototype through the combination of using ArduinoMax/MSP and an XBee wireless network. We access the Last.fm API to populate the Skube with tracks and scrobble, and using their algorithms to find similar music when in Discover mode.”

The following is an abridged  version of an interview that appears in the December 2012 issue of audioXpress magazine, a sister publication of Circuit Cellar magazine..

SHANNON BECKER: Tell us a little about your background and where you live.

Andrew Spitz: I’m half French, half South African. I grew up in France, but my parents are South African so when I was 17, I moved to South Africa. Last year, I decided to go back to school, and I’m now based in Copenhagen, Denmark where I’m earning a master’s degree at the Copenhagen Institute of Interaction Design (CID).

SHANNON: How did you become interested in sound design? Tell us about some of your initial projects.

Andrew: From the age of 16, I was a skydiving cameraman and I was obsessed with filming. So when it was time to do my undergraduate work, I decided to study film. I went to film school thinking that I would be doing cinematography, but I’m color blind and it turned out to be a bigger problem than I had hoped. At the same time, we had a lecturer in sound design named Jahn Beukes who was incredibly inspiring, and I discovered a passion for sound that has stayed with me.

Shannon: What do your interaction design studies at CIID entail? What do you plan to do with the additional education?

Andrew: CIID is focused on a user-centered approach to design, which involves finding intuitive solutions for products, software, and services using mostly technology as our medium. What this means in reality is that we spend a lot of time playing, hacking, prototyping, and basically building interactive things and experiences of some sort.

I’ve really committed to the shift from sound design to interaction design and it’s now my main focus. That said, I feel like I look at design from the lens of a sound designer as this is my background and what has formed me. Many designers around me are very visual, and I feel like my background gives me not only a different approach to the work but also enables me to see opportunities using sound as the catalyst for interactive experiences. Lots of my recent projects have been set in the intersection among technology, sound, and people.

SHANNON: You have worked as a sound effects recordist and editor, location recordist and sound designer for commercials, feature films, and documentaries. Tell us about some of these experiences?

ANDREW: I love all aspects of sound for different reasons. Because I do a lot of things and don’t focus on one, I end up having more of a general set of skills than going deep with one—this fits my personality very well. By doing different jobs within sound, I was able to have lots of different experiences, which I loved! nLocation recording enabled me to see really interesting things—from blowing up armored vehicles with rocket-propelled grenades (RPGs) to interviewing famous artists and presidents. And, documentaries enabled me to travel to amazing places such as Rwanda, Liberia, Mexico, and Nigeria. As a sound effects recordist on Jock of the Bushvelt, a 3-D animation, I recorded animals such as lions, baboons, and leopards in the South African bush. With Bakgat 2, I spent my time recording and editing rugby sounds to create a sound effects library. This time in my life has been a huge highlight, but I couldn’t see myself doing this forever. I love technology and design, which is why I made the move...

SHANNON: Where did the idea for Skube originate?

Andrew: Skube came out of the Tangible User Interface (TUI) class at CIID where we were tasked to rethink audio in the home context. So understanding how and where people share music was the jumping-off point for creating Skube.

We realized that as we move more toward a digital and online music listening experience, current portable music players are not adapted for this environment. Sharing mSkube Videousic in communal spaces is neither convenient nor easy, especially when we all have such different taste in music.

The result of our exploration was Skube. It is a music player that enables you to discover and share music and facilitates the decision process of picking tracks when in a communal setting.

A Low-Cost Connection to the IoT

In Circuit Cellar’s March issue, columnist Jeff Bachiochi tests the services of a company he says is “poised to make a big impact” on the Internet of Things (IoT).

This shows the I2C interface Bachiochi designed to enable available clamp-on current sensors to be monitored. He added four of these circuits to a PCB, which includes the circuitry for an imp card.

This shows the I2C interface Bachiochi designed to enable available clamp-on current sensors to be monitored. He added four of these circuits to a PCB, which includes the circuitry for an imp card.

Established in 2011, Electric Imp offers a flexible connectivity platform meant to enable any device to be connected to the IoT. The platform, called the “imp,” provides an SD-card sized module (including an 802.11b/g/n Wi-Fi radio package) that can be installed on any electronic device to go online. A powerful processor runs the imp OS.

“You only need to supply an SD card socket (and a few other components) to your product to give it connectivity,” Bachiochi says. “The imp’s processor has the power to run your entire product if you wish, or it can be connected via one of the supported serial protocols. The imp OS provides secure connectivity to the imp cloud. The imp cloud keeps your imp updated with the latest firmware, features online development tools, and provides cloud-side services for every imp in the field.”

“As with many cloud service organizations, development is generally free,” Bachiochi adds. “Once you’ve committed and have product rollout, the service will charge for its use. This could be a flat fee, a per-connection or data throughput fee, or a combination of fees. Basically you (or your customer) will have to pay to have access to the information, which pays for the support framework that keeps it all working.”

In his article, Bachiochi dives into a straightforward data-collection project to demonstrate how to use the imp in a product. The goal of his application was to log the activity of 220-V water pump and twin water softeners.  The project is the launching point for his comprehensive and detailed look at the imp’s hardware, software, and costs.

“It’s easy to design product hardware to use the imp,” he says. “There are two imp models, a card that can be inserted into an SD-type socket or an on-board module that is soldered into your product. Each version has advantages and disadvantages.”

Regarding software, Bachiochi says:

“Developing an imp application requires two parts to provide Wi-Fi access to your project: the device code (running in the imp) and the agent code (running on the imp cloud). The imp cloud, which is your connection to your device via the imp APIs, provides you with a development IDE. Web-based development means there is nothing else you need to purchase or install on your PC. Everything you need is available through your browser anytime and anywhere.”

Bachiochi also discusses the Electric Imp platform’s broader goals. While an individual can use the imp for device connectivity, a bigger purpose is to enable manufacturers to provide convenient Internet access as part of their product, Bachiochi says.

“The imp has two costs: The hardware is simple, it currently costs approximately $25 for an imp card or module. If you are using this in your own circuit within your own network, then you’re done,” he says. “If you want to roll out a product for sale to the world, you must take the next step and register for the BlinkUp SDK and Operations Console, which enable you to create and track factory-blessed products.”

BlinkUp, according to the Electric Imp website, integrates smoothly into apps and enables manufacturers and their customers to quickly connect products using a smartphone or tablet. The Operations Console enables tracking product activity and updating product firmware at any time, Bachiochi says.

The imp offers more than a low-cost way for DIYers and developers to connect devices to the Internet, Bachiochi says. A designer using the imp can save project costs by eliminating a microcontroller, he says. “Almost any peripheral can be easily connected to and serviced by the imp’s 32-bit Cortex M3 processor running the imp OS. All code is written in Squirrel.”

Bachiochi’s comprehensive article about his imp experience and insights can be found in the March issue, now available for membership download or single-issue purchase.

Embedded Wireless Made Simple

Last week at the 2013 Sensors Expo in Chicago, Anaren had interesting wireless embedded control systems on display. The message was straightforward: add an Anaren Integrated Radio (AIR) module to an embedded system and you’re ready to go wireless.

Bob Frankel demos embedded mobile control

Bob Frankel of Emmoco provided a embedded mobile control demonstration. By adding an AIR module to a light control system, he was able to use a tablet as a user interface.
