Hot/Neutral/Ground

With Brock U Prof. Don Cyr and Prof. Pei Jingang at Foshan University School of Art and Design, November 2011

At the end of this month, I’ll embark on my ninth trip to China, to promote NSCAD and the MDES program in Beijing, Shanghai and Guangzhou. Last fall, while in the Pearl River Delta region, a small group of four of us took a 30-minute drive from our hotel — The “Good International Hotel of Guangzhou” * — to Foshan University. Foshan is the third largest manufacturing city in the Pearl River industrial region, after Guangzhou and Shenzhen. There I met Prof. Pei Jingang, Head of the School of Art and Design. Prof. Pei showed me a gallery full of student-made product design prototypes by students. The school has an arrangement with RMIT where students from Melbourne work with local Foshan manufacturers to develop prototypes of their designs. Some of these prototypes have even been manufactured, such as the set of steel cookware that was on display.

This year, I’ve been invited to stay on in southern China to conduct a workshop with the Foshan design students on developing a new design for an electrical power bar — the device that you plug into a wall that has 6, 8 or more sockets. These power bars are very useful when you have small electronics that use square adapters. The design problem is that the size of the adapters often prevents access to many of the remaining power outlets. Some excellent solutions are already on the market, notably power strips that have sockets that rotate or reconfigure in some way. As I say, some of these products solve the problem admirably, but one objection — one that will be settled over time and use — is that these movable socket contacts will eventually wear down, causing interruptions, sparking, or even fires. My idea is to accept that there will be large plug adapters and regular-sized plugs, and rather than providing a means to articulate and spread out the sockets, I propose to make more of them and fix them in a small space. I’ll double the density of the outlets by slot-sharing and interlocking the sockets at 0/90/180 and 270-degree angles. This fixed form will allow a greater flexibility in access. There are several consumer electrical manufacturers in the Foshan area and I hope one of them can be involved in the development process.

I’ll be in Foshan from November 14 to 23, and I’ll hopefully be able to give blog updates — GFC notwithstanding — on the progress of this project.

QSL Card

As a teenager, and with a parent in the broadcasting industry, I was fascinated with radio and television. A hobby of mine was collecting QSL cards from around the world. I collected QSL cards from AM, FM and shortwave radio stations. The other day, I was looking in my archives for something else, and I found the QSL card from Radio Peking, posted on September 30, 1972. The letter, typed on onionskin paper and in perfect English, invited me to listen to some of its special programs, which included “Selected Readings from Mao Tsetung’s Works”, and “Selected Readings from the Works of Marx, Engels, Lenin and Stalin”. Later, I received some English-language magazines. My progressively liberal parents, who were young adults in the early 1950’s—during the ‘red scare’ era—tended to look a little askance at these deliveries.

Seeed Studio Visit – Shenzhen, China

(Wuhan, China) On Monday I visited Seeed Studio, a small but growing tech startup in Shenzhen. They specialize in open source hardware, and are known for the Seeeduino, an Arduino microcontroller board. Seeed makes open source “brick” addons that allow sensor and actuator connections to the Seeeduino without soldering and they provide economical starter kits that are perfect for our students at NSCAD University.

They generously provided me with a sample Seeduino, and two kits: the “Electronic Brick Starter Pack” and the “Catalyst” kit that they have prepared for Make magazine for my lecture at Shenzhen Polytechnic that afternoon. I’ve used their bricks before and find them very convenient for learning how to use the various sensors, motors, LEDs and other actuators, though I have to admit that I broke a light sensor early on when I plugged it into the brick the wrong way around. Apart from that silly mistake, the brick system is robust and well-designed.

Two of the principals, young engineers Eric and Fan, were my hosts. They showed me a beta version of their soon-to-be-released DSO nano, a small handheld digital storage oscilloscope for people like me. It looks like an iPod Touch, but with a button rose at the right. They tell me that they would like to use a complete ‘glass interface’ like the iPod with their next version of the product.

Eric brought out a development prototype of their Rainbowduino called the 3D RGB Cube, a 3D matrix of RGB LEDs that connect smartly to the Seeeduino. With this system there are no worries about current requirements, all you need to do is plug it into the microcontroller and ensure that you give it enough juice.

Now, off to Beijing!
