Tom Kibalo

Location: Annapolis, MD

Education: BS, Electrical Engineering (City College, NY), and MS Electrical Engineering (University of Maryland)

Occupation: Tom is Principal Engineer of a large defense firm and CEO of KibaCorp, which he says is “dedicated to innovative educational technologies for the hobbyist, student, and practicing engineer.” He is also an adjunct faculty member at a local community college.

Member Status: Tom has been a subscriber for more than eight years.

Technical Interests: He is interested in robotics, embedded programming, microcontrollers, wireless applications, and engineering education.

Most Recent Embedded Tech-Related Acquisition: Tom’s most recent purchase was a Raspberry Pi with direct GPIO connections.

Current Projects: He is working on a battery-powered Wi-Fi sensor network that uses low-power Microchip Technology PIC32 components. (His project is shown in the photo.)

Thoughts on the Future of Embedded Technology: Tom thinks these are “exciting times where system-on-a-chip (SoC) technologies are extending the domain of embedded applications with Linux OS and a large base of language libraries.”

Location: Menlo Park, CA

Education: BS and MS, University of Utah

Occupation: Software Developer

Member Status: John has been a subscriber since 2002.

Technical Interests: His interests include user interfaces for embedded systems, field-programmable gate array (FPGA) development, and embedded Internet development.

Most Recent Embedded Tech-Related Purchase: John recently purchased a power supply for one of his designs.

Current Projects: He is currently working on a custom light controller for strings of progammable LED lights.

Thoughts on the Future of Embedded Technology: John feels that smartphones have raised everybody’s expectations for how we interact with everyday things (e.g., cars, appliances, household control, etc.). “Either the phone becomes the interface (via the network) or the gadgets need touchscreen displays,” John said.

Gordon Dick

Location: Stony Plain, AB, Canada (Stony Plain is suburb of Edmonton, home of the Oilers)

Education: MS, the University of Saskatchewan in Saskatoon, SK, Canada

Occupation: Gordon is semi-retired. He used to be an Electronics Technology and Computer Engineering Technology instructor at the Northern Alberta Institute of Technology in Edmonton.

Member Status: Gordon says he used to have Circuit Cellar issues dating back to 1995. “We were getting issues under the ‘college program’ then,” he explained. Later, his department subscribed to the magazine and the issues came directly to Gordon. Then he obtained a personal subscription. “I still have my paper copies containing my own articles. And we bought the CDs to get all the back issues.”

Technical Interests: Gordon has always been interested in electronics, both as a hobby and as a profession. He focused first on audio, then turned to microcontrollers. He has built a few microcontroller-based instruments, some of which have been the topics of his Circuit Cellar articles. “For a time, I was involved in building microcontroller-based dog training equipment. I built a microcontroller-based weather station, which I also wrote an article about. I have several microcontroller-based projects in my home that are specific to my needs. My cold-room temperature controller is microcontroller-based, for example.”

Most Recent Embedded Tech-Related Acquisition: Gordon bought a SparkFun Electronics FG085 frequency generator kit.

Current Projects: He is working with a Freescale Semiconductor MPL3115 pressure/temperature I2C transducer for his weather station. “It has amazing barometric pressure resolution,” Gordon explained.

Education: MS in Chemistry, Moscow State University, PhD in Genetics and Bioinformatics, University of Cologne, Germany

Occupation: Research scientist

Member Status: He has been a subscriber for a year.

Technical Interests: Alex is interested in low-level hardware programming and high-voltage electronics, including vacuum tubes.

Most Recent Embedded Tech-Related Acquisition: He recently received a single-board fanless PC with a solid-state hard drive as a gift.

Current Projects: Alex is further developing the NakedCPU platform he wrote about in his two-part article series, “The NakedCPU,” (Circuit Cellar 259–260, 2012).

Thoughts on the Future of Embedded Technology: Alex says he’s worried that embedded solutions are becoming less transparent. He remembers working with one system that had several DVDs of examples and libraries but it didn’t have a comprehensive guide to the system’s architecture. “As a researcher and someone who wants to get to the bottom of things, such a situation is frustrating. This is certainly my personal researcher’s view. I am not commenting on the application side of increasingly complicated embedded systems.”
