Episode 51 — Product Development

Saturn V ConstructionIn this episode we talk about product development with electrical engineer Dave Young, who is an author, educator, and small business owner.

  • Brian has been fortunate enough to be involved in new product development for much of his career.
  • Many firms try to avoid a technology push, in which a novel technology is introduced to the market. However, some authors claim that technology push can be a winning market strategy.
  • An alternate marketing approach, known as “market pull” or “product pull,” is to wait for consumers to request a particular product and allow that demand to “pull” the product into the marketplace.
  • Our guest is Dave Young, who previously joined us on The Engineering Commons for an episode about STEM Education.
  • Dave’s interest in engineering deepened as he tinkered with “X10” home automation modules as a teenager.
  • We learn from Dave why it is always important to turn off one’s soldering iron when suspending work for the evening.
  • Carmen and Dave share a common view on writing code; they would prefer if someone else was doing it!
  • Dave is a co-founder of Blue Stamp Engineering, a summer program which encourages high school students to build projects about which they are truly passionate. Programs are currently active in New York, Houston, San Fransisco and Denver.
  • Our guest is also a frequent contributor of articles to the electronics community known as Element 14.
  • In addition to articles about entrepreneurship, Dave likes to write about Cadsoft Eagle, an electronic design automation program.
  • According to Dave, element 14 is the place to go to ask questions about the credit card-sized computer board known as Raspberry Pi.
  • First-time engineering entrepreneurs often fall into the trap of believing that building a “better mousetrap” will automatically lead to economic success.
  • The term complex sales refers to the process of dealing with the many requirements of selling to a large enterprise.
  • Dave has been running his consulting business, Young Circuit Designs, since 2010.
  • To get product development started, Dave enjoys sitting down with a client and having a “fun conversation,” in which all manner of product ideas are considered, without regard to practicality.
  • Dave will return to the client with a “menu” of between 2 and 10 product concepts that he thinks merit further consideration.
  • It’s hard to guess which ideas will take off in the marketplace; Dave says he would have never guessed that the Snuggie would become a great success.
  • Clients of our guest’s consultancy are located across the United States, and have come from as far away as Nairobi.
  • In Dave’s work, the intellectual property (IP) typically belongs to the client.
  • One of Dave’s clients is BrewJacket, the company bringing the Kickstarter-funded Lager Jacket product to market for home-brewers who can’t keep their lagers cool enough during the fermentation process.
  • The Peltier effect can be used to move heat across an electrified junction of two dissimilar conductors.
  • Carmen expresses his concern over worts being put to waste while testing the Lager Jacket product.
  • Dave has developed a double-kettle brewing system where he and a friend can boil worts at the same time.
  • Carmen is thinking about one day entering a beer recipe in an annual contest held by the Raleigh Brewing Company.
  • Dave recently posted an article about making custom Arduino boards.
  • Our guest’s advice: “Always do awesome stuff!”
  • Dave can be reached on the web at Blue Stamp Engineering and Young Circuit Designs. He posts on Twitter as @DaveYoungEE and @BlueStampEng. Additionally, there is a Facebook page for Blue Stamp Engineering.

Episode 43 — Context

contextualelectronicsWe talk about context and learning with Chris Gammell, founder of the Contextual Electronics series of instructional videos.

  • Adam’s favorite lab course in school was Bituminous Materials, which investigated the properties and characteristics of asphalt.
  • Our guest, Chris Gammell, recently tweeted about Christmas Ale from the Great Lakes Brewing Company, and we inquire about his affection for this particular beer.
  • Chris took a few photos inside the brewery during a recent tour:

  • A list of Christmas beers (from a few years back) can be found on the Draft Magazine website.
  • Jeff mentions a cooling jacket for brewing lagers that he originally saw on Kickstarter.
  • Chris has recently launched a venture, Contextual Electronics, which aims to teach practical skills to those interested in electronics.
  • An interactive teaching method, known as Peer Instruction, was created by Harvard Physics professor Eric Mazur to overcome the difficulty that experts have in teaching concepts to beginners.
  • A book titled How to Teach Adults provided our guest with some insights about how to organize his instructional material.
  • Chris surveyed listeners of The Amp Hour podcast to determine what subject matter should be included in his instructional videos.
  • Some existing online resources, in the area of electronics, include Dave Jones’ EEVblog, the Curious Inventor website, and videos by Ben Krasnow, Jeri Elsworth and Alan Wolke.
  • Conceptual Electronics is using the open source program KiCad for designing printed circuit boards (PCBs).
  • Massive open online courses (MOOCs) are currently a popular topic in the education community.
  • Chris has been working with a beta-test group of students to smooth out the rough edges of the course.
  • Our guest took inspiration from instructional programs such as Destroy All Software and cadjunkie.
  • Fedevel Academy offers a training program for Altium Designer.
  • An introductory video program titled Getting to Blinky is available on the Contextual Electronics YouTube channel.
  • Chris is quite pleased with his experiences using Vimeo for video distribution. He has already produced 150 videos for his instructional program.
  • On a monthly basis, Chris gets together with the Charged Conversation group, comprised of electronics professionals from the Cleveland, Ohio area.
  • One of our guest’s sources for marketing ideas is Seth Godin, who often talks about the power of story-telling.
  • A project dedicated to creating all the tools needed to build a small village is Open Source Ecology.
  • More information about Chris’s instructional program is available on the Contextual Electronics website.
  • You can follow Chris on Twitter as @Chris_Gammell, and can listen to his weekly podcast with Dave Jones at The Amp Hour.

Episode 42 — Six Sigma

Normal_Distribution_PDFGuest Erica Lee Garcia explains the role of process improvement tools such as Six Sigma, Lean Manufacturing, and Statistical Process Control in this episode of The Engineering Commons podcast.

  • Although process improvement tools are widely used in manufacturing, not all engineers are familiar with their usage.
  • Our guest is Erica Lee Garcia, a Professional Engineer from Canada, who is also the owner and CEO of Erica Lee Consulting.
  • One might have expected Erica to go into civil or mechanical engineering based on her childhood activities.
  • Erica majored in Materials and Metallurgical Engineering at Queen’s University in Kingston, Ontario.
  • Our guest started her career working for a firm that produced powdered metal products.
  • In trying to determine why conveyer belts kept breaking in a sintering furnace, Erica got her first exposure to the continuous improvement process.
  • Six sigma is all about getting rid of variation, while the lean method is all about getting rid of waste.
  • Statistical process control (SPC) is a control scheme used for process analysis and monitoring.
  • Kaizen refers to a philosophy focused on continuous process improvement. The term has recently come to mean a concentrated effort in dealing with a particular issue over a short period of time; such an activity may also be referred to as a “kaizen blitz” or “kaizen event.”
  • Dr. Jeffrey Liker, a professor of industrial engineering from the University of Michigan, published The Toyota Way in 2003. The book details 14 principles that provide the framework for Toyota’s continual improvement system.
  • The Kaizen Institute and the American Society for Quality are organizations that promote the continuous improvement of people, processes, and systems.
  • Erica has run into situations where engineers and accountants have wildly differing interpretations of the same underlying data.
  • Adam asks how projects can continue to improve after all the “low-hanging fruit” has already been gathered.
  • Bruce Tuckman introduced the “Forming — Storming — Norming — Performing” model of group development in 1965.
  • The phases of a Six Sigma project are “Define — Measure — Analyze — Improve — Control,” also known as DMAIC, for short.
  • Erica addresses how one might deal with non-normal data while engaging in process improvement.
  • Process variations are designated as resulting from “common” and “special” causes.
  • Jeff notes that the 2007 financial crisis has been partially blamed on fat-tailed distributions that were distinctly different from assumed Gaussian probabilities.
  • Erica mentions a video presentation by Dan Milstein talking about the 5 Whys, a tool used in process improvement to determine cause and effect relationships.
  • Brian inquires about the minimum production volumes required to justify initiating a continuous improvement project.
  • Jeff raises the notion that Six Sigma may kill innovation. That position is refuted by Erica, who notes that there is a method of Design for Six Sigma.
  • While the United States celebrates National Engineering Week for seven days in February, the entire month of March is set aside as National Engineering Month in Canada.
  • Our guest believes that aspiration messaging is more effective than descriptions of day-to-day duties when undertaking engineering outreach.
  • The Changing the Conversation campaign, sponsored by the National Academy of Engineering, is mentioned by Erica. She notes a video from the site, titled “If it weren’t hard, it wouldn’t be engineering.”
  • Advice for early- and mid-career engineers is provided by Erica on her website, EngineerYourLife.net.
  • Marc Garneau is a Candadian engineer, astronaut, and politician.
  • Brian comments that engineering is a “world of niches,” in which engineers often have radically different duties and assignments, even if working in the same discipline, or for the same company.
  • Erica can be found on Twitter as @engineeryrlife. She can also be contacted via her website.
