Pocket Prototyping

Dear Engineering Stories followers, It has been a great #engineering#career so far including my #coaching of about 20 teams in 20 years at the local university. I’ve noticed a few things over the years that could help newer engineers be more successful, and I offer ‘Pocket #Prototyping‘ pointers in this article in the BYU Design Review. Please read it and then share it with your colleagues (and ask them to share it), especially with those just getting started in engineering and #design who need #mentoring. Thanks, Ken

Engineering Project – Re-inventing the 35mm Color Slide Digitizer

I can’t help myself. When I get it in my head to create a solution or solve a problem, it doesn’t matter that it has already been done before. I love finding a quick, in-expensive solution to a need. In the 1970s and 80s, my film of choice was 35mm Color slides; I enjoyed making slide shows.

I haven’t yet digitized these photos, so my kids haven’t seen many of them, including pictures with them as small children. It’s time to change that.

Now I know that I can purchase a digitizer for 35mm slides; but, “where’s the fun in that?” I have a smart-phone with a digital camera and amazing pixel resolution, and I understand the basics of light and optics to give it a shot. So one evening, I grabbed my grand-kids favorite box of Lego’s® and went to work, for fun of course.

Requirements: 1) a way to hold the slide a fixed and steady distance from the camera, 2) a way to illuminate the image, and 3) a digital representation of the image good enough for social media.

Concepts: 1) a structure to hold a light source, a light diffuser, a slide holder, and the camera (see picture), try variations and lengths (don’t worry about the color of the structure.)

IMG_1541

Design: an electric Christmas candle mounted to a base, a light diffuser cut from a white paint bucket lid or plastic putty knife, a support for the slide, and an adjustable support for the camera

Image Processing: place slide in holder, turn on the light, avoid stray light, assure that the camera does not focus on the diffuser, focus on the slide, take the picture, crop the image, adjust the color as necessary, post and enjoy pictures with family and friends

Lessons Learned: the camera can’t get close enough to the slide to utilize all of the camera pixels therefore some resolution is lost (still okay for social media)

Conclusion: Great project, lots of fun, and included one of my favorite activities; that is, walking through a hardware store looking for suitable substitutes for what I really need. In this case, a high density plastic light diffuser. Enjoy the results, and keep on engineering. Go ahead; share this with your friends. Better yet, get that old box of slides out of your attic or basement, and share them with family and friends.

Ken Hardman tells quick engineering stories in a video

Recently, we held a family “talk” night where family members came prepared to give a talk or presentation on a topic of strong interest. What do you think I spoke about? Engineering, one of my favorite topics. The event was video recorded. Join me while I share two quick Engineering Stories on why I enjoy engineering and why Engineering is a blessing to all. Share the video; share my Engineering Stories.

Mechanical Engineering Student Projects

Announcement – Engineering Stories in Paperback

Engineering Stories is now in paperback! Seven stories illustrated, formatted, and published in a handsome professionally bound book for some ernest reading. Listen to these endorsements by engineering academic professionals on the back cover.

“A fabulous collection of realistic engineering adventure stories! Ken Hardman connects the design and development process we teach in engineering school to the exciting challenges faced every day in real engineering practice.” Steven D. Eppinger, Professor of Engineering Systems at MIT, co-author Product Design and Development

“Ken Hardman’s stories about engineering are a joy to read. In them he captures the excitement of engineers developing solutions to realistic technical problems. By describing the engineering process through fictional characters in fictional settings, Hardman invites the reader to participate in the adventure of invention and discovery.” Henry Petroski, A.S. Vesic Professor of Civil Engineering, Duke University, and author of, among other books, To Engineer Is Human, To Forgive Design, and An Engineer’s Alphabet.

Engineering Stories are for:

  • The high school student who wonders if engineering is for them,
  • The K12 career counselor or teacher who needs more depth in explaining engineering to students,
  • The parent or grandparent or friend who would like to encourage a youth toward a satisfying, useful, and profitable career,
  • The college engineering freshman who is deciding what major to declare,
  • The older college engineering student who cries for ways to apply their engineering academics, anxious to experience real engineering, real companies, and real teams, and
  • The young engineering professional who wants to live the engineering experiences of there peers, gaining encouragement and insight to move forward in their career.

“Ken Hardman has done a masterful job—even spellbinding—in depicting what real Science, Technology, Engineering, and Math (STEM) projects, and the people and circumstances involved in them, are actually like in the real world! Having myself been involved for more than fifty years in the types of projects that Ken writes about—and the use of case studies in engineering education for more than forty years—I can say without equivocation that Ken’s case writing ability is superb! Page after page challenges you to use your creative juices, and you feel as if you are right in the lab, conference room—or wherever—huddled around some hardware as part of a team effort working through the technical, as well as the people issues, to get the problem solved! Each engineering story has been carefully chosen to share important skills, topics and essential abilities of great engineers and scientists at work! These stories will help you experience—just about as close to first hand as possible—the joys of creation and problem solving which result from learning and applying skills in a world where all of us have the opportunity to make things better.” Robert H. Todd, PhD, P.E., Fellow of The American Society of Engineering Education, Professor Emeritus Department of Mechanical Engineering Brigham Young University

Engineering Stories has boiled down the relationship between an engineering education and real-world engineering situations to its core! I know of no better introduction for engineering students preparing to work in industry. Anybody seriously considering a career in engineering will benefit from and enjoy reading Engineering Stories!” Braden Hancock, Mechanical Engineering Student at Brigham Young University, ASME 2012 Kenneth Andrew Roe Scholarship recipient

My Journey to Engineering – Part 2 “Drafting to Engineering”

(Continued from Part 1)

I was ten and a half years old when Neil Armstrong stepped onto the lunar dust and into the history books. Wow, I thought, looking up that evening at the moon, half illuminated by the setting sun, how amazing is that? My childhood thoughts of “The Man in the Moon” were changed forever.

At my dad’s work back on earth, they manufactured wood panel products with routed or grooved patterns on the panel surface.  They had an automated machine that held the panel upright while a vertical and horizontally moving, 2-axis router would carve a design based on data from a punched tape and tape reader (yes, a punched tape; remember this was the 50’s and 60’s).  On one occasion, they were having trouble getting the plunge axis to work.  This axis would thrust or retract the router blade into or away from the panel.  If the router did not plunge or retract correctly, it would carve where it shouldn’t or it would miss carving where it should.  If this happened, they would have to scrap the panel at some expense.  They invited me, the managers 10-year-old son, to assist the machine by making sure that when it was supposed to plunge, that it did, and that when it was supposed to retract, that it did.  I stood in sawdust close to the machine and watched a light on the computer or tape reader and if the router did not retract, I would grab a bar and pull it out and vice versa.  The workers labeled me, ‘The Automated In and Out.’  Even though faulty, I thought that machine was amazing.

After routing some of their products, they covered them with thin wood-grain vinyl by coating the wood surface with adhesive, then vacuum-applying the plastic to the panels or other furniture (In the 30’s and 40’s, wood-grain vinyl was also used on cars called Woodies).  In some cases this plastic became a hinge for folding mitered panels into a box shape. How ingenious; how clever. Searching the internet, I found an old newspaper article on the company.

I enjoyed math, wood & metal shop, photography, guitar, hiking, skiing, and backpacking. I even used my mom’s sewing machine to make my own backpack from a kit. The backpack was nice, but I was more fascinated with the gears and shafts inside the sewing machine (when my mom wasn’t looking). In shop I made a model sailboat, a footstool, a gavel, a book shelf and a cedar chest. I enjoyed the creative artistic aspects of photo composition as well as chemical development of film and paper. I had a darkroom and equipment for developing black and white film and paper. I took my camera hiking, skiing, and to most activities.

Before the days of portable stereo’s, I built a wooden box and mounted an old 8-Track car stereo inside, with power supply and speakers and took it on outings with friends (No vinyl on this one). I enjoyed basic electrical wiring.

During high school, I took drafting every year.  I enjoyed it; my mechanical pencil was cool.  I enjoyed drawing mechanical objects and architectural structures and renderings.  I thought I was pretty good at it and for a time wanted to become an architect.  Working for my father over the years gave me lots of exposure to drawings, cabinetry, and construction sites; however, as I worked on wood products, I seemed more interested in the machines than in the items being built by them.

At the university I toured campus, talked to professors, and took aptitude tests. I narrowed it down to Communications and Engineering. No one in my immediate family was an engineer but it was drawing me in. Engineering seemed more practical and interesting because I wanted to design mechanisms and machines. I declared my major as Mechanical Engineering. I loved statics, dynamics, and kinematics. I would come home from numerical methods class and program the days learning into my Atari 800 (a personal computer with a whopping 16 kilobytes of RAM memory, no flash memory and no disc drive. I used a magnetic cassette tape to store my programs) I was proud of my accomplishments.

After a little research (before Google and even the internet) I figured out how to reprogram my computers’ joy-stick port for ‘output’ and used it to control a little electric motor I took from an old printer.

During college I continue to work for my dad. He allowed me (with little or no budget) to build a few simple gadgets and machines to help production. While cutting or assembling a thousand drawers for hotel room dressers and night stands, my mind was always on efficiency, “How can this job be done faster and more accurate?” I even explored books on Operations Research and the classical “Cutting Stock” problem so I could write software to help decide how to get the most out of a sheet of plywood.

Yes, I was drafted, no, drawn to engineering and my mind was always solving problems. I enjoyed the challenge and I couldn’t wait to graduate and go to work as a real engineer.
