Whatever Chuck draws, the result is neat, clear, and interesting. His techniques are equally so, as a close examination reveals. The drawings are usually executed first in pencil, and then finished in ink. I hesitate to say "traced," because the ink lines follow rather than exactly overlay the light pencil ones. Sometimes, after the ink has dried, he erases the pencil lines. These are techniques I learned in mechanical drawing courses in high school and in college as an engineering student, and seeing them used by a master brings back fond memories of those days at the drafting board.
A letter from Chuck is hard to miss in the mail, for the envelope is always addressed with either elaborate calligraphic flourishes or fancy and whimsical artwork. He does not consider himself an artist, and so when he draws cartoons of people or animals he often traces them from some source, such as a magazine. He also employs a lot of color on his envelopes, as he does on the drawings inside them. He typically uses either colored pencils or watercolors; something that was commonly done in nineteenth-century engineering drawings, making the best of them truly works of art.
I often wonder whether the postman sorting our mail stops for a moment to enjoy Chuck's entertaining envelopes. They may be but small packages among the plethora of slick and heavy mail-order catalogues that clog our mailboxes nowadays, but they always carry the distinct mark of being hand-addressed and hand-drawn -- hand-designed -- and that alone makes them something to admire among all the computer-generated and personalized impersonal material. I know that I stop to admire a Chuck Siple envelope before I open it, and I open it carefully so that I can preserve it along with its always interesting contents.
With the near-ubiquitous adoption of computer graphics, a meticulous draftsman like Chuck Siple may be a thing of the past, but to me his eye for detail keeps him as perceptive a critic of design as he ever was. Though he has the hands of a draftsman, he has the mind of an engineer. Computer-generated drawings may be the new standard, but I doubt that any graphics program will ever become an engineer's pen pal.
Yes, I have had several hotshot young bosses - what upsets them most is when I show them up. It is okay to disagree with your boss, UNLESS it turns out your boss is wrong, and you are right. I have fixed machines that engineers and technicians with several years more education, several years more experience, and several years more seniority couldn't fix. But now I am being immodest.
Sure, the world could survive without my skills. Are you suggesting that the world could not survive without you ? One day, many years from now, you will look back on this and wonder why it seemed so important at the time.
I have found that getting angry and tense doesn't help, so now I just try to find the humor in watching young hotshots flail and founder. And if they do eventually ask for my help, I do try to help them.
Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
