When Is An Engineer Not An Engineer? When He’s A Canadian Engineer

In medieval Europe, many professions were under the control of guilds. These had a monopoly over that profession in their particular city or state, backed up with all the legal power of the monarch. If you weren’t in the guild you couldn’t practice your craft. Except in a few ossified forms they are a thing of the past, but we have to wonder whether that particular message ever reached Western Canada.

An electoral candidate with an engineering degree who practices what any sane person would call engineering, has been ordered by a judge to cease calling himself an engineer. The heinous crime committed by the candidate, one [David Hilderman], is to not be a member of the guild Association of Professional Engineers and Geoscientists of B.C. We get it that maybe calling a garbage truck driver a waste collection engineer may be stretching it a little, but here in the 21st century we think the Canadian professional body should be ashamed of themselves over this case. Way to encourage people into the engineering profession!

Here at Hackaday, quite a few of us writers are engineers. Stepping outside our normal third person, I, [Jenny List], am among them. My electronic engineering degree may be a little moth-eaten, but I have practiced my craft over several decades without ever being a member of the British IEE. No offence meant to the IEE, but there is very little indeed they have to offer me. If the same is true in Canada to the extent that they have to rely on legal sanctions to protect their membership lists, then we think perhaps the problem is with them rather than Canadian engineers. You have to ask, just how is an engineering graduate who’s not a guild member supposed to describe themselves? Some of us need to know, in case we ever find ourselves on holiday in Canada!

Lonnie Johnson, Prolific Engineer And Hero To Millions Of Kids (Even If They Don’t Know It)

The current generation Super Soaker XP30. (Hasbro)

To be a child in the 1970s and 1980s was to be of the first generations to benefit from electronic technologies in your toys. As those lucky kids battled blocky 8-bit digital foes, the adults used to fret that it would rot their brains. Kids didn’t play outside nearly as much as generations past, because modern toys were seducing them to the small screen. Truth be told, when you could battle aliens with a virtual weapon that was in your imagination HUGE, how do you compete with that.

How those ’80s kids must have envied their younger siblings then when in 1990 one of the best toys ever was launched, a stored-pressure water gun which we know as the Super Soaker. Made of plastic, and not requiring batteries, it far outperformed all squirt guns that had come before it, rapidly becoming the hit toy of every sweltering summer day. The Super Soaker line of water pistols and guns redefined how much fun kids could have while getting each other drenched. No longer were the best water pistols the electric models which cost a fortune in batteries that your parents would surely refuse to replace — these did it better.

You likely know all about the Super Soaker, but you might not know it was invented by an aerospace engineer named Lonnie Johnson whose career included working on stealth technology and numerous projects with NASA.

Why I Got The Job

Hackaday readers are a vast and varied bunch. Some of us would call ourselves engineers or are otherwise employed in some kind of technical role. Others may still be studying to gain the requisite qualifications and are perhaps wondering just how to complete that final leap into the realm of gainful employment. Well, this one’s for you.

What sort of job are you looking for?

You might be a straight, down the lines, petroleum engineering graduate who’s looking to land a job in the oil and gas industry. Conversely, you might be an arts student who’s picked up a few skills with electronics over the years and are keen to gain a position doing grand installation pieces for musuems or corporate clients.

There’s a broad spectrum of jobs out there that require high-level technical skills, and my first piece of advice is that you shouldn’t limit yourself. There are things you can do to keep your options open, even over a long career – these could pay dividends when you’re looking for a seachange.

Puzzle Alarm Clock Gets Couple Up In The Morning

[BrittLiv] and her boyfriend got in one too many fights about who set the alarm. It’s the only argument they seem to repeat. So, true to her nature as an engineer, she over-engineered. The result was this great puzzle alarm clock.

The time displayed on the front is not the current time. Since the argument was about alarm times in the first place, [BrittLiv] decided the most prominent number should be the next alarm. To hear the time a button (one of the dots in the colon) must be pressed on the front of the clock. To set the alarm, however, one must manually move the magnetized segments to the time you’d like to get up. Processing wise, for a clock, it’s carrying some heat. It runs on an Intel Edison, which it uses to synthesize a voice for the time, news, weather, and, presumably, tweets. It sounds great, check it out after the break.

All in all the clock looks great, and works well too. We hope it brought peace to [BrittLiv]’s household.

A Home CNC Built By Someone Who Knows Their Stuff

[thisoldtony] has a nice shop in need of a CNC. We’re not certain what he does exactly, but we think he might be a machinist or an engineer. Regardless, he sure does build a nice CNC. Many home-built CNCs are neat, but lacking. Even popular kits ignore fundamental machine design principles. This is alright for the kind of work they will typically be used for, but it’s nice to see one done right.

Most home-built machines are hard or impossible to square. That is, to make each axis move exactly perpendicular to the others. They also neglect to design for the loads the machine will see, or adjusting for deviation across the whole movement. There’s also bearing pre-loads, backlash, and more to worry about. [thisoldtony] has taken all these into consideration.

The series is a long one, but it is fun to watch and we picked up a few tricks along the way. The resulting CNC is very attractive, and performs well after some tuning. In the final video he builds a stunning rubber band gun for his son. You can also download a STEP file of the machine if you’d like. Videos after the break.

Talking Big Changes At SparkFun With Nathan Seidle

SparkFun, you know them, you love them. They list themselves as “an online retail store” but I remember them for well-designed breakout boards, free-day, videos about building electronics, and the Autonomous Vehicle Competition. This week SparkFun turned my head for a different reason with the announcement that [Nathan Siedle], founder and CEO will be stepping down. He’s not leaving, but returning to the Engineering department while someone else takes the reigns. I spoke with him yesterday about what this means for him, the company, and what SparkFun has planned for the future.

Stepping Down Without Saying Goodbye

[Nate] founded Sparkfun in 2003 while still working on his Electrical Engineering degree from the University of Colorado Boulder. He cites wanting to return to his engineering roots as the reason for his title shift, which won’t happen for at least 9 or 10 months. It’s the concept of leaving the CEO position without leaving the company that raises many questions in my mind.

The Model Engineer

engineer

 

As a child, [Mike Chrisp] saw a film featuring one of the great narrow gauge English locomotives. While the story was inordinately heartening, as soon as he walked out of the theatre, [Mike] said to himself that he had to have one of these locomotives. Thus began a lifelong adventure in model engineering.

[Mike] builds model locomotives and other steam-powered means of motive power. Everything from five-inch gauge locomotives to small steam tractors is liable to come out of his small workshop, all built with the machining and engineering excellence only a lifetime of experience can provide.

As for what drives [Mike] to stay in his workshop for long hours, he says his shop is just a place to be, a place to tinker, and a place to simply think about things, even if his hands aren’t getting dirty.  There’s something beautiful about that, even if [Mike] were to hide the products of his skill away from the world.
