The Importance of Knowing Everything

This entry is part 2 of 3 in the series MMA of Engineering

IMG_0457.JPG When I started at UF, I didn’t really know what to expect. I knew I would learn “engineering” stuff in the “mechanical” category, but really I had no idea what I would learn.

Prior to college, I never had a “normal”  job. Instead of stocking shelves at the local supermarket, or the water park, or bussing tables, I worked for my grandpa. He’s my hero in case you didn’t already know. It started when I was old enough to pull weeds (3 or 4 maybe? it was a long time ago…); he would give me $.50 to fill a bucket with weeds from the shop yard. As I got older and learned to do more demanding tasks, he paid me more. By the time I was a senior in high school I think he was paying me $8/hr, which was pretty good at that time.

It was also fun. I learned to drive a Case 580 front-end loader when I was 8. By the time I was 12 I could safely operate every basic tool in the shop (and there are a LOT). At 14 I could stick weld pretty well, and at 16 I could braze with an oxy-acetlyne rig. At 18 I was cranking precision parts out of a lathe and milling machine and helping with aluminum casting. At this point, I had more practical experience than any of my soon-to-be mechanical engineering cohorts.

Monkey Wrench

Monkey Wrench

As an aside, a good friend of mine (in food science, not ME) took a design class and had to tell an engineer what a pair of dics (pronounced dikes) is; It was rare to find someone who knew a monkey wrench was an actual tool; and to this day, without a picture, no one believes me that I once had a drill that drills square holes.

Needless to say, when I got to college, the engineering theory that was taught in my classes only reinforced the observations of my previous 10+ years of shop apprenticeship. It was actually the testing, and a pesky, well hidden learning disability that almost got me kicked out… but that’s for another post. During the <ahem> 5-1/2 years that I was there, I learned why mechanical engineering was considered one of the hardest disciplines: We were taught just about everything.

OK, not everything, but everything having to do with the physical world, and more. We learned advanced mathematics as the basis for defining and solving problems (I think I was only one class away from a math minor, and 4 or 5 away from a math major…). We learned advanced physics to understand complex moving systems. We learned chemistry to understand material behavior; thermodynamics and fluid dynamics to understand heat, mass, and fluid energy transfer; electrical engineering classes to understand electromechanical devices; control theory to make our devices function. We learned about fixed, moving, and deforming structures; Computer systems to design and analyze in the virtual world before bringing designs to the real world. We learned how to communicate with customers, integrate designs, and troubleshoot problems. We learned everything we need to design anything for anyone.

Now, you may be wondering what exactly mechanical engineers design. Well, if it involves heat, motion, lightweight structures, advanced materials, or phase changes, chances are a mechanical engineer had a hand in it. When I graduated, I really didn’t know that there were so many different career paths that a mechanical engineer could take. I spent a just less than 2 years designing HVAC and Plumbing systems, but then after a career switch I found my true calling in advanced aerospace mechanical systems. Next post I’ll show you exactly what I do… in a very abridged form.

So What Would Ya Say… Ya Do Here?

This entry is part 1 of 3 in the series MMA of Engineering

bobs-small

In any given week, I’d say I only do about 15 minutes of real, actual, work. The rest of the time I’m just doing my job. And I like my job. 

Many people ask me what I do, and the usual answer is “I design cargo systems.” The usual response is something like “Oh, that’s cool,” but I can see the internal response on their face: booooooooring. I’ll agree that to most people the statement is definitely boring on the surface, which is partly why say it. Most people don’t care, and I don’t feel like explaining to them and watching their eyes glaze over. But since I started this blog as more of a technical blog than personal (though I’ve posted more personal than technical lately) I’ll take the time to go into some details of exactly what I do, while attempting to prevent comatose boredom.

At this point I’ve realized that this post is about to embark on an adventure through the depths of my very being. It is not going to be short by any means. Since I’m normally long worded anyway, I think it will be a good idea to cut this up into a few different posts. 

When you break down the general “Engineering” field, you get a number of specific disciplines:

  • Agricultural 
  • Biological 
  • Biomedical
  • Chemical
  • Civil
  • Computer
  • Electrical
  • Environmental
  • Industrial Systems
  • Materials
  • Mechanical & Aerospace
  • Nuclear & Radiological

Most of these disciplines cover a wide range of studies, and after graduating you either go to grad school or you go to work for an industry for a specific topic within your discipline. However, there are a few disciplines that actually require significant knowledge of other disciplines. I like to call these the MMA fighters of the engineering world. IMO, these are Biomedical, Electrical, Chemical, and Mechanical, but I like to consider mechanical engineering the world champ of the MMA disciplines. 

You’ll just have to wait for my next post to hear why.

Scared of Guns

 

IMG_2028.JPGGuns are totally a guy thing. Guys like to throw rocks, make loud noises, play with fire, and try to pretend like we understand machines too complicated for our brains to handle. I know, because I’m a guy.  A firearm is basically the culmination of all primordial things “manly”. These are the reasons that I enjoy shooting.  Unfortunately you can’t overlook the fact that the reason guns were invented in the first place was to kill (hunting or war… I don’t know which came first, but I’m guessing war). I can definitely see how this reason is a good basis for being afraid of guns. With all the shootings that have happened lately, that thought can easily be reinforced.

I can’t count how many people I’ve met throughout my life who are scared of guns.  If you agree that guns scare you, I would like to share my thoughts about guns. You don’t have to agree with me,  but at least think about what I have to say.

fearFirst, I would like you to consider changing your perspective on guns from “I’m scared of guns” to “I don’t like guns”. Now this may not seem like a big difference at first, but people who are scared of guns are generally ignorant of gun operation, use, and safety. The reason is that they are “scared”, and if you are scared of something, you usually don’t want to be in the same vicinity, let alone handle and learn about that something. If you change your thinking to “I don’t like guns” then we can go to the next step and tack on, “but I respect them.” And to respect something you must learn about it.

The leap requires you to get over your “fear” of guns and actually learn about them. At this point, if you are saying “no way will I ever handle a gun” let me set up a very common situation:

Uncle Bob is on vacation for a few weeks and you said you’d house sit for him. You take your kids to uncle Bob’s house to let his dog out.  Your kids are horsing around in the living room, and all of a sudden, they knock into Bob’s favorite recliner. On of your kids says “mommy mommy, look what I found!” and points to a gun that fell out of the chair. 

kidwithgunIf you’re afraid of guns, what would you do? You have two weeks until Bob gets back, and you can’t just leave it sit there on the floor with your kids there. Any good parent would know to tell their kids to not touch it and get back, but would you know how to safely handle it? Do you know how to tell if it’s loaded? Could you unload it to make it safe in case someone else found it again? (Your kids are sure to be curious to where you put it – especially if they are boys.) 

Now that is a pretty extreme case, but there are other cases that are just as likely. Considering that there are 9 guns for every 10 people in the US, your chances of encountering a gun are pretty high. Maybe your husband forgets to put a gun away before running to the store and you have company knock on the door. Or what about having a roommate that owns a gun – could you tell if they were safely handling it? These situations are very controllable and safe, as long as you don’t flip out. Twice in my life I’ve picked up a gun belonging to someone else and found that it was loaded. Since I know how to check that a gun is safe, there wasn’t a problem.

Unexpected situations like these make it prudent for you to learn about guns, even if you don’t like them, or ever want to own one. There are many ways to learn to safely handle a firearm, and chances are that you have a respectable friend who would be willing to teach you for free. Other resources include your local Police/Shariff’s office, and many ranges offer safety classes.

I hope that, after reading this, you are willing to attempt to change your view from “fear” to “respect”. It is a big step, but learning about guns can only help you out.

I help lead a target shooting life group at my church. If you have a few minutes, check out our site:  http://sharpshooters.lifegroupcentral.com/

We generally limit our group to gun owners, but if you want to learn about guns and gun safety, we would definitely be willing to take you along on our next outing.

Yes, I’m Addicted

To anime.

Now hang on… chances are that the first thing you think of if you are not familiar with anime is something your kids watch. This is not what I’m addicted to. Anime covers such a wide range of genres, artistic styles, lengths, and ages that the word itself is misunderstood by anyone unfamiliar with it. Good anime can put 90% of hollywood movies to shame.  So what I’m going to try to do is explain it. At least explain why I like it, and why you should too.

I’ll start out with my general overview of anime. (Bear in mind that I have no education in the visual arts whatsoever, so my classifications are not based on any real categories – only my opinions) I like to break anime int 3 different distinct classifications. The first (and least interesting IMO) is the stand-alone, sitcom-style. Every episode has a plot that resolves, and you can watch any episode and be satisfied. The second is episodic anime. This (as I understand) is the classic type, and usually has a plot that extends through one season (25-26 episodes) to resolve in the last one or two episodes. Each episode is still generally stand-alone, but the sub-plots are developed throughout the season, over many episodes. The good thing about this is that there is usually a definitive end to a series. My favorite anime of all time falls into this category.

The last classification I like to refer to as epic-dramatic. When I say epic, a series in this classification can be several hundred episodes, and span years with each episode highly linear in the overall story. These are the most addictive. I’m currently addicted to one of these – I’m at episode 80 of the second actual series. I watched the first series back in college and seriously watched about 160 episodes and never saw the end of the first series. I just recently picked up watching the second series because it’s available on Hulu (which is even worse since I can watch as many as I want in a sitting).

So why is epic-dramatic anime so addictive? Because it’s epic. When the writers have limitless episodes to build a single character, plot, sub-plot, setting, etc… the level of detail for each is ridiculous. The average mini-plot for this type usually spans 3 episodes. In fact the whole reason I’m writing this is because in the show that I’m watching now, one of the main characters died in the episode I watched today. And it was a death worthy of Shakespeare. The show is about some ninjas in a made-up land (don’t laugh) and the character that died spend the last 3 episodes fighting one of the baddest of the bad guys, and lost. In the episode today it took him 15 minutes (out of the 20 minute episode) to actually die. That’s 3/4 of the episode, just to die. And the bad guy got away.

Here’s where epic anime shines. 20 episodes ago, this guy was a background character. They spent about 20 episodes bringing him to the front, developing him, and then killed him.  Amazing. The kicker – the last, most important character that was killed off was this guy’s dad, killed by the ultimate bad guy.

How would you feel if Joker killed Robin in Batman? You know Robin. You like Robin. He’s a good guy. Now he’s dead. That’s about the feeling of how killing off this guy was. Shocking enough to make me write a blog about it.

Now after raving about how good the series I’m watching is, I must say that it’s really hard to find good anime on American TV. Most stations play garbage directed at kids, but once in a while, you’ll find the good show that is geared for adults. But unless you know what to look for, you won’t even have a clue it’s there.

There are many other reasons why I think (good) anime is worth watching. Namely, each show has it’s own signature art, music, and plot development. There are anime shows for any genre taste. I’m primarily into the ones with martial arts, but that’s quite a few of them. Like any other form of art, chances are you won’t like 99% of what’s out there; but when you find that 1% that you like, you’ll be addicted too.

Here are my favorites (most have been featured on [adult swim] on cartoon network at some point):

  • Cowboy Bebop – all time favorite. Only 26 episodes, and is so good that it has a cult-status.
  • Ghost in the Shell – slow, but great plot and not epic (it actually has an end)
  • Full Metal Alchemist – pretty childish, but I liked it.
  • FLCL – this one is just plain off the wall
  • Bleach – carefull… it’s epic
  • Naruto – also epic (this is what I’m watching now)
  • Trigun – yet another epic
  • Frisky Dingo – this is not what I consider anime, but it’s a cartoon with the most complex comedic story line of all time. I appreciate a good story line.

Suitcase Computer: Finished Again

IMG_2227.JPG

The last time I wrote about my suitcase computer (the one I started back in December), it wasn’t quite finished. As I had feared, the single slot-fan was not able to keep up with the heat. I thought about adding another slot-fan, however the first one was noisy and it would have been tough to fit a second one in. So I decided that my plans to leave the top of the case intact for the “clean” look were going to have to be scrapped in order to install 2 tried and true 80mm fans.

These axial fans turned out to be quieter than the radial slot fan, and push about 10x the air through the case. I had thought about just going with one 80mm fan, but decided that I didn’t want to spend another night after that installing yet another fan when the first wasn’t enough. With the addition of the second fan, I also added a second intake vent, and got 2 filter covers to take care of the dust.

IMG_2228.JPG

At the same time, I decided to install the ¼” audio jacks that would enable the live guitar effects processing that I originally wanted this machine for. I also bought a distribution block so that I could change around the connections internally if needed. There are a total of four ¼” jacks, two mono, and two stereo. The mono are also switched, and tied to the ring on the stereo jack. This gives 2 jacks for input and 2 for output, for two audio signals each. If I have a stereo signal, I can plug it into the stereo jack. If I have a mono signal, I can plug it into the mono jack, and it switches off the ring of the stereo, essentially turning the stereo plug into a mono plug. This means I can either use 1 stereo, or 2 mono cables for both input and output.

IMG_2229.JPG

On the inside, in order to wire the ¼” jacks to the sound card, I took a six foot 1/8″ stereo extender and cut it in half. I then wired it to the other side of the distribution block, making it essentially an internal hard-wired patch bay. The 1/8″ plug simply plugs into whatever sound card port I want to use. The only thing that I am still missing is a mic input for when I play games online. While writing this, I came up with a great way to remedy that. Next chance I get, I’ll simply wire another 1/8″ plug to the input (which is on line in at the moment) which will send the signal to both the line in and mic in on the sound card. This will enable me to select which one to use in software without having to manually open and swap plugs, or install another jack on the case for just a mic.

IMG_2230.JPG

With the computer now 99.99% complete (I never know when I’ll want to add something to it) I am quite happy with how it turned out. It is a highly portable, power-packed, multi-purpose computer – exactly what I intended to make when I started. It serves up flawless 1080p HD video to my TV, plays the latest games, processes live music at high quality, and doesn’t sound like I have a hurricane in my living room. If I were to do this again, I would remove the video game requirement. I don’t play video games that often, and it really killed me on several issues. Without that requirement, I could have a super-low power, compact system that would give me all the HD and audio processing I need. Oh well, next time. For now, I’m calling this project a success. For real this time.
