I agree with you. I was originally a Math major and wanted to go into pure science, but I need a job and figured I'd go back to physics or math later maybe.

And it's not so much the applications that I hate, so much as the trouble shooting ad murphy's law.

But yeah, I agree with you, I'm the least engineer out of everyone in the class. I'm not dumb, I have a high GPA and people usually come to me for help on assignments and shit, it's just labs man. Too much stress.

>>3540

> it's just labs man. Too much stress.

Just wait until you get out into the real world where it's ALL "labs", only it's your career on the line instead of just a grade, and the actual work is being done by the lowest bidder contractor hiring unskilled labor, and you have to document the fuck out of everything to legally CYA for when some doofus with a hammer can't be arsed to follow a basic fastener schedule and you get a record snow load the following year.

And I'm serious about the documentation, only in the Real World you have to do it in a way that hammer monkeys and lawyers understand, not what engineering graders can understand like your lab notebook is.

>>3538

> I have a "hammer lab" which is a basic machining course,

Every engineering curriculum should include labs like this.

Unfortunately, most don't.

>>3543

Damn dude shut up you sound like an old person.

>>3545
He's right, a major portion of our grade on labs is documenting every measuring device and its operating parameters etc. if for example you don't document your calipers any table which references a measurement you made, as well as any calculations, graphs, etc. will not be graded as it is invalid. A forgotten reference like that can cost 20-40 points on a report depending on how much the error propagates.

They usually have government websites with this type of information. I don't see why an engineer would know this, we could tell you personal experience but not the general experience. You'd be better off asking schools, organizations that deal with statistics and related government sites.

>>3440
You are right: it is unlikely that many here would know it. It was a shot in the dark to post it.

The BLS does not keep track of data by graduation rate, and schools have been known to publish false data about employment placement. IEEE was also less than helpful.

I am simply not willing to take on the risks of obtaining a diploma (opportunity cost, tuition + student loan interest, resume gap) unless I have hard data that indicates a high probability of going directly from school to a high-paying position. Anecdotal evidence is insufficient.

>>3482

I saw a recent IEEE article that stated how engineering rate fared among the national employment and found that it could differ among specialties, chem E and EE were supposedly the lowest unemployment rate, but the others not too far behind. I think civil had the highest if I remember correctly.

If the money is the ONLY thing you like about it, you're probably better off going business some med.

I will say bioengineering and biotechnology seems to have been through the roof lately, so theres always that as well.

>what % of graduates go on to employment within their field after X months.
>I'm using this to do a few financial calculations
>I am simply not willing to take on the risks of obtaining a diploma (opportunity cost, tuition + student loan interest, resume gap) unless I have hard data that indicates a high probability of going directly from school to a high-paying position

That isn't a typical engineer's mindset... you sound like you'd do better in business/finance/economics or something like that.

For instance, I talked to a guy yesterday who was telling me about a solar panel system he designed and had installed at his house. He admitted to the fact that it was wildly expensive up front, and he won't break even on it (via energy saved + tax breaks and the such) for at least a decade. I said "that sucks" and his response was "Not really, I think it's kind of awesome. Plus, it was fun."... THAT, my friend, is an engineer's mindset.

>>3490

My concern is that if I get in over my head with student loans, they will come after my social security (for epilepsy, not some baloney like ADD). Given the current economic situation, I need to make sure that this is a financially prudent decision, and not the equivalent of swimming naked during high tide.

As for the issue of mindset - that sounds more like the mindset of a child i.e. judging things on the basis of 'awesome' and 'fun' than an engineer where a business environment is concerned. According to my father, the mindset of an engineer is one who takes knowledge of mathematics and science, and applies it to problems in business and industry. Because I have done well in both, and in the EE classes I took thus far, I do not see an issue of compatibility, but I do see one where finance is concerned.

>>3463

>Would it be possible...

I thought we were talking theoretical solutions here, on account of how retardedly out of OPs price range a project like this would be.

>Basically, quit being such an old man.

Hey, you're the one that wants to shoot at people instead of using a tech-fix.

>>3459
Then you'd need at least one more very large sound source, which would really piss off your neighbors.

Theoretically you could assemble a large number of sound sources into a beamforming phased array to help you focus your signal, but since this is sound we're talking about here it would be very difficult to implement ideally and much more likely to REALLY piss off your neighbors.

>>3481
Right, because saying it'd be easier obviously means I want OP to do it.

>>3479
What my point is, is that while you can get this to happen, it's so hard to get it even close to the level you're talking about here.

Even best case scenario, if the car was right outside a first floor apartment and you had a ridiculously powerful directional speaker (as directional as bass gets), and you knew the EXACT song, you'd be lucky to get 6dB of resonance on the speaker because there's so much more that goes into acoustics than that.

You've got the material the car is made out of, the directionality of the already off axis signal..

Your original post said "Would something like this be possible to construct?" and the answer is, no, not really.

>>3486
I'm not OP.

I think there is a way to construct such a machinery.

But not as a naive implementation as described.
What is needed is to project enough energy to overcome the speaker drivers damping at its resonant frequency.
A phase shifted signal would not accomplish this, but a system sampling the signal, determine the distance using duplex and predicting the driver position at the point where the generated wavefront hits it.
This is not particularly hard to do with highly repetitive music which has periodic occurring elements which sweep to below the resonant frequency of the driver. (The bass drums)

The problem will be projecting enough energy but something like a large plasma speaker could do it. (Just a big welding torch and some electrodes plus a parabolic reflector)

>>3508
Id rather work with someone who cheat his way through one class than some rat with the mentality of a degenerate bureaucrat. You seem to be jelly that he found a way to make his life a bit easier and you couldn't . Worry about yourself.

Seriously... I mean, don't get me wrong... what he is doing is wrong, you are right about that OP, but that doesn't make what you are planning on doing right. Think about it... do you think you're the only person that notices he's cheating? Why do you think no one else has ratted him out yet? I'll tell you why: No one likes a rat... period. I guarantee you that if you rat him out, you will do nothing but lose a little bit of the teacher's respect, and the respect of your peers if they find out too.

Hard work gets you ahead... not cheating, and not ratting. Just keep your head down, work hard, and you'll be rewarded for your hard work. You can't control others, only yourself, and I PROMISE you that being a rat is not any better than being a cheater. I am out of school and I work in the real world. We know who the rats are around the office, and they are not well liked to say the least. The rats don't get ahead any more than those they are ratting on...

You ever hear the saying "The squeaky wheel gets the grease"? It's not always true... sometimes the squeaky wheel gets removed and replaced with a new wheel that just doesn't squeak.

He'll get problems in time. Just wait

Don't listen to all these faggots OP. Tell on him.

Every year having a Bachelors in Engineering becomes more and more meaningless, and this is the sort of thing that makes it happen.

Think of it as whistle blowing.

>>3537
Think about it. Do you think you could've made it through college solely through cheating?

I know I couldn't. No way. I wouldn't even be able to get past first semester. In fact, most of the hard core cheaters dropped out first semester.

If they get a bachelors in engineering solely through cheating this guy deserves props and should probably be leading a team. Straight up.

I rarely cheat but when I do it's because I ran out of time and need technical info I don't have time to research on my own. Nothing wrong with that, I consider it teamwork lol.

>>3464
I would agree. Modern cars are as much an electronic device as a mechanical device. I am sure the demand for EEs has increased in the automotive world. But the total number of engineers in the automotive field is still pretty small, compared to the number of engineers across all specialties.

>electronic device as a mechanical device.

Mechatronics, whaaaaaaat

>>3464

Electricity might be what powers the car, but it is still a pure mechanical problem of translating that power into forward direction.

You might be thinking of control systems. That would be an electrical component controlling a mechanical one based off of input parameters (such as various performance sensors).

The electrical design of an electric engineer is one thing, the mechanical process of converting poward into forward motion is another, and using electrical sensors to monitor and control mechanical processes is another.

All three will always be relevant and no one more important then another.

>>3467

the number of automotive engineers isn't small, there simply aren't a lot of companies to work for compared to other industries

there are not that many car companies and car designs in a given year, enough for a good amount of choice, but about as much as the market would support

>>3202

>Is it true that most (mechanical/aerospace) engineers are dudebros ?

I'd say a huge portion of them are. It kinda annoys me, but I don't think its a good reason to avoid it.

When you get out in the field, depending on the workplace you might not have to deal with those types.

> Engineers should be more vocal when they know what their management is doing is wrong

Naw, son.

It doesn't matter how vocal engineers are.

MANAGEMENT DOESN'T LISTEN.

it's easy to point to situations like this as proof that management is always wrong, but if you consider the launch history leading up to the event....then it was relatively normal to the way things were operating (i.e. already pushing safety limits that they thought had high margins)

>They thought the naysayers might be operating on gut reaction, not science.

Right there is the important line. Normal operating procedures said things should be fine, they had no evidence to delay something so incredible expensive. Space flight is still a dangerous thing, many unknowns, etc...

It sucks that people died, but I don't mind playing devil's advocate in this scenario. It turned out to be the wrong call, but given the circumstances I think most would have made a similar call to proceed.

>>3533
Management is not always wrong. Quite often management gets things right.

But that is not the same thing as listening to the engineers.

>>3534

there's a limit that you have can listen to them and pay attention

on the one hand there is a "boy who cried wolf" situation going on, there is an engineer who can't express his concerns for various reasons (engineers aren't known for being forward and articulate), and then there is the general situations of the manager not being knowledge on a specific topic (acceptable considering the scope they oversee) and the severity of a problem

there are other factors, but it all combines into a stressful experience for everyone

>>3438
What you searched up and found sounds like a problem for manual transmissions. It sounds like the pump that actuates the gears is borked, or maybe the electrical connections?

I'm not too sure exactly what is the cause of your problems but I would honestly recommend bringing it to the shop. There is not much I won't try to fix on a car myself but an automatic transmission is one of them. I'll take one out and put one in but I'm not going to do any repairs to it.

> I know next to nothing about cars

Haynes sell a repair manual for the 95 Honda Accord, I suggest you buy one. In fact, you should buy the Haynes manual for any car you buy.

>>3526
Even with a Haynes or Chiltons manual, fixing most automatic transmissions require a lot of expensive tools. Unless OP plans on fixing a lot of transmissions, it's cheaper to have it professionally looked at.

Michigan Tech is top notch, They'll teach you how to do that an best of all, they have a mad scientists club there!

>>3497
I chuckled.

>>3502
Woah. I was thinking about going there for EE. How's the drug scene?

>>3502

fuck Michigan tech. Fucking cold shithole in the middle of nowhere

>>3529
Well it is about as far away from Detroit as you can get and still be Michigan Tech. Not being anywhere near Detroit has got to be worth something.

Or doesn't listen to their music on crappy ear buds.

I would choose:
6pcs 8x8 Led matrix
(40 pins needed in a 2x3 layout)
377 transistors and resistors for drivers.

There already is a FFT library so the only thing you'd be concerned with is performance. Mind you a AVR probably hasn't enough beef for a decent frame rate. But you never know till you try.

sorry meant BC337

Ironically small speakers like those in earbuds are particularly good at high frequency output. It's more like a function of age a teenager might hear upto 20khz in the 30s this is down to 12k or something, decaying further as you go.

Also those high frequencies are almost always overtones, midi notes go like upto 5khz and most music utilizes only 5 octaves so you are down even further.
3band eqs on mixers (like the one I have) have the cutoff at 12khz so any higher than that might not be needed.

I remember to tease my sister with a the ultrasonic remote of a old TV we had, so some people are more responsive to high frequencies, especially children.

>Complete layman looking for the no bullshit skinny on free energy and free energy engines.

Here's the skinny: They don't exist, and are impossible given what we know today about the laws of thermodynamics... Since physics is a constantly changing field, it's a very slim possibility that this won't always be the case, but as of right now, with what is commonly accepted in science today, they are impossible. Anyone who tells you any different is a crackpot. It's sci-fi romanticism at best, and flat out lies and fraud at worst. Granted, there are some amazing inventions out there that are extremely highly efficient, and CLOSE to perpetual motion... but they aren't truly over-unity devices, period. There's not a machine in the world that can indefinitely sustain its own operation (perpetual motion), let alone provide power for an external load (free energy).

This is a topic that will probably do better for you in /tinfoil/.

>>3491
^this

Please note, however, that there is a HUGE difference between the "free energy" crackpots and the "alternative energy" field. That's not to say there aren't crackpots in alternative energy too, but they are not ALL crackpots. Wind generators actually exist and work, they just aren't free.

There's no such thing as "free energy", but some energy sources cost a lot less than others in $/kWh.

>>3491
>>3492
While I agree with both of you on possibility of extracting extra energy from no energy, free$$ energy certainly is possible.

My uncle has a house that has electricity and everything but he doesn't pay shit for it. He's got solar panels and other crap that he doesn't even need to subscribe to the power company.

OP, if you ever want free$$ energy, the only way to go right now is solar and wind generators and crap like that. Look up 0 emission houses, they'll give you some ideas.

Technically speaking, bridging the energy meter is no-bullshit free energy.

It costs you 0$/kWh and it is proven to work.

>>3473

What DOES an IE do for a job? Why do you consider them lazy and greedy?

I honestly don't care that much about doing things outside of my job regarding engineering. I mean, I build my own computers and that's basically the extent of anything I do outside of school (which isn't hard, as you all know). I have a legitimate interest in physics (specifically mechanics) which is why I was interested in ME, with CE being a close second. But I'm also interested in Economics and I've always been very good at math, so I figured IE would fit me the best.

Basically, I'm really confused on what major I want to pursue and I want to make sure I make the right choice. I considered doing CPE too, because I'm a huge gamer and I think working for a gaming company as an engineer would be awesome. I'm not a great programmer though, so I don't know how well I'd do as a CPE.

TELL ME EVERYTHING ABOUT ANY ENGINEERING MAJOR, BASICALLY, /tesla/. In return, my eternal gratitude.

>>3474

There aren't many video game companies that need CPEs. CPEs can do a lot of coding AND hardware. Video games are almost entirely software.

Sure, you could become a video game programmer with a CPE, but you're going to have to take a lot of circuits classes you'll never use and most of your programming classes will be vague and not game programming specific.

If you really want to do games, maybe consider a school that specialized in that kind of programming. otherwise you're going to have to slog through a lot of shit that will have nothing to do with your job.

>>3475

Fair enough, that makes sense. Say I graduated with a CPE degree in hopes of getting a job at a video gaming company and couldn't find a job. Do most CPE grads get stuck in jobs fixing computers all day? What does the typical CPE end up doing?

>>3476

Ignore that, I talked to one of my good friends that knows a lot about CPE.

>>3472
Well nah, that was just my preconception, really :V

I rememebered tho that my friend said industrial engineering is like mechanical engineering, but it also studies the human factor in production. So, like a little more management oriented things. Which makes sense now, since engineering firms are always hiring management recently
