Hey /tesla/

wondering if any of you guys could point me in the direction for further reading into engineering my own sound system..... or do think it is too ambitious to attempt such a feet as I have done nothing of this nature before??

Building your own speaker boxes would be fairly easy, but it's probably easier to just buy those, the amplifier will be enough work as it is.

depends on what exactly you want to do, if you just want to build speaker boxes for your sounds system then I reccomend you take the right speakers with them. everyone on the internet says it, though I have not ever seen an argument for or against it.
here are some sites for speaker building (the first two are in dutch but I fthink you`ll be smart enough to figure out the designs):

it can make a virtually inexhaustible supply of free compressed air

This system could eliminate the dependancy on oil (that's why it's so unheard of). It is the best form of renewable energy and badly needs development and publicity.

I'm doing a two year degree in electronic engineering and I wanted to know how I should be going about this. I'm 18 and doing well in college, but after I get my degree I don't think I'll know how to actually go about getting a job. Do you have any general advice on getting employed?

Should I study aboard?

I got in to study chemical engineering in Helsinki Uni. of Technology. I haven't been able to begin my studies yet due to military service and I'm currently thinking of doing my degree in another country. I have an international background and a ton of friends studying in USA, other Scandinavian countries and Britain.

I'm eligible to get a scholarship that would cover 75% of my tuition fees for both bachelor's and master's degree. I'd also get around 600€ a month of student benefits, would be able to a low interest student loan backed up by the government, and I have a good resume to get some minimum wage job at a store/hotel.

Would doing bachelor's in chemical/biomedical engineering in some country and doing the master's in another be a moronic idea or would it have the potential of being really fucking sweet?

Yes, but don't make the mistake I made and write a thesis at a company where you want to work later. Don't do it at a foreign university. You will get your degree but compared to your student friends back home you will have trouble finding a job because abroad you are disconnected.

This is why big companies have special seminars for expats who want to come back to re-integrate them back into society/company.

That mistake ruined my career. I studied biomedical engineering btw. Fuck that !!! There are only two real engineering disciplines: Electrical and mechanical if you don't want into sale.

Hey /tesla/

So I'm a Biomedical Engineer, but I don't particularly like the medical aspect of the major (hate it actually). I want to get my PhD in a somewhat unrelated field, something like physics or ECE. Am I foolish for thinking that I can cross over into a good program for graduate school? Grades and research experience won't be a problem.

Also, changing majors really isn't an option since I'm a 22 year old sophomore. I can't wait until I'm 30 to start my life...

What do you think?

My cal1 teacher who was one of the best I've ever had got his bachelors in BME, then got his masters in EE and went to design chips for TI. He became a project manager making ~90k+ at the age of 30, only reason he says he took up teaching was that he wanted to have more off time with his new kids and share knowledge.

U wot m8? A PhD is a 5+ year slog, for bugger-all money, with no certainty of getting a job outside of academia, and no certainty of getting one in academia too. If you want to work in industry, just get an MSc, and get some real world experience.

People do PhD's in barely related fields all the time. It's not a weird thing at all.

Of course, it is HARDER to get into a PhD program outside your major, but it's certainly not impossible.

That said, if you cross over, you may still have to go back to undergrad and do a few extra courses to prepare yourself early. Just go and check out the universities and grad progams your interested in. They should have sections on minimum requirements, recommended preparation, and the course list for their masters and phds.

That totally depends on your ambitions dude, a MsC and BEng aren't going to provide you with the tools that a PhD provides you.

This is especially true for the more theoretical subsets of engineering fields, especially Electrical Engineering.

If you're comfortable with working your average engineer job then go for it, if you want to be the first to discover and solve a particular problem, well then the choice is clear.

As a side note, I plan on going into graduate school in math, not engineering, so take what I say with a grain of salt.

So for those of you whose schools have summer semesters, holla. What are your schedules like?

I have:
Materials Science
Advanced Manufacturing
Electricity and Electronics
Calculus III

Pretty easy seeing as the classes are rather spread out through the week.

So, what about you? Hard semester or easy one?

I want it incorporate a mechanical suspension
That can lift up the cart for traveling
So it can go up steps and curbs

if i was building it id use something like this http://www.discount-trailers.com/images2/trailer-wheel-jack.jpg. id some how mount it slightly offcenter so when i came to a curb, id just raise the one side pull up, lower wheel and continue on you. id use bike wheels and make it at elbow level the entire time.

if you plan on going far and wide with this on a trailer, why not just convert a old UPS truck into a moving food bus. kinda like an ice cream truck

Depends on how much you want to learn, and how much you know already.
Use the NEETS - it's the US Navy Electricity and Electronics Training Series. That's what I'm using to learn E.E. right now. You can download them from here:

That would be my best recommendation, but might not be the best for you, depending on where you are, and where you're going! It's extremely in-depth and starts off with a 0 assumption of previous knowledge, and teaches more of the "how the components work" in the beginning than how they go together (which in my opinion, is the best place to start!)

In any case, best of luck to you!

You should start with a book on basic analog circuits complete with the math
Building and calculating on a radio kit is great way to learn the basics
Then move on to AC.

I find it spectacular that you can sign up for a course in designing power grids without any form of prior certificate.

ok so basically im asking besides a car battery with a inverter, one of those portable car battery chargers that double as wall outlets, or gas generator, do i have any other options?

i dont even know what to start googling for this, other then the three objects i listed.

A typical car battery would have about 1000 watt-hours at most, so if you are using 200 watts, you'll get 5 hours.

Pulling some ballpark figures out of my ass, a couple phone chargers would use like 5 watts, LED christmas lights would use 20, and a blacklight would use 50, for a total of 75 watts. 1000 watt-hours / 75 watts * 75% efficiency = 10 hours.
