/tesla/, meet my friend /dis/ by Nigel Beblingford - Thu, 12 Sep 2013 02:08:09 EST ID:tB60PQ7m No.5897 Ignore Report Reply Quick Reply

ITT: general manufacturing.

So, I was watching some youtube vids on what to do with my new MOT when I hear that high voltage ionizes 'oxygen and nitrogen into ozone and nitric oxide gases'. Chemistry is not my strong suit, so I started thinking that I found an easy way to create N2O. A few internets later, I found that this wasn't the case... but I did find something else.

>Ozone does not react with ammonium salts, but it oxidizes ammonia to ammonium nitrate:
> 2 NH3 + 4 O 3 → NH4NO3 + 4 O2 + H2O

>Nitrous oxide is most commonly prepared by careful heating of ammonium nitrate, which decomposes into nitrous oxide and water vapour.
> NH4NO3 (s) → 2 H2O (g) + N2O (g)

Therefore, Windex -> voltage -> laughing gas. Q.E.D.

/tesla/ chemists: is this a real thing? Moreso, is this ChemE territory safe enough for an EE?

1) windex isn't ammonia, or at best is 5% ammonia
2) you would have to create the ozone, then pipe it through the ammonia
3) then you have to purify and carefully heat the ammonium nitrate

All in all, a lot safer, cheaper, and better to just buy your own N2O

I'm planning to build my own house one day, and I am most certainly not going to go the way of wood framing. I'm planning on either using concrete block or having poured concrete walls, and a metal roof, similar to how a small store or shopping strip is built. I would very much like to learn how these buildings are constructed. I have this book in the picture, and it is a very helpful resource for understanding the systems present in a wood frame house. If I could just find it's steel and concete counterpart...

Can anybody point me towards some good resources on this subject?

What? Brick houses are only as warm if you put cavity-wall insulation in them, and seeing as most brick houses don't have cavity walls, this puts them at a disadvantage. You can always put in triple glazing and roof insulation of course.

To any civil engineers here. Is the civil engineering job market bad still? From my perspective it seems it isn't good, even after the upturn in the economy. I've been applying and applying and applying. I got my bachelor's in 2009 when everything was shit. After a year of nothing I decided to get my master's to put give myself something extra and to add depth to my understanding of structural and geotechnical.

I got my masters in 2012 and I'm still applying for jobs and nothing. I need money, badly. I apply not only to engineering jobs but also menial jobs (clerical, administrative, data entry, fast food, etc. etc.) and nothing. I've only gotten 4 interviews the past year and none panned out. Nobody will tell me why I wasn't a good candidate for the position I applied for except one person. It seems I put myself in a shit situation by trying to make myself more valuable. I can't seem to get menial jobs because I'm over qualified or they think I'm going to leave them right away because I'll get something better so why waste time on me (which is shit because I would be working with them for a long time because nobody will give me a job!) I can't get engineering jobs that I want because I don't have 10 years experience for an entry level position and usually those positions have dozens if not hundred's of applicants. I love math/science and applying them. I'm absolutely ethical and want to apply myself to something. I'm teaching myself programming and more autocad through online tutorials to try not to feel useless. I'm getting close to giving up and getting quite depressed.

Having similar trouble and I'm a EE. I got below a 3.00 so I'm a pretty hard sale for actual EE design.

I'm probably going to start lying for production and processing jobs. I've had some interviews for being an EE in a factory, and I think I fuck up the question about "would you like to do design in the future" I'm an EE, so of course I say yes. Then they inform me that they don't really do design work, etc.

Then no call back.

I'm pretty sure they're using that question to screen me out because they assume I'm going to leave as soon as I find a good design job.

Sometimes I really hate engineering. Not the work, but bullshit like that. Everyone talks about integrity in engineering, but what the shit am I suppose to say? Who the fuck goes into engineering so they can work in a factory? Who doesn't have a dream job past the shit they apply for out of school?

I got my masters in 2011. I worked for about a year at a part time (24h/wk at $12/hr) job before finding my current position (salaried at ~$60k/yr). My job right out of my degree came from a connection I made shortly before I graduated.

Every month past you earning your degree that you go unemployed, you become worth less and less to a potential employer. Your employability boost from being a recent graduate starts to run out after 4-6 months and completely evaporates 12-18 months from your graduation.

OP, are you searching for jobs nationally or locally? If you have a masters, you should search nationally (or even internationally, depending on where you live). Don't be afraid to leave wherever it is you live now to get that job you want.

This gave me an idea, maybe OP can claim to have read a bunch of books (which has probably happened by now) and show his interest in the field, and present that as a skillset for a job.

The thing is these pharm guys have to get jobs somewhere, and if making the drugs at your place is illegal, then they had to get a job to make them first, so they really can't expect OP to have samples or physical evidence (lol).

I'd say definitely track down someone that does the job you want, and find out more about how they got it.

I posted this over in /tech/, but this might be a better section for it.

The wife and I are moving to our first home in a few weeks. There are no existing coax outlets anywhere in the house, so I plan on doing the wiring myself. I contemplated having the cable company do it for us, but from what I understand, most of them will make external penetrations into any room that needs an outlet, and I don't really want them drilling a bunch of holes into our house lol. Also, in our living room, I'd like the outlet on an internal wall that they wouldn't be able to get to otherwise.

Anyway, the house is a balloon frame type house, so in wall wiring should be really easy. I'm planning on doing 4 home runs (3 bedrooms and the living room) to the attic or basement (haven't decided which yet), and just asking the cable company to bring the service in there so they only need to make 1 penetration.

I'm planning on using regular RG6/U dual shielded coax... Is this a bad idea? Is there any real reason I should use tri or quad shield for such simple in-house wiring?

I'm planning on splitting them as follows:
1 2 way splitter
1 3 way splitter

-3.5db to one of the bedrooms (my office) where I'll have the cable modem
-7db to the living room where we'll have the high def tv
-10.5db to the 2 remaining bedrooms, where I don't foresee ever installing HD boxes.

Would it be possible to build a device that can take the heat from the air and make electriity from it?
I read about a diode that emitted more energy than the electricity that was put in and it did it by cooling the air around it but i can't remember where i read it.

I am talking about regular air temperatures so it couldn't boil water and drive a turbine.

If heat from relativly low temperatures could be harnessed then there is energy everywhere to just take. Also if the heat from electrical devices could be put back into the device then it would need a very small input of energy. It would be good in many ways.

There is a device that takes the heat from air. it's called a wind turbine. wind is created by diffusion of hot and cold airs all around the world. the sun heats the hot air, and that air flows to cooler aired areas, creating a flow. Turbines take the momentum from that heated wind and turn that power into usable energy. thus cooling off the air it was taken from
