What do you all, engineers, think of this? I think it will change the way we process / evolve in humanity. I think it will enable us to do things we can't now, like master quantum computing, and allow shows like Gundam to become reality.

What about you?

Until they come up with a mass production process it might as well not happen.

Almost all nanotech research is done with one by one mechanical placement of nanoscopic components. Lithographic processes create structures across a whole area at once which is a two dimensional process. The "pick and place" technique done by researchers to create single transistors is essentially zero dimensional (a single point at once).

Also Moore's Law is commonly misrepresented. Moore's Law says nothing about transistor speed, feature size or power consumption. Those just used to be a consequence of the same progress.
Moore's Law regards the price of a single transistor. That used to get cheaper because transistors got smaller and chip area is a major cost factor.
That however is not the only one, if transistors can't get much smaller the price of a transistor can also get cheaper if the chip area costs less.
So far semiconductor plants haven't focused on that aspect because it' was more efficient to focus on reducing the feature size, but nothing prevents them to focus on other aspects.

The only thing that could really revolutionize computing to that extent nanotech is made out to be is Drexler style molecular machines. That is however heavily disputed and is often viewed as crank science. See the Drexler Smalley Debate regarding the sticky finger problem and fat finger problem.

The one avenue that might lead to progress in a reasonable time-frame is DNA computing. Basically to use natural nanotech to our advantage or to bootstrap a nanotech production using ribosomes, DNA, RNA.

Homemade Air Tank/Bottle thing?? by Oliver Sockleluck - Sat, 15 Aug 2015 09:36:31 EST ID:cymD6AGd No.6773 Ignore Report Reply Quick Reply

What's the best way, or maybe, what are some different ways I can make my own air tanks that I can fill up with my bicycle pump? I'm thinking starting from the strength of a plastic soda bottle and working up from there. I'm all about building and powering my own stuff on my own. Apart from buying things I can't build (like a soda bottle and a bike pump) I don't like the idea of buying cartridges of CO2, or using electricity to power things. The more hand-powered/charged things I have, the more control I feel like I have.
You feel me?

In School I had to weld together steel sheets and a threaded pipe to make a pressurized tank. It should had to withstand at least 10 bar (145psi). The thing is myself and half of the class failed.
The one the prof made withstood 30 bar ( 435psi ) with ease.

You welded two long sheets together 4 times, at a 90 deg angle. Then stood them upright and welded vertically. Weld on the bottom ant top with the with the pipe. Mine leaked at the top where the pipe was attached which was impossible to fix.

chemical engineers, why do you suck?

To be specific, why do old chemical engineers suck? Why are you such dicks?

I'm an eletrical engineer that has been hired as a process engineer. Every fucking dickhead up here was a chemical engineer. I get so fucking tired of the whole lot of you. I have so much shit to do and your 50 year old chemical engineer ass walks in my office and asks about a number from 3 months ago. When I'm not able to spit out just what you want, you look down your fucking bird nose at me like a dog that shit in the middle of the room.

Dipshit I have better things to do. I have a lot of things to do. Every time there is a fucking study for anything, who gets the data? Me. Who gets the drawings? Me. Every time you want to cut back or change a process? Me. Anytime a PI page needs made or changed, me.

Maybe if you're so fucking smart you'd already know where this flow is leaving the second effect of our evaporator chain was and not need to ask me and then look disappointed when I say I have to look it up.

And you're the only group that has to be difficult. Anyone else is more than happy to wait. Everyone else is pleased as punch that I can make all kinds of PI pages, programs, excel calculators, lab experiments, etc, to make their lives better. Not you, fuckwad. You need the world now.

So... You're essentially the engineering equivalent of a secretary and your organisation and memory is lacking... then you get flustered when people are irritated that it takes you a while to do your job, when the people asking you these questions know that they could easily do these things if they were spending the same amount of time doing it.

Maybe if you didn't rely so much on your sheets and more on your memory, you would be faster at remembering things, and they would be less annoyed.

Sup /telsa/, would like some input from you

I'm finishing my bachelor in Aerospace soon and I doubting whether I should stick to Ae. for my Master or head over to Mechanical Eng. The only thing that peaks my interest now is Space Eng. as all other fun masters are full (leaving aerodynamic, structural analysis and something about logistics). Space Eng. is however very abstract for me and I don't think I'll enjoy it.

On the other hand I have Biomechanical/BioRobotics or whatever you want to call it, which seems quite interesting, but I don't know for sure, since I didn't do the bachelor (very similar though).

Would there be any reasons to stay at Aerospace (in terms of the master)?

I did conveniently do an Electronics minor during my bachelor.
I do find the logic thinking behind it fun (behavior in terms of state machines etc.) but not the IRL behaviour (amps/voltage/phases/poles/gain etc), so that's ok.

I just am a bit unsure if I'm leaving anything interesting/fun behind at Aerospace..

How is a degree full? Do you have to stay at your current school? Pick the degree, and then decide the school. There is way too much riding on that decision to let an arbitrary quota at one school be the main factor. (If you are returning to your bachelor's school, use connections in your departments to get into your desired program. It may take some work, but there's no reason to take 'no' for an answer there).

At the Master's level (and much more so the PhD level, but still important here), the exact subject matter you learn will vary greatly depending on the school you attend, and more so, the professor you work under. You might specialize in a highly theoretical field, but work under a professor who does a lot of experimental work (or the opposite).

You demand higher pay for your work, if working as a wage slave. The faster people would in theory get the more competitive jobs, stealing business from the competition on time sensitive jobs. World ain't managed right though, so comes down to luck, charisma, being liked, and managing to get the jobs done just ahead of deadline, regardless of talent.

Now, if you're freelance, you work by the job. You tell them how much the project costs, they send you the down payment, and as soon as you finish you show them the proof of completion, which is NOT the actual files, just a printout that shows it is done. Once the check clears for the rest, you hand off the files. When doing it this way, being fast makes you money faster and gets you steady customers.

Just a word of advice, when going freelance, try not to bite off more than you can chew. It's hard to turn down work when you need the money, but anyone who pressures you into a job is a piece of shit that you should not work for anyhow. Remember that, it will save you a lot of trouble.

Question: Lasers can be fired into a fiber optic wire and travel through without disturbance, what if you were trying to produce heat with said laser at the end of the fiber optic wire? Would oneself be able to place say, a piece of ceramic to absorb the heat of the laser? Would the heat distribute itself fairly evenly?

Just had an idea for a project and am thinking out a prototype design. Help would be appreciated! More questions will follow as well haha

I would imagine a thorough Googling would get you what you want.
From what I've surmised, I think it would depend on the amount of heat the laser is producing. If it's super hot, the fiber optic material could melt. It won't matter too much what the material coating the fiber optic cable is. What matters is the angle of incident reflection and whatnot.

So I was thinking about buying a 3D printer, now that I have a bit of revenue to spend. I want to buy a delta printer for its taller build space, but I'm not sure it's even worth it to buy one at all. I thought it might be fun to produce a bunch of high quality cosplay stuff, which would otherwise take a lot of effort with pepakura, or whatever else, but I don't know what I would make with it other than that. I searched online for things like "Must have for 3D printing" or "Best 3D printed items" to convince myself that it would be worth the money, time and effort that a 3D printer kit requires, but my father brings up the point that I have no real need for one.
TL;DR -Convince me to buy a 3D printer.

Have you even attempted to make something by hand in the past several years, without immediately giving up? I honestly cannot figure out why, beyond cool factor, that these simple devices seem impressive to people. The vast majority of people who use them, either make something once or twice with it, that would had been faster to make by an unskilled hand than to prep the data file for the machine, or mass produce garbage that could had been ordered for cheaper and at higher quality from a factory.

You'd get better results commissioning a professional artist for your cosplay stuff, snf providing them with sketches and clear examples of what you want. Just make a craigslist post in the gigs section. If you're not a douche, it should be easier, cheaper, and give you far better results.

I just want something that can give me a higher, more accurate level of detail, as well as easier (if slower) construction of difficult-to-manufacture parts and pieces.

X_x higher level of detail does not come cheap with these machines. Unless you're spending as much as a new car, expect to do as much work as you did on the wooden knife, on every single part to touch it up, unless there's been a major breakthrough in the past six months of which I am unaware.

Did you find any maker/hacker spaces around, where you can get a peek at the equipment in person? They aren't the miracle machines people make them out to be.

No, actually I'm on vacation, but I'll have a look when I return. I'm in between jobs atm, so I'm still sorting that out. But there's a company that sells Cartesian and Delta printers that's HQ is like 15 minutes away from my house, so I don't have to pay for shipping, I can just drive down and pick it up. Even with $200-$500 printers, you can expect a decent level of detail, especially for something as large as cosplay pieces. Sanding is probably necessary, but apart from that, it should be ok. Case in point:


I personally think it looks AMAZING at the primer stage, but he must have used shitty paint or something, cuz I think it looks worse when it's completed.

Also, if you don't think this could be industry, people have historically gone to bath houses in many cultures for longer than we have existing records of it. People still pay to use such facilities, even as necessity. Shit, the shower is a bigger motivation for a lot of travelers to get a hotel room than for the bed.

So yeah, bathe me.
