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.

I made a wooden butter knife yesterday, forged a wall hook with my friend the day before that, and I made this papercraft armor last summer. It's still got some details that need some work. (I got impatient and didn't do the bondo part, like that weeaboo noted in the comments)

(Also, they spelled my name wrong)

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.

Truth.

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:

Hi all. I am designing a "view camera" (and old fashioned bellows camera like from tarzan) and plan on making it out of cutouts of masonite. I have access to a laser cutter that should be able to cut it out effectively, but I need to provide instructions. I run Ubuntu, and downloaded qcad. am I on the right path?

So i went away to college to get a Mech Eng degree and shot myself in the foot by fucking around and getting low grades. My GPA was a 1.96 so I decided to transfer to community college to get my shit together. I want to go back to the college i was going to but I need to give them a reason to take me back. So I was wondering if you guys had any ideas on some sort of project i can work on to present to the readmission committee. I have time and the internet and library at my disposal so i should be able to study anything I need I think.

optimising and automating this would probaly be able to get rid of a lot of problems.

And also; not something to automate but this would really help the advance of sustainable power (I mean wind and solar, not biomass): Large scale, cost effective energy styorage. In my opinion this is holding back the sustainable tech the most at this point.

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.

Going into uni for EE quite soon, looking for resources to teach myself the very basics of electrical and electronics systems as well as computer science and anything else I might need to know. Basically I'm looking to learn, for now, all I can about the guts of the average house-hold electronic, enough where I can maintain general maintenance and maybe even get a little creative.

What else should I be studying like hell before I get into school that will prepare me, the basics of EE if you will?

You can look up those sites that teach you all about circuits to get a very basic background. Look at the books that universities are using (most have public facing class pages) and use those books to teach yourself as well as online videos. You'll be looking to learn in the EE department: physics, electrical circuits (using mostly passives except op amps), electronics (getting into transistors), signal integrity (if you want to mess with high frequency PCBs), and probably some other stuff I'm forgetting (which you should look at a university curriculum to fill in. On the CS side you need to start learning a language and in the case of embedded programming you'll want to focus on C and assembly (but don't worry too much on assembly yet unless you just want to do x86 and ARM). Get a good understanding of computer architecture and how to work boolean algebra and design things with gates (basic digital logic stuff). Move on to Verilog/VHDL and work with CPLDs and FPGAs if you want to get into custom ASIC work. Learn a real high level language like Python to help you make useful applications that don't need high performance.

fiber optics are already being used to transfer data but not every machine can be directly connected amirite?
so similar to wi-fi and such is it possible to utilize light in the same manner? like specific wavelengths transmitting to a device that would decode it as binary -

in a bigger scale - would it be possible to construct a massive device that could be thrown into space and transmit a binary.. like a star flickering - we're transmitting radio waves into space right?
would this not work? - also, though i don't know much about what i'm talking about
i think lasers would also be able to do the same, though it would take a precise calculation and such.. but say we sent a satellite somewhere like Saturn and fixed it with a device that would transmit the data back to a receiver with a laser transmission i'm sure it could be done...
just trying to think like aliens - i mean.. imagining that aliens are super far from each other and they have to communicate - light is the fastest known thing so.. i would think that transmitting data in this manner would be the best and fastest way...

Any electromagnetic wave travels through space at the same speed as light. So in terms of latency, light communication isn't any faster than normal radio communication that we use today. However, optical communication does provide way more bandwidth than radio. Because light has such a short wavelength, a lot more information can be crammed inside a given time frame.

Getting it to work over long distances is a challenge because it takes a lot of power to generate a light signal strong enough to be detected really far away, and the beam must be focussed at the receiver. Technology is starting to catch up to where we can use optical communication at further and further distances:

There's an interesting research paper about this put out by Disney (Yes, that Disney) about specifically this.
You see, an LED is not only an transmitter, but also a receiver, as there is a slight but still there change in resistance when it receives light input of specified bands, usually split by the plastic coating on it.
Hence you can image that if you were to adapt a device to receive and transmit using only one LED, then you could have two of these devices, and do an I2C style master slave transmission routine, that scales up to an arbitrary amount of devices.
I think they get like, 8kb per second over a tiny ass range, but it just werks though.

I hope this is the right board for this thread. Basically I forgot to put my electric bike battery into my car before driving off after a ride the other day and managed to reverse over it in a fit of idiocy, cracking the lower part where the battery connects with its cradle on the bike, as seen in the image. It worked intermittently afterwards, cutting out after bumps for a few seconds and otherwise working fine. Now I have opened it up and managed not to electrocute myself, I have discovered there are two loose wires and no other visible damage, which leads me to believe the whole thing can be salvaged (which is good as they are hideously expensive).

What I need to know from you guys is 1) Where does the loose red wire hanging down above the pack itself go? I think it might attach to the other side of the fuse but I am not sure

2) how should I attach the other red wire to the fuse (one with the coil)? What is the purpose of the coil? can I just solder it on?

Thanks in advance for your help, and my apologies for the triviality of this issue, I think my guesses are probably correct but I don't want to make any mistakes and ruin the whole battery.

Eh, I'd google for plans or repair guides for this specific model of battery.

That 'coil' looks like a crooked contact spring to me, (on the top of the picture)
From the looks of it the red wire on the bottom has been broken off next to it.

Before you proceed you'd have to know what wires are connected to what and how exactly the cells are wired. I hope you have a multimeter and know how to use it, right?

The other thing is, I wouldn't mess with a li-ion battery without knowing exactly what I'm doing. There are several things that can go dangerously wrong with them (They can pop release toxic gasses/explode/catch fire if handled incorrectly) And depending on how they are wired it's fairly easy to do something wrong.

I think you should look for a fellow e-bike enthusiast who also runs a shop in your area or try to meet up with somebody if that battery is so important.

Judging by the blob of solder on the loose red wire, I'd say it belongs up next to the red wire with the spring, where there is a terminal with a blob of broken solder.

I'm also guessing that is the fuse, so that would tell me that the terminal with the blob of broken solder is not supposed to be touching the red wire with the spring and needs to be bent away so that it does not touch.

Ideally that wire would be soldered in place but if that's not practical you might or might not get away with using a little bit of wire and some tape to tie it into place, remember you could cause a fire inside the battery and subsequent explosion if this connection is not secure and tight. Tight is right.

If that actually is the fuse up there I'd also check its not blown, if it is blown, try replacing it but resist the temptation to bypass it by touching the two red wires back together as it might be a sign the battery is actually fucked.

Also remember that I'm just a guy on the internet and if you try this repair yourself and my advice is wrong you could end up blowing up the battery, but no worries really since its already fucked anyway.. as long as your house doesn't burn down or something because of it.

so, assuming you want to actually make new cameras (ie a shutter system) make a simple security camera with an ardunio or make an older film camera. The quality will be laughably low but you'll learn a lot of important stuff. Also, how much experience do you have with a photo lab?

Senior in chemical engineering here. About to graduate with a 3.9.

I smoke weed every day. I drink at least four times a week (not counting a beer or two with dinner, which is a daily ritual for me). I do shrooms/LSD occasionally, whenever I have the opportunity to go somewhere cool with my friends to do it (I'm over tripping in my room). I go out/go to parties Thursdays, Fridays and Saturdays just about every week, and maybe some Tuesdays and Wednesdays depending on what's going on.

You can get all kinds of fucked up and still succeed as an engineer, as long as you learn to manage your time. If you do your work in the late afternoon/early evening, then you can drink, smoke pot and do whatever in the night. I've never had to pull an all nighter for school work.

Another big thing is go to class. Maybe you're still in the high school phase where everyone goes to every class, but as you go on in engineering, you'll see a lot of people who just don't show up. Most of my classes are usually about 50% full. People skip class, don't know what's going on, then get wrecked on exams, and act surprised. Just go to class.

Anyway, I hope you find some cool engineers to get stoned with.

Hey /tesla/

I recently took apart an old TORO weed whacker that hadn't run in like 12 years, and got it running...briefly. It started up for like 2 seconds, and shut down.
I figured out after pulling the cord a bunch of times that the engine was being flooded. This was indicated by fuel spitting out of the exhaust. So I sat and thought about it and disconnected the fuel intake line from the carburetor. Sure enough, after a few pulls on the cord, it started up and ran for a good 8 seconds with a few revs before it shut down. So it ran on magic.
So it's either getting too much fuel, or not enough air. Too much fuel I'm thinking.
I can't find anything on how to adjust an old ZAMA carburetor online though. They're all newer models. This one doesn't have the priming bulb.
Thoughts?
Cheers.

Okay, that didn't really work any better. All it did was make the fuel move through the line slower, which meant a bunch more pulls just to have it run for like 4 seconds. So, maybe it needs more air AND less fuel. Here are a couple images that resemble it. It's late and I don't feel like going down to the garage to get a better look for a model number on it. All the fuel is nice, and the spark is ferocious. I may just disassemble the carb again. Maybe the problem is the needle is too loose?
