Okay, so I have this video on YouTube titled The K'nexecutioner (twin gatling K'nex gun) [the link]It's the video that features my huge first model, and it has been up for a while and has gotten lots of views, comments, a solid 4.5 rating, etc.But this one comment keeps coming up constantly. Yeah. The people who, upon seeing my video, cannot help themselves and must one-up me or prove they're better by saying I have no life. Normally, I just delete these stupid flaming kids' posts and move on. But, this time I decided to try and humiliate one of the flamers, just for the heck of it. If anyone with a YouTube account wants to jump on in, do it tastefully and maturely.:FOR THE RECORD: - I am 21 years old - I have the whole *top floor* of my parents' house to myself - I live at home because the college I go to is 20 minutes away - I have had a sweet, lovely, awesome girlfriend who has for *two years so far* put up with my dorky K'nexisms

You know how something just occurs to you?In various places around the internet, I find people who choose to have a "difference in opinion" with me.I like to think I am quite well-educated, and with a decent vocabulary, so it is usually the other party that descends to out-right name-calling first.That doesn't bother me. In fact, sometimes it entertains me, as some of the insults can be quite surreal.My current favourite is from a poster on the BBC. He turned out to be, er, rather right wing, and eventually ended up declaring that I probably want to go and live in the Marxist Hell that is Sweden.I had to check - Sweden is actually a slightly right-of-centre, healthy, wealthy monarchy, with no particularly horrific crime rate.It turned out that the poster had found out that Sweden is about 85% non-religious or atheist (and climbing), and also has a fairly healthy immigrant population.The poster put this together with the ranting of a Norwegian blogger based in Belgium (?), and decided that Sweden is doomed until it rids itself of all the Muslim immigrant criminals. The poster was a complete loon, but I loved the insult.Anyhoo, to the rambling point; what insults have you been on the receiving end of that have been unintentionally entertaining?

Via PhysorgThis robot uses the same way humans walk, but actually falling forward. "PhD student Daan Hobbelen has demonstrated for the first time that a robot can be both energy-efficient and highly stable. His breakthrough came in inventing a suitable method for measuring the stability of the way people walk for the first time. This is remarkable, as â€˜falling forwardâ€™ is traditionally viewed as an unstable movement.To watch Flame in action click here (WMV, 5.25MB).Next he built a new robot with which he was able to demonstrate the improved performance: Flame. Flame contains seven motors, an organ of balance and various algorithms which ensure its high level of stability."Robots that can chase us flesh-bags down to power themselves are now one step (pardon the pun) closer. w00t!

Hey everybody, Ok so me and my friend built a rubens tube for our science project and fired ot up today. It was awesome! But, we have one problem. the flames keep getting blown out or are dying and we dont know why. Our tube is about 4 or 5 feet long and has holes every half inch (1/16th drill bit). we used latex sheets on both ends. the propane is a camping tank (small) and feeds the rubens tube through 2x 1/4 inch feeds spaced evenly apart. It may just be that we need to let the tube pressurize more. Our tube is 4 inches in diameter and is about 5 feet long. We let it pressurize for about 5 minutes. I think maybe somewhere along the lines of 7 minutes might do the trick, because when we went to light it, the initial flame height was very short. Has anyone else used the same setup we have?

Joho! i am making something similar to the "fireslinger" made by tetranite. The big difference is that mine w ill use short jolts of gasoline, that come from a perfume tester, so there will be short big flames, but i need something to ignite the small cloud of gasoline. the problem is, that it cant be a flame, or a torch, because it will be mounted on the wrist. so i will need a reliable ignition source, like a electric shock, the only problem with electricity i use, is that the sparks are too small to ignite everything, so i need bigger sparks, made by anything that will easily spark!

Alright fellow instructables, here's the lowdown: I'm currently attempting to build a hand-held flamethrower that you only need one hand to use, sort of like a pistol. However, when I was looking at a diagram for a regular Army flamethrower, I realized something: The fuel tanks on the flamethrower werent pressurized, and the fuel was pushed out using a pressurized tank that was fed into the fuel tanks. Now here's my question: Because I'm just trying to make a little hand-held that I DON'T need to shoot 50 feet, can I skip the pressure tanks and just jump to a commercial fuel source, like one of those miniature camper stove fuel tanks? Thanks Outdoors!

Gotta love this so-not-street-legal mod to a scooter that shoots 15-foot flames out the back. Just a push of the button and WHOOSH! The creator, Colin Furze, can even change the angle if he wanted to. Aside from being illegal to use the biggest downside is that the flames can come back at him if he isn't careful. Wheels on fire!

Synopsis: I'm a novice here. I'm trying to make a small electric tea light candle work from a solar landscape light to put a "flame" into a crappy 12" metal dragon sculpture for some yard art. My quandary: The solar light only runs off of one AA battery (1.2 - 1.5v). It appears to be using a 0116 IC? (I know nothing about these) to act as the Joule Thief to power the white LED that I assume is running around 3v. The tea light uses 4.5v (3 x 1.5v) and has a 47 Ohm resistor, a capacitor, and a chip to control the "flicker" of the light. The Help: Can anyone offer up some suggestions how I can properly get the flickering tea light to run from the 1AA solar unit? Could I do something like: 1. Remove white LED from solar light and check voltage 2. Replace resistor on tea light to accommodate voltage coming from Solar battery 3. Solder new wire from where the old white LED was on the solar light to the power leads on the tea light. Thanks for any thoughts, support, or reference.

Hey guys, I'm hoping somebody here can help me out. I'm a newbie when it comes to electronics and whatnot. I can read basic electronic schematics (I know symbols for resistors, LEDs, ground, etc). What I'm wanting to do is create some Halloween decorations for my niece and nephew and their friends, which is basically a hand held lantern that has flickering LED's behind frosted glass to give the appearance of a flickering candle. There are several nice instructables I've found here that cover LED flickering, but at most they're dealing with things I'm not really comfortable with (555 timers and other IC's, programmable chips that use hex coding, etc). The effect I'm looking for is a red LED that doesn't flash along with a orange and yellow LED that do flash to give the appearance of a flickering candle flame. I've found a few places that sell these kinds of kits, but I'd only prefer to buy them as a last resort. Since I'm building several of these lanterns by hand, it would really be easier if I could buy several parts (LED's, resistors, caps, etc) and put them all together myself to save money. As I understand it, you can vary the values of the caps and resistors to get not only varying times of flash, but also a fade in/out effect. I think using a 555 timer would probably be easiest to get random flash patterns for the yellow and orange LED's. I'm not opposed to using a 555 timer, it's just I've never used one before and it's been difficult looking at the instructables here that feature 2 LED's that flash or 40 LED's flashing and trying to figure out how I add a solid non-flashing LED into the mix. Would it be simplest to simply buy a flashing orange and yellow LED and then use a cap and resister of varying amounts attached to a battery along with the non-flashing red LED to achieve this affect? Or would it just be simpler to use a 555 timer with two regular LED's to make them flash, and then wire the red LED I don't want flashing outside of the timer's circuit (I guess parallel to it so it still runs off the same battery?). I had considered using 5mm LED, though I'm honestly not sure how bright these would be. I'm not wanting the room to light up like the ceiling light was turned on, but bright enough to definitely be noticeable. I'd also prefer to either run these off of a 9v battery for mobile use or wire up a 12v DC adapter to it for a more permanent solution. I've seen a few sites that offer "single flasher led" schematics, but again, I just don't know how to add another LED to that circuit to have two that flash at different intervals as well as how to add a third LED to it that WON'T flash. I've also seen people use the modified LED tea candles, but again, that is a single LED and I just don't know how to combine that with another (or 2+) LED's in a circuit so they all operate safely off of the same power source. If anybody could lay out the diagram for the three LED's (or if you think it would be brighter to use 2 of each of the 5mm LED's I want to flash for a total of 5 LED's) along with either the r/c circuit or the 555 timer circuit, I'd greatly appreciate it. Like I said before, I've scoured through all of the flashing LED tutorials here, and while they're all really great, there aren't really any that fit my needs and because I'm a novice with this, I don't know how to take the information that's given and apply it to my needs :(. Maybe I need layman's terms for the setup lol. I'm sorry if this is all long winded and a long read, I just wanted to supply as much info as I could to make sure I was (hopefully) understood fully :)

Hi !This morning, I was wondering what was the maximum temperature of the flame of a simple candle.So, this evening, despite the answer is on the internet, I made some quick and various experimentations of my own, mainly because there was nothing interesting at TV ...I put a wire of tin with a diameter of 1 millimetre over the flame and it liquefied immediately. So I immediately deduced the temperature of the flame was over 505oK ...Then, I tried with a wire of iron with a diameter of 1 millimetre, and it did not liquefied. So, I deduced the maximum temperature of the candle's flame was below 1811oK.Then, I tried with a very thin wire of enameled copper (thiner than a hair), the enamel vaporized in a flash and the copper wire quickly liquefied. I deduced the max temp of the flame was over 1357oK.This gave me a maximal temperature somewhere between 1357oK and 1811oK.Then, I tried with a thin wire of copper (0.2 millimitres), and it liquefied. But I also noticed that, sometimes, there was a green flame adding to the candle's flame.On the internet, they say that coppers flame are green. This would mean that my candle's flame is hot enough to vaporize my copper wire ? and, thus, that the maximal temperature of the candle flame is over 2835oK ?????If so, why can't it liquefy my 1 millimeters iron wire ?=o/

I got me a new laptop, and it looks pretty boring. So I drew flames on either side of the keypad on the empty spaces. However, it doesn't seem to be permanent. When I keep my palm or finger on it for a long time, the color fades away. Any help on how to get it to be permanent?

Hey everyone, this is my first post and i was wondering how i would spell out a message on the ground in flames for a special occasion. I saw this sort of thing in the movie Daredevil, i think... where the police officer threw a lit cigarette on the ground and it ignited "DAREDEVIL" in flames on the ground... i noticed it burned for a while as i was watching the movie, and i talked with some other people about it and they suggested it could be some sort of gel... any ideas?

Please read full post before making any comments. First of all yes, I know real flame throwers use napalm and compressed air to operate, but I don't want any crazy range and lethal power. I don't intend on using this thing in combat. I'm thinking something with a 4-5 foot flame, more if possible, (I don't think it would be with propane, but please, correct me if I'm wrong). I don't want a jet flame so I'm assuming I'll need to lower the pressure to get a more "violent" looking flame with the desired ranged. A "gas pump handle" for the flame control (sorry I don't know the proper term for that type of mechanism. it's not really a trigger. A lever valve?), or I might use a solenoid, not sure yet, Whatever would be more effective. Again, please give me any input your may have. The fuel source would be a large propane tank that I will have strapped to my back, I already have a design for that. If that seems too extreme I might do what this guy did and use a small tank with a reservoir, but with two tanks for more fuel. ( https://www.youtube.com/watch?v=ypIGeNdJbJ4 ) I'm undecided on whether I want electric ignition if anyone could give advice on that as well it would be appreciated. Anyone who has made something like this or knows what they are talking about please give me your input. Yes, I know this is a dangerous project and I take full responsibility should anything go wrong. This is a video showing the flamethrower that in the above video being used. It displays the kind of performance I am looking for, except I don't want it strapped to my wrists. https://www.youtube.com/watch?v=D5_ogU4Jzt4

Well, hello there, I'm trying to figure out how to use some small flexible gas tubing of some kind and a sparker to make a project that will make it look like a flame is shooting out of each finger and thumb. I'm also trying to figure out a way to control the sparker and the highth of each flame without using my hands as they'll have flames shooting from my fingertips. So any thoughts? Thanks, Daemon Ulf

I want to make a big torch that lasts a long time and is inexpensive. Does anybody have any ideas? I was thinking that I could use a coffee can for a container for the fuel and a big piece of cotton for the wick. I saw a pretty neat torch on this website but I don't think that it would last for hours.

If you could have a custom bass (or have one) what would it be like? If i had one, it would have the cutaway style of a Music man bongo, with tribunal flame bridge. the end of the body would have a sort of curved flying v style to it. The finish would be a sort of metallic blue and black flame. KIllswitch, and a couple of built in effects, couple gaine and tone knobs. 5 string, with the usual music man head. Maybe a bit different though, all thats just off the top of my head.

Say if I was to sell electronic objects invented by me or friends, that may or may to be functional or may or may not be artistic what are the laws/certification/inspections/flaming-hoops that I would have to clear first and what is that entire process like? Does anyone know? The FCC is one of them, and it pertains to whether your object will make planes fall out of the sky or turn off pacemakers dues to magnetic waves or unauthorized frequencies, correct? Who ensures that the objects won't catch on fire or melt into a caustic China Crisis goo? How you convince them of this? Who else do you want or need a rubber stamp from before you can sell your radio wave emitting blinky bug at the garage sale? Or your robo-fridge ("Is your fridge running? Better go catch it!") in your Etsy shop? What if it had a sim card? Any illumination on this would be invaluable!

I have a set of MRI scans of my knee. I make lamps and want to make a lamp shade out of these scans. A friend says, no - they will burst into flames. Another pal says, yes - go for it, get an old lampshade from Salvation Army, remove the cloth and clip the MRI scans to the wire armature. Oh, and if I make one, to be sure to use a low watt bulb. I think the scans are cool. But if they burst into flames, that would be bad. So - any idea how this could safely be done? Thanks.

Recently at school there was an assignment in which we had to do a survey of 20 people. The teacher came up with 10 Questions and we had to come up with 5. Seeing that many people liked fire or duct tape, i asked which is better, fire or duct tape? The typical answer was "that's an impossible question" or "flaming duct tape". So which is better fire or duct tape? ***UPDATE MAY 5, 2011*** ok so the score so far is duct tape 9, fire 4, and flaming duct tape 1. and ratings 2 c'mon people lets get some ratings.

Hi, i've been looking over Ruben's tube lately with great interest figuring it would be a perfect inclusion for my media center and was thinking it would be great for BBQs outdoors as a semi-permanent installation.. Here's what i'm thinking, a Ruben's Tube, mounted on a stone wall with a pyrex guard around the naked flame to reduce the effect of wind on the flames and to improve safety, with a metal housing surrounding the pipe. Would this be feasible? Safe? How long could i theoretically run this for at a time without it over-heating? Anything i need to consider before beginning the project? Thanks.

Hi all! New to the board... So I am going to be fire for Halloween to complement my boyfriend's firefighter costume. I will be wearing a lot of body paint, a shelf bra, a skirt, and I will be making cone-shaped Madonna-style nipple covers (maybe I will make them horn/flame shaped I havent decided), that will point upward. I will paint flames on them that will continue on to the rest of my chest in body paint. I need your help in deciding how to make these pointy nipple pieces. I think they will be about 2 inches in diameter and be about 5 inches long. I was thinking of making them out of Polymer Clay and attaching them with Spirit Gum. They will be painted with acrylic. I am not sure if this is the best option or if spirit gum will even hold them in place. Is there a gooey-er adhesive I could use and a different material to make the cones? I am also hoping to make 3-5 smaller cones to paint flames on and attach to my arms. Any ideas? Thanks!! I appreciate all the feedback.

Last night I dreamed of massive Earthly destruction by huge flaming rocks from the sky. It was really, really cool, but rather scary. Black sky, massive and multiple flaming rocks from above impacting with devastating effect (some distance away, but close enough to feel shock-waves). Not like the image, more real and hot-burning coals like (but that's the best I could manage to get for 2 mins of searching)If it happens soon it's a premonition?(I also dreamed that some landlord-bast's had been in while I was out and cleaned my place out of all the junk and important stuff like my furniture, PC etc and moved the stuff out of the shed into my lounge, but that was a completely separate scene and in daylight...)I was glad to wake up!

THE PROBLEM IS THAT WHILE I DO GET A CONSTANT FLAME, I DON'T GET A BIG ENOUGH FLAME (it melts metal but it takes ages to do so) does anyone know of a way how i could get more amps to speed up gas production or of any way i could get more preasure (+maybe my gas isn't pure enough because i use salt as an electrolyte, could that be it?)

A few years ago, I found a plastic pumpkin with a "faux flame" set up inside of it. I liked the idea of it and am trying to replicate it to make a few faux flame torches around my backyard for halloween this year. The idea is that there is a small 12v fan near the top of a tube. There two or three leds glued around the top of the tube. The fan blows a flame shaped piece of fabric up and the leds light it up to look like fire. (possible future instructable?) Unfortunately, I don't know much about circuits and the math of electricity. I found a small fan (12vdc .13a) and 2 red leds (2.6v). I hooked them up in parallel with a 12v 1amp wall wort coverter but nothing happens. I have done a little reading online and wonder about needing a resistor in front of the leds. I wanted to hook it up in parallel to get the fan to work at full speed to make the fabric really blow. From all the circuits I have seen online, this one seems really simple, if I knew what I was doing. Can anyone draw me up a simple diagram? What am I goofing up on here? Thanks! Matt
