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!

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?

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!

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

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?

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?

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?

I was going to make an instructable on mini roasting when something hit me. When you use the lighter to light maybe a marshmellow, is the fire or smoke or fumes from the fire toxic? I mean the gas/alcohol gets neutrilized when it burns up and turns into flame but If i cook with it, it may be a different question. If someone asks me to think about smokes, the I should say to you that smokes are already toxic and anyone smoking shouldn't care. ( I don't smoke, I want to live) If possible you can answer this question and have credit in my next instructable.

Hi Im working on a flamethrower which is turning out pretty well, the only issue is, since im using alcohol as the fuel, the flames are pretty much invisible, i was wondering what i could add to increase the carbon content. Normally ide experiment with adding a little gasoline, or diesel to it, but i have to be careful with my pump, its made from either ABS or PLA, and for some reason everyone on ebay who sells them are very sketchy, ive bought 4 in the past and only the last one ever arrived. Anyway, what can i add to my fuel to make its flame more visible? Fortunately my flamethrower does not leak at all so its safe to move up from alcohol to something with a higher burning temp. What can i add that will not dissolve the plastic, increase flame brightness, and not increase the burn temp too much. Before hydrocarbons, are there any salts or chemicals i can dissolve into the alcohol to do this? i beleive i can dilute the alcohol a bit with water so it will take sodium, but will that have any significant effect? The sun is pretty bright here so alcohol flames are invisible, gasoline flames however are very visible in contrast. Thanks

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!

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.

Question by liquidrive | last reply
Ok, I need a power supply for a solenoid. It is to simulate the kick of a pistol. I need a power supply that is small, so that I can hold it in my hand without being to heavy to hold for a long time or it being uncomfortable. The solenoid will have a neodymium rod made of lots of 6mm*3mm neodymium magnets inside it. The coil is 5cm long with 0.8mm ECW and 7 layers although it can be rebuilt. The point is that I need something to power this coil and let the neodymium magnets hit the wall behind the coil (wrapped around a 6mm tube) and produce a sort of kick. The power supply needs to run on a roughly small power such as two nine volt batteries (dc). This is a long question but I would greatly appreciate any help. Thanks :) (I have a circuit to make it produce recoil (electic bell...) but how will I power it to be powerful enough!?) Thanks again!

My bike is a standard mountain bike and I wanted to give it a more custom look than my paint job. I thought the best way to do this is to add a flamethrower to match my custom paint job which will be a red pinstripe around the flame, when the flame itself is grey. The flames will have skulls airbrushed in it. The rest of the body will be black with a little red pinstriping action. Maybe even some lettering reading : "Beast". probally with the same skull and red paint scheme. I want the flamethrower to fit in with everything else well, but I don't want to change the frame much, or paint the flamethrower.

Question by MissPennyFarthing | last reply
I have several lighters that I still like, either for their design or intended purpose. But over the years some failed to produce proper sparks with the piezo. For some I could salvage replacements from cheap lighters but not so much for the longer ones - the type to get your bbq or oven going. Here the wire from the igniter is in ne long piece going all the way from the piezo, through the long neck to the flame outlet. As the wires in those piezo igniters are aluminium it is next to impossible to attach a longer wire as usually there is no room for crimped connections and the isolation is a problem too. I also have one particular lighter that uses a slightly longer and thicker piezo igniter, the common ones don't work here as they are too short. Adding more support underneath is a no go as the shorter ones have less travel when activated. Last but not least is one lighter that requires a piezo with not just the little metal cap at the end but with a full metal body for the stationary part. The lighter in question does not work with standard types even if I add a little metal strip to make proper contact. Problem is simply put that like this the standard ones arch over and no spark comes out of the wire. So big question: Is there any supplier or Ebay shop where one could actuall see the various types of piezo igniters and order them in small or single quantities? So far I already struggled to find a source for the crappy standard ones and the only one I found wanted to charge $ 2.95 US per igniter plus postage. Sounded a bit greedy to me considering I can buy a complete lighter with it for around one single buck...
Question by Downunder35m | last reply
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/

Got some simple prototypes working for the gas creation but do struggle a bit with converting some orifices (is that eve a word?) and a torch to work with hydrogen. Not to mention the pressure regulation LOL Biggest problem so far seems to be the flame temperature. The gas is produce at up to 50°C and my current burners all start to glow red hot after just a short amount of time. Where they struggle to braze copper with propane the hydrogen is almost overkill ROFL Must be really close to these yellow acetylen bottles the plumber use. So big questions: Do I really need a different orifice hole and if so bigger or smaller than used for propane/butane? Do I really need a acetylene rated torch or can I just ignore the orange red color of mine when using hydrogen? I don't think it will melt but after a while the heat travels down into the handpiece too...
