Miniature arduino controlled smoke generator

I'm looking to build a Miniature arduino controlled smoke generator for a static model of a B-17 Flying Fortress (so it has to be quite small).  I'm going to add stepper motors for the engines and start them in sequence, have Wav files for the start up and running, lights etc but I'm also looking to create the gout of smoke that is generated at start up. Any pointers in the right direction would be appreciated, it has to be controllable so that it can be timed for each of the engines. I was looking at the something like the smoke generators on the model railroads but wasn't sure how they work. Thanks in advance.

How can I get a ventilator to suck air from a smoke machine and trap the smoke?

 Hi, I`m making a 2meter laser etched cardboard dinamic sculpture face of a girl inhaling smoke with a smoke machine on the mouth, and I want to imitate this inhaling effect!:  2 Q> what can I use to get the "nose" to absorb the smoke? :  {"A fan or blower can be used to suck the vapor in. Then if you have a long enough duct or large enough chamber let the vapor evaporate/dissipate. You can also run it through a furnace filter to help condense the water vapor faster. "} https://www.rolight.nl/Home/Webshop/effect/rookmachine/EFNELOQ20/Look-viper-S-DMX-met-2liter-regular-fog I got the fog machine 2.1 Q> -I am looking for a strong fan or blower that sucks the air in like a nose (and some machine that traps the smoke particles coming from the smoke machine), but What am I looking for more specifically?

Smoke detector and ozone generators / air purifiers

I recently made a quite disturbing discover and thought I share it here so other are aware of it. We all love to protect ourself in case of a fire and the first and most vital of the information chain is a working smoke detector. In my house I had the old type installed, based on a radioactive isotope that detect smoke through ionisation. The newer types working optical or using combined optical and isonisation detection should perform better - but does not really matter for this "warning". If you do have pets, smoke in the house or just do a lot of cooking you might also use one of these fancy air purifiers that use Ozone to clean the air in your room. I only have a tiny unit for a fish tank that I also use to remove smells from my work clothes or purify some water for the plants. My discovery started with a simple cooking exercise involving a lot of onions, garlic and a big wok. To avoid filling the house for days with the smells I had the ozone generator running as well. At some stage I noticed that the whole kitchen was covered in the fumes from the cooking, nicely visible from the hallway - like fog. To my surprise the smoke detector did not the usual alarm but performed fine with the test button. So I blew some cigarette smoke directly at it - still no reaction. Next day I started to investigate and was prepared to buy a new detector but whatever I used, smoke, steam or just killing a burning candle underneath cause the alarm to go off. Then it hit me: The ozone! A quick test with the hose of the ozone generator next to the smoke detector and no matter what I blew in it the device staed silent. Ozone is ionized oxygen, the detector uses the ionized particels from the radioactive material to detect smoke. Smoke or very fine dust / steam will bind the ionized particles forcing the electronics to sound an alarm because the sensor no longer detects the ionized particles. With enough ozone entering the detector there will be always enough ionization to prevent the alarm. Conclusion: If you do use ozone in your house upgrade your smoke detector to a model that uses optical AND ionisation detection! Otherwise there is a good chance that the device is unable to detect a fire. Of course chance are slim that you would use the ozone while sleeping and a fire starts, but if it does....

Wood gasifiers and safety - Carbon Monoxide poisoning - hospital

Sorry if it is in the wrong section of the forum. If it can be moved to a better place then do so. This is a quick mention to anyone that is playing around with any burners such as:    wood gas generator    bio-gas    wood gasifier    'hobo' stove I am not severely concerned but it did happen, I think it needs a mention, as it is for everyone's safety. After playing with wood gas and attempting methanol creation from a small gasifier unit for a few weeks, I had started to realize that each day I had a most annoying headache / migrane in my frontal area of my brain / head. They ended up getting so bad that my body could not tolerate them anymore and started to go into shock, causing a rather painful, endless throwing up session for many hours each time even.  It came to a point where after 3 weeks of playing with a bio-gas generator for about 4 hours a day had started to lead me into temporary blindness an hour and a half at a time. This was when I was concerned as I could not read any more instructables :( After a quick jot to the local doctors, I explained what I had been up to and I was correct. I had given myself the rather classic, and very close to death, carbon-monoxide poisoning where my doctor insisted I go to emergency at the hospital ( 2 hours away ) immediately and have someone else drive me. Pretty much equivalent to staying inside a garage with your car running for 5 hours, all the doors closed. I was very close to severe carbon monoxide poisoning and death.  At the hospital, blood was taken, analysed, and they had discovered large traces of C02 that they attempted to flush with some oxygen, but this only works to a point and they mentioned that nothing else could be done apart from telling me not to use or be near any smoke sources for at least 3 weeks and I should recover fine. I am still playing with my wood gas generators, and attempting to make methanol, but these days, after 3 days ago, I take further safety precautions to make sure it wont happen again. Such as: ventilation / exhaust fan ( I WAS OUTSIDE WHEN I WAS POISONED! DONT TAKE THIS LIGHTLY! ) keep a distance, find a better way to ignite / extinguish the burner keep your face and body out of the smoke dont watch the flames / smoke from above for any longer than 2 seconds do not taunt the Criosote by-product of wood. I am not sure which is more toxic. The smoke or this.   ( criosote / bio-crude, whatever you want to call it, it is the condensate of the burner unit containing more chemicals, very stinky) do not store criosote indoors withough a sealable container ( the smell likes to soak into things, like my kitchen ) if you know what you are doing, keep oxygen tank nearby use all protective clothing and masks, etc. There was a small arrogance in my head when playing with these units. And that is simply that I was thinking 'it is just smoke'. Wood gas generators are generating a much more toxic smoke than just sitting around your camping fire and should not be considered to be something to play with, without proper valves, pipes, burn off points etc. It contains on some scale: carbon-monoxide, methane, acids ( acetic ), tar and many other defects that will cause you issues if you are not careful. Keep it safe guys, this was a rather difficult one for explination, but I do not want someone other than me to be in that same sickness / position as I was with the poisoning, as it is the most painful experience I had yet had.  Worse than me hitting a tree head on at 80km/h. Worse than falling 2 stories off a cliff onto rocks. Worse than being hit by a car and thrown over it's windscreen. Worse than the feeling of an unsuccessful home made rocket launch. All of these above I have had happen to me, and the poisoning was by far the worst and I was scared more for my life than than any above accidents. It is not a very nice feeling, it is a deathly, sickly, useless feeling, blindness is not far away from death if found in this situation. Oxygen / fresh air is the only thing to help you if poisoned, even if in hospital. Keep it safe guys. If you want me to write up a full on poster on wood-gas / wood-heater safety I can or even just a propper write - up on general safety with this smoke and the wood gas units etc. Ask please and I will. Hospital staff will most likely give you 'items of interest' for instructables if you just ask them too. I have a heap of things from a stethoscope to vials to 'red dots' for homemade ECG machines. They tend to like crazies like me that make weird stuffs .. i hope ive gotten the point across anyway.

Smoking instructables?

So, would smoking related instructables be frowned upon? i was thinking about instructions on how to smoke/hide your smoking blend of choice, there will be no pictures of me smoking weed, since i don't smoke weed, i will include pictures of me smoking legal smoking blend (damiana), will people rate low just because? is it worth all the negative feedback?

High tech smoke signals

Daniel Schulze is an industrial design student in Berlin who is working on a sweet smoke machine. The plan is to have a 7x7 grid of holes that shoot little clouds of smoke into the air. The smoke comes from a fog machine and is shot up in the air with drivers. Check out the video below to see a test of one row. The full setup will be shown next week at DMY Berlin.

candle's black smoke deposit seems not to be electrically conductive

(This is the first topic of the "failed experiments" group.)I was wondering if the black smoke of the candles could be electrically conductive (carbon) when deposited as a layer over a piece of glass.After a quick and basic experimentation, it seems it is not.Here is how I proceeded :- I've put a piece of glass over the flame of a candle so a black smoke deposit appear on its surface.- I did so that it becomes opaque (if you want to try, be careful that the piece of glass may break because of the heat)- then, I used two crocodile clamps to make the contact (I've put a certain depth of aluminum foil between the claws of the clamp and the piece of glass)- then, I tried to measure the resistance with a multimeter, but the multimeter displayed no value at all.

What parts to salvage from detectors?

Hey all - at the place I manage I have 15 defective Kidde smoke detectors coming back - now obviously there's something wrong with them but it won't be every part that's garbage. It IS however a good opportunity to get some multiples of same parts.  SO - if this was you and they are in the garbage otherwise..which parts would you salvage?  I'm willing to invest  maybe 2 hours of desolder time.  Other than the resistors and the LEDs, i'm not as familiar with the components used on these boards. suggestions appreciated, This looks like the closest model: http://www.kiddecanada.com/utcfs/Templates/Pages/Template-53/0,8062,pageId%3D28537%26siteId%3D463,00.html

Homemade Smore Marshmallow Testers

Ok,Here's an idea for those of you who want to get into the kitchen this weekend and play around. Some of you may have seen my Ible on making marshmallows.So here's the experiment. The favorite marshmallow treat for many people would have to be the s'mores made over a campfire. Lets see if we can recreate some of these flavors in a single marshmallow treat.Ideas:-Use the standard vanilla marshmallow recipe as a base.-Experiment with liquid smoke flavoring to add some smoky taste. Probably not too much.-Possibly add a bit of burnt sugar. Might be able to do this torching the outside of the marshmallow or by some other means.-Graham crackers. Either crushed into a powder and added to the powder coating, or left whole and just stuck to the marshmallow.-Chocolate. Could be added in multiple places. Could be added directly to the marshmallow itself. Cocoa powder could be added to the powder mix. Melted chocolate could be drizzled over the marshmallow or dipped in.Anyone else have any other idea or feel up to the challenge of testing out the recipe?

How could i produce fake steam/smoke effects for a steampunk costume?

I am in the process of making a steampunk/mech themed costume for an upcoming comicon. As the centerpiece for the costume i am trying to make a literal chimney tophat which i would like to emit steam or smoke or something similar in appearance from its open top. I need some kind of gadget or means to produce the desired effect that can be fixed inside the body of the hat. It needs to work in a safe manner and be compact and lightweight enough to wear inside the cylindrical part of the chimney hat just above my head. As a back up, in case i cant find a solution to the above problem in time, im intending to hack a bubble gun and use that for a stream of bubbles but i would prefer to have a means of producing a relatively convincing stream of fake steam/smoke. Any ideas are appreciated thanks... P.S. im not sure if this should be posted here or perhaps in 'science' so apologies if i posted in the wrong area

How to Re-route 9 Volt Batterie from Smoke Detector

Hello, We have 14 feet high ceilings and smoke detectors in 4 rooms at that height. Not wanting to crawl up the ladder to switch the 9 Volt batteries, one would think you could simplify this task. Use a 9 volt battery connector to connect to the battery ports in the smoke detectors, a wire each to a central point in the house, such as a hall closet, where each wire ends in a 9 volt battery box. I can find various 9 volt battery connectors to purchase, have umpteen yards of low voltage wire (from sprinkler system installation). What I don't know is, is there a limitation on the length of wire I can have a 9 volt battery on one end, and the smoke detector on the other end? Thank you. Stefan

All of them have slightly to widely different numbers, some Motorola, a philips, etc.  The main question I have is what type of chips are these as far as function goes? I tried looking these up but so far nothing absolute. Some numbers I remember are 8506, 8605, 8502; other numbers are way different and I don't remember what they are.

Using CO2 for a Jetpack blast off smoke prop?

Hey Guys! I'm making a jetpack for this upcoming Halloween. It's going to have lots of moving parts and cool stuff using an arduino, but the most important feature I want is a thick blast off smoke effect. I have been looking online, and it appears to me that a CO2 fire extinguisher would be great. However, these are expensive and not easily modified to be electronically triggered. I've considered a paintball CO2 can and a Sodastream. Will either of these give me the effect I desire, and is this plausible? I'd like the smoke to be at least as thick as the stock photo I attached, hopefully thicker and stronger. Thanks! I'll be sure to post pictures when I finish.

Asking parents for tobacco pipe, help please

Dear Instructables community,      I am 16, closer to 17 and for some reason i find nostalgia in pipe smoking. I have never known any pipe smokers but most people in my family have smoked at one time to another. I am wondering if i should ask my parents if  i can smoke a tobacco pipe or just wait in silence till i am 18 and buy it regardless of their opinion. For all those who are going to try to warn me to the risks of tobacco i know. It is proven that pipe smokers also live 2 years longer on average by the surgeon general. Also it would be legal because i spend my summers in Massachusetts where tobacco can be gifted by parents or guardian. None of my friends smoke pipes, i don't think its very popular in my age group at all i want to do it for me, why i am not sure.                                                                                                                     Thankyou

Food Smoker

I'm trying to make a home-made smoker, a portable one that is. My current idea involves using a wooden smoke box, untreated wood (Any suggestions on what type to use?) and a portable gas stove, like those camping ones. My first question is, what type of wood would be good to make the box out of? Any major no-nos as to certain woods? Second, would a portable camping stove (either methylated spirits powered or gas powered) heat a metal plate hot enough to get the wood smoking?

Dirt Cheap Acoustic Guitar Pickup

Hi I am concerned about the health and safety aspects of the instructable of "Dirt Cheap Acoustic Guitar Pickup by Xuthal". The project encourages people to take apart a smoke detector to obtain a piezo sounder. However no warning at all is given by the author that there may be radioactive material in the device, or how to recognise it and how to deal with it. I tried to post a warning on the article but for some reason it hasn't worked. I could not see how to flag up the item so I am posting here. Whilst the manufacturers of smoke alarms play down the dangers of Americium 241 dioxide (the radioactive material), they would most certainly not condone opening up a smoke detector sensor. Am O2 will most likely pass straight through the gut due to its insolubility, so your readers are probably safe from ingesting it. However, if the source is fractured into dust particles, it could be inhaled and will lodge in the lung for a long time. Being an alpha emitter the Am241 will very likely end up causing a lung cancer. I think this instructable is highly irresponsible and should be removed. In any case the item taken from the smoke detector, a piezo transducer, is readily available from any hobby electronics supplier and costs less than the battery to power the detector in the first place!

Birds use cigs to kill bugs - Crow week!

ODDBALL birds are surprising British experts by using smouldering cigarette to kill parasites on their wings.The rooks are swooping on to the tracks at a Devon railway station and placing their wings over the smoke to fumigate them.Commuter Jeff Jones said told Britain's The Telegraph: "I noticed the rooks because they are not usually found in towns. They were generally flapping about when a chap flicked a cigarette butt on to the track."It was still all right and one of the rooks swooped down and picked up the butt with its beak. It then flew around and landed on the platform, dancing around with this smoking cigarette in its beak."It looked quite comical. But then it dropped the butt on the platform and pulled its wings over it, collecting the smoke. It seemed as if it were using the smoke to rid itself of perhaps ants or something similar."Five minutes later another rook, or perhaps the same one, swooped in when another cigarette was flicked away and repeated the whole thing."Royal Society for the Protection of Birds spokesman Richard Archer said the birds must have learned cigarettes can be used to kill parasites."You have to be careful attributing behaviour but it would seem fumigation is the most likely conclusion. Rooks are very intelligent," he said.It's crow week on Instructables! Post as many forum topics about crows as you can! Main image from [http://en.wikipedia.org/wiki/Rook_(bird) Wikipedia].

black powder charcoal

I'm making charcoal for BP using macadamia wood in a tin on a BBQ fire. The smoke is PISSING out the 1/4" hole i made in the lid but won't ignite. Any ideas/suggestions welcome.

Ideas for making a ciggerete Case??

You put your pack of smokes in your pocket, and forget about them, leaving them in all day, and being a active person I am, I'm outside doing things, lifting shit, all that goodness. So by the end of the day, my pack is completely mangled and I'm lucky the smokes aren't all smushed up. So I was wondering, what could I make a metal case for them out of, I don't like the cheapy ones you buy in the store, I have a few empty hd cases, perhaps they could pose for some heavy duty cases if they were sized down a bit?
