I wan't to fill a chamber with hydrogen, have a chamber of the same size linked with it, with a heavy visible gas in it, then as I pump out the hydrogen the heavy gas displaces it and I can see when I need to stop pumping and refill with hydrogen. What gas can I use, I know just about any visible gas will work because hydrogen is the lightest, but it would be nice if it was heavier than average air so I could allow air to flow into my heavy gas chamber to displace it. Or can I just die the air with some kind of smoke from my smoke machine. Yes hydrogen is extremely explosive, so this would be on a very, very small scale with hopefully 0 oxygen.

Hey Guys. I have a laser tag project that I am making. Now I want to put high pressure air recoil on it. With the HPA being in the magazine and the recoil being a blow back valve in the gun. The issue I have ATM is the connection between the gun and the magazine. I basically want it like a butane connection. I can't find anywhere that shows designs or standards for this though. Or anyone who sells these parts. Also I don't want to use a gas magazine as I have custom magazines and guns. Cheers.

I was thinking of taking a weed whacker and taking the pole off, taking the motor, put it on a chain drive system to the back wheel. I have two questions about this. First, will the motor have enough torque to pull a 130 lb. guy, and is there a transmission system I have to over come.

Hey guys and girls, I am after a supplier for gas inlet valves, or a standard or anything... Basically I have a laser tag system that I want to add high pressure air recoil to, but I want the air supply in a removable magazine, that will then connect to the gun and go through a blow back valve once the trigger is pulled etc. Now, the problem I have is the connection between the magazine and the gun, to allow the gas to flow through, I know airsoft guns have recoil magazines that they can use, (Im in Australia, so i don't have access to these). But would really like to know where I can get some of the parts from. Or designs maybe.

We are making an arduino-based gas detector that uses a combination of LED lights and a beeping piezo element to alert users to different levels of carbon monoxide in the air. We are having some difficulty in coding to have all the elements work together properly. What are some examples of arduino coding that can have a gas sensor chip, LEDs, and a piezo working together with a set of triggers, like the different concentrations of gas?

Hey guys, this is my first time on the forum section of the instructables! Not a bad place to be, really. So here's the thing. I have this old scooter that I've had for as long as I can remember. It was the very first thing I rode that was powered by a motor and my father bought it for me so I could get ready for my first motorcycle (Which was sadly stolen about a year ago :/). Last year, my dad went back to our hometown to visit family and he brought it back with him, but there was one problem. We have no gas tank for it. I have NO idea where it could have gone or why it wasn't brought back. Oh well though. I have this scooter, the same as Wesley666 does. I'm having trouble finding the gas tank on my own. Notice that there is a gas tank that I took from a weed eater just to try it out. But I'm not sure it would work out very well. I mean, look at the size comparison between the two? I also want to keep original parts on this nostalgic machine. Sorry if the pictures are oriented weird, but these are taken with my phone.You can see from the thread posted above there is a picture that shows a blurry close up to the gas tank and I can't really tell what it says. "Something EBR Motor". Long story short I need to get that gas tank, maybe even the gas line that comes with it, in order to get this thing working again. Does anyone know of the brand name of the scooter so I could get the original parts I need?

I want to store hydrogen gas(not browns gas) in some kind of pressure container. Since the propane tank is not a good idea from your forum, I was thinking about using a truck tire that could be pressurized to 120 psi. What are the hazards in this process. I would suck out the air from the tube tire with a vacuum pump and then generate hydrogen gas, compress it into the tire. Will it work or will it become unstable and blow up?.

Available pluses home gas generators: * Rate per se gas generator compared with the price affordable euro GASOLINE. * The price of fuel is lower than that of the generator on diesel or gasoline. Available Cons: * Gas ââis considered the most volatile than diesel or gasoline. * Appeal from the gas and the installation of equipment for gas processing requests for special and separate permission. Our legislation prohibited the installation of systems and gas processing equipment in the absence of a suitable plan or agreement. * Most of all, on our market, there are gas generators made in China. * Gas ââgenerators are made on the basis of a gasoline engine, the method of adjustment of fuel injection system and fuel carburation. In accordance with this resource from the generator corresponds to the resource gasoline engine. * Later, the acquisition of the gas generator of small capacity, the buyer is faced with a specific limitation on work: a maximum of 6 hours per day. The resource identified by the manufacturers of gas generators, with the first glance quite broad. However, do not understand the root cause of its increase. On average, the share of gasoline engine, out of which gas engines, floats in the range up to 2000 HOURS. This common resource for the euro generator. Imagine the Chinese gasoline engine, the resource is constant. Next, suppose that the resource oposlya changing gasoline engine to natural gas will not decrease. (Our real change of cars with fuel gas indicates a reduction of the resource engine, which originally was made for 1-octane gasoline, well, and subsequently applied for another). 1 of firms offering gas generators, a guarantee in 2000, machine hours, or one year, although with the limitation, at least 6 hours per day. The appointment of such a generator is not clear. As a source of constant power, he will not do, as backup - as well as the first blackout since most 6 hours (which happens often) determines the total loss of warranty. It is reasonable to imagine that the buyer, which turned off the light of day, will not sits all day in the absence of light, zhdya coming the next day. In general, in fact, a similar limitation on the work looks pretty amazing: It seems as clear that the miniature generator with cooling air is not able to operate around the clock. While that still causes inconvenience to cool the generator, for example, for 1 hour, and then resume his work? In solid power installed thermal disconnector, which simply will not allow too much power to warm up, and therefore, the decision on mode of operation.

Alright, so Tungsten (which you may or may not know, is my favorite element) is combustible when current passes through it while it is exposed to oxygen. Could I place a bit of tungsten I scavenged from a lightbulb in a small pool of gas (or alcohol) while running 9 volts through, and get a reaction? Would having the whole bit of tungsten under the gas work, or would I need a piece above the gas also? I'm not looking to blow things up, just trying to do a bit more "dangerous experiments" before school starts. Thanks all!

I have a 33cc gas scooter (sounds nerdy, I know), on the side I can make out what looks like Moto Rebel but not sure. It was used twice, sat in garage for one year without gas in the tank, then sold to me for $20 (Amazing price for something that's $350 new). Like new! It is 2-stroke but am unsure of the model number. It starts runs on choke between a small margin but won't run on ON, which is above choke on the switch. I think it may need the idle screws adjusted but am unsure. Has new and correct gas oil mix in tank and has primer button. Help would be appreciated.

I get a text yesterday "Hi Dad, Are you going to be home soon? I left the house and forgot to turn off the grill." The grill is in the back yard, a few feet from the kitchen window. The grill connects directly to the house gas supply, so it will never run out of gas. I have found the grill on days after someone finished cooking. So far, we haven't burned down the house! I am searching for a product that would put a large blinking light on the kitchen window. It blinks when the grill is hot. It would remind me and my family to turn the grill off. Anyone know of a product that I could buy to do this? Seems like a natural Arduino project, I'm just short of time now to make it. Thanks, in advance. -Frank

I am looking to building a 12 volt generator from an alternator. I want it to have a car battery (or a deep cycle battery if it's easy to integrate) for quiet operation. I want the output to equal that of a 12V car plug socket so I can easily invert it to 110 volt AC. the engine will need to be small as possible without stalling on high demand. I guess it would have to have the same circuitry of a cars main power circuit. So, can someone give me a few tips on making this? And most importantly, a schematic. I can't seem to find a basic car circuit.

Everybody knows that rising gasoline and fuel prices are taking a toll on consumers' wallets. But few anticipated this problem: a shortage of numbers at gasoline stations. Since gas prices have easily surpassed $4 per gallon, gas stations in New York don't have enough 4s to advertise their prices--so they've had to improvise and make DIY numbers.Of course, with gas expected to hit $5 per gallon soon, some stations are prepared: On Monday, at a BP station on Coney Island Avenue and Lancaster Avenue in Gravesend, Brooklyn, a 2 had been turned upside down to make a 5 for the large sign on the corner.When the price hits the $5.20 range, though, they'll probably have to start improvising again.New York Times

Question by AtomRat | last reply
The exact setup I have is a little difficult to explain, but basically I'm designing an extremely simple heat engine, based on boiling ethanol, and need to be able to mechanically alternate the flow of vapour. I have a little boiler, sealed except for a pipe out of which the vapour escapes. This lifts the column of ethanol in the pipe, pouring it into a water wheel which turns. The ethanol then runs back through a second pipe into the system to be pumped up again. It works, and fairly well since I'm not looking to get a lot of power or efficiency, but only if I pinch the tube on and off. This allows the bubbles to collapse, which sucks in more ethanol to replace them. When I release the tube the bubbles rush out, lifting the eths, and repeat. I have two valves to keep the system one directional. So now I'm looking for a way to automate the opening and closing of the gas feed. I've been trying a few things but nothing seems to work well enough yet. The other consideration is that; due to the nature of the larger project, whatever I use has to be extremely simple to construct, preferably from reclaimable materials. 1 second on, 1 second off seems to work best. Any ideas? cheers, Daniel.

Hi Really need some help with this one, have searched everywhere but cant seem to figure it out. I know there is probably a very easy solution i'm missing so please help. Basically I want to compress CO2 at around 80 psi into a hollow metal. I have drilled a micro hole and created an opening (about 2mm radius) into the metal. My problem is after I compress the CO2 in there how do I remove the compressor nozzle and seal the hole without the CO2 escaping. The metal is small and there is no place for a valve. Is there such a thing as a self sealing removable valve? Or could I use a valve with two openings and pump liquid metal (that would than solidify) and seal the hole so I can remove the compressor?

The short version: I want to make hydrogen to fill model airship envelopes with, because screw helium. Help me make a cheap electrolysis device that can do this in under an hour (ideally), or come up with an even better system for production. My immediate problem is that I need a high-surface electrode that won't fail in a solution of sodium hydroxide.The long version:I've devoted a fair portion of my time to contemplating airships, primarily because they're awesome. Fell out of use with the rise of much faster aircraft, and the technology its fate sealed by the extraordinarily bad rep the Hindenburg gave it. It is still far from useless, however, in that lighter-than-air systems can lay claim to flight times measured in days, and sometimes months, thanks to the fact that they literally float in the air like a boat floats in water.Their day may have come and gone, but I still want to experiment with the technology and create some model airships of my own. Helium works okay as a lifting gas, but it remains expensive and isn't going to get any cheaper in the foreseeable future. It is for this reason that I am pursuing hydrogen, in the hope that I might be able to produce a cheap lifting gas for my projects. Unfortunately for my aspirations, hydrogen is surprisingly hard to get cheaply in decent quantities. Here's what I've figured out so far.For one, it is absurdly hard to find sites that don't veer into fringe science when talking about hydrogen. HHO production, Joe cells, power your car with water...it all keeps cropping up, and not only does none of this do what I want, the concepts are often poorly documented or riddled with problems. However, I have been able to glean some information from my research. First off, one of the easiest methods (and the one I'll be pursuing the most) of hydrogen production is through electrolysis. For those of you unfamiliar with the concept, you can basically take two electrodes, stick them in water, add some electrolyte (like regular table salt), and apply a decent voltage. You'll get hydrogen gas streaming out of the negative electrode and oxygen out of the positive electrode. Fancier systems use large tanks, platinum electrodes, and a strong acid or base as the electrolyte. To increase efficiency (yeah, it's not 100% efficient), there is ongoing experimentation with high-temperature electrolysis and ongoing research into an effective electrocatalyst.Now, when I did my research, I thought "Hey! This sounds easy! I'll just set the system up like explained, and away we go!" Unfortunately, those exclamation marks were unwarranted. My first attempt showed that production is mind-numbingly slow with small electrodes. Using salt had the wonderful side-effect of producing chlorine and sodium hydroxide, a.k.a. caustic soda. It's called that for a reason, and I'm lucky I didn't run it too long or I might have a chemical burn now. Now I know. Choosing a good electrode turns out to be a problem too, as most conductors oxidize quickly or dissolve in the solution (now I know why everybody uses platinum when possible). My aluminum foil electrodes in a sodium hydroxide solution? Yeah, that didn't work AT ALL. I had better luck with steel mesh, but I recently found that it seems to fail over time too. The only thing that isn't disappointing is the container and the collection apparatus: an inverted plastic bottle with some airtight hose running off it, connected to a gas valve. If the bottle is placed such that forming gas causes the internal water level to be lower than the external container water level, the gas will be pushed through the hose (no pumping necessary!). There was one good thing I discovered, however. Apparently there was a bit of soap or something left over in the container, and I ended up forming a bit of explosive foam as well. The hydrogen foam blows up like nothing else, and the oxygen foam makes a loud pop and sends (slightly) caustic foam all over the place. Totally useless but still somewhat cool, so long as you're not fool enough to do it in large quantities.So, as of right now, I've got a good container and collection system, but my electrodes suck and production rates are so low that it'd take me hours and hours to inflate a good-sized balloon anyway. I'll be using sodium hydroxide in the future as the electrolyte, skipping the chlorine production and observing the proper safety procedures. My top priority is finding a good electrode, my next is finding a good way to increase surface area, and my last is getting a higher voltage source than the 12V power supply I had lying around. Any ideas?
