What the hell happened around here? 70% of the comments are people trying to correct you or question your design. Like they think this quick fume hood is worse than just doing everything you do outside or with a window open lol.
Well he needs to put an air scrubber on it. Sure he might not be breathing in those harmful gases, but the environment is. Unless you put an air scrubber on it that helps the environment then there is no reason to even have that
Outrage Quitter lol right he's just saving himself some time and money because "just working outside" comes with its own issues like unstable temperature wind blowing acid/toxic fumes in your face pet's drinking something bad just to name a few
I watch cody because always has a basic understanding of what he's doing . His experiments are founded on this knowledge that he's trying to expand upon . I'll always give him the respect that he knows what he's doing . All this quibbling is about the mechanics of his design . Very few have put good facts out there Just stupid opinions
Because a lot of people LOVE to point out what someone else does wrong; I guess it makes them feel better about themselves because they believe they're smart(er)? People might be entitled to their own opinions, but no one is required to listen
@ElectroBOOM, Can't do a experiment with flammable gases and a regular extension cord with a circuit breaker. To make sure @Codyslab don't go BOOM when switching on or off the fume hood. 😂
ElectroBOOM could save his family with a fume box, no? I've melted resistors, caps, transformers (my insatiable deconstruction fetish)... and they *stink* for hours.
Wow I just looked at the sub numbers and never realized how many people are interested in Cody's stuff. I subbed at around 70k because I love chemistry and geology and all the stuff Cody does. He even got me into beekeeping! Congrats man it makes me happy to see you doing so well!
Hey Cody that looks really good, the only suggestion I would make would be a grate over the air inlet inside the box so you don't get stuff sucked into the fan accidentally. I would use a chunk of 1/4" galvanized gardening screen.
Id be a little worried about corrosive stuff with all that electrical and galvanized in the box. zinc is pretty reactive as is the copper in the electrical.
Those plants out there are going to either wither and die or mutate and become super-vegetables after being exposed to all the exhaust that will come from your fumehood.
Pleased to see you are trying to protect yourself. As an industrial chemist who has, in the past, designed chemistry labs I can honestly say that sulphuric and nitric acid fumes will eat through that metal fan and ducting in no time at all, you need plastic replacements; would also advise ducting the fumes upwards once outside the window and narrowing the bore to accelerate flow thus preventing blowback and will help with dispersion of the fumes. Heavey metal fumes over the food plants is not advisable. Anyway, great vid and thanks for sharing.
I would move that power strip outside the cabinet and silicone around all the entrances to that light fixture. Those fumes are going to kill everything copper in that cabinet.
Actually he should put the lights external to the cabinet and have them shine through another acrylic window on the top of the box (like in a normal fume hood)! The corrosion is going to be a huge problem inside the lights, as you said.
LOL! I think Cody has found the secret to choosing his neighbors. Not liking the new neighbor? Hmm....what have I got around here that I can mix that won't kill them, but just make them move.
Hey cody, why don't you just use a hook and loop instead of nails? If you screw some metal loops in on the outside of the box and put a hook on the door, you won't have to put nails in or take them out, so you'd be able to adjust the height much more quickly and easily.
The hook is on the outside face of the door, while the loops it hooks onto are on the outside edge of the box. There is nothing in the path of the door as it slides down with this method, allowing you to slide it to any position and hook it there immediately without adding or removing anything.
I am so happy you have the same enthusiasm and raw content that you did when you started this channel. That’s what makes this content so amazing. You are the spirit of science, man!
i like the fact that you re-purposed the box instead of buying a new one it shows your creativity and now we don't have to worry about you passing out in the lab wile experimenting.
You are lowering the pressure in your garage with that fan. Where is your garage going to pull fresh air in from? If the path of least resistance is near where you are venting the exhaust, some of the fumes may make their way back into the garage.
I would argue that if anything he is venting is dangerous enough to worry about that small of an amount coming back in, then there are bigger issues to worry about like a neighbor walking by down wind.
This is really cool. Hope you made something to close the window so it doesn't suck in the air you're trying to blow out. Really excited to see what you do with this.
Congrats, on finally getting one; I know you've wanted one, for quite a while. You've probably read/heard of it already, but beware of creating/using flammable gasses, due, to the motor of the fan, might be the brushy type; hence, it could potentially create sparks/surfaces to ignite on.
NileRed's one was relatively cheap - it was a great deal for a chemically resistant fume hood, which is superior to Cody's ... but Cody's will still do the job, which is important :)
Glad you did this. We all want you around for more videos! Don't ask how I know those particular fumes are so nasty (cough, hack). And yes, I've had wind changes bring them back to another window. A good duct outdoors (even that flue pipe) will be a good idea when you get a round tuit.
Hello Cody, maybe you should make the transparent door with PVC rather than plexiglass because Plexi is not very resistant to chemical attacks (solvent stains tend to be really opaque white)
@Cody - You might think about using PCV pipe instead of galvanized steel for the piping, and create some sort of tube-in-shell venturi to protect the motor and blower from being exposed to the exhaust stream directly. Fumes from mineral acids are going to do a number on all of that assembly very quickly.
In reality they'll fail quicker because the cold-solder joints made with non leaded solder are already half cracked and will fail completely with chemical exposure.
I love your build. I am facing the same issue, needing a fume hood and every "proper" solution ends up being $1k+. Just keep in mind that the wood is all flammable, so be careful with open flame around the enclosure. You can buy cylindrical carbon air filters on eBay that attach inline to your exhaust that would work pretty well for a lot of the organic vapors being discharged.
If I had to guess, that box was probably used for something like concert or theater equipment. It has that kind of look, and the build/handles are pretty common in that use. Snagging that was a pretty good find, even if it is a bit worn down. Obviously it's not laboratory-grade like you'd find in a university research lab, but it was pretty ingenious. You made it to suit your needs, and it should work. Like you said, it'd likely be a good idea to put down some kind of containment tub and some tile to protect the interior, as the paint can only do so much. And again, like you said, if you're going to be deal with anything particularly nasty, you'd probably want some kind of air scrubbing. But for what you're realistically going to use it for, I'm sure it's pretty much perfect. It gets the fumes out of the house, and it disperses them outside. I think that's way better than setting up in the yard and just hoping that it's breezy enough to keep the fumes moving. Now you have a reliable airflow that will disperse the fumes, instead of sitting in a cloud of fumes on a windless day in the yard. All of that said, I'm not a chemist, not in the slightest. I'm a college student, studying civil engineering, so this is out of my expertise. I'm mechanically inclined. And while I have a basic idea of handling chemical materials and building to be resistant to them, I will happily defer to the ACTUAL chemists, as well as those with more experience. It goes without saying that you and others with specialization in this field know more than I do about this.
Great idea Cody !! I'd like to see the blower hooked up outside with the flexible duct dangling near the window, ready for when you need it. That way the noise will be far away from the microphone.
awesome build. I agree with others about adding a back up fan and the switch outside preferably closer than hands reach. with the door fully closed how much vacuum does it make inside? Are you going to build an exhaust scrubber for the fume hood? don't want those nasty fumes hurting your plants or neighbors. Also please add a small fire extinguisher to this build just in case. What happened to the large vacuum chamber you were working on?
That fan pulls so much air through there I don't think any caustic fumes will sit around long enough to degrade the electric output bar. And that motor isn't brand new either so it's a great starting point nonetheless
For the kind of work you do, you definitely needed that. I think it would have been better to place the suction duct at the center top with tapered walls directing the fumes into the duct. .
Looks great. Like you said tiling the floor would be a good idea. I would also put up some stainless steel sheets on the 3 walls and ceiling. You can get activated charcoal filter media by the roll on ebay if you wanted a exhaust filter.
Hey Cody! great job! heres a tip: candle wax makes an ideal lubricant for wooden runners like the sides of the door. rub some candle wax along the rails and the door will operate way smoother :)
For extra protection you can use ptfe coated fiberglass in the walls of the box. That thing resist heat very well, practically inert to most chemicals and its cheap.
Looks good. Buy some adhesive backed felt tape and make a seal along the top and sides. Will seal it, make the door slide much smoother and will protect the plexiglass from scratching.
I just wonder about a few things with this design: 1) How well will that fan resist corrosion? 2) Aren't you concerned about your plants right outside getting affected? 3) Shouldn't you seal the wood on the inside to prevent the paint from reacting with anything, even the moisture in the air?
dungeonseeker1uk a hdpe plastic taped around the window & exhaust would work easy, he showed the window but not at the end running it. Cody's smart enough to do something along those lines. I did see what you're referring to.
Yeah, I was thinking the same - if he have it the way he show in this video (without adding any seal around it), a lot of the fumes will enter that room again. Even with no wind - sucking air out of the room causes the pressure to drop - that means air has to get in somewhere else to level out the pressure. One of the easiest way for air to get into the room is to get back in thru the window around the fan outlet (that air will then of course take a big part of the fumes with it)
That fan is moving a lot of air it would take some very fast winds to cause it to come in reverse. But I agree it does need a chimney or something to keep rain from coming in.
Really well set up!! I have a thought on the fume hood, you may have already considered it though. If possible find a way to regulate the blower speed; maybe a variable output power adapter would work. That way you can manage the fumes as needed if it doesn't show any harm to the blower motor in there. Otherwise it looks amazing CoDy!
Are you sure the gases you produce are safe to pass through the tube? For instance, NO2 would react with any water that may be present on the air tube and make nitric acid, and dissolve away the metal tube. Chlorine might also eat through the metal.
A baffle at the back with slots below and above like a traditional fume hood to prevent that 'swirling' and to drag most of the fumes down and back would help. And cant' wait to see the fan in a few years, all nicely eaten with acid. :) However it's nice to see some descent, if noisy extraction. :)
Amazing fume box! I think I will need to get one of these because some my chemistry experiments have toxic fumes involved and I don’t want to breath it in.
Hey Cody, just wanted to point out something to be considered. I am no expert on this matter but is it good to have exposed electrical socket like your extension for the light to be in the fumehood?
What kind of electric motor does the ventilator use? Is it suitable for flammable fumes? (Just to be sure nothing bad happens, although I'm sure you've thought about everything :) )
most likely its a shaded pole motor or a capacitor start induction motor, probably not rated officially for use in flammable gasses but its unlikely to be a universal motor with brushes which will arc. shaded pole is how most furnace/boiler flue assist fans are constructed.
Well done Codey - although just a little noisy, your general design works better than some fume-hoods at universities! Just make sure sucked out gases/fume is diluted quickly and doesn’t have a chance to enter again. Great work for your safety - keep it up
If you need a cheap scrubber then the charcoal filters they use for hydroponic gardens are pretty cheap and available... might need to go to some sketchy stores to get one though :)
Consider calculating the cross-sectional area of the exhaust. Then determine how high you have to raise the door to have an opening equal to that same area. Mark the door frame so you can always avoid straining the fan motor. Cleaning tile will be a nuisance because the joints between tiles will be a little uneven and the grout will stain. Consider formica or melamine. I used to work with a fume hood that had an epoxy base. It was great! It was resistant to everything. You certainly have the DIY skills to make one. From a home improvement store you can get epoxy floor coverings that should work well. Also, are you aware that epoxy paint is commonly used for bench tops in chemistry labs? I think it would also be available from a home improvement store, but for sure you could get it from a scientific supply house like Fisher, Wards, Preiser, etc.
Dunno what material your fan is made of but depending of what exotic stuff you try, it might melt or start degrading - similar zu ABS plastic being exposed to acetone. And it it's made out of metal... urgh. It's gonna suffer either way. xD
RetromagneticDesigns this fan has definitely metal fanblades . Its huge an would break of it was made out of plastic , I have worked with similar fans before ;)
That was my first thought with the Plexiglass and acetone. It might end up being ok, as long as he doesn't touch it while any acetone is on it. Once the acetone evaporates, the acrylic will just go back to normal. It might even polish it up on the inside some. I have seen people polish plastic castings using acetone vapor.
It's a typical household blower used for heating with forced air and just blabout anything else you would need to move air, it's all metal and ment to last for years with no maintenance.
Hey Cody, Nice little hood there but id like to recommend some changes (coming from a research and development chemist with abit of experience knocking together makeshift hoods and reactors). Id make the tiles a priority as any oxidant spilled on the wooden surface (such as nitric acid) could be a real fire risk even after being cleaned up. Maybe put them 1 tile width up the side; encase of any serious spills. Some form of lip at the front is also a good idea for similar reasons. Another issue is the fan, it may actually be to fast causeing turbid air which can negatively impact the flow in the hood. And lastly (most importantly as this effect you and innocent bystanders) install a stack and have the fan near the top if possible. This will reduce the flow speed making it more laminar and will move the escaping fumes higher allowing faster winds to catch them and remove them safely. NO2 is nasty and could easily get you a visit from the local police worried what you are making. Regards Ryan (long time fan even used some of your refining videos during my undergrad research)
lol Mine is a ducted fan (intended for electric radio controlled jet planes) with a polystyrene "gasket" jammed into a length of donkey dick, through a piece of wood that the window closes against, suspended from the ceiling with some tie wire. They do put out 3.5 KG of thrust though and move a metric SHIT TONNE of air. The room it is in is 12 meters x 6 meters with 12 foot ceilings.... you can feel the air returning from the other end of the room inside of 2 seconds (whirlpool style)
Hey Cody, couple pointers. First, look into getting some silicone to sure up the seal around that exhaust port. Second, consider just doing a 3-way light so you can control the lights and or fan from more than one spot.
Cool DIY Cody. Reminds me of my Grandfather making an elevator at his cabin. Not going to go with the trolls and say what's wrong, but make a suggestion on the door. Convert the door to a casement window type setup. Put some pulleys on the top and counter weights. That way it won't accidentally slam down on your hands some day.
I would use patreon but then I'd be poor. All the creators I want to support... there are like 20 of them. If they invent a way for me to make a weekly payment and it gets split between all the creators i want it to then I will consider it. I do what I can and turn off adblock for the creators I think deserve it.
Finally some basic safty cody. That makes me happy. One idea to make you enjoy your creation longer. If this seal creates itselfe you will end up with scratches if you move the screen when the fan is on. You could put something soft there :-)
Cool build Cody! Seems there are many knowledgeable people in the comments section. I don’t claim to be anything special but I’m impressed with your build, it’s basic enough to encourage others to try constructing their own if they are carrying out similar backroom mad scientist things!! Keep up the great work Charlie UK
@Mark incandescent bulbs don't flicker at all, the filament doesn't have time to cool down in between voltage peaks. And some cheap fluorescent fittings don't use a high frequency ballast, instead having a transformer type ballast which runs at mains frequency and do flicker.
Cody, excellent project. You could add a nederman arm to get the intake right over the target. Just watched for vortices/eddies in areas of the cabinet that accumulate fumes that might be released when you switch off the extractor. One question: Whenever you do anything now, do you naturally want to film yourself? i'm not there yet but I'm starting :)
Kristyanna Virgona well as long as the fumes are heavier than air (which it would almost have to be since it flows up through the vent) they won't reach the plants. But it should still probably be filtered as he said he would
you could use a welding fume extractor... these things are very high power and can filter out lots of bad stuff already out of the box, so you won't have to modify them as much as lets say a cooking fume extractor or something
Hey Cody, I would suggest you mount the power strip outside to limit it's exposure to potentially corrosive fumes. It might also be nice to put in a variac or dedicated speed controller for the fan.
please be careful if your starting chemistry or using it as a hobby please do things with passion and knowledge and not intent for money or fame, some things can be very dangerous without the full care of common sense. fumes and vapors can be dangerous to health when unseen or unknown. but good luck just make sure you know what you are doing and dont try things just because others have.

I bet you'd short something and burn your fingers just painting the box. :P
ElectroBOOM could save his family with a fume box, no? I've melted resistors, caps, transformers (my insatiable deconstruction fetish)... and they *stink* for hours.

When is the reactor scheduled for? And how is the Mars thing going?
Hey Cody that looks really good, the only suggestion I would make would be a grate over the air inlet inside the box so you don't get stuff sucked into the fan accidentally. I would use a chunk of 1/4" galvanized gardening screen.
Ryan Gribble
Ah good call.

Cody. Please take in account if you could have hydrogen gathering in top, where you have extention cord.
Codys Neighbor: "Do you smell something?"
You'd think at this point he'd be used to his crazy neighbor with the bees, the machines, the pumps, the fumes etc...
I don't think he has neighbors close to his place.
lol just a joke
*dies*

This video began like a conversation with my mom: half of it seems to have commenced before I was involved.
Uriah Siner This is youtube gold right here. Thanks for this comment
and then it ends with you running for the hills.
For a second, I thought you might have been the real Grumpy Cat. I was going to ask for an autograph...er, paw print maybe.
SwapPart TV Repair no.
I seen you somewhere commenting.
And it's not too hard to hear you over it, though I thought it definitely would be!
Micah Philson how is your comment from 8 hours ago?? The video was uploaded 5 mins ago, is it a patreon perk
sam neale Yes, patreon.
sam neale Nope, he is a time traveler.
Nah, it's more likely that he found a Genie and used one of his three wishes to view Cody's lab videos 8 hours in advance.
Inductor, I'd make a joke, but that's exactly what I'd use a wish for, I'm sure!
Those plants out there are going to either wither and die or mutate and become super-vegetables after being exposed to all the exhaust that will come from your fumehood.
Well the nitrogen dioxide is a fertilizer.
how did you comment on this 8 hours ago when i came out 10 minutes ago?
Tom Horncastle patreons get early access.
I wondered if it was worth extending the vent a little so if you are working with anything harmful it wont take all the paint off your house?

Carbon diselenide should do the trick. ;)
Cody'sLab or thioacetone,but it is quite hard to crack the trimer at 400-600°C and then you need to handle nice smelly liquid....
Hey cody, why don't you just use a hook and loop instead of nails?
If you screw some metal loops in on the outside of the box and put a hook on the door, you won't have to put nails in or take them out, so you'd be able to adjust the height much more quickly and easily.
Dick Nickler all the nail did was block the wood, the hook would have the same effect, so doing that would result in not being able to move it at all
The hook is on the outside face of the door, while the loops it hooks onto are on the outside edge of the box.
There is nothing in the path of the door as it slides down with this method, allowing you to slide it to any position and hook it there immediately without adding or removing anything.
Or a chain with large enough links to host a nail, plant a nail somewhere and use the chain itself as a lock :)
I am so happy you have the same enthusiasm and raw content that you did when you started this channel. That’s what makes this content so amazing. You are the spirit of science, man!
Next episode: Cody builds an ISO 9 clean room out of wood in the backyard.

Open a door?
I think Cody said in his mercury vacuum pump video that his garage isnt sealed well at all, so I'm guessing it wouldnt be an issue.
Jon Luke: I'm worried those bricks in that brick wall on the right are going to radiate him to death in, Oh, 500 years or so.
Obviously I'm terrible at my job because you think fluid dynamics is subject to your own opinions. Touche.
This is really cool. Hope you made something to close the window so it doesn't suck in the air you're trying to blow out. Really excited to see what you do with this.
The beauty of your channel is that you show how accessible science can be, if you really try. Wonderful
Perfect! Vented right on his vegetables. I've seen sci-fi movies start this way lol. 0_o ;)
Return of the Killer Tomatoes! Featuring George Clooney =)
I'd watch lol.
You can watch, because I wasn't joking xD

at least those tomatoes won't suffer the lack of the nitrogen =D
This is a fine job at a DIY fume hood, Cody. Thank you for having great content!
Back again with the paranormal activity jumpcuts 😂
that's exactly what I thought )))
Congrats, on finally getting one; I know you've wanted one, for quite a while.
You've probably read/heard of it already, but beware of creating/using flammable gasses,
due, to the motor of the fan, might be the brushy type; hence, it could potentially create sparks/surfaces to ignite on.
NileRed blows BIG cash on actual fume hood.
Cody just builds one. lolz
psygn0sis I did building stuff over buying if I can help it. Makes for a better feeling of accomplishment.
NileRed's one was relatively cheap - it was a great deal for a chemically resistant fume hood, which is superior to Cody's ... but Cody's will still do the job, which is important :)
I love that you haven't changed too much Cody, even though you are getting quite big on youtube. And no click baity titles.
I am not too surprised that you built one instead of buying one. That's what you do most of the time :)
Agreed. I would have been shocked if he bought one.
Glad you did this. We all want you around for more videos! Don't ask how I know those particular fumes are so nasty (cough, hack). And yes, I've had wind changes bring them back to another window. A good duct outdoors (even that flue pipe) will be a good idea when you get a round tuit.
Hello Cody, maybe you should make the transparent door with PVC rather than plexiglass because Plexi is not very resistant to chemical attacks (solvent stains tend to be really opaque white)
@Cody - You might think about using PCV pipe instead of galvanized steel for the piping, and create some sort of tube-in-shell venturi to protect the motor and blower from being exposed to the exhaust stream directly. Fumes from mineral acids are going to do a number on all of that assembly very quickly.
Could you use LEDs instead of a neon light. The color will be better and its probably safer.
In reality they'll fail quicker because the cold-solder joints made with non leaded solder are already half cracked and will fail completely with chemical exposure.
that's why I hate ROHS
I worry about him accidentally gassing his gf if she unwittingly gets downwind of him when he's not expecting her to be nearby.
love your memes. I've been subbed for abit now
His girlfriend knows better, And Cody isn't the type not to warn his girlfriend before playing with something extra dangerous.
I love your build. I am facing the same issue, needing a fume hood and every "proper" solution ends up being $1k+.

I have this feeling we're going to see a lot of the inside of this box
Great work recycling a bunch of older used items into something usable Cody. Love the channels keep up the awesome job!

What happened to the large vacuum chamber you were working on?
oh come on you can't tease us with that intro clip and then not show how that ended.
Pretty sure I showed that in another video.
If you did, I can't find it. Please link if you have time.
Yeah I have never seen that video either.
I don't think I saw it too.
it's on patreon... ;-)
Nice looking fume hood......I loved the beginning of this video.....we've all been there when things didn't go as planned.....
I never thought about building a fume hood out of wood! However being in the open air works as well.
I wouldn't have put electrical fittings inside it, either. Or have that fan and motor exposed to the fumes.
yeah this is super dangerous...
That fan pulls so much air through there I don't think any caustic fumes will sit around long enough to degrade the electric output bar. And that motor isn't brand new either so it's a great starting point nonetheless
As long as nothing flammable or explosive gets in there he should be fine, right? And Cody would never do something like that, right? Right?
Until the wind suddenly changes direction towards you. I still remember inhaling silfur smoke as if it was yesterday.
Cody. Building safety equipment. I'm shocked and impressed. Nice one.
I wish next time was an hour from now. Want to watch so many more videos.
Well done! People who have never worked without a fumehood can't even imagine what kind of luxury it is to have one.
cody poisoning the neighborhood
You should put a piece of flex hose on there.
Nice reusing the box.
If it gets too loud you could always remote mount the fan and add a piece of duct.
I want to see the result of the first reaction.... it looks like it went a little toooooooo crazy
For the kind of work you do, you definitely needed that. I think it would have been better to place the suction duct at the center top with tapered walls directing the fumes into the duct. .
Do a lab tour please
Agreed!
Did you blink? That was it!
Looks great. Like you said tiling the floor would be a good idea. I would also put up some stainless steel sheets on the 3 walls and ceiling.
You can get activated charcoal filter media by the roll on ebay if you wanted a exhaust filter.
What the hell happened in the beginning?
A ton of nasty toxic gases result of playing around with equally nasty and toxic acids. Something you'd want to take away from you ASAP.
yeah yeah, we need a full cut ))
A preamble showing why Cody needs a fume hood.
Cody slipped on "butter". Once again...
Yeah is this from a previous video or something? I would like to see what happened before, as well as the aftermath :p
Hey Cody! great job! heres a tip: candle wax makes an ideal lubricant for wooden runners like the sides of the door. rub some candle wax along the rails and the door will operate way smoother :)
If the bees die we know why.
Paul None Ya Right into the garden:)
I thought that was an oversight too, hopefully the scrubbers will protect the garden. Overall good idea though
Maybe he will accidentally create some super bee that is immune to mites or something... or Beezilla will come and attack Salt Lake City
Cody: "So basically I'm going to pump my NO2 gas directly onto the plants and bees I've been working on for the past 3 years. It works great."
Next time on Cody’sLab: nitric acid honey
Cody is gonna be on of "those" neighbors who starts the compressor at 3 in the morning :D
Use a smoke gren to test its effectiveness without the door :)
A "smoke green"?
ah shit... autumn correct at it again
and again
....im done. Just no. does it think it's funny or something?
I'm assuming you mean 'smoke grenade'.
For extra protection you can use ptfe coated fiberglass in the walls of the box. That thing resist heat very well, practically inert to most chemicals and its cheap.
Is this a sneak peak for the silver from tuna video?
Looks good. Buy some adhesive backed felt tape and make a seal along the top and sides. Will seal it, make the door slide much smoother and will protect the plexiglass from scratching.
*We get it Cody, you vape....*
I just wonder about a few things with this design: 1) How well will that fan resist corrosion? 2) Aren't you concerned about your plants right outside getting affected? 3) Shouldn't you seal the wood on the inside to prevent the paint from reacting with anything, even the moisture in the air?
And then the wind changes direction and blows nasty fumes coming out of the outlet straight through the window.
bdf2718 that's why the window is sealed around the output vent. To prevent that, otherwise it's for nothing
yeah, definitely a chimney tube asking to be installed.
dungeonseeker1uk a hdpe plastic taped around the window & exhaust would work easy, he showed the window but not at the end running it. Cody's smart enough to do something along those lines. I did see what you're referring to.
Yeah, I was thinking the same - if he have it the way he show in this video (without adding any seal around it), a lot of the fumes will enter that room again. Even with no wind - sucking air out of the room causes the pressure to drop - that means air has to get in somewhere else to level out the pressure. One of the easiest way for air to get into the room is to get back in thru the window around the fan outlet (that air will then of course take a big part of the fumes with it)
That fan is moving a lot of air it would take some very fast winds to cause it to come in reverse. But I agree it does need a chimney or something to keep rain from coming in.
Really well set up!! I have a thought on the fume hood, you may have already considered it though. If possible find a way to regulate the blower speed; maybe a variable output power adapter would work. That way you can manage the fumes as needed if it doesn't show any harm to the blower motor in there. Otherwise it looks amazing CoDy!

Actually I’m down to 6.
Are you sure the gases you produce are safe to pass through the tube? For instance, NO2 would react with any water that may be present on the air tube and make nitric acid, and dissolve away the metal tube. Chlorine might also eat through the metal.
Dude, was that a firing pin keeping the hood up?
Those are nails which are made to be easily pulled later, they have sort of 2 heads to them.
...Of course, with Cody you never know.
A baffle at the back with slots below and above like a traditional fume hood to prevent that 'swirling' and to drag most of the fumes down and back would help. And cant' wait to see the fan in a few years, all nicely eaten with acid. :)
However it's nice to see some descent, if noisy extraction. :)
Cody's Fartbox
Gotta keep a hold on the nasty gas...
I laughed way to hard at that. Sorry Cody
Amazing fume box! I think I will need to get one of these because some my chemistry experiments have toxic fumes involved and I don’t want to breath it in.
I thought you started a vaping club, Cody.
Hey Cody, just wanted to point out something to be considered. I am no expert on this matter but is it good to have exposed electrical socket like your extension for the light to be in the fumehood?
What kind of electric motor does the ventilator use? Is it suitable for flammable fumes? (Just to be sure nothing bad happens, although I'm sure you've thought about everything :) )
In the next video we make flamethrower with our fumebox
most likely its a shaded pole motor or a capacitor start induction motor, probably not rated officially for use in flammable gasses but its unlikely to be a universal motor with brushes which will arc. shaded pole is how most furnace/boiler flue assist fans are constructed.
It is good you have done this finally. Now we can keep you around for a while comrade.
You should laminate inside with stainless steel or teflon
Well done Codey - although just a little noisy, your general design works better than some fume-hoods at universities! Just make sure sucked out gases/fume is diluted quickly and doesn’t have a chance to enter again.
Great work for your safety - keep it up
Right out the window...... and right into the neighbors. lol
You know he doesn’t live in the city, right?
Cake Quest Developer test That exactly where he is in this video. Lol
Cake Quest Developer test he's not at his parents. He's in a residential neighborhood off a busy street..... hear that traffic??
I don’t think the suburbs are the same a the city, but with at least 3meters between the houses, the fumes won’t be a problem for the neighbors
If you need a cheap scrubber then the charcoal filters they use for hydroponic gardens are pretty cheap and available... might need to go to some sketchy stores to get one though :)
Where was that intro clip from?
I think its from a future project, but he just used that scene to illustrate the problem that he's been facing.
Consider calculating the cross-sectional area of the exhaust. Then determine how high you have to raise the door to have an opening equal to that same area. Mark the door frame so you can always avoid straining the fan motor.
Cleaning tile will be a nuisance because the joints between tiles will be a little uneven and the grout will stain. Consider formica or melamine.
I used to work with a fume hood that had an epoxy base. It was great! It was resistant to everything. You certainly have the DIY skills to make one. From a home improvement store you can get epoxy floor coverings that should work well.
Also, are you aware that epoxy paint is commonly used for bench tops in chemistry labs? I think it would also be available from a home improvement store, but for sure you could get it from a scientific supply house like Fisher, Wards, Preiser, etc.
Dunno what material your fan is made of but depending of what exotic stuff you try, it might melt or start degrading - similar zu ABS plastic being exposed to acetone. And it it's made out of metal... urgh. It's gonna suffer either way. xD
RetromagneticDesigns this fan has definitely metal fanblades .
Its huge an would break of it was made out of plastic , I have worked with similar fans before ;)
That was my first thought with the Plexiglass and acetone. It might end up being ok, as long as he doesn't touch it while any acetone is on it. Once the acetone evaporates, the acrylic will just go back to normal. It might even polish it up on the inside some. I have seen people polish plastic castings using acetone vapor.
It's a typical household blower used for heating with forced air and just blabout anything else you would need to move air, it's all metal and ment to last for years with no maintenance.
HCl is pretty nasty for galvanized tin.
true, which is why it will be interesting to see how long it lasts. The reaction takes time which the air movement will not give.
Hey Cody, Nice little hood there but id like to recommend some changes (coming from a research and development chemist with abit of experience knocking together makeshift hoods and reactors). Id make the tiles a priority as any oxidant spilled on the wooden surface (such as nitric acid) could be a real fire risk even after being cleaned up. Maybe put them 1 tile width up the side; encase of any serious spills. Some form of lip at the front is also a good idea for similar reasons. Another issue is the fan, it may actually be to fast causeing turbid air which can negatively impact the flow in the hood. And lastly (most importantly as this effect you and innocent bystanders) install a stack and have the fan near the top if possible. This will reduce the flow speed making it more laminar and will move the escaping fumes higher allowing faster winds to catch them and remove them safely. NO2 is nasty and could easily get you a visit from the local police worried what you are making.
Regards Ryan (long time fan even used some of your refining videos during my undergrad research)
Worlds jankiest fume hood. Check
lol Mine is a ducted fan (intended for electric radio controlled jet planes) with a polystyrene "gasket" jammed into a length of donkey dick, through a piece of wood that the window closes against, suspended from the ceiling with some tie wire.
They do put out 3.5 KG of thrust though and move a metric SHIT TONNE of air. The room it is in is 12 meters x 6 meters with 12 foot ceilings.... you can feel the air returning from the other end of the room inside of 2 seconds (whirlpool style)
Hey Cody, couple pointers.
First, look into getting some silicone to sure up the seal around that exhaust port.
Second, consider just doing a 3-way light so you can control the lights and or fan from more than one spot.
You're blowing the toxic fumes into your garden?
How do you think chemistry labs depose of their toxic fumes from the fume hood? That they'll condense all the fumes to a liquid and collect it?
No, but they usually aren't built in the middle of a garden.
The plants in the backyard are sure going to like it (and so are the neighbors) :D
my toilet is a fume box after i have a dump
Username checks out.
Cool DIY Cody. Reminds me of my Grandfather making an elevator at his cabin.
Not going to go with the trolls and say what's wrong, but make a suggestion on the door.
Convert the door to a casement window type setup. Put some pulleys on the top and counter weights. That way it won't accidentally slam down on your hands some day.
im guessing you released this to patreons first, since im seeing comments from 9 hours ago but youtube says you uploaded the video 55 seconds ago
Stefan Nilsson that’s what I’m thinking, confused the f out of me at first
Stefan Nilsson TH-cam is probably drunk again.
Hahaha that's why we are patreons
I would use patreon but then I'd be poor. All the creators I want to support... there are like 20 of them.
If they invent a way for me to make a weekly payment and it gets split between all the creators i want it to then I will consider it.
I do what I can and turn off adblock for the creators I think deserve it.
cody releases most videos early to people who pay any amount on patreon
Finally some basic safty cody. That makes me happy. One idea to make you enjoy your creation longer. If this seal creates itselfe you will end up with scratches if you move the screen when the fan is on. You could put something soft there :-)
Are you sure you want a toxic waste outflow into your veg garden ?
Moderately cool though.
Cool build Cody!
Seems there are many knowledgeable people in the comments section.
I don’t claim to be anything special but I’m impressed with your build, it’s basic enough to encourage others to try constructing their own if they are carrying out similar backroom mad scientist things!!
Keep up the great work
Charlie UK
Can you get a different light? The white balance is way off with that one
Michael Andersen
I’ll look for something better.
BigClive says cob led chips are dirtcheap on ebay right now. I think he used the phrase "awash with them".
See his video from today entitled "Testing a large LED COB"
just use something like an ordinary warm white LED bulb which gives a nice soft yellowish glow aswell instead of the intense of just pure white.
@Mark incandescent bulbs don't flicker at all, the filament doesn't have time to cool down in between voltage peaks. And some cheap fluorescent fittings don't use a high frequency ballast, instead having a transformer type ballast which runs at mains frequency and do flicker.
Cody, excellent project. You could add a nederman arm to get the intake right over the target. Just watched for vortices/eddies in areas of the cabinet that accumulate fumes that might be released when you switch off the extractor.
One question: Whenever you do anything now, do you naturally want to film yourself? i'm not there yet but I'm starting :)
What about your plants outside the window they will be contaminated with whatever your pomping out.
Kristyanna Virgona well as long as the fumes are heavier than air (which it would almost have to be since it flows up through the vent) they won't reach the plants. But it should still probably be filtered as he said he would
In this case, the plants LOVE the nitrogen :)
you could use a welding fume extractor... these things are very high power and can filter out lots of bad stuff already out of the box, so you won't have to modify them as much as lets say a cooking fume extractor or something
Is that the proper way of saying "Cody's gas chamber"?
Hey Cody, I would suggest you mount the power strip outside to limit it's exposure to potentially corrosive fumes. It might also be nice to put in a variac or dedicated speed controller for the fan.
My favorite channel. Inspired me to open a channel
please be careful if your starting chemistry or using it as a hobby please do things with passion and knowledge and not intent for money or fame, some things can be very dangerous without the full care of common sense. fumes and vapors can be dangerous to health when unseen or unknown. but good luck just make sure you know what you are doing and dont try things just because others have.
Thanks. It's actually my passion and I'm a student of school class 12
