Covering up computer vents?

My computer has these vents on the case that are blowing out cold air while my expansion slot vent is blowing out VERY hot air. I was thinking I could cover up the vents that are blowing out the cold air which is very cold so I could make the inside of my comp cold so my video card doesn't get as hot. Is this a good idea?

Need help in cleaning dryer vent run

I need help in figuring out a way to clean the build-up in my dryer vent run. The run is in a crawl space and approximately 25 feet long. I have been unable to find anything available to run through it to clean the lint buildup. Thanks in advance for any viable suggestions.

Help Replace Discontinued Range Hood Vent Fan Switch

The variable speed fan control on my Thermador HT48HQS hood vent does not work and the replacement switch is no longer available.  I'm looking for some help in making a new switch.  The Thermador VTR1000Q motor is mounted on the roof and controlled at the hood with a variable speed control knob. The motor is rated at 115V 60Mz 7.8 Amps. Photos of the switch assembly are attached. From what I understand, the speed control knob is a potentiometer that regulates the speed by proving a range of amps from 2.5 to 8? If I could make a variable speed control that would be great.  But I'd be more than happy to have create an on/off toggle switch or a toggle for low on/off high.  Can anyone help me?

How Would I Make A Light-Proof Air Vent, Please?

Hi - thanks for stopping by. I am in the process of making a dark-room for my photography. It is stuffy in there and I have an air-vent which lets in light. I would like to make a cardboard box (or something) that I can put over the air-vent so that air can flow freely but will still not allow light to venture through. I would appreciate anyone with any ideas please ;-) regards Kevin

Help Needed with Clogged Air Vent Drain Pipe and ? on Dishwasher Drain Pipe

I need help and learning how to remove, de-clog, etc. The picture is my kitchen sink drain area.  I have two-sink with the right side having a garbage disposal, with connecting pipes leading out.  But then, I have another pipe leading out in the same direction, but it serving as an air vent pipe.  There's a cooper pipe leading up and into the air vent pipe. Prior to taking the picture, my dishwasher's drainage pipe was connected to the bottom of the cooper pipe.  Well, last night I've noticed my sinks were clogged, I ran the garbage disposal, and then the a gush of garbage water came out of the under sink cabinet. Well, after a lot of cleaning, this morning I removed the drainage pipe from the sinks, and noticed that my air vent pipe was gushing out the garbage water. After searching the internet, it's rare to have a clogged air vent, but at the same time, no one seems to install the dishwasher drainage pipe into the air vent pipe. So my questions are: 1) Should my dishwasher drainage pipe be connected to the upper part of the garbage disposal?  (You can see there's a fitting on the disposal right above the white PVC pipe leading out of the disposal.) 2) Why would they (the original builders) install the dishwasher drain pipe into the air vent pipe? 3) Most importantly, how do I go about in unclogging the air vent pipe?  (It's all bonded together versus having a washers and nuts or a threaded union.) 4) Any answers and questions that I don't know what to ask?  Insights/suggestions? Please and thank you. v/r Bobby

Pesky cat and warm air heating sensor

Hi, My dear little cat takes great pleasure in warming her butt on our warm air vents. I was wondering if someone could help me design/build a little sensor that I could place on each warm air vent. It would need to look inconspicuous and keep the cat away from the vent (vibrate or buzz when she approaches? - dunno, you suggest). Thanks! G

Plexiglass Temporary Window

Hi folks.   I'm designing a vent that will vent outside using a vent inside a plexiglass window.  I don't know how to mount the sheet inside my chosen window.  It's a modern window that has a screw type mechanism that takes the window away.  I took the screen out, which just clips in, and expect to do something similar for the plexiglass item. I looked at some of the hardware available at Home Depot and couldn't find anything that would make this thing work.   If anybody has any ideas, that would be great.   Some pics

Replacing a propane stove with a wood stove --HELP NEEDED

I need to remove a propane heating stove and install a woodstove that I already own. I'd like to install the woodstove in the same spot as where the propane stove sat and I'd llke to use the same venting pipe if possible. The problem that I see is that the propane stove uses a 4.5" vent pipe off the back of the stove and it continues to be 4.5" pipe as far up the chimney as I can see (only a foot or two) also, the propane vent pipe is thin, flexible aluminum pipe that goes up the inside of the chimney, while the woodstove connecting pipe is 6". I don't know if the woodstove can be used with 4.5" flex vent pipe from the propane stove or if it needs bigger, steel pipe for wood fires. Does anyone know? Thanks. Peter Norwell, MA

Want to use a pet door as garage vent.

I am a renter and have a 2 car garage with a pet door in between. The garage stays pretty hot even with a fan running. I needed to vent some of this hot air. I thought I could take a box fan and design some sort of ducting to allow the hot air to be sucked out and cooler air in and also prevent the pets from escaping. I figured I could remove the plastic grill and attaching the duct to the screw holes left from the grill removal. Not so great with geometry but needed to slope the duct box doen to the rectangular shape of the pet door. Any thoughts?

Clay Contest Criteria

I have a question about the Clay contest criteria....debating whether to do an instructable for a DIY downdraft kiln vent for under $50 (cf $450-600 to buy) that I built. I've actually been waiting for the clay contest before publishing, however the contest criteria says:  "For the purpose of this contest, any project that uses a moldable, malleable, clay-like product will be eligible." So question is, would a kiln vent be eligible? Previous contest criteria has been "all things" related to said topic, but this seems more narrow in scope. Obviously a kiln vent is not made with clay, but it certainly fits the pottery topic. What to the contest gurus say?

Mold venting for lost foam metal casting

I've been casting small aluminum statues using the "lost Foam " technique. My success rate has been about 60%t070%because of the aluminum freezing in the long narrow parts of the mold. The statues are human figures so the outstretched arms and legs sometimes are not complete. Am now considering heating the mold to reduce this problem. Any suggestions will be appreciated

Thoughts for a fan for venting a homemade 3D printer enclosure?

Hello all, I'm in the early stages of building my own enclosure for my 3D printer. I'm going the route of building it using Ikea Lack tables. I'd very much like to put in a fan to vent the fumes from printing out the window via a hose. Originally, I was going to use a USB fan, but I'm starting to wonder if that will move enough air to make any difference. I was going to go with USB because I have no electrical work skills. I'm curious if any of you have thoughts, or have already come up with solutions for this. I'd be interested to hear any suggestions or advice anyone has. Thanks!

cooker hood condenser

Ok i have moved into a new studio which does not have an external vent fitted to the cooker hood and relies on a re-circulation kit comprising of a small tower and a disposable carbon filter (which can cost quite a bit to keep replacing). So what i was thinking was how about ducting it to a homemade condenser, something simple like a plastic container with a cut off of hood filter attached to an area near the top of the container and the vent ducted in through the top of the container it could be primed with an inch or so of water to get the process going..... i recon my concept is pretty basic but am i heading in the right direction?

Apartment Wind Turbine ideas

Hey all. I would like to gather opinions on 2 small wind turbines I'm thinking of constructing. Difficulty: I live in a third floor apartment (it's also the top floor). My first idea was to modify an old box fan and mount it outside my window. Then I walked into my bathroom, which has a noisy exhaust fan in it. I accidentally turned it on and realized that I could build a collapsable darrieus turbine that would fit up the exhaust vent, expand when outside, and hook that up to the exhaust fan motor already in the vent. Does this sound feasable? My goal is to see if I could charge a cell phone from the power generated by one of these two options. apologies for the quick-n-dirty sketch below.

Butane recovery

I have instructions for extracting pure essential oil from plant material using butane. The problem I have with it is that at the end, the butane is vented. I just don't feel right about venting unburned hydrocarbons into the atmosphere. I've been looking at glass lab equipment (distillation tubes, connectors, etc). I have no background in chemistry, but it seems to me it shouldn't be too difficult to put something together using standard glass lab equipment to capture, distill and reuse the butane. Butane boils at 31 degrees Fahrenheit and is heavier than air. At the end of the process, the oil is scraped from the bottom of a drying dish. Does anyone have any suggestions on how to put something like this together? Thanks

How make round 5" air duct valves?

We moved into a large (for us) house, and we only use a few rooms. I managed to repair the furnace, but the first bill was astronomical. Beyond the leaking windows and lack of insulation, the problem is that, as it is, we have to heat the whole house. I've discovered a temporary method of blocking vent tubes to unused rooms (by stuffing the tube with a rag), but I want real valves. I've heard they are called air duct dampers.  My vents are on the ceiling aimed down.   So, I've seen these check-valve 5" ones https://goo.gl/8zRGLX but I haven't found any that would open and close manually.  But this doesn't seem like it would be difficult to make. I'm toying with the idea of using a cone-shaped "lid" with some kind of springy cord holding it in. Does anybody have any ideas?  How do I make a manual (or electrical solenoid, I suppose) operated valve for a 5-inch round air duct?

selective room heating?

I just turned on the heat before going into my room to go to bed. My roommate and I are in about one fourth of the whole house (and will be for about six hours), yet every room is being heated. This seems like a huge efficiency problem. Are there commercial systems out there that can heat selective rooms? If not, are there ways of making such a system? Can I just tape cardboard over the vents?

Rainbow vac for dremmeling?

Is this a good idea or no? I'm sure a few people on here know what a rainbow vac is, and it has the suction to work (although I try to use the low-speed mode if I can because it's a loud vacuum). I emptied it today however and there was metallic crap EVERYWHERE on the inside of the bowl. It wasn't that bad actually and washed out with water. But I was wondering, should I maybe use something like some dryer vent and make a plate to fit into my window?

Can Anybody Top this Crazy Green Idea?

What is it? it's the side view of a solar peaking plant. With PV panels on the roof of a giant structure that would produce liquid air during periods of low demand, and augmented by solar work like a big energy storehouse that would be called upon during peak demand. During peak demand the liquid air would be vented into the atmosphere, causing it to snow in the desert in the summer.  It could also cause the formation of a permanent snowpack downwind of its' location.

New water heater

Oh please help me decide( and more importantly convince my buzz word influenced wife), I want to replace my current hot water heater, there's nothing wrong with the current one other than being 18 years old, meaning it's a ticking time bomb waiting to flood my house. So anyways, the local gas concern has partnered with local contracters Tankless install $25 a month of 60 months, minimum spec heater, does not include expensive, required stainless steel venting. $450 rebate Tank heater 40 gallon install $10 a month sixty months, includes venting $350 rebate Now the no brainer, my gas bill is averaged at $41 a month, $30 is actual gas charges, Now, the tankless claims to save "up to 50%" which is marketing speak for "does not save 50%" but let's say it does, I would save $15 a month, the difference between the cost of the tankless versus the tank, so it would be 54 months before I started saving money. And since we plan on "upgrading" to a new house before five years (when I've graduated), I will never see those savings. Guess I really should get the tank heater, what do you think?

Regulating a Spark

I need to build a unit capable of supplying a timed spark. At approx 1 sec intervals. The unit will need to be small/cheap to build and be able to supply current as to generate a timed spark across two electrodes via 240v power supply. The unit I am attempting to build is a flammable gas warning/ignition device. The purpose of it is to ignite the first immediate gas detected, as to avoid a larger detination later. The unit will be made of machined aluminum. It will consist of a vapour detector hooked to a fan unit, which inturn vents the gas to the ignition device. Thus igniting the gas. At the moment I am working on the ignition system, hence the question. Thanks for any help.

How to drill a 4 inch hole in concrete

The walls at our new place are 6 inch thick concrete (it's an old Naval base) and we needed a few holes for vents. I've hammer-drilled through concrete to sink anchors, but a 4 inch diameter hole is a little intimidating -- until you have the right tool. Here's a few pictures of the right tool. I only watched, so I don't know the finer details, but I thought people would appreciate just seeing the tool. The work flow went something like this: 1) hammer-drill and sink anchor to attach machine to wall 2) turn on machine; insert earplugs 3) wait It took quite a while, and that drilling noise reverberated throughout the whole place!

They start ranting and raving and just generally displaying a ridiculous amount of anger (and then calling the ones who *are* pro bad things...). I mean, I can understand strong reactions, I wasn't precisely as happy as a clam about it when the announcement came, far from it, but at least I had the excuse of not having a couple months worth of discussion, replies and explanations from the staff and owners to look at. >breathes<Anyone else getting sick of seeing all the disgruntled people stomping around yelling about their rights to have everything, for free, forever? :( I'm so tired of typing the same replies to the same complaints and questions...

Project in mind. Need ideas for simplicity.

I have a project in mind. I have children with a pet cat. I intend to build a charcoal filtering for a catbox/cat tree I am building. I want to use an alarm clock (easy to adjust time if needed) to activate maybe a buzzer and flashing light daily for box cleaning. The fan runs at a low speed constantly at the top of a vent tube to keep the smell controlled.  I want an input to reset the buzzer/flashing light when the drawer with the litter box is opened. I have no idea how to build the circuit. I tested the filter system on a mockup box. It works fine cat doesn't notice the fan. (its 3ft up a 3" piece of PVC). The lack of smell is the reason I'll need a reminder. I could purchase an industrial programmable relay but cost is a huge factor and buying an added power supply etc for control voltage adds up. I have an industrial electrical background and no problem working with small circuitry but have never designed anything so hints and help will be appreciated.

Cool Misty Morning Simulation

Here's an idea: Yesterday I was out on my motorcycle and it started to drizzle or mist very lightly. Helmet starts fogging so I open all the vents. The cool, clean and misty air rushing through the helmet was like a sort of inner piece. Like those mountain mornings or early fall mornings by the lake. Just gave a great feeling and I instantly felt refreshed and energetic. Anybody have an idea for recreating this feeling in a small space, say 10 x 10 room. I do have a cool mist humidifier for when I am sick but it is not nearly the same feeling. I've tried searching for some sort of product but have come up mostly empty handed and imagine it would be rather pricey anyways. Examples of said feeling: http://2.bp.blogspot.com/-STNHl9kfFc8/TYmDflagaUI/AAAAAAAADPA/fbkHM6FQttQ/s1600/Morning%2BFog.jpg http://www.sticksite.com/blog-2010/foggy.jpg http://upload.wikimedia.org/wikipedia/commons/c/c3/Misty_morning.jpg If you have a thought or idea I thank you plenty!!

12v to 120v sine inverter boosting

I have a 20 year old van. The a/c leaked and it is much cheaper to buy a 120v window unit ($140 with a 3-year walk-in exchange warranty) than to pay a shop to rebuilt the vehicle a/c. I chose a 5k BTU window unit that uses 4.1 amps running, and have a 1k watt sine wave inverter. Alone, the inverter will not start the a/c unit, but will power the fan. I confirmed a trick to start motors with an inverter. I connected an 8" bench grinder to the inverter and started it. It took a few restarts to get it up to speed. Then I started the a/c and it ran without problems. The bench grinder motor was able to supply the reactive power the a/c compressor needed to start. Both continued to run without straining the van's alternator. BUT, I don't want to travel with a running bench grinder going, that's not safe. Is there another way to supply the reactive boost that is safe to travel with? Once I get a simple stable way to run the a/c I'll work on a mount to vent the hot side. The van has sliding windows.

Is silican dioxide/diaiomaceous earth safe in energized electronics

One of the problems with bringing found items home,is bugs that live inside.  i think the powder use for crawling buggers  is the safest i know of, I sprayed a couple items with the powder after i saw a big water-bug zip across the floor. Since i also had a acme juicer on the floor near where it exited, i sprayed that to with the silican dioxide/diaiomaceous earth mix, i may give it to a friend and dont  want to give her a roach problem. I also dont want it laying eggs inside. i doubt it went into the juicer,but better be safe. i was thinking of spraying everything i find  through the vent wholes so i dont release anytthing  into my apartment.  I did that one time when i took an A?C out of the window and lreplaced it.  i let the old one sit on the floor for aq couple days.  I had yellow jackets the whole summer  in here.

DIY Home Insulation

So I know I need to better insulate my attic for the coming winter but, money is tight and the to-do list is growing so I began thinking of alternative or DIY materials to do the job. I know Cellulose insulation is shredded newsprint treated with chemicals to make it mold and creature resistant, and on a small scale maybe that process could be a fun experiment, but not for 1000 sq ft. My next thought (and current favorite) is to acquire styrofoam packing material (box inserts, packing peanuts, un-used food and drink containers) and mill them up to about the in to some uniform size. Then get some cheap plastic bag/ tube material and fill strips with a couple of inches of styrofoam. Then the blanket o’ foam could just be laid out over the existing insulation in the attic. Now, before I start this endeavor I thought I would check with the instuctable think tank to figure out: A) any better ideas 2) what R rating a 3 inch loose fill blanket of styrofoam and plastic would have III) Is this a terrible idea due to moisture being trapped under the plastic Also in a previous forum someone suggested re-routing their dryer vent to the attic and I was wondering if anyone had tried that and/or anyone’s thoughts on that. -Odo

Wood Converted SWB Recumbent Bike of Awesome!

This is a project coming soon... But I'm so excited I have to share... I'm beside myself in excitement, in fact.All that's left to finish the project is:1. Recondition a bit more chain and add it on2. Add idlers and get my chain line in order3. Cut excess wood and make a SeatBut after I assembled a crank into some 2x4's - and had to step back and laugh. I've seen it before, in person at the maker faire. But to do it myself and see how easy/simple it is... Ha!So I cobbled that together - made a pseudo tie fighter handle bar from some scrap PVC and two Tees... And rode off into the sunset... Until the chain derailed - and then I realized I couldn't make appreciable low speed turns due to chain routing... Both problems can be fixed with an idler - a solution I've yet to install due to Kinematics homework having a due date of tomorrow.So yeah, this is something I've always wanted to do. And I'm totally happy I did it (and happy I bought those cheap bikes at auction last year :p). AND, the front boom is modular. I intend on making it, and have accommodated for, adjustable. So I can go for more incline and a more aggressive seat position. (mind you, this is a single speed :p).Okay, I'm done venting -- feedback?

Laptop Cooling Pad

I'm using a laptop-sized, vented, inverted vegetable tray to keep the laptop cool. It's quite effective even without any fans in this scorching heat. I added a CPU fan underneath ( 12 V, 0.42 A), and ran it off a USB cable from the laptop. The air is quite nice, but one thing I'm a bit worried is, when I touch the top of the laptop, it slightly vibrates constantly due to the fan underneath. Is that dangerous for the laptop? I'm planning to add another fan beneath the hard disk. The one I have now, is under the laptop's CPU fan. Another thing I would like to know is that, is it okay to run two fans of 042 A each, from two USB ports? Each USB port can supply 0.5 A max current. Running one fan off each port should be okay? But, today, the temperature was quite high in the afternoon, nearly 50 degrees! I'm thinking of buyin a readymade laptop cooler.  One of these three cheap ones at ebay India: http://cgi.ebay.in/Folding-Chill-Pad-Stand-Laptop-Cooler-Cooling-2-Fan-/250631119144?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item3a5ac76128 http://cgi.ebay.in/Chill-Pad-Stand-Laptop-Cooler-3-Fans-USB-Fan-LED-Light-/250629679857?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item3a5ab16af1#shId http://cgi.ebay.in/New-Super-Mini-2-Fan-Foldable-Laptop-Cooling-Cooler-Pad-/280504780978?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item414f6348b2 Please advise / comment.

box(es) for sub(s)?? How many? What size? Here's some measurements.

So... Got some subs I had lying around: http://www.crutchfield.com/p_500SWE1042/Alpine-SWE-1042.html?tp=111&tab;=features_and_specs I am trying to figure out if I should vent (I don't think I should from research) and if I can do them in a single box or if it's better to put them each in a box. I also haven't found out if I should JUST double the volume for having both in one box or if it should be a different amount. The suggested volume I've calculated is 4.1 cu ft (but that seems a bit huge).       V(as) 33 liters   |    Q(ts) 0.66    |    10 Inch The speakers will be in series, I don't know if this affects whether or not I can put them in a single box. How much does the shape of the box matter? Can I make a rectangular cube and put the speakers at either end or do they need to be on the same side? When it comes to fill would it be better to use something fluffy that takes up a large amount of space like very fluffed out cotton or is carpet always the better way to go? I cannot find how much fill I SHOULD use. I have found suggestions for just carpet on the back wall and some for all sides wherever you can and even two people suggested to fill it to about 80% (though it did not say what with). Any questions?

Loudspeaker design advice needed. Mini-array Viston FR10 drivers

Hi all, I'm about to get started on my first set of loudspeaker cabinets. Since quite some time I have 8 Visaton FR10 drivers lying on a shelf and I want to use those. After some research on diy loudspeaker cabinets I came up with the design in the attached drawing. Before I start building a pair of these, I'd like to have some advice on the design. I'd like to keep the costs as low as reasonably possible :). Questions I have and some design considerations: - Are the tubes correctly dimensioned? I used the "vented box calculator" over here to get the dimensions for a cabinet with one driver. I doubled the area of the tube and placed two of them in the cabinet. - I plan to clad the inner walls and the backside of the drivers' frame with convoluted foam. Do I need to fill the inner volume with some kind of polyester wool as well? - I want to use the speakers with my "Serious Amp". Will that work? - I planning to build the speakers without a filter. Is that wise? - The four drivers in each cabinet are in pairs series // parallel, to get a joint impedance of 8 Ohm. - As I understand it from the various forums / websites, it's best to place the drivers in a vertical line. However, the cabinet becomes too tall to fit in my tiny livingroom. I just don't have the floorspace to place them. Am I going to regret that decision? Your advice is appreciated! Y.

Heating Control

I have been thinking for some years now that I would like to have finer control over my central heating. The problem Now we are older we feel the cold more so in winter the heating is on all the time. This means that we have to keep altering the thermostat on each radiator at different times of the day or just leave them and so waste energy. One method means wasting energy but the other means rooms will be colder than we want initially.   The system and what i have We have a combination boiler which has a digital timer and also on the panel are temperature controls for hot water and radiator temperature. Each radiator has a thermostatic valve so each room can have it's temperature set independently. I have a computer which runs 24/7 and also a bit whacker which I can control via python code and electronics has been a hobby for over 50 years My idea I would like to have some system which would allow me to adjust each room temperature via computer control.   Possible solutions Solution 1 Fit a stepper motor to each thermostatic valve to adjust it at different times of the day/night. This would allow precise control but would be quite expensive to set up. Solution 2 Fit a small structure round each valve with a filament bulb or resistance wire in the bottom so that when power is applied to it then the temperature around the valve will rise and so the valve will close or, at least partially close. I think this would be much cheaper to implement but would have the small on-going cost of using power to the bulbs whenever the room temperature needs to be cooler that it would normally be. My initial plan Build a small structure around one of the valves with a low voltage bulb in it. It would have vents at top and bottom and so air would circulate. I have a portable digital thermometer so i could gather information and try different bulbs to see how much power would be needed and therefore what the on-going cost would be. Also try various shapes of structure to see what the effect would be.   So guys what do you think?
