Fade in fan

Hi! This might seem like an odd question but I need a fan to "fade in" for an art project I'm working on. That is I need a circuit that makes the fan spin up slowly to full revs. Is it possible to build some simple circuit that can manage this task? And if so is the case could someone please send me a plan for it? The fan is a standard CPU-fan (12V). Thanks for your support!

Banging Fan

For some reason the central heating/cooling fan is making a banging noise. I know it is the fan because when it kicks on, I start hearing a banging noise. It like bangs 4 times a second.  Does this mean I need a new fan or can it be repaired? Also is this a motor problem or a problem with the fan wheel? It sounds like hitting an air duct with your fingernails.

Antique Fan

Hi, I bought an old Hunter antique fan at a garage sale  that I am trying to make work. I should mention that I am a 65-year-old female and have never done this sort of thing before. I have removed the cage and blade.    Through another source which has stopped helping me, I was able to unlock and de-grease the oil box. I did rewire the main cord and I see that the fan does work.  Yay!!!! Now the problems start.  There is a 3-wire cord that comes out of the motor head and  snakes down to inside the base.  This cord is majorly frayed.   It is not like the 2-wire cord I fixed that plugged into the wall outlet. I need some advice on how to replace the portion of the cord that shows the fray for both esthetic and safety reasons.  It is wired inside the motor and I don't want to remove that attachment.   I have enough wiggle room with the cord to add/replace a portion and snake it down to the base. I will attach some pictures to try and clarify my ramblings.

Experiment on whether and when a stuck up fan will break into flame.

Let us consider a typical home electric fan, and we put some obstacle to prevent the fan propeller from turning, then we switch on the fan on the fastest speed; will the fan and when eventually break into flame because the propeller cannot rotate?

PC Fan help?

Hi! Got a Dell 8600 Inspiron When I boot, the fan briefly turns twice. Begins to start, but stops abruptly. Doesn't do anything else. I think the fan needs to be replaced, but if it is faulty, why is it able to start briefly? I noticed this b/c it was getting very hot and I noticed a very very very faint beeping sound coming from around the area of the fan. Random beeping, no pattern to it.  Any advice/suggestions appreciated. Thanks!

CEILING FAN REPAIR

This could become an instructable, but these days, juggling photo files from cell phone to email to comp to ibles is so dang cumbersome..    anyway, this is how i fixed ceiling fan. fan has a rubber plate between motor and blades. apparently a bit of wiggle room for blades is a desirable thing. but that rubber plate was cracking. the fan blades had begun to hang low and drag against the light fixture below em. so i removed the lights that hang below fan. removed all 5blades,  blasted dust off rubber plate with compressed air, and used used gel superglue from loctite brand to glue cracks in rubber plate. i specifically got glue in a tube, not a bottle, since ihad to apply it upwards.  i never removed fan motor from ceiling, so, the work was overhead. the glue says its good for rubber, and so far, it has held up. the fan is reassembled, and working again.

Wall of case fans?

Hey guys, I have been thinking up ideas all night for wind power. I've been messing around with a decent dc motor I found in a printer, but I'll have to wait till tommorow to make some kind of proper blades for it. I however, have an interesting idea. I was thinking of using just one case fan by itself to generate power (see video below). But then I got to thinking, what if I made a wall of case fans in my back yard? and wired them all up in parallel or something. I measured the output of one case fan I have here and at most I could get was 0.100v DC turning it by hand as fast as I could. I come along so many case fans and throw them out all the time, so why not re-use them?? I'm not sure winter time would be the best time to put something like that out, but I think it would work.

Laptop Fan Buzzing? Answered

Hello Everyone, Need some advice here. I have noticed a slight buzzing sound in my fancy gaming laptop's fan recently. Its only audible when the fan is on its highest speed and then you wouldn't notice it if your volume is up. I'm fairly certain the problem is that the fan is slightly off balance. Here's why: 1). I completely dismantled the laptop and cleaned it of all dust and particles, so its not clogged or impeded in any way. 2). The sound stops if you tilt the laptop approx 30 degrees in any direction. (The sound actually gets louder until the 30 degrees is reached, then it completely stops). My question is: What should I do about it? Is it really much of a problem? Do I need to replace it? If I do, my warranty literally expired 1 week 1/2 ago, is there anything I can do about that? I feel cheated by the timing personally.

Idea

Hi, I have an idea that I want to see come into fruition. I have the general idea of it figured out in my head, yet the lack of knowledge in key areas, and other projects, prevents me from completing it, although I would love to see it built. It goes as follows,    By using the power of mice, construct an apparatus that functions in either one of two ways. The first way would use an exercise wheel (bought, or made) with magnets attached that would in turn power a fan in a column that would suck the air from the bottom of the enclosure to the top through a filter. I'm not sure how magnets work, but I know that they're used to create current which is what is needed. The second method would employ 3d printed gears to crank the fan round and round. Both would be made with a series of tubes, much like the internet, that would make it suck more. :]

Wall of PC Case Fans?

Hello guys, sorry if this is the wrong section but, I was thinking of making a DIY fan out of PC case fans to keep myself cool in the summer. I've tried a number of fans in the past, but they don't seems to be very good. I usually put them right next to an open window to draw cold air in. I was thinking of making some kind of rig like in the video below, only without the bitcoin mining computer. I got the idea from this video and from when I was messing around with the fans in my own PC. I was chancing the speed of the fan for the PCI cards and noticed that it could get really cold if ramped up a bit. ) I was thinking of using 9 identical 120mm or 140mm fans, preferably ones that can be used with a fan controller. Here is a few of the things I need help with. How will I power the whole thing? What kind of cabled will I need? Could I use a fan controller to power all 9 fans? Can I even hook up 9 fans to a fan controller? Maybe I could use 2 fan controllers or something? What brand of fans should I use? How will I attach the fans together? Cable ties like in the video? Maybe I could make a makeshift wooden stand to hold them upright.

How can I power my fans externally?

Hi, I'm trying to run my 12v DC fans externally. Is there a way to do this? Is there such thing as a power supply specifically for 12v fans? I'm thinking the only way to do this is to cut up a 12v power supply that I can get from the shops. Is there another way to power them? Is there anything that can externally supply the correct voltage (12v) to these fans? Thanks, really appreciate any help.

Ventilation In A Small Forge?

Hi all, Im trying to build a small forge in my small tin shed (9'x11') , due to noise and residential location everything must be inside and the sound proofing makes it pretty airtight, therefore I'm relying 110% on good ventilation design to avoid CO poisoning. The coke forge is in and flued using the side sucker design and 12" insulated duct, so far this works well with the addition of incoming air from the rear of the shop and I have been able to use reasonable quality test equipment to measure CO at acceptable levels (only under ideal conditions, further testing to follow). I have also thought of adding a propane forge (only one forge be used at any one time) but worry about the increased levels of CO produced, I have toyed with the idea of a hood which encompasses the mouth of the forge which would be ducted at 45 degrees into the main stack for the other forge (I would like to minimise roof penetrations if possible) I have made a rough sketch (in paint sorry) to demonstrate what I mean, do you think a fanned draught inducer is necessary/useful, we don't use them much in the UK so im not sure how much draught they induce :),  is the flue angle/ bends going to reduce efficiency greatly and would adding a fan to the intake to change to positive pressure internally make that much difference?  Any other ventilation advise would be greatly appreciated, including anything to help understand the maths required to calculate correct air volumes etc, I'm fairly serious about doing this correctly, understand in some detail the dangers of CO exposure and would not concider continuing without thorough testing for safety. Thanks in advance, drawing not even slightly to scale :)
