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!

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.

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.

Using a fan to drive another fan

Hi all, This may very well be a stupid question but after a quick bit of searching I cannot find an answer (which probably means it is stupid). I have been thinking about setting up a wind turbine to generate some electricity for my home. It occurred to my that it would be good if the wind turbine did not rely solely on the wind from outside so I started thinking about using another fan to blow air into the fan or fan used to create the electricity. Does anyone know if this is possible? I guess what would be ideal is if fan A was powered by the electricity produced by fan B but fan B also produced a little extra electricity that I could syphon off. This could then easily scale up to produce more power. [ fan A ] ~~~~~> [ fan B ] ~~~~~> electricity I suppose if fan A takes more energy to run than fan B can create then it won't work. Has anyone looked into this?

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.

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!

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.

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.

Is it good idea to replace laptop's fan by fan of cooler pad ?

There are nasty fan inside of my laptop. The fan is loud and sound is nasty and works always (its such model of laptop), so I want to remove bottom of the laptop's corpus and may be top of the cooling pad and use the pad instead of internal cooler (which I will plug out). I have AMD. I think that it's may work because: fan inside laptop blows at radiator (which is on another end of copper pipe), not right at place where processors located. And I want big fan that will blow right at those part of cooling system where processors located. I'm not gonna remove copper pipe, just plug out default fan and use pad's instead so that it will blow at cooling system from the bottom. I'm gonna use pad with 220-250 mm fan. What do you think ?

Replacing an old bathroom fan

This is an idea someone may be able to use, but it does not quite rise to what I would want to do as an Instructable. A widow friend has two bathrooms, each with a very dated bathroom fan in need of replacement. I was able to mount the works (fan motor, fan blade, and mounting plate) for the new fan onto the old mounting plate after modifying the old plate. This saved me hours of work in a very hot confined attic when time and tools available to me were quite limited. Had I torn out the carcass for the old fan and tried to put the new fan carcass in its place, I would have needed to fashion a wooden framework for mounting the carcass that would fit just right between the ceiling joists, all so the fan would be properly centered above the existing hole in the ceiling.  The mounting plate for the new works was just a bit smaller than that for the old works. The height and diameter of the new fan cage were very close to the dimensions of the old fan cage. I began by using a cutting wheel on an angle head grinder to cut through the old mounting plate around the circumference of the old fan cage. Then I positioned the old mounting plate over the new works and its mounting plate. The glass dish that would cover the light bulbs fastens to a shaft that screws onto a threaded stud centered between the corners of the new mounting plate. I sighted across the corners of the mounting plates so the threaded stud was centered. I clamped the two mounting plates together and drilled four holes for 10-32 screws 1/2 inch long and secured them with nuts and lockwashers. (I did need to cut out part of the new mounting plate so the fitting for the two electrical outlets [fan and light] were accessible to plug in both the light and fan cords.) Had the glass dish mounted to the works differently, I would have used measurements from at least two sides to the center of the fan's shaft to position the new mounting plate on the old. Once the two mounting plates were held together with four screws it was a simple matter to put the works into the old carcass and plug in both the fan and the light to their respective receptacles. There was no question the works would fit because they were attached to the old mounting plate that had been taken from the old carcass. The round opening in the ceiling drywall bordered on being too large to be covered by the escutcheon for the new cover/light fixture. I added some drywall spackling around the edges to close any imperfections and gaps. For me this was an idea that worked and saved me a lot of time.

Laptop Fan voltage booster

Hi, my laptop is overheating because the fan isnt fast enough. My idea is to build a small voltage booster to increase the fan voltage a small bit. It will be overvolting the 5v fan but i dont mind. For example, when idleing, fan voltage is at 3.5v and at full load its at 5v and i would like it to be 1-2v higher at both points WHILE still maintaining the variable control (spinning faster and slower as needed) Problem is, im pretty good at soldering but i dont know how to make one. Could anyone help with this project Thanks
