Supplying amperes on fan? Answered

Hey, I'm just wondering if I were to plug in two fans rated at 12V .1A to a 12V 1A power supply, would the extra .80A will overload out the fans? Or will the fans only draw what it will need? And for other simple devices like LEDs, will this apply?

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!

Bad idea to put fans in air duct? Answered

Im not sure what its called but the end of the air duct I guess. I wanted to put some computer fans in them and I wasnt sure if this was a bad idea. My rooms hot and the rest of the house isnt. I get cool air through there but doesnt come out far enough to get around the room, I figured if I put fans it would help and im not sure if fans in there is a bad idea. I already have a fan in my room but doesnt help.

How to build a motor reverser?

I have computer fans that I use as fume extractors when I solder. I would like to know if there is something that I could build to reverse the direction of the fans.  On a slightly related note, I have a netbook cooler with 2 fans in it. I have tried reversing the polarity but they won't spin the other way. Can someone help? There are no diodes in the circuit, I have checked. I think it's because the fans can only work if hooked up properly, can someone confirm?

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.

I am in Australia and I wish to wire in an exhaust fan to my fluro light operated by the one switch. Answered

The switch has a red wire and a white wire leading to the fluro light. The fluro has twin and earth (red, black and green) leading from a previous light in another room and another exiting to the next light in the house. The fan has two wires, a brown and a blue. I attempted to parallel the wiring by connecting the blue to red and brown to white. Once the fuse was turned on, the fan operated automatically and the light flickered without the switch being turned on. I reversed the wiring (brown to red and blue to white) with the same result. Logic failed me. Given that it is two wires on the fan (pos and neg I assume) I figure I am better parelleling to one of the twin and earths, but which one? Electricians charge a minimum of $240 per hour here, with a minimum of 1 hour charge, regardless of it being a 2 minute job. All connections are 240V. Wire joins will be completed using BP connectors.

how to modify a twin window fan for easy cleaning

Hi, I was given a twin window fan which works just fine but is dirty (dirt and a fair number of ex-gnats).  The manual is no help as it says to wipe the exterior with a damp cloth.  I thought it would be a simple job to just take out the 12 screws holding the two halves together but unfortunately the off-high-low levers (one on each side) are preventing me from separating the two halves.  I can't see any screws holding the lever mechanism in.  I tried rotating one side 90 degrees to see if I could slide the lever out through it's slot but it's too fat. I've had other twin window fans with the same set up and never could get them opened up.  It annoys me that the manufacturers make it so difficult to clean these fans.  I think a fair number of people have this problem and just give up as the local thrift store gets these fans in all the time.  I'm thinking of using my dremel with the cutting wheel and somehow slice off the lever knob.  It would mean we would have a shorter lever on one side but we can live with that.  The lever is kind of wobbly and I'm trying to figure out how to hold it steady without having my fingers so close to the cutting wheel. I know this is a really small problem but it really bugs me that something that should be so easy is difficult.. I'd appreciate any suggestions.

Simple LED question... if you know how to do the math!

A few years ago, I found a plastic pumpkin with a "faux flame" set up inside of it. I liked the idea of it and am trying to replicate it to make a few faux flame torches around my backyard for halloween this year. The idea is that there is a small 12v fan near the top of a tube. There two or three leds glued around the top of the tube. The fan blows a flame shaped piece of fabric up and the leds light it up to look like fire. (possible future instructable?) Unfortunately, I don't know much about circuits and the math of electricity. I found a small fan (12vdc .13a) and 2 red leds (2.6v). I hooked them up in parallel with a 12v 1amp wall wort coverter but nothing happens. I have done a little reading online and wonder about needing a resistor in front of the leds. I wanted to hook it up in parallel to get the fan to work at full speed to make the fabric really blow. From all the circuits I have seen online, this one seems really simple, if I knew what I was doing. Can anyone draw me up a simple diagram? What am I goofing up on here? Thanks! Matt
