Step 1: what you need

motor, (port USB = max. 2,5W !) 2 Cd, USB cable, papier or plastic tube

Step 2: Windmill

Cut and form CD or DVD

Step 3: Cable

Prepare USB cable, leav: red and black

Step 4: Folding


Step 5: Finish

i cut a little material out from in between each fan blade to give it some room to suck some air in and it prevented it from fracturing when bending it over the flame. here's a picture of what it looks like,
this looks good..<br>i think making fan in this way is better
im making a fan like urs but im useing some plastic from a beading box i found at my houst it is approximly 2inches and im useing a moter from a portable cd player its a little small and loud bit it works
hello,<br><br>can some help me?!<br>how to make the cd past in that angle?<br>did you remove them and atacht them again with glue?<br><br>bb
I once saw a method where you cut the CD as shown above and then you can heat the part where the cuts meet and then just gently twist the blades :)
are u german?<br>
nice fan i am definitely going to make one while its summer here :D
What's the orange thing in the 2nd pic.?
it's just a connector, wires get put in both sides and the screws lock them in place
&nbsp;i've done make this cool fan,.. thank you,...
where would i get the small motor?? from a old tape radio? im still not sure how you do the wiring and if you really need to solder it... im stll a beginner
radioshack has a bunch of them for $3 to $5 and something like a tape player or old hairdryer or something like that would work
god dammit i wish we had radio shack in the uk
i wish we had one too! :)
Me too. Next best thing is Maplin for high street components, but they are expensive and no where near as common as Radioshack. My nearest is brighton, 13 miles away. a 20 min train journey to buy a resistor, not gunna happen.
lol yea maplins is a bloody rip-off, i just get what i need from my DT department at lunch break when there's no-one around, not a very big choice though, switches, leds, and motors nothing special.
Is there any easier way to cut the cd? because every time i tried, it kept fracturing, making that blade worthless.
u can use a scicors....just use a sharp one....blunt ones make the CD crack
get someone to blow on it with a WARM NOT HOT hair dryer and cut it with scissors or watevr youve got....
Exacto knife
by using cutter,slowly cut it.the best way
thats really kool. where can i get a that little motor from though?
also if you have an old cd player, if you taek it apart, you can get a motor out of it that has a spot that lets the cd snap right in. it's the part that you actually put the cd onto.
oh yeh i broke open a old cd player that sukked and i found 2 or 3 motors, wire, switches, capcitors, and a lot of stuff
Yep. They're actually quite useful for electronics of all levels. The one i opened even had 2 audio connectors that i plan to use for an amplifier.
A dollar store car.
take apart an old r/c car
<pre>Radio Shaq, they sell them relatively cheaply</pre>
you could always get it from an old optical drive <a href="http://www.instructables.com/id/USB-Cooling-Fan-from-a-broken-drive/">http://www.instructables.com/id/USB-Cooling-Fan-from-a-broken-drive/</a><br/>
I just sttripped down a CDRW to see what usable parts I could find in it. For this project you'd likely have to use the tray transport motor, since both the head and disc drivers were stepper motors and need a specific pulse stream on 2or more sets of windings. Though a cheap stereo system (radio/tape/CD) I stripped a while ago had a regular DC motor for the disc instead of a stepper. You just have to see how they're connected (2 terminals are simple, just add DC).
It's only the CD writers will have a stepper, reader only just has to turn away so it's almost always DC motor...
erm... i did all exactly as it says in the guide but when i put my fan in usb, it works but my mouse turns off -.-
How are you supposed to bend the blades? I cut 8 sections but they won't stay angled after I bend them. Oh, and if you do this with CD-R's, you'll get flakes of shiny reflective paint everywhere.
Use the candle to melt the blades a little at the base
hi, what did you put in the cd hole? so you can glue it with the motor?
<pre>It looks to me like a cork </pre>
ok, thanks, i will try it
<pre>No Problem</pre>
<pre>Very nice, I like the way you think </pre>
I think i will make one of these but i will add a wire cage to it. Yea i like my fingers and knowing me i would accidently put something important behind it and it would be destroyed.
If you have knex, that whould be VERY simple
now I know what to do with the aol cds!
You mean MORE stuff to do with <a rel="nofollow" href="http://www.instructables.com/id/What-to-do-with-all-those-AOL-CD_s/">AOL cds</a><br/>
Yeah me and my friends used to go down to the park and whip em at each other or throw as frisbies. I think I left some down there... Oh well :D
What would happen if the system shirt-circuited? Would i ruin my motherboard? It's a nice idea, if it's 'Marinus Proof' i will make it.
More likely to burn that usb port of your motor out, chances of a motherboard failure are very low.
Sorry meant to be " More likely to burn that usb port OR your motor out " Sorry again
Be sure to test your motor to see which way it spins before bending the CD! You don't want it turning the wrong way. It won't do much good if you have it backwards :)
cant you just turn the cd around?
actually, in most circumstances no. Just reversing a blower doesn't make it into a sucker. Well, it would, but it would be very inefficient. In an actual fan there is more than just angled blades, there's also curvature and slope that aid in the collection and directing of air. Though in this case since the blades have no curvature or sloping, it would be ok to just turn it around, but then again, only one side of a cd looks shiney and cool.
