i found a motor in my crappie cd player(acutually 2) and the one that moves the laser is the one i pulled out and it says on the sided/v 5.9...will the usb keyboard suffice for that power?

i read somewhere that a usb port can put out as much as 2 amps of power because the security setting of the ports is added to gether and only kicks in if the power of all the usb ports are excedded. also, the moter would probably run just fine on 5v if it wont fork over the extra power(but it probably will)

I saw an extremely good USB fan in a mag once. It was basically a 1 dollar fan, with a USB cable and a voltage regulator instead of the battery pack. It takes about 10 minutes to build and it works like a charm.

although it semi-defeats the purpose, you could also get a motor out of an old personal fan, in order 2 save u1rself some effort of making a an from scratch. Alternativler, there are lots of devices that have motors in them... ...133t.

It's good. You could do just as well with a decent motor, but the CD drive was a good idea.

I built one yesterday. I'd been playing around with building one for myself, and then my girlfriend told me she needed something to cool her off when sitting at her computer (she doesn't really have room for a full size fan). And so, I built this for her. Mine is a little different. I used 16-gauge wire for the support wire and wrapped it in electrical tape. I also took a normal CD and sanded down the outer side to give it a roughed in look, and sanded the edges so they were smooth (wasn't sure how hard it would be to stop or how quickly mine would spin). It was also my first "soirée" into soldering. So... thanks for the idea. I'm pretty sure she's gonna like it. So... again, thanks for the idea, and the opportunity to learn a skill I'll use for quite some time. GR
this has been on here before, but this is just a video

Hi Maxx1,

If you're talking about the instructable version of this video is mine, and it's there:
USB Cooling Fan from a broken drive

Yes, a search button works :) for you too :D
BTW, I agree with you (I don't like who rips off someone else)

Bye, and thank you for your feedback
So WHY did you repost it then?
BlindSight (author)  Maxx17 years ago
different form, for different people. Somebody can't playback videos or just prefers step by step instructables, somebody prefers a good video. I did it for that, have a good day Maxx1

You went to all that trouble, but didn't put a simple switch on it? I know it's easy enough to plug and unplug a USB cable, however I always prefer to wear out some cheap replaceable, than to wear out the usb ports/cards on my notebook. Have to think long term durability.

i like it very good use of what would otherwise be trash. although there is one thing i think you might want to fix. in the video you say "isolate all with tape", i think you meant "insulate all with tape"
sweet, i love mini usb fans. but the only thing is that your fan almost looks like its 'tripping out' (like not enouf torque?).
