Do YOU know the muffin fan?

DuplexEmotions · 06-March-04, 08:49 PM

bought 8 of these today at a stately $3 each.... I'm not sure why, but I'm sure I can put them to good use. They measure approx. 1"x1", 5v.

Why did you buy 8? How much air can that little thing push?

1. I have no sense of value.
2. haven't hooked them up to anything yet. need to drag out my old secondary PSU for that. I'm looking up the model numbers now.

EDIT1: A friend of mine is doing a fan-in-mouse mod and a fan-in-keyboard mod for physics, so I can probably help him with these.

EDIT2: 0.985 sq in, .4 in thick, 1.85 CFM @ 10,000 RPM.

looks like something used you hdd cooloing.

AltoNova1 · 06-March-04, 09:15 PM

where did you score those? did you get them online or from a local shop?

DuplexEmotions · 06-March-04, 09:18 PM

I got them from American Science and Surplus, a place kinda near my house. They have an awesome selection of fans (275 CFM, anyone?) and you can order them online at www.sciplus.com . Some of the stuff you can only get at the store, though.

10k RPM damn, that will get annoying fast. 1" hmmm. thats 25mm that is proly the smallest fan ive ever seen. Hook it up see how loud it is, i might need one or 2. (depends on noise)

I hooked one up to a spare PSU, ran it at 5v, blew a good amount of air for the size and not too loud. John likes.

i was wondering something. There is a key ignition that says it is a "momentary" switch. The momentary part is as long as you have the key turned. I was wondering if this would work as an on switch for a computer? looking to do something different with this case i am working on for my wife. It is the 6th item down.

"Insert the key and turn against the spring to close contacts for as long as you physically hold the key."

Looks like if you wanted to use it for an on/off switch you would always have to hold it to the on postion sense its spring loaded.

DuplexEmotions · 06-March-04, 10:23 PM

the way it would work is simple. It's like starting a car. if you turn the key, the computer will start. if you hold the key turned, it'll read as holding the button and after a couple seconds it will shut back off. when you let go of the key it will bounce back so you can remove it. I was acutally going to pick one of those up, but i didn't see one sitting around. it'd work well for a computer lock.

Reverend KWR · 06-March-04, 10:25 PM

Yeah.. ok, i thought hte on off switch was a momentary switch. So, i guess i will order one... oh wait, gota see what it is rated to make sure everything gonna work.... after that i guss i will order one and try it out.

Not so. PC power switches are meant to be momentary switches. Providing the voltage and amperage rating are ok (and I am sure they are) it should work fine.
