Pictures of your mining rigs!

I made a bag thing out of a painters dropsheet to show how much air it moves.

That was TOTALLY entertaining! Looks/sounds to be on par with a leaf blower!

What's the purpose? I'm guessing you may be limited to DC power...or just had a lot of fans you wanted to put to use?

I always love this pics thread

That fan set up is impressive!  Never thought it would go so fast!

Your hands don't match with your face.

Video was really entertaining, though, congrats!

[crazyates]

Bwahaha! That vid was awesome. Nerds and their toys... 

However, I hate to burst your bubble, but it's already been done before.

Any thoughts?

crazy but nice

you could also try a bigger fan, like this:

230mm diameter, circular case, 264,0 m³/h airflow.

Can I play the big fan game too?

  It needs to run off a car battery jump-starter (600 A peak current) because none of my bench PSU could handle it. It needs about 200 watts or more. Even my small desktop PC ATX PSUs were no match.

Have you tried the same experiment with just one of the fans? AFAIK the fact that there are 12 shouldnt be that much of an improvement due to teh first fan being the only fan that intakes air - how about thrying it with them paralell instead of in series

I have 15 of these delta 120s - 252CFM - lovely for shifting air BUT too loud for continuos use (unless its in a server room) i have 12 pulling air in my server cab and 3 to 'play' with

I have a couple of those and they are just insanely powerful: http://www.youtube.com/watch?v=kDOSaPULFro

@Xian01 my guess is those powerbricks wont last 2 months like that...

 Why do you say that ? Decent air-flow and temperature in that room, and the bricks are not hot to the touch at all.

Ok, then it's fine... Just had a 60W running at 40W power brick fail on me after a year without being choked together like that... You're not even pulling 50% of max power on them then?

That's cool!!! But I've always thought that the fans would block each one's air... guess i was wrong, and that, gave me some cool ideas!!

thanks!

Those are actually not that good, 4 times a 120mm fan would get me like 400m³/h, with a cheap Arctic Cooling F12. The reason I used those fans were I got them off ebay pretty cheap (like 1-2€ each).
I plan on using nine of these:


Fan size: 92mm 55CFM, 32dBa, 3000rpm. Those should push some serious air I hope.

Anymore thoughts? Could anyone explain me why I need the exit (the left side) and not just leave it open after flowing throug hmy to be cooled units? http://img.gawkerassets.com/img/18adxj7fzzmaxjpg/k-bigpic.jpg

WOW!!! That's not noisy... that's not loud... that's a leaf blower!!!
Can you please detail the NE555?

Hi!!!

The exit has the same principle as the rear of a rocket engine - for a moment let's forget the fans and think only in passive air circulation. Since the hot air expands, it will hit the walls.
But those walls angle will make it go out, instead of returning.
Since the air exits, it will create a very low pressure in the middle, pushing the air from the back.

Oh, now I get it. I should do more testing . Btw, I ordered some temperature sensors (two), only need something to heat in the middle section. Should be fun
I'm thinking about using a big-ass-fan this http://www.amazon.com/Lasko-3733-20-Fan-Box/dp/B00002ND67/ref=sr_1_1?ie=UTF8&qid=1376038212&sr=8-1&keywords=boxed+fan
but I can't find the equivalent of a boxed fan here in germany, only round ones (I want a boxed one!)

What sensors have you ordered?
I had a lot of trouble that way. They were both expensive and hard to use.
I've been advised in MSP430 forum against the thermo-resistors type, and those such as DHT11 are too complex for my knowledge (and expensive for experiments).
As for heating, as I PM'd you, I'm thinking in heated water, for now.
But I've thought some months ago in this: http://www.iceinspace.com.au/63-292-0-0-1-0.html
BTW, I've found out yesterday's night that a 7ohm @ 10W resistor and a 12V@1A power source don't mate well, although they really produce heat. Too much of it!! 
Read somewere once, many years ago, that if we powered a couple of pins on an old pentium 100 processor, and shorted some other, it would heat up stable, but can't find that anymore.

Ill put up some pictures of my blade-farm as soon as I find my camera's charger, and the rest of my blades get here. I just wish this wasn't so dam addicting.
