Do you have any stats on the full setup?  Things like total container hashrate, internal/exhaust temps, decibel levels, miner stability when fully loaded container is sealed etc...

That would be most interesting.





Intake left, "cool" aisle atm: 13.81 degree centigrade
Intake right, "hot" aisle atm: 14.12 degree centigrade
exhaust left, "cool" aisle atm: 17.85 degree centigrade
exhaust right, "hot" aisle atm: 24.2 degree centigrade

Both of the fans are running in delta now - we want to try soon to let the left one spin in star mode, so there is some underpressure in the hot aisle which should prevent the miners blowing hot air over to the cold side.
Regarding decibel levels: I have measurement equipment, but the place is noisy anyways - so it's hard to tell what's causing the levels. It's granted that the miners are louder than the big fans.

Awesome, thanks for the data.  Is there a rough estimate on your hashrate for that 120kW?  Just curious.

Keep up the great work.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

Sorry, I honestly don't know - you would have to ask my clients for that...

I'd definitely question the strength of the leg supports. What's the empty (no miners) weight of the fully-outfitted container? Adding 114x S5 to the mix will increase the weight by a good 900lb. Have you the engineering figures on the strength of the attachments, shear strength of the bolts and drilled-out tube?

Also, is there an option to run C20 cables instead of C14? If we're looking for space density, 2KW and 2.8KW PSUs (as well as SP30 and up) require C20 cables.

You forgot to add the weight of the operator inside. Somebody has to come in for maintenance once in a while and move around, which can change a lot in the distribution.
Also, with all the wires inside there's not much room left for a person.

http://en.wikipedia.org/wiki/Swap_body You are allowed to put 16to inside that Smiley

Also the aisles are 90cm in width, which is sufficiently spacy even for bigger persons.

Serious mining anyone?



We have a new, improved air intake layout, also we will be able to spin the fans at different speed so to create a lower pressure in the hot aisle.



As for the stilts: We had a licensed structural engineer engineer calculate the whole thing, nothing in the dimensions changed, we can put in up to 2 metric tons of payload at normal European wind speeds.
Customers can have a CE sign for that.

Thanks for your attention!

Some pictures:

"Old" stilts design vs. new one (on the right):

Air outlet, with side walls to prevent the hot air from getting sucked to the air intake again:

Inside:

Hot aisle, faster running fan:

Cold aisle, slower running fan:


Letting the fans run at different speed functions really nice, you can feel a definite airflow from the cold aisle to the hot aisle over the whole shelf.

You made quite a nice piece of gear. Too bad btc is down so much.

 This would be a perfect piece of gear for someone in Washington state USA power is under 5 cents. I would think the shipping to USA would be far too high.  I do wish good luck for your gear as It is well thought out.

If somebody wants to set up a (near) Washington State company producing this things with me - I'm all open for it. This is really by far the cheapest way to set up capacity and it works just perfect.

Now that would be a good idea.  That State is far and away the best state in the USA for power cost. Making those containers in the state  would be  really practical.

If they could manage to do a low priced version of one if these that would be interesting.  I could see people going in together to buy and splitting cost.  But it has to be a practical cost.  If it cost's to much it would lose all the benefit of cheap electricity.

The main cost is the container. If I'm not mistaken a used 20ft-er can be had from about 6k USD. The rest depends on how much time you can invest in doing it yourself and your skillset.


I'm glad to see that this project seems to move forward!

$6000 Huh  You must be buying new......  Roll Eyes

Most ports have PLENTY of used containers,in really good shape  Cool

Then get a flatbed to haul it for about $100-500 depending on how far you go with it.

I thought it sounded a little high aswell.  I know I have seen used ones sold for storage for much less.

On new i have no idea how much it cost's it could be the 6k.   If you look at the one they showcase in front page they are wanting 18k for it.  I think it is very nice, but that is a lot of cash.   That is what I was referring to when I said I thought you could do a lower priced version.

The second hand containers you get to buy are usually the ones which the transport companies don't want anymore. Guess what - they really know about containers....
We used "new" ones for this - new meaning produced in far east, one time loaded and shipped to Europe.

I don't know if I would agree about this completely.  I worked for a big company that I did international transportation for the company. They made items that go world wide (i won't name company).  But they shipped on boats, trains, and semi's.   The biggest thing they cared about was size of container.  I help write some of the code we did not track containers uses.  And one use might take a big tole if treated wrong, and one use might not hurt it much at all.  So number of uses was not really important.

I would agree the ones sold are not brand new and near as clean/nice as what you are using.  But you could get a decent one not torn to heck.  I don't know prices as I never really cared to buy one.

Don't forget,in the US we don't ship out much but we import alot!!! So there's an ample supply of decent used containers in most any port  Wink

Go shopping guys!!!  Grin

I plan on building my house with USED containers BTW  Cool

We did a tiny tiny bit of export of us.  Most was import as you said. And a surprising amount of US to US.  And we imported to a lot of other countries aswell.  But on containers our product was loaded and they sent it on a boat for a decent voyage.   These products were not time sensitive, so you just shipped them far enough in advance to cover demand.  But travel time was quite a bit on the boats. 

I can say I have worked with most of the big companies on shipping with containers, and if something is imputed wrong it is a huge pain.  Not all the companies use nice new software, so you are getting tons of legacy software tied into new software.

But yea container prices can be a lot less used.  With the big companies they have HUGE volume so they their price on containers is less then what a individual would get going to a company pumping out new ones.
