Custom Built Mining Shed

So your power cost including delivery is around 10ct? is that correct?

also, cooling typically adds around 30% more power consumption when running at full load, so it isn´t that much more power cost.

It is a necessity in most parts of the US anyway.

From my experience, antminers aren´t that sensitive to a higher intake temperature of say 30°C.

guess that's what i meant to ask above.

OP: would you skip the AC unit in favor of simply using outside 30C air (at peak hours) in your shed, and if not (due to limits of the current ventilation CFM?) do you think a shed with larger vents and fans would be capable?

second part: is running an AC on a very small amount of intake air very effective if the air is being used and vented out hot within a minute or less? and does doing it that way mean it will add less than 30% (the general figure for closed-circuit cooling of heat) because the intake air (30C) is still significantly cooler than the exhaust (45C)?

lastly: whats the noise like? does it sound like a pool shed or does it sound like a vaccuum/box of fans when you stand outside or nearby?   (ie: would it annoy the neighbours or be obvious)

they can run fine in a room at 85f  which is  30 c


but he is in texas  which means 100 f or  38 c

so after sealing up the wall we're sitting at 86 degrees f on the cool side and 124 degrees f on the hot side. This is with the 32 miners running, and it isn't extremely hot outside yet. Shaxs and I are going to tinker with individual shields for each miner to try and contain the heat they put off so it's funneled directly to the hot side instead of outwards towards the other miners.


This is like the never-ending project...

sounds pretty fun and successful though! 32 miners is a lot of heat - are they overclocked or undervolted?

whats the outside temperature?  and as mentioned, what is the noise level like outside the shed - 32 S1 units make a LOT of noise when you dont have a wall between you and them

All over clocked. Outside temps were in the high 80s F.

Noise level is not bad unless standing next to it. No worse than the noise from an AC unit. I cannot hear them in the house.

Are you up to Fire Code on that building? Since it is connected to your home.

Code specifications would be great if given. And what code specs did you go by or did you overkill on the codes? Overkill on codes is a great thing.

Thats a good question.... probably not up to code exactly. The shed sits on an external slab backed up to the exterior of the house which is cement board (deem as a non-combustible material). We also have a nest protect in there for fire/smoke warnings. In fact it went off last night I think because there was a fire somewhere outside (you could smell it) and the fresh air intake brought some in.

Just a warning, google recalled a lot of nest. Becareful, man. Hope you live by yourself and not with children, wife & pets or putting someones life at risk including yours.

Only recalled because of the wave to dismiss option.

^ha, how did that feature slip into the final product?

*nest senses fire - send alert*
*humans rush into room on fire and flailing - wave to dismiss activated - returning to standby*

Awesome farm! I was thinking about setting one up for a couple of GPU rigs but nothing on the scale of what you're doing. I love the wifi controlled lightbulb, that's a really good idea.

Have you run into any issues with the miners since setting them up there?

[timk225]

Wow, you blew $4500 just setting up the room!  Kind of defeats the purpose of mining.  It's hard enough to make a profit without piling another $4500 on top of that!

Hosting would have been anywhere from $1,100-1,300 per month, per person when we only had 15-20 miners. With what we have now, we will hit full ROI in another 2 months or so, maybe less with the spike in price... Pretty easy decision in my mind, and I didn't have an issue putting my money to that.

Trust me, we weighed every option we could, and this was the best option, hands down!

The PSU's have been the biggest issue thus far. We're using the 835w IBM PSU's, one for every 2 miners. They have a nagging habit of shutting off and you have to fiddle with them to get them back up. Luckily we're getting them for between $10-$14 per, so I'm not too concerned with having to replace them. Other than that, there's not too many issues we're facing yet. Very curious to see what happens when the outside temperature starts climbing. We've had a very mild spring and haven't really climbed into the Summer temps yet (100+ f). I would imagine there will be some more tinkering in our future to combat that.

try the DPS800 with the gigampz board. You can have a 1000W supply at 208/240V for about $50-70 after the cost of breakout board, PCIe cables, and PSU

+1. shed is a smart move. Anywhere you locate them you are looking a $500-1000 rent or more, is a remote location, and likely would require some initial modification (electrical work to run 30A 208V wiring/panel/fuses will cost $1000-2000. That doesn't include AC installation if its needed or the shelving/power bars/networking/fans/lights/smoke detectors to run everything properly.

even for a full $4500, saving even $500 a month to host in a remote location will pay off in 9 months. Its a permanent installation and you keep the shed forever

Exactly! Plus it would be impossible to have 32 miners in our house.

Great job!
It sounds like you know what you are doing. I hope you do hit ROI as you have planned.

This gives me hope my little asics could be useful. I just need to find 20 more

HI

Nice mining room.... a few things.

I think changing from s1 to s2 miners would be a good option... what is it s1 mine at 180-200ghs and a s2 mines at 1th and use much less power and puts out much less heat... selling 5 s1 mining on ebay could net you $1k-1.5k depending on what you sell them for and how soon you sell them... so you would only need to invest another $500 to get 1 x s2 miner for every 5 x s1 miners you have right now..

or what about something like these miners.. http://www.cryptocoinsnews.com/news/spondoolies-tech-sp10-dawson-miner-masterpiece-bitcoin-miner/2014/05/28

and get a data cabinet like this..



you could find something second-hand for cheap on ebay I sure

last thing what are you doing about security for the shed and the miners... you don't want people walking off with them...

You cant buy the S2 anymore, just an over priced kit.

That's quite a project, and what a deal on those power supplies, $10-$14 per supply is an awesome deal!

How does this hold up in heavy rain? I see the insulation but between the dog door and vents I'm sure moisture gets in there. Do you run any dehumidifiers or anything like that?
