Turned a shipping container into a mining farm

[seanreit]

This has been discussed a couple of areas on the net, including this forum, but I could not find any example of anyone actually doing it.

I posted on Reddit, but for those that don't frequent reddit, thought this might be helpful.

From reddit:  Finally ready to share my mining rig shipping container. One thing I forgot to mention in the video is that some of the rigs are plugged into WIFI Connected 220V switches that also have Kw meters so if I had to do a hard reset over the net, I can. Shipping container was about $2,300 delivered. Temps on cards run around 60 to 70 C. I get around 4 air exchanges a minute.

I searched a lot and could not find any amateur shipping container mining farms. There are a couple of companies that showed animated ones as a product, but I couldn't find actual builds.

I would caution everyone that it's currently 50 F in Texas, and while I might look smarter than the average bear now, when it's 115 F this summer I might have a lot of egg on my face. I do have an extra 3000 CFM fan that can be installed, and we can put a car port over the container as well. I've tried to anticipate questions with the video and pics, but am happy to stay active on this thread if anyone has any specific questions. I built the container because my warehouse only has 120 Amps of 220 available and I outgrew it, plus it was just so hot in there I didn't enjoy hanging out in it anymore.

Container has a couple of security features, and is on a piece of land operated by a friend of mine, who happens to be a welder and runs a welding shop on the property. My agreement with him was to install everything and I supply all the material. Additionally, as many cards as he wants to supply, I will supply all the other materials and builds for rigs for him. He chose 2 rigs for now. Good deal both ways..

That's awesome! I am also in Texas and after trying with not much luck to find a suitable building to lease my friend and I are going to try a container. Although because of our brutal summers (as you well know) we plan to spray foam insulate it and then frame finish out the walls. That way there's good places to mount things and it will (hopefully) keep the outside skin from transferring too much heat inside. I am also planning to orient the intake and exhaust a bit different from you. I worry about drawing the air in on one end and exhausting it out on the other might cause uneven cooling of the equipment, especially in the back. Going to do it like the image below which should keep all equipment evenly cool.



Not trying to be negative, as you've done a lot of good work!! Keep us posted on how it does.

We are doing it right now..  We are about to move this mine https://youtu.be/l_ayQnZ-MDM along with two others to this https://youtu.be/WtnC2nT8B8o container!

How are you guys coming on your container mine? We did some work on ours today here is a link to the new video..

If you check out some of the people who have built shipping container homes, you'd probably be well-served in painting the top and sides of the container white.  That's probably the single cheapest thing you can do that will really help keep it cooler in the summer - there's been numerous people in the tiny home communities that have commented on what a difference that makes.

[Master One]

Congratulations, I'm envious.

May I ask what the costs for power are at your location?

Is the intention just to have a cheap housing for the mine or portability?

[crypto4pizza]

Wonder if my HOA would like this in my backyard 

[Michael20]

115F is very hot. Is it possible to cool without AC?
One idea could be, put long pipe's into the ground, this make some people with ventilation system for houses.
But humidity could be a theme?

[tg88]

I'm doing it too:

[manji]

when inside the Container, of course, sound of the RIGs are very noisy and how to the minimalize its sound?.

and when there is a storm, how to keep the container solid because if it rolled you know for yourself what will happen with the RIG installation.

[Dlikrot]

Lucky you Wish I had a big property, because this is actually a really good idea.

If you make an image search with "container bitcoin" you will find some results for amateur setups, like the above.
I think it's not an optimal setup, maybe in a cold environment...

[CryptoSouth]

For cooling we have constructed a false wall in the container, We are installing 7 whole house fans on the hot side of the wall. We will be able to pull like 35000 CFM of air through the container. No air will recirculate at all, If that is not enough cooling I will install a heat exchanger in the intake side of the container and use a ground water system to drop the intake air another few degrees but from my basic calculations the air flow alone should be enough to keep it cool..

We are going out to the site today to get some more stuff done so expect a new video tonight..

Just put up another video of our Container Mine.. https://youtu.be/GzROlhr4Fg0

I have a place to mine, just need to find CHEAP electricity...
Thinking of going solar this year..

[RYXES]

Get on the solar on top of the containers and this will be clean clean revenues.

[CryptoSouth]

Solar is not a option for us, Lets do some math to show why.

We currently have 100 miners that pull 110,000 watts. The average good solar panel puts out some where from 250 to 300 watts so lets use 275.

110,000 / 275 = 400

So we need 400 solar panels to power the mine..  Now I live in South Louisiana and we get a fair amount of sun. But the usable amount we get that we would be able to run the mine at 100% is only about 5 hours per day. The average good solar panel is about 200 each wholesale.

400 * 200 = 80,000

I would have to buy $80,000 in solar panels alone just to power the mine 5 hours per day. Then I would need a grid tie inverter and a 100kw GTI is about 30k. So all in all I am looking at $110,000 to run the mine 5 hours per day.. 

I currently use about 78,000kWh per 28 day month so

"78000 / 28" / 24 =  116 kWh per hour

I pay approx .075  per kWh after fuel adjustment so

".075 * 116" * 5 = 43.5

So I pay $43.5 to run the mine for 5 hours in a day that means the solar system would save me $43.5 each day therefore ROI on the solar system would be

"110,000 / 43.5" / 365 = 6.92

I would have to run the miners for 7 years to reach ROI on the solar panels..   


Conclusion $110,000 spent on miners would be money better spent as it would make about 1 BTC per month right now and the ROI would be less than 10 months..   



Just my .02

@cryptoSouth

Did you include the hours of usable daylight where panels may not provide 100% of energy but some % less that offsets the cost?

5 hours per day providing 100% plus 5-6 more hours of offset may change your calculation for payoff to much sooner.

7 years for payback on a 400 panel install isnt half bad if you knew you would mine the entire time.

[CryptoSouth]

I did not include partial as i did not feel like going that far into it..   Normally when I build a solar array we use 3x factor on a 5 hour day so we can insure we have enough to keep the batteries charged even when we have a few days of rain.. 

I build solar array's for the oil field to run PLC systems.  Even if you factor in 10 hours a day you cut the 7 years down to 3.5 the money would be better spent putting more hash power online as I don't know of any miner that is going to make a profit for 3.5 years..

Even if I were on a POCO like Entergy who is historically one of the most expensive I would not want to do solar, I would relocate the mine to a cheaper POCO..

@seanreit & @CryptoSouth -  Looking forward to updates on the builds.  You're "Gods among Men" thanks!
