Medium Size Farm Buildout (Pics Added)

[NateDoggETH]

Pictures I know many have asked. I think this is awesome for the build-out, many of us would like to see how things are coming along with all of this. Where is your location? are you in the U.S.  north, south, east, or west?

pics will come at one time when I have time to sit and upload then from my phone to here. I am trying to make sure I get this up and running as fast as possible but at the same time not miss out on the important parts of living with the family. But like I said, I have photos throughout the process taken and will be taking a few more as I wrap things up.

I am located in southern part of USA and electric is super cheap for me. like China cheap at the moment haha.

Same here I too am living in the southeast of the United States currently. I have some photos of the setup that I built, I am currently running a 440 CFM fan in an 220 CuFt room in my house that houses all my mining equipment. That being said it is still not enough to completely keep the miners under 80 degrees. I hope that in the summer it will help more than in the previous summer running them with just a box fan blowing on them. That being said I am also running ASICs so that could be the main culprit of all my heat issues.

Is it cheaper than .05 kw/h? Thats what it is here in West Central IN.  

You should have a #6 solid copper running from your ground rod to your ground bus bar in your shed panel.  Your shed panel should NOT have the neutral and ground bus bar jumpered (IE: Not Bonded).  Your shed ground bus bar should have a #6 solid copper wire going all the way to the ground bus bar in your home (assuming your home panel is the first disconnect device after the Meter.  (Sometimes a meter base will have a disconnect and in that case the neutral and ground bus bars should be jumpered together there in the meter base panel and NOT anywhere else.

I might end up building or buying a shed myself just for mining rigs (easier to cool than a whole 3 car garage).  If I go big enough ill just have the power company run the shed its own 200a feed and install a meter there.  Just depends on what crypto does over the next 5 months or so.

I think you will find that the southern humidity and heat during the summer that you will NOT be able to keep your rigs cool enough.  Circulating 90 degree plus air does not cool much of anything. A fan does NOT make cool air.  It only circulates the air surrounding it and is slave to whatever its temp is.  You will probably need to install an a/c unit.  Either big window unit or a smaller system (Mini split will do well here).

[NateDoggETH]

I have #1 gauge wire (for voltage drop because of distance) from the main panel to my subpanel in the shed. I do have it set up to where I can have a dedicated 200amp service if I should choose in the future but I would probably just get a ware house at that point (dreams).


I will be having a portable AC unit in the shed possibly during the summer months but I am honestly not to worried about it as of right now.

I know that exhausting more hot air than circulating it will help 90% of all heat issues. the 10% will be the AC and other circulation of fresh air from outside (away from the exhausted air).

I will continually be adding more and more exhaust fans or just upgrade to a higher CFM fan if needed to upgrade to handle ventilation needs as things get bigger and hotter inside and outside.

and to answer someone's question if its under .05 per Kw... yes. I have flat cost regardless of usage (so that means unlimited). I live in a semi wealthy neighborhood (trust me I'm not rich by any means) so I turned off the pool heater and everything I could to just switch where my electricity would be used by the miners instead.

Your feeder #1 AWG wires are not the same as your #6 Ground wire.  There should never be any voltage on your ground wire and never any current flow on it either UNLESS there is an electrical fault in the shed thin there will be current flow until the breaker that feeds the fault trips which is almost instantaneous.

Yes that is true.

I do have the ground rod in place with the right gauge wire going from rod to grounding bar in subpanel. All work was done by a master electrician. I just asked a million questions and read up on what he would be doing to learn also. But that's how I am, if I want something done that I cannot do, I wanna learn while it's getting done.

As tax return season is coming quickly (for most people with typical jobs) my wife and I have decide to pull the trigger and run electricity to the shed in the backyard and start scaling our mining operation up.

We currently have a free 50amp breaker from a hot tub that was removed before purchasing the home. The house is set up for 200amps total base on the main switch I see on the Electrical Panel in the garage.

We are in the process of getting bids to run a sub panel to the shed for the electric. But before we have electricians come out and ask us questions that may be over our heads (like how many 220v and 110v would we need etc.) I figured I would ask for a rough idea on here. You advise will be just that.... advise for me to continue to brain storm on and have the final plan up hopefully by Feb. 1.

I would like to have 3 220v outlets that I would have 3 PDU plugged into for the miners so that if a given.

How many 110v outlets would be needed for fan (3-4 box fans for movement and 3 450 cfm vortex fans for heat exhaust--cool air will be from passive cooling because of the negative pressure.


Questions I wanna know before I ask someone in person:
1. If my panel is only 200amp, can we reduce any amps for the bedrooms to give more Amps for the shed?
2. Can we add a brand new 200amp box just dedicated for the shed but would be billed on the same electric bill monthly? (might be a eclectic company question)
3. Can I put the electrical wiring and the Ethernet wiring in the same trench or run them on the fence line to the shed to save from not digging? (Shed is approx. 170ft away from panel)

any possible ideas, or other things to think about please let me know. I don't want to spend $1000-$2000 just installing electric when there might be better ways

#1) It's 240V service, not 220V service. (That 20V difference is 600W on a 30A circuit).
#2) You need a 10/3 (10 awg 3 conductor) wire for each 30A circuit. This will cost you like $1/foot
#3) You'll need a conduit large enough to house 3 conductors. Another $1/foot.
#4) You'll need 3x 2 pole 30A breakers ($20ea)
#5) You'll need 3x L6-30R at the end of your conduit, each connected to a single conductor set. ($20ea for the housing and the outlet)
#6) From there you'll just need to find a PDU with a L6-30P that's capable of connecting to the L6-30R. There are a lot of these around with a variety of features from monitoring to switching. (Being able to remotely reboot your miners is a nice thing, but it'll cost you)

I would estimate materials cost for your build at: $800... From there it just depends on what you can get an electrician to do it for. Maybe you can run / bury the conduit with the cables in it (that'd be the costliest part of this, the rest of it could be done in an hour or 2). With these parts you'll end up with 90A of service with 72A usable (17.2kW) over 3x 30A (24A usable) lines.

From an installation perspective... You'll need to install the 2 pole breaker, insert 1 red conductor to one pole, insert 1 black conductor to the second pole, and green or uninsulated conductor to the grounding bar (WHICH IS NOT THE SAME AS A NEUTRAL -- DON'T KILL YOURSELF THINKING THE GROUND AND NEUTRAL ARE THE SAME). Run the conductor through the buried conduit to your shed. connect the conduit to 3 junction boxes each housing it's own L6-30R. Connect black and red to their respective hots, and green or uninsulated conductor to the ground on the receptacle. Install your PDUs. Start mining, then switch your concern over to cooling with summer approaching

Here's my PDU: https://www.amazon.com/gp/product/B0013HY9E2/ref=ox_sc_act_title_5?smid=ASF0S1GFIHF5V&psc=1 -- But it does only have 2x 15A breakers which means you can only use only 12A on each breaker bank. There is a monitored version (cheaper) which has 2x 20A breakers, but doesn't give you remote reboot functionality.

If your house is anything like mine, you won't have to worry about voltage drop. I'm running 245V at my outlets. Down at my barn (maybe 150ft) there is zero voltage drop.

Thank you for your post.

My shed has been wired (yes 10/3 with 2x30amp L6-30P outlets for the Tripplite PDUs that are in there right now. I will add 1 more outlet when I need it. The PDUs are not switched but just a basic version to get me up and running on my rigs down there.

I currently have 3 rigs running right now and the shed is staying around 65degree (F). Cards are running between 46C-65C depending on which card and where it is in the shed.

I have order 1 more exhaust fan rated for Approx. 500cfm.

I messed up and said I had 2 400+CFM and I really have 1x190cfm and 1x450cfm vortex fans. So 1 more additional exhaust fan will be good for the shed. I plan on cutting a smaller intake hole for the 190CFM vortex and having that on a fan controller to control how much fresh airs gets in. (my idea is to help maintain humidity this way also. not an issue not but thinking for the future) I been and seen other peoples ventures (grow rooms) that needed lots of exhaust and this is what they recommended I do. 

Finally, I am order the last 2 mother boards today (hopefully) and will put those rigs together this week and throw them in there.

Once I get all rigs and the new vortex fan hung up, a final video will be made. I will include some parts of the other videos such as the running of the electric and Ethernet cords to the shed from previous photos/videos I have taken.

I am approx. 85% completed with the shed in my opinion though. Thank you to everyone who has commented and been patient as I get the video ready. Once you see the completed video, you will be happy.

My house is super quiet now that I moved those rigs to the shed to test the temps and stuff haha.

Your master electrician should know that the NEC states the the ground rod connects to the ground bar in THE FIRST DISCONNECT DEVICE which is typically your main panel in your house.  If your main panel is the first disconnect device then it should have the gorund and neutral jumpered together.  Your shed should have a #6 wire running to the ground bus bar in your main panel (house) and there shouldnt be any ground rod at the shed let alone connected to the directly to the shed main panel. Shed should also NOT have ground and neutral bus bar jumpered.

So...I gotta ask.  Did you let the wife know what the 'new' ROI is going to be with the price and difficulty changes?  Things have looked alot different now compared to when this thread was started.

Either way, more power to the adventurous.  Good luck!

When we looked at the projected outcome, the difficulty and ROI was definitely lower on both fronts.

However, we were not going to cash out any coins for 1+ year anyways. We actually received the ROI back from a surprise bonus at work just last week. We applied that straight to the mining costs and are about $2000 under still right now. I currently have 12000 USD for 5 rigs (6 GPUs each) and about 1500 of that is for maintenance  hardware such as exhaust fans, security system, wiring the inside of the shed such as outlets, etc... So I should be out of the red very soon. Hoping for 30+ ETH by end of 2018 and if ETH goes to $2,000+ I’ll be set. We still are keeping out day jobs which pays more than enough.

I just got the 5th rig build over the weekend and waiting on a new server PSU so I have enough juice to run all the GPUs on that rig.

So far without tweaking I have the following hash rate:

rig1: 174mh/s (3 sapphire Nitro 570 8 GB Samsung memory & 3 ASUS strix 570 4 GB Elp. memory)
rig2: 165mh/s (6 XFX 570 4 GB Hynix memory)
rig3:158.8mh/s (6 XFX 570 4 GB Hynix memory)
rig4:170.2mh/s (6 Gigabyte gaming 570 4gb Samsung memory)
rig5:117.4mh/s (4 Gigabyte Aorus 570 4gb 2 Samsung memory & 2 Hynix memory), will add more GPUs when the 1200 watt server PSU comes in)

I will be doing heavy tweaking throughout the week but most likely it will be on the weekend when I shoot my video for everyone.

Thanks for the patience on the final setup. It still won’t look at pretty as BeerMans shed or others on here, but is a work in progress. I will continue to add more Rigs as I can of course

I will have a 6th rig built but it will be to tweak all new cards and for troubleshooting. I have 2x1070s from a friend (lucky me right?) I will put those cards on the test rigs until he gets more for his own.

[CointoHash411]

Nice,

Hope the ROI does pay off, I have already met my ROI for this past year. I am hoping that my other hodl's come out of this slump, like MUSIC Coin and others. If Music would reach 1.50 to 2.50 it would set me right to open my own mining datacenter. I guess dreams are free for now. I am still holding out on those pictures of your build out.

[NateDoggETH]

I am hoping for a video this weekend of everything (depends on if I can get my other rigs in the shed). I have been dealing with massive amount of rain in my area so I have not done the organization of the shed yet and I still have 2 rigs in my house that I need to put in the shed and im not doing that until the rain stops obviously. 

As far as ROI is concerned, since we (wife and I) received bonuses totaling $6500, we applied that to the cost of the rigs and we do have enough coins now that if we cashed out, we would be 100% ROI and more. However, we aren't cashing out until end of the year hoping for an increase in price per coin.

Temps in the shed for 3 rigs is about 75f when it is about 65F outside. I have both 450CFM fans exhausting now out the roof of the shed and have a small 190CFM for an intake. Humidity has been around 10%-30% depending on the time of day and outside weather.

[NateDoggETH]

update on the shed. (*2nd attic fan was added to shed today as well so testing for lower temps now*)

I have added 2 attic exhaust fans (the 1650CFM fan is right behind the GPUs to exhaust heat and the other is 1300CFM on the side window for more exhaust) on each window and I have the other 2x450 cfm fans exhausting out the ceiling through ducting. All the miners are staying at 45C-60C depending on card location. Only 3-4 cards are hitting the 60C temps though so not to worried.

For intake, I simply cut 2 rectangle holes in the floor and have a 190 cfm fan sucking in on 1 of them and the other is a passive intake. Holes are located at the front of the shed as well for a wind tunnel effect. I can physically feel the air movement when the door is shut.

Temps outside the shed have been hitting Mid 80s-90s in Texas these past few days.Temps inside the shed are around 85F-90F at the peak heat of the day. I have not had any issues with temps so far as I'm simply exhausting heated air faster and bringing in the cooler air for a natural window tunnel.

I have a lot more room to add more Rigs in the future if I need or want too. I have seen a ton of GPUs for sell in the area and I know more will continue to flood the craigslist market. Waiting for the right time to continue to grow. Until then, I am dual mining ETH and DCR. I have about 965 MH/s ETH and 18500 MH/S DCR.  I have unlimited electricity for $230/month +tax. That includes distribution/transporting fees from electrical company.

Finally I have taken some pics for everyone to see. I still have some major organizing to do but here are the 5 x 6 GPU rigs I have in it so far. I have a 3 GPU rig in the house I'm still tinkering with but it will be moved down here soon.

Here are a few pics that I took today.

Okay, I'm in TX too (DFW), and do you mind letting me know what's the secret with the unlimited electricity? Wind power, solar power setup?

BTW fantastic shed! I have my 5 mining rigs in my empty garage now, it gets rather hot , need to crack the door open a bit to cool it down.

This is pretty cool. I'm running just one rig right now but really wanting to try and make a move like this soon.

Are you worried at all about rain with the holes in the floor?

[NateDoggETH]

No I am not as of now.

I have 4 layers of mirco screen covering the holes (stapled to the floor) and the holes are also about 1 foot off the ground. as far as the windows are concerned, I am going to plan outside covers on them to help with rain blow back during our storm season. The air force from each fan will also help prevent any rain from getting in until the fan covers are in place.

[CryptoPlay]

Really nice project. Thanks for sharing this!

[NateDoggETH]

Really nice project. Thanks for sharing this!

Thanks. So far the majority of the cost for all the equipment is paid off. We r just going to sit back and collect coins hoping for a high payday in the future now. Generating about 2.2 ETH a month right now

[BeerMan81]

I saw the pics! Finally!!! I would love some more, perhaps one from the outside?
