This makes me want to gut the building we have in my back yard we just put a new roof on and do this with less Miners because it's not as big an i may, i live in Maryland so the weather won't be like Texas in the summer, i lived  in Texas  for 2 years once, i have family near fort worth Texas, i could run it all 24/7 an not worry about noise any more in the house an one of my Neighbors told me he would help me remodel, if i do it .

What is stopping you? Come up with a cooling plan, make a sketch. Plan your power, then go! Show some pics.

Good work sir, very impressive indeed, but yun is still my fav

Yun is my hero lol.

Both of you are my hero! I've been followed your and Yun's threads for a while.
I just started small with few rigs and I'm going to setup more soon. The 2 biggest problems I faced are noise and ventilation, then reading you guys'sharing, now I get the balance between them.

So thank you and Yun very much!

Glad I could help with your plans!

Busy day! My Dad was in the shed doing some stuff (what did he do all day...?) I came back from school and helped finish mounting some studs (At least he had the marks made) We also realized that the 120V circuits need to be relocated   The electrician wont be happy, that we had to temporarily tie wrap them to the 240V circuits 

[BeerMan81]

Re-installed the insulation after the new studs were installed. All the baffles are mounted to the new studs equidistant to each other so the airflow is not constricted. They should be around 12 inches apart (after installing the foam padding). The order of installation of the plywood pieces seems pretty chaotic, but there is not much room to move around, we have to do things in a certain order.

When it is all done, you will not see any insulation, plywood, or studs as the whole area will have sound insulating foam to dampen the sound of 15 Antminers and 2 exhaust fans. Much more left to do, and S9 #2 is coming next week!

as a fellow houstonian, i've been following yours and yun's threads for a while. so during the summer, you guys just run it using fans, no a/c nothing? no issues with heat? all my miners all scattered all over my house right now and i'm a bit curious about the summer configuration. was thinking about setting up a small shed and put some fans in there.

i was a bit worried about houston summer heat being too much.

Heat is not an issue. At one point, we had rigs all around the house (to spread the load), and obviously the AC could not hold up (but we had to keep mining). It occurred to me to try to put a couple rigs in the garage (so the AC did not have to work too hard), and you know how hot that gets! I seem to remember the temp was like 110F (43C) or so when fully closed. We cracked the garage door, about 4 inches and put a couple box fans and a few cardboard boxes to funnel the air outside. Never had any issues at all.

Consider that a GPU will happily run around 70C (158F) without any issues. Cooling them is not an issue as long as you exhaust the heat.

Nice one DUUDE!
What about the temperatures? You are getting lucky that the winter is comming
Are you planning to put all your hashing power on one coin?

During the summer, one rig was around 75C MAX, but the rest are pretty good. I think i know how to resolve it before next summer. All Ethereum rigs. Antiminers, still looking at the profitability, but will likely just have 9 S9s on Bitcoin (maybe some BCH too) and 6 L3+s on Litecoin.

Nicely done! Maybe i will try and build that kind of a "house" too. For now i have "special" mining room. The temperature is arround 16°C with 26 GPUs mining inside I know this is not 100+ GPUs, but for a start is ok :p

How much money to spent? I think $1M for your "ETH ASIC" 
Good luck for investment, hope long ride for cryptocurrency and i hate ASIC

i think if all goes well with my small mining setup, i'll expand to a shed on my upstairs deck (land is costly). I'll probably kick it off March. Builds like these are packed with good information

[BeerMan81]

Working with a weld shop to build us out an exhaust piece for the AntMuffler. Made some sketches using the laptop touchscreen.

[BeerMan81]

Worked on the network today. I have two new used switches, a Cisco SG200-48 and SF200-08, the first being deployed to the shed and the latter inside the house. When we buried the network cable, I installed 2 ethernet runs (just in case), but later it occurred to me I could have them both running simultaneously in a fail-over state. I tested the Link Aggregation (LAG) before deploying the 50-Port switch to the shed. Would you believe it was only $18 shipped?   The fail-over seems to work great! only a few ms before the other link picks up.

The great thing about the new switch it that it has 2 GE ports, whereas the old one had none. Do you like my custom rack mount?



As you can see below, the old switch is quite full. All 24 ports are being used for 16 rigs, 1 uplink, 2 S9s, 2 L3+s, 2 SRRs, and 1 Desktop PC (Proxy Server). So, no room for the other 8 Antminers that are expected tomorrow!

I will have to relocate all the cables from the old switch to the new switch one at a time. After all that is done, the LAG will be live. and the old switch can be removed.

Also finished installing the fans for the Ant-Muffler today! You can see the custom "bookshelf" is in front of the fans as well. It just needs shelves and Antminers.

You're so fast with that impressive progress. Way to go BeerMan81! By the way, have you tested the noise level of this fan?
I'm consider to setup more 2 fans for my minin farm and I expect that fan's noise level should be less than 65dBA, but I checked around not much high speed fan could meet that low noise level.

[slanislaw]

Impressive! How does your neighbor like living next to a fan factory?

So far so good. Those fans point at my house, so i don't think they can hear them. The antminers on the other hand, loud.

Ya, well when you have 8 more antminers coming in, and nowhere to put them, a sense of urgency sets in...

speaking of which...Christmas came early!

You wrote: "We went back and forth with Centerpoint Energy and the only thing we could get was as follows: New underground 400A service from the Transformer to the house, terminated to a new 320A meter can (80% load). From there the load is split between the home (still 100A) and shed (225A). The cable that feeds the shed is the same size as the one feeding the house (capable of 400A) but the panel they installed is only rated for a certain size. I may have him come back out once I have some ASICs pulling more juice to see what other options we have."

I am in Houston too and wanted to go from 200amp service to 400amps.  Centerpoint said I would have to pay for a new transformer (the current one serving 6 houses is 50 kVA), pay for the concrete pad that goes under it, pay them dig up a bunch of my neighbor driveways, their landscaping, repairs to same afterwards, etc.  The total cost was nearly $30k!!  did they charge you too?  how much?

That is awesome! What model of power outlet strips are you using (look a bit like pack poles). Looks like the name could be TrippLite but I can't see any model info.

Thanks!
