Really, that much? I haven't been paying that close attention to Philip's post in speculation recently. But thought it was much less of a an increase. Ouch!

Ouch is right!

it is light weight easy to work with and is water proof

you could reverse the air flow on the fans blow air out those windows and you would basically have a hood from the material.

I would do
.........silver hood..........
miner >fan> fan> window

           silver hood
miner >fan>fan> window

use  two fans for the frame to place the silver material for  each window

get a roll of silver duct tape

              silver wraps the
               two fans
              wind tunnel
              _________
miner      Fan   Fan>>> window >>>> air out >>>>
             __________

Sounds great. That will be my next project very soon. I don't think I need a roll that large, so I will do up some measurements/guesstiments of the amount of insulation needed.
I'll have to figure out exactly what you are meaning with your diagrams / instructions. I'll get it visualized in my head soon. Not quiet awake/alert enough and the brain is running slooooowww.

Thanks so much for your assistance and helpful advice!!

Need a quick block or two before it jumps. That would be nice! Even one, please!

You are going to see a bunch of s7's & A6's dropping off due to price and difficulty. Unfortunately with bitmain releasing more s9's tomorrow that will rapidly pickup the slack.

They are really releasing new S9 ? Tomorrow?

I wish that coin price would see a little upward movement instead of the slow downward drip, drip, drip. That would make the large difficulty jump easier to swallow.
I haven't read anything about price speculation in the last week or so. Maybe I'll take a look now. Even though most, if not all, coin speculating is much less accurate than long term weather forecasts. Anyway,....

We Need Some BLOCKSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS!!!!! GREEN BLOCKSSSSS!

MAKE IS SO!

saw the drawings and cant help noticing a large square box called "BED"..... how are you going to sleep with a few of these Antminers screaming all day and night?

Ear plugs.

No, not really.
The current "coin room" was / is the spare bedroom. Now it is full of everything that won't fit anywhere else. It also has a queen bed that has stacked boxes, cables, cords, power supplies and silent S7's sitting on it. No room for sleeping even if it would be possible with the four S9's running 24/7.
With the door closed, it is still noticeable across the hall in my bedroom with both doors closed. But not too loud to sleep in my bedroom.

  slowly i began to understand all the problems.
i added some miners today. temperature increases enormous und fuses brake   
i think i need to do some adjustments......

Uh-huh...been there...done that...

Ya gotta pay attention to circuit capacities. My service here is 120v. I have only 30 amps of available service total. One S7 uses 14 amps. A typical household circuit (in 120v territory) is 20 amps. I currently run 6 S3s at home, but they only draw around 3.5 amps each, so I'm drawing around 19 amps for all of them; they're on two separate household circuits. I can't run the microwave without first shutting down two S3s. I ended up sending my 3 S7s to CryptoBoreas for hosting...that works for now.

I'm gonna take the time to photo my rack setup a bit later and post it. It appears to be a bit simpler...and cheaper. I've got (yet another) housing inspection tomorrow by a nonprofit co-op that the owners have retained to figure out how to finance upgrading the wiring in our complex so we can get 100 amp service in our units. Turns out that my blowing the main breaker for my unit several times around the first of the year got some positive attention. Additionally, another tenant bought a portable a/c unit, plugged it in, got it going, and then fired up their coffeemaker...and blew the 30-amp main breaker on their unit. I've been telling mgt for months that would happen.

Figure out which circuit breakers handle which plugs, and what your total draw is/should be for each circuit, when everything is turned on. Stay under 90% of that, and you should be OK for draw. If you run too close to the limit with only the miners running, then something like a frig compressor cutting in, or a microwave, or a vacuum, or even a hair dryer, could easily blow either a circuit breaker, or the main.

oh oh, very bad... a cable was melting and burning... tomorrow i have to set up better power connections.

replied and here is a photo, mock up for others to see

Yeah...you betchum bad...that's got to do with wire size, though most likely, not circuits. I only use server grade, 1KW rack-type power supplies, with gridseed adapters and 14ga pigtails. I've found computer psu's to generally not be as well built, and often use a lighter grade of wire in their PCI leads, unless you pay a bundle for a platinum 1200w unit. 12vdc can weld a wrench to a battery terminal if shorted. Don't make the mistake of using too light a gauge. Similarly, a household extension cord is almost never rated at more than 15A (at 120v); if you run a 1400w miner on it, you're loading that extension to at least 93% of capacity, and I guarantee it will get warm. As an example if you pull 18 or 19 amps (by having a miner and perhaps another appliance on that cord) you won't blow the circuit breaker, but you'll perhaps burn down your house because the cord could get hot, melt, and start a fire. Sermon over.

all miners together need 30,5 Amps now. so only the wires in the house are too smal. there is a 100 A main fuse so that should be enough for more miners. i will put a big cable direct to the main fuse.

Yep, if you MUST use an extension cord for your miners, for safety's sake, don't use anything smaller (larger number) than 14 AWG. The lower number the better in the case of wire gauges. Can be a little confusing when you have to think that the smaller the number, the larger the actual wire inside cable.

guys sorry to post this here... but maybe you can help me out

Ive using 2 s7-f1 on kano for 1 week, but today i dont know what happened and 1 of the s7-f1 stopped hashing, and it shows hardware version x.x.x.x i updated to the lastest firmware, switched to another psu, restarted the miner, restarted the router and still the problem persists, any suggestion?

I think anyone attempting to help will need more information. Are you getting lights on the boards, internet connectivity, can you log into the GUI, assuming you can; are all the boards showing up, are there X's or O's across the ASIC chain, is it connecting to the pool as in showing alive, etc.
All of the information you can think of. If you can get into the GUI, please post a screen shot of the status page.
Have you tried a hard reset with a paper clip?

More info, please.

Edit: This really belongs in the "Mining Support" or "Hardware" thread. Someone may move it.
