Hi,
has anyone mande some experiments how to attach more than two hashboards to a S3 controller board.
Or - alternatively - use the available free ports in a S5 miner to attach S3 hashboards perhaps?
Any Frankenstein-Antminer experience welcome. ;-) I have several partially working devices here and would like to make use of the parts as good as possible.

Please move -> Mining / Hardware
I don't think either of these is possible. If you had two extra S5 boards depening on which firmware you can have 4 S5 boards. But have never seen a successful mixing as you were wanting to do. Also on a lot of the firmware's only 2 ports work. So you have to use certain ones like I said to even to the 4 of just S5 boards. |

Selling items really has been a good bump. All mining related items, as that's what I had and needed to get rid of some.
Also signature campaign. If you are a full member or higher I highly suggest you looking into it if you have good post quality.

The people who own these faucets are doing us a favor they should profit a little because they are helping people like myself get into bitcoin be a bit more grateful
It's not really doing you a favor when your doing things to make them money. Were talking about very very small micro payments. There are entire threads on better ways then faucets. Yes some do faucets but you will make cents for hours of work. That does not work for most people. Just to little pay for the amount of time and effort. |

Im doing captcha solving i earn bitcoin every week and join signiture campaigne the more hinger rank the more you earn.....
do you use bots to help you out? or are you doing all these manually, it must be super tiring to do only for so little btc though.. The ones he would be solving are one bots cannot do. They do not pay people to do capatcha on ones that OCR can solve. It's the ones that cannot be done automatically they pay people. So he would be doing manually as all others on service. Its normally a horrible way to spend time as pay per one just is very low. I don't suggest this way to get coin. Do you have any way to earn much bitcoin sir than solving captchas? by doing captchas i can earn 4-8 dollars a day... if theres any way to earn much bitcoin please inform me and i will change my work I personally do mining as my main "crypto" but it's not something everyone can do. Also I do signature campaign. And sell stuff from time to time. If you have services you can offer you can make a decent amount depends on services. But capatchas are not a good way. 1 day of working a job for most earns way more then a tons of hours typing capatchas. |

Bank on $500,000 - 700,000 per Petahash and you won't be too far out.
That assumes you can find a company willing to sell you the mining equipment at a reasonable cost and don't forget about physical and internet security systems.
Physical security and full time staff. You will need 24x7 staff. So very location based on this. And electricity cost is very location based. The honest anwser is it is something you won't do unless you have a lot to invest. A lot come here and ask about it but very very few build a farm like they ask about. |

It should not be heat with the ac. But you mention pretty darn hot outside. If you try to put a fan so it gets some air going through miners does it help?
Right now with it pulling air from corner just seems not much air flow. Might or might not help worth a try though.

Currently there is only BitMain left in the personal home mining industry, the other companies like KNCminer and BitFury have already chosen to fully enter into industrial large mining farm business with VC investment long time ago. And the rest is Spondoolies-Tech, since they've chosen to cooperate with Genesis Mining for cloud mining, there is no strong evidence that they will release any next generation home miner soon.
There is some old gear though on the market that could fit the 2T or add up to the 2T mark. It just depends on his electricity price. If it's cheap he does not need the latest and greatest miner. An older one might even be better ROI for him. Just a lot of factors. I do think we can call this thread dead though. I don't think OP is coming back. |

mybad the dns IP should be 192.168.1.1 unless you use a custom DNS .
On DNS server I really like 8.8.8.8 that is Google's DNS server. Very easy to remember and I have used it in many different miners. Never had a problem with it you might give it a try. |

Selling older equipment to new homes. I recently went through my equipment and sold a decent amount. I went by efficiency and the ones that did not meet what I wanted sold on here and ebay.
Old gear still brings a decent amount depending on what it is. There are many places with lower electricity prices and people in these often buy used gear. It works really nice a modern miner has a few owners in most cases before it's finally unplugged.

It is not going to be a legal way "Replacement/warranty for egifts within 3 day of purchase date if the card INVALID" Anytime they warn to use in a certain amount of days in that link it's 3 something is up. Most likely they are from stolen credit cards. They want people to place order quick to try to get items before company makes gift card invalid. It is sad but most likely what is being done. |

same happened to most cloud mining (like cloudminr.io) at first they are paying but after sometime they will vanish  With a ponzi first people often do get ROI. They run it until it is best for them to shutdown. This is why it is so hard with cloud mining to pick ponzi's. Yes some pay today.... but does not guarantee tomorrow. Use your own metric to gauge ponzi. But mine is do they have mining equipment, look into brand see if true. If a site is not able to say what they are mining with, I would avoid like the plague. With Cloud mining.website nobody get ROI. Im from the first days and i have maybe around 65%. No comment. They pay dust from 130 ghs i have 2-5k sat per day (0.00005000satoshi max) to get ROI i need around 3 years more.. u know what that mean..  I think reasons like this could be why in a few posts up I was ridiculed for my posts in here. I don't think some sites want you to look into history and ask questions. I am telling everyone when doing cloud mining ask questions. A big one is what equipment are they using, as most cloud mining sites sadly do not really have equipment. Look into history if ROI. Don't be fooled by fancy charts and promises. |

LMAO, look at one of my older posts, I knew for a fact this facility would overheat based on what I saw... Little do these guys realize, you need about 150cfm per KW of airflow... That facility @ 1.2mw does not have a 275,000+ cfm worth of airflow through 36'' ducts...
What a joke, the concrete structure makes it a heat trap / chimney. The white smoke test they did took several minutes to clear out... We fully cycle our air from intake to exhaust every 6 seconds... Yeah, so a white smoke test in a properly designed facility @ 100cfm per square foot vacating air allows you to keep your units cool. And the smoke test, would simply flow from intake, through exhaust, and be 100% clear in less than 10 seconds..
These guys are attempting to condition air, and not move enough of it, leaving them with massive hotspots, and expensive PUE, and a horribly inefficient system.. The only thing you have is .03c per KW/h compared to china's .04 / .05 cents per KW/h
Can't wait until we go public in some of our assets so everyone understands why they can't compete... I mean, look at Bitfury, they have a facility in Georgia (the country Georgia) directly under a hydro powerplant, paying less than .03c per kw/h, evaporate only, don't have to worry about compressors, and have about 20mw+ of capacity and expanding...
With the changes in heat sink design and methodology as well, you don't even need to treat the air.. You just have to move a lot of air, even if its 90 degrees across the chips rapidly and your fine... At least the direction bitmani is going with there small chip set.
Good luck if you go in this facility.. Why do you think Spoondoolies took one look at the facility and said no way... They decided to go to a different datacenter in Washington and a footprint @ vern global Iceland instead? Bitcoin miners consist of two groups now, large industrial players, and hobbyist, don't expect to make a dime... Its a hobby YOU pay for, not get rich on... You can't compete with my sub 40-50 dollar per KW cost including overhead staffing and cooling... And the fact that in massive orders, we pay about 50% of what normal people pay for equipment from the manufacturers due to large scale contracts.
If you have free power, and live in a cold place, YES! you can make money, these guys can't even make money if they are by themselves building this facility with compressors and attempting to treat air. I'm sure the capital for the contractors they used too was excessive as well, that looks like a very expensive facility that can't even run at 60% of its promised capacity during the hot months... You guys are lucky its cooling down, you'll have 6 months to get your shit together.
I think the problem is some people try to be cheap. They expect a asic data center to be like a server data center. They are nothing alike on cooling. Were talking about a lot more money into cooling. Depending on climate evaporation, just massive CFM, etc. Depending on climate is best cooling method. But regular AC is never going to be good for asic data centers. What happened to this place? |

Bitwisdom is going lower then I thought we would have:
Bitcoin Difficulty: 56,957,648,455
Estimated Next Difficulty: 59,783,368,655 (+4.96%)
Adjust time: After 1579 Blocks, About 10.9 days
Hashrate(?): 416,276,506 GH/s
If we go under 5 this week I will consider it a win. The raise in BTC is nice. But these new machine's are going to hurt it looks like.

Obviously, this is boards problem.
They are sometime overheated and now we have some chips with poor contact.
My recommendation. Turn the controller to the other side, so that data cables can be exchanged. It is only four screws, at Controller metal frame.
Check , the error is repeated on the same blades or not.
Come on, i would know if the problem it's the controller board im talking that 22 miners from different batch do the same thing! and people here come and say to check the PSUs.. it's like they are not reading what i typed..
What are the odds that me and my friends have bought 22 miners with the left BOARD with problems???
I think this must be a tad exaggerated. Just the chances of 22 miners having same problems are slim. Did the same person setup all of these miners? I read the PSU's do you have any that are a little bit higher quality? Those are all ok... none great. But I suggest posting some networking screens, status screen, etc. I think 22 miners something chances are something was set wrong. |

but looks liek I have ot settle for some Antminer S7's instead.  No, you don't have to settle for an S7. Do the math. You are unlikely to ROI before the block halving. Better off buying BTC and hodling while it's 1BTC < $250 USD, IMO. +1 Bitmain and some customers calculate ROI with suggestion the difficulty will not change  https://bitcoinwisdom.com/bitcoin/difficultyheh with the current difficulty rise likely due to KNC bringing up its 16nm chip run for their large world class data hall in iceland and bitfury going to do the same in probably 2-3 months in that they've taped out their 16nm stuff...this 5% diff rise could be a pretty good constant for the next 4-6 months ....trying not to be dramatic ..but it kinda looks ugly if my guess above is right The ones that calculate with no change are dreaming. Some claim when new gear goes online old gear is going offline. But I have found old gear normally does not go offline but to a cheaper electricity area. This week I think a min of 5. But guess we will see. We are going to have a few pumping out gear though. |

this can be done into a rig of 4 of them like 18 TH and its just 5000$ and the roi will be like 267 days then can be deprecated into 1000$ sells of them all just a 1000$ profit can be like it no?
90 day warranty ..after 90 days she blows that is 1882 bucks gone poof imho.....difficulty is shooting up with knc 16nm chips flowing into their large data hall now......also bitfury 16nm just said tape out so figure they will take over the pump when knc is done then same diff rise poka...looks to me like we could be seeing above 5% diff for the next 4-6 months per pop or more just saying it looks ugly It is looking bad on difficulty. Guess we will see over next few periods, but I sure liked summer mining with low numbers. Looks like this winter will be interesting. Also on warranty I expect they ship a paper and send a email of way's that violate it. If you don't follow rules the warranty goes away quicker then 90 day's. So overclock or improper power .... no warranty |

Am I the only one whose rate is fixed regardless of consumption, the time of day or month of year? I also don't have any added transmission fees and such that a lot of folks talk about. This applies to both my house and the shop, which have different providers.
Could be a Midwest thing. I also am flat rate no transmission fee or summer/winter rate. Does not matter what time of year it costs me the same. I had a few locations in Midwest all this way besides student housing. I sent you a PM aswell. |

Well, look like opening guessed are betting pretty high. I guess betting for negative isin't going to take us anywhere for a while. I was hoping this wouldn't happen before S7 actually got out.
It is likely S7's are being made now. I would guess they first go into bitmain's data centers in places were they sold S5 used units. Then eventually the S7's make it to public hands. But I think internal will be first priority for them. |

Not great news as we likely will never see any KNC chips in hobby miner hands. I think this will be internal but guess we will see later down to road. Next is SP, Innosilicon, who know when they start making machines with newer chips. But that with bitmain is at least four chip makers all who will raise the difficulty... hope it spreads out some at least. *Edit KNC has fell back quite a bit from that pic they showed https://blockchain.info/pools |
