True. Gridseeds have been the worst purchase I ever made in crypto.
Block erupters weren't exactly awesome either... what was your experience with the gridseeds? I almost bought some when they 1st arrived on the market. The big hype initially was you could mine both scrypt and sha256 with them, at the same time, so you'd be able to mine both ltc and btc. Well, technically true but very hard on the devices. They'd burn out after a few days and be heatsinks or novelty paper weights for a desk. Switching to just mining scrypt with them so they'd last a while means they run on very little power but also produce very little return. I've had 17 running for quite a while and they produce on average just over $1 about every 4 days on westhash. This of course means the thousands of dollars I spent for those 17 will never be recovered. |

Not trying to attack bitmain at all. I did a lot of research before buying, and they had the reviews I liked. As far as my troubleshooting, you sound like my buddy. He said I just got unlucky and got bum units. Me being the optimist was hoping it was because I was trying to be cheap on PSUs. As far as asking for advise after 1st one I've read the responses most have and figured that wouldn't do me any good.
It looks like you didn't post the brand name or manufacturer of the power supplies. That can make a huge difference in getting help and identifying the problem. You need to see if the power supplies will work without any load on them. Use the paper clip in the motherboard connector method (examples abound, do a search for the details) and see if the power supplies power on at all anymore. If they do, use a voltmeter to see if it produces 12v on the required pins in the different connectors. Also look at the specs for the power supplies to see if the 12v supplied is on a single or multiple rails. You need single rail. Cheaper power supplies generally are multiple rail which will cause you problems. After you determine if the power supplies will power on at all, then open the S3's and see if there are any obvious burned components or traces on the printed circuit boards. It sounds like the power supply leads/traces may be fused into a short and that may have popped/trashed your power supplies. If there is any obvious internal damage open a support request with bitmaintech and work with them to see if it's a warranty repair or replacement situation. Just a word for the future: you're spending lots of money on a piece of equipment... don't scrimp on the power supply to run it, especially when sellers such as newegg.com have perfectly functional power supplies for reasonable prices and frequently offer rebate or discounts that make the power supplies even more reasonable in price. Look for at least a 500 watt power supply with the 12v on a SINGLE rail, not multiple. For a comfort margin and to operate the power supplies more efficiently, you may want to get a minimum 600 watt power supply. Just as a personal preference, one power supply per miner and I generally use CX500's or CX600's or even CX750's, but not the modular power supplies (they generally have 1 pci-e connector and you need 2 or more if over clocking). If you power multiple miners off a larger power supply and it tanks, you have multiple miners out of service. Yes I'm aware of this. The first 1 was a power supply claimed from an ancient computer. The 750 was a CHIEF MAX 750. I returned that. The 1000s were Kentek. I am not sure what happened to the first, it just smoked and stopped. But the fuse was good. The second one blew a fuse, so I unsoldered the good fuse but that went as soon as I plugged in with no load. So those ones are no good at all until I can get new fuses for them. As far as opening the cases, I did that and everything looks fine. Nothing visually wrong at all. I even went as far at to test for continuity in all the cables, very tedious. As far a Bitmain I am in contact with them. But progress is slow. I now have a modular PSU so each blade gets it's own rail. Also, The one that blew the three got so hot there's still pieces of the pin glued to the connector. I tried using both controllers in each miner and the results were the same. Nothing. I'm not sure if I should be asking for new boards or whole new units. I just want to mine some coin! Hmmm. I wouldn't be using any of the power supplies you've noted. As to the miners themselves, this is probably the first instance of power connectors melting on the miner unit itself. I've not read any postings saying so, but of course I've not read every posting in bitcointalk either. I'd suggest working to get replacement units. Something overheating very badly caused the miners power connectors to melt. Bitmain should be interested in the forensics result on this one. |

folks I have 2 1TH/sec Dragons with factory installed software. How much I can get per day on your pool approximately? thanks
See https://www.nicehash.com/index.jsp?p=stats . Current profit : 0.0122 BTC/TH/Day. ~~MZ~~ Not current profit. Gross income. Gross income - operating costs = gross profit. So 0.0122 btc/Th/day - electrical cost - bandwidth = gross profit - other costs = net profit or loss. Don't forget the cost of the mining equipment = - $ Company that you bought the equipment from made 1000% profit. I've been through it and made nothing with scrypt miners. True. Gridseeds have been the worst purchase I ever made in crypto. |

Just wondering, since these things run on 12v, has anyone tried running an S1 or S3 using a car battery?
Why? At best you'll get a few hours of a decent one and a battery will typically drop voltage as it discharges. Both of those don't really make them appropriate for mining with. Maybe to run it of an old disel engine running on some cheap (disgarded/cooking/frying?) oil...  The idea originated as an off the cuff semi-technical discussion around could you, then very quickly turned to should you. Could, yes. Should, no. For the reasons dogie cited, of course. Where's a functioning water mill with 12v generator attached to provide extremely cheap energy to run miners when you need one? Answer: Not around here.  |

Seems like there was a change in the last couple days that effected the difficulty. The difficulty for my miners has been much higher than normal. Anyone else seeing this? My S4's in the past typically had a difficulty of 4096 (even though I have d=2048). But now they are at 8192. And my 1TH/s miners went from 2048 to 4096. Pretty much doubled, for all miners. I know that overall the payout is the same, but it made the graphs very "jumpy" and at first I thought there was a problem. Actually, as I look again while typing this, the reject rate has increased, starting 1.5-2 days ago. I'm just wondering if there is an issue on my end.
I've got a few S1's and several S3's on westhash and have seen the same increase in difficulty you have, but at lower numbers. I used to see sub-1000 difficulty but all of them are now 1024 or 2048, which is not normal. So I'd guess that no, it's not an issue on your end of the connection. |

Well I'm missing one payout today... They say on twitter that nothing is lost, but why the payout of those 6 hours aren't there ?
Maybe your unpaid balance was below the every-six-hour threshold of 0.04 BTC? https://www.westhash.com/index.jsp?p=faq#faqs5..and I was really starting to get used to getting nearly twice my daily mining average - every six hours.  Yes, it's been very nice, hasn't it? As the saying goes: nothing lasts. Yeah I was smoking hot sunday until yesterday. Still higher then normal today. around 0.021 and 0.011 is normal if you mine in a pool Run with it while it lasts, is my view. When the payouts drop back to 0.011 level I'm turning my most inefficient miners off. |

One of mine is acting up (an S3) and I've set it to reboot every 2 hours:
* 0,2,4,6,8,10,12,14,16,18,20,22 * * * /sbin/shutdown -reboot
Might be simpler as: 0 */2 * * * /sbin/shutdown -reboot Thanks for the suggestion. Implemented. I freely admit to knowing just enough about crontab to be dangerous. If you implemented this verbatim you might want to confirm that your Antminer actually has an "/sbin/shtudown" command, I know mine don't, only poweroff and reboot I've had an ssh session open to the S3 for not quite 24 hours now which tells me it's not actually rebooting, but for some unknown and I don't care reason it appears to have solved the problem and the S3 has continued to hash uninterrupted. |

I know this question has been asked before a long time ago, but I can't find it anymore...
Is there a way to automatically let an AntMiner S3 reboot every eg 24 hours?
Thank you!
Go to your scheduled tasks and put this in 0 23 * * * /sbin/reboot This means my machines reboot every 24hrs at 11pm at night just before i go to bed. Regards Loki wah thanks bro this is great infos One of mine is acting up (an S3) and I've set it to reboot every 2 hours: * 0,2,4,6,8,10,12,14,16,18,20,22 * * * /sbin/shutdown -reboot |

BITMAIN:
Did your site recently change its security certificate? To one issued by a company in Scottsdale, Arizona?
Having problems logging in after no problems up until just now. Did the password reset request, got the email, clicked on the link, verified and reset the password to a new one, then got the log in page and tried to log in. Got message back saying password was incorrect, but it was the one I had just entered as the new password on your reset script/page.
I tried the log on and the reset process in Firefox and IE, with the same results in both.
I'm wondering if anyone else is having this problem, if your site has been hacked or there's a 'man in the middle' attack going on.
I had the same issue. My old password had a special character in it as well, and after going through the password retrieval process, I saw the interface had changed a bit, and there were no unrecognized logins to my account. Given I don't use Bitmain's pool or hosting services, there's only so much a thief could steal from my account (my coupons that expire in 6 days and Bitmain has said they'd hand out to anyone who wants them?). It was disconcerting though. And I wish every website supported the same standard password characteristics. None of these "maximum of 12 characters" or "0-9 a-Z only" sites! Agreed. Good to know I wasn't the only one with the issue. |

1Neptune,
Walk softly my friend. I am able to login with no issue.
Thanks. It appears to be from them changing / integrating their web site with the antpool and their system didn't like the special characters I used in the new password. |

Anybody with knowledge how to compile cgminer binary for AntMiner S3+? There are many AntMiner S3 users and it would be great to get cgminer AntMiner S3 bianry with extranonce.subscribe extension...
One of the moderators of this forum (ckolivas) is the offical cgminer developer and has published revisions for the S3, S4, etc. and bitmain adopted his modifications, if I remember my reading correctly. |

Hitler was a bad guy, and those closely aligned with Hitler were dubbed bad guys.
BFL, et al., are bad guys and if you're closely aligned with any of its principals, you're labeled a bad guy since you've opted to not distance yourself from them.
Same true for every bad actor occupying the cryptocurrency space.
That said, list names of bad actors. Also, list names of only venerable entities.
Bitmain (antminers) has been good, but looks like they may have taken a page out of the Sonny and "K" of "KnC" playbook on how to make money when your customers don't. Hopefully Bitmain will realize that customers buying mining equipment generally expect to make a return on investment, meaning something better than the equipment just paying for itself and operating costs. Running a money pit isn't done for fun and isn't a hobby either. No problem with mining equipment manufactures making a profit as they have to in order to stay in business. However the manufacturer shouldn't be the only one in the equation making a profit. </soapbox> |

Q: What do you call 30 attorneys at the bottom of the ocean?
A: A good start.
(not to knock too much on attorneys, as there are a few in the business - too few)
Good start on the list Bruno. I'd suggest having it in two sections: 1) individuals; 2) company/organization. That will make searching through the list easier as it gets inevitably longer.
