Sorry you guys need to close. Thankyou for all your hard work. shame just need the pool to find a block before I got paid and I don't blame you the difficulty is too much right now for anyone except antpoool and f2 who strangely own most of the blocks.
Ditto. For posterity, I preserved EMC's final home page on Wayback http://web.archive.org/web/20160329012206/https://eclipsemc.com/Every time I ran payout comparisons between EMC and Kanno or Antpool, using PPS on EMC was always marginally better than the Other Pools when looked at over several weeks of run time on them. Kano is now my main pool simply because they only have to find just over 4 blocks a day average to match what EMC paid me per-day come rain or shine. Problem is that a couple weeks ago I finished another 3 week run on Kano and once again they fell just under that average. I of course moved back to EMC until today so now it's back to Kano. For me Antpool is failover #3. Using PPS (2.5% fee) they pay a bit less than Kano and I refuse to use F2pool or Discus. |

 I'm going to miss them. EMC has been my main pool since I 1st started mining in Feb. 2014. We had a good run with me ending at ~96.4THS there. Guess me being almost 1/8th of their pool and running PPS along with it now over 26 days since they cracked a block broke their back

Help Me Please
Do I want to know, How do jumper Switching HP DPS-800AB-11A
Thank you very much.
<snip>
Most server psu's require a DC on/off switch just as Bitmains now do. On the HP's, see the group of 6 little pins? They are the status and control pins. To turn the DC output on/off connect a switch or jumper between pin-1 and pin-4. When connected together the Dc is ON. ref https://i.imgur.com/3RL15ui.jpgmy control wires are the black and brown ones to the left on the small pins. |

This is just an amazing project!
Can't wait to see/buy the final product.
yes I held off filling the solar array. we have 13-16 k-watts of power for mining and right now I have 7 avalon 6's marked for it. 2 actually running 4 in my garage and 1 on a ups truck coming to my home as I type. so that is 7 kwatts this means buysolar and I will be looking to add 6 to 9 k- watts worth of this gear. We are hopeful that we will have 22th avalon + 60th bitfury = 82th By July 1 Damn you... Now you have me looking at solar at least at home to offset my miners here (now ~3.9kw). At 15-cents/kWh - ouch. Just got the bill for last month when I was running 6.5 kw of s7's here (for winter heating ya know), um we had many days over 65 here so my AC had to run to keep the house below 80F. $1,054 worth of owwie there... The upside to that is I think my furnace only came on 2-3 times over the winter so normal heating costs for the gas & electric to run the blower were near zero. In looking around just found http://www.ecodirect.com/ who carry tones of goodies and - they take BTC.  Panels, inverters, controllers, LED lights, you name it. Methinks I'll peruse their wares for a bit... I like the micro-inverter idea 'specially since they output 240VAC and prices look rather good. Hmm... |

i have a problem with that fella and his "power wall" there is no over/under charge protection to any of them 18650 cells fuse wire is OK for killing off shorts, but its no charge protection, now, all them cells packed in that small place, i can see a chain reaction happening when one goes off, he didn't want his house did he? Sounds like the DreamLiner battery fires waiting to happen at home... Using salvaged Li cells from eBay?  oh good god... unknown (real) makers and true ratings vs as-marked along with unknown lifetime left in them... All makes for a safety and charging nightmare! |

Say, got a question. Who's the best domestic quick-turn prototype PCB fab? We've gotten prototype PCBs made by SEEED, but they're in China - which is grating for obvious patriotic reasons and because it makes shipping suck for any kind of speed.
I use http://www.pcbunlimited.comTheir Panel share is ridiculously cheap for prototyping if you can wait 5 days, but their quick turn is not too bad either. Panel Share would be good for controller boards but the restriction of 1oz copper makes it a no-go on hashboards. |

I've always used Sunstone Circuits http://www.sunstone.com/pcb-products along with their PCB123 software. Home for them is in Oregon and with turnaround of 24hrs (if ya pay for it) or a week production has to be in the USA. Great company. |

I didn't put PCIe plugs on my boards because I don't like being limited. A good solid screw terminal, well heck you can put whatever you want on it. And cables are cheaper too. Unfortunately people really like to have things quick and easy these days, instead of good and flexible.
100% agree. With screw terminals cables are a lot cheaper. You can cut the cable the length you want. No need for flimsy molex tools to built them. His way is good it actually stays on the board , the other screw way does suck sadly, i have one those boards and don't use it . but do use the one i bought from him from a third party, if i need the PSU that low like a S1 etc , i have one of his low end boards and I like PCEI plugs more and yes because it is fast easy sometimes fast is better sometimes it's not. , just wanted to make sure it wasn't some kind of safely issue, he knows that stuff pretty good. why i asked . I use this http://www.amazon.com/gp/product/B007JLN93S?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00 for 23 bucks it's not flimsy doesn't have all the bells and whistles the 100 $ + has but i also don't need a big high dollar one either . the one i linked is really good for what i need. it will do 14 weight wire even thu it says 18 in the add. That is a pretty damn good price for a real crimper! Wonder who makes it and if they have other jaw inserts available to do terminal lugs, coax F-connectors, or RJ's? |

Rather wandering off the thread and getting distracted here though...
On yer Block Erupters, my first 2 miners were BFL's lil' 10GHs Jalapeno's. Loved them and those 2 bastards got me hooked.... Still have them but long off line because that 10GHs takes 60W each. However... pop them open and ya see 10 or more spots ready to accept ASIC's. Believe they can be retrofitted up to around 30GHs per now super-hot Jalapeno...
CGminer would not work with them but BFgminer runs them perfect. Perhaps try it with EMC and the Erupters.

As I said, my main pool for the next week or more is now Kano so they get a good average payout/THs applied for at least 3 weeks. Kano hit full payouts for my 5n work there last week so windup is done and payouts are pretty consistent. Still have the Kano miners set to failover to their EMC home. Handy when Kano resets... Last was 3 days ago and 30TH shifted to EMC for 3 hours. Payment for shares ran immediately applied to the running total until trigger is reached. Also keeping 15THs running on EMC to track their average over the same time as Kano. |

Oh and you should switch to kano.s, it's a much better pool.  I have my main hash on Kano and my Compac's and such on Bitminter. By the way, the are a lot of pools that have payouts equal to or greater than Kano (except the last few days which have been crazy lucky).  I know this is going to start a firestorm but... Eclipse Mining Consortium https://eclipsemc.com/ is excellent. Leaving the BFL matters aside, they have been rock-solid for me since I started mining back in Feb. 2014 They have always been a small pool, current hashrate is 907THs. Yes their PPS plan charges 5% but - you get paid for every share ran no matter how long it takes them to crack a block even if it turns out stale or invalid. Hash rate applied is revised every 15min with the new rate immediately applied to your work and full new hash rate being shown in 1hr. No '5n windup'. No waiting for payment per block cracked and verified. If you have an EMC account, payment is upon the running kitty hitting your chosen payout trigger, in my case every 0.2 BTC. Kano and Antpool are PPLNS meaning you are paid by average hashrate covering 5n shifts with payment only after the found block(s) mature. I have ran comparisons with them (Kano and Antpool) against EMC a couple months ago and looking at payouts once the PPLNS windup is out of the picture and payouts are stable, given 2 weeks or more run time on the pools EMC has ALWAYS come out ahead by ~ 5%. However, as kilo mentioned, Kano has been doing exceptionally well for the past couple weeks. Right now I have ~71TH pointed there and will be doing another spread sheet on the long-term results of Kano vs EMC again. |

Current rating is too low, we require 25A minimum with 30A (for overclockers) as ideal. Also cartridge fuses ( eg. any AG or SFE) suck at high currents, biggest problem with them is the contact areas on the clips and cartridges, get the slightest bit of oxidation and problems start happening fast.

Then the question becomes: Did PH miners actually buy rights to use the image or just copy it off the Getty site? Betcha Getty would like to be aware of it's possible/probable unauthorized usage by them... |

"Shortly"- To occur in many many months.....maybe 2 weeks! LMAO,I forgot about that BFL reference Rather surprised AMT/Bitmine.ch are not always included in that. eg AMT/s ad in Oct. 2013 for the A1 520GHs miner http://web.archive.org/web/20131003021440/http://advancedminers.com/bitcoin-mining-hardware/520-ghs-bitcoin-minerLove the "Order placed in September ship in November". No hint of any pre-order unlike the 1.2TH rigs so I ordered the 520 late Feb. 2014. We all know how their A1 debacle/scams went...  At least BFL actually produced Monarchs. Problem was getting them to let go of them and placing them in customers hands... That said, I and a very few other folks actually did get something from AMT. In my case what appears to be a very well made LKtek 1.2THs rig along with a PSU for it. Many of the few shipped were sans PSU... Almost 8mo late but better than most folks that got zilch from AMT along with those that Bitmine.ch shafted as well with the Coincraft A1. No doubt Josh arranged those during his stay in Shenzhen trying to scare up someone to make working A1 miners for him. And yes the miner still is perfectly running in our break room 24x7x365 for heading on 2 years now. |

Nice put in a 25 amp blade and safety all around. Yeah I know the tweakers will want to put in a 30 amp blade but still make spec with that socket. That is also a troubleshooting technique called "smoke testing". Put in too large of a fuse and see what smokes. Then replace it. If the larger fuse still blows, replace with larger fuse and repeat. Nah. Fuses cost money. Just make a jumper and let the PSU or wiring between it and the load be the limiter...  edit: Hmmm, along those lines, has anyone looked to see if the IBM PSU's have an internal adjustment to set the OC limit? |

I am not surprised with new batch I expected they would. This batch could be open longer they word it " Shipped out from March 15th" so they can really leave it up for a while until they change price.
And wow ... considering prices in past it is amazing how low these things are going now at least to me.
I assume the low low price is mainly because Bitmain recouped all of their R&D as well as production setup costs around batch7 if not earlier. Now pricing is based on what the market will bear and their cost to produce is just parts & labor/other overhead. Add in profit margin - I'd guess is still >100% - and you have our costs. The latest price drop is 'prolly to entice the fence-sitters to buy some more s7's while they are waiting on BitFury or Bitmains next gen rigs. With them at $650 USD I'm seriously considering getting a few more s7's myself... |

I agree fusing is a good idea. Definitely go for automotive blade style vs the cartridge fuses. They have currents up to 120A. Far more reliable and smaller as well. Wikipedia has surprising good ref on them. https://en.wikipedia.org/wiki/Fuse_%28automotive%29 |

This is a very grey area.
In the Guardian article they say "If you use your debit card to load your PayPal account and then use that account to make a purchase, you are unlikely to be able to use chargeback if there is a problem with that purchase."
Grey area there is the words 'PayPal account'. Problem is that PayPal has changed from just a load & spend service (requiring a PayPal account) to also being a credit card transaction processing service for sellers that I assume acts as a go-between for your credit card and the retailer. That is where the Third-party wording comes into play.
The Banks/credit card companies want to/will only cover you if the transactions are done directly through them. They look at the matter as if you had a PayPal account that you xfr'd funds to for making the purchase. To them it being a 'real' or temporary account is not in the equation. Ergo, disputes regarding usage of funds in that (PayPal) account is between you, PayPal, and the seller. Not the Banks problem.
Bottom line is that various countries laws aside it depends on what biz agreements PaPal has with the various banks/ credit card issuers.

Just a little niggle on "Non boiling fluid provides little convection fluid flow, thereby leaving hot fluid on/near the surface of the chip. And even then, the fluid didn't boil." In a fairly open system yes. In the vids BF shows it's a safe bet that the tank of Novec is near ambient temp hence the lack of phase-change seen. Still pretty impressive as ja that shows that the power the chip is dissipating remains rather low. In a densely packed system with 1-2 cm between the boards like BF's data tanks have thermal siphon effects kick in that will created a surprising amount of flow over the boards & chips. With Novec's very low viscosity that should translate into a pretty decent amount of flow circulating over the boards and back down the sides of the tanks. Once the whole tank of fluid gets near the boiling point then it should get quite lively in the tanks. That is provided the non-insulated data tanks don't already have enough outside surface area to keep the Novec below its boiling point. Doubt that is the case. If it is they'll just pack in more chips  |
