I wonder how many miners who hop to a pool which has just had a good run of luck will also go out and buy a lottery ticket using last week's winning numbers?
LOL I agree! I tried some different pools to see how they compared to slush's. They all have their pro's and con's but find this pool to be easy to understand compared to others with the chance of having goods days when the luck is good. |

Round 21007 paid normal for me.
My biggest concern is that it was nearly 8 hours.
Blocks are supposed to be an average of 10 mins.
The average here is more like 2 hours. That is 12 times slower than average.(over the last 30 rounds it was 65hours 31mins, that is 2hours and 11mins per block)
I would like to mine on the other pool that is running at 12 times faster than the average. Does anyone know where it is?
Its all in proportion to the hash rate of the pool. Blocks are found on average 10 mins on the network not per pool. The larger the pools may find more blocks but you will receive less per block as you would in a smaller pool. I have tried 4 different pools and like slush's pool best. EDITED: But even the big pools will get stuck on a long block... its all about the luck which over a long period should even out. Block #21035 which we just found was done in 55 seconds! |

I am usually on the short end and only a few times have had the wrong amount go it this direction but those few times it has always been readjusted as I am sure that is what will happen this time. |

Those days are long gone. I just sold all my USB miners last week on EBay for $24 each. But the resellers always have sold them in BTC so even if you take Canary's last price of .035 and todays price of BTC you are still looking at $28 each. I am thinking ASIC Miners could do another run of these and be able to sell them out easy.

I have been a seller on EBay since 1999 http://www.ebay.com/usr/playlikeachampionI have seen and been thru a lot. Now EBay wants my credit card so THEY could make refunds to buyers with the CC. Last week I wanted to sell my USB Miners so I gave EBay one of my CC and listed my miners. Once they sold and shipped I froze that CC. I really don't mind taking care of a problem if one comes up and always have been more than fair in the past, but not sure I like EBay just handing out refunds as they see fit. Also with PayPal I have my account there ONLY linked to that same CC. Never again to my bank account. My PayPal account was hacked years ago and have seen to many horror stories with charge backs and have done a few legitimates ones myself. If most people understood how venerable they are as a seller with EBay and PayPal they would think twice. I always pull my money out as quick as I can and it seems instead of "buyer beware" its more like "seller beware". |

My single will run at 58.8+GH/s and over the coarse of 12 hours it will start to drop off slowly down to 57 +/- all it takes is a quick restart and it goes right back up. Now I did have problems with the hash rate dropping off in only 4 -6 hours ( drop to 55 ) while I had 70 USB miners running on the same computer. Over 12 hours then I would see the miner drop as low as 45 GH/s. So I sold the USB miners off and just run the BFL.

I left it off longer this time.... now about where it was when I unboxed it, but still half of expected. I'll let it run for now until I can get a smaller hex bit.
BAL 1: max 56C 3.26V | 25.59G/25.49Gh/s | A: 453 R: 61 HW: 4 WU:339.7/m
i think there has been reports of fans either coming unhooked or not working. I would pull cover off and check . Also make sure both power cords have power. |

I just pulled another 50% of my Slush hashing power because these long rounds are making me sick and slush is no longer interested in monitoring my hash rate properly. I'm seeing what others are noticing, a slightly marginal (20-30%) drop in hash rate for no apparent reason.
have not notice any drop in my hash rate? It even seems the miner auto diff is better than what was at first because I don't get the wild swings in it that I did at first. |

When I start my BFL up I get 58GH/s and it will run steady like that a couple of hours. Then it starts to drop a slow steady decline over the next few hours into the 40GH range. If I am around I can restart the easy miner program and have it go right back up to the 58GH. I have it set up in the basement and would not think it's a cooling problem? Just wondering if anybody else has seen this?

Holy Crap, 100 TH!? It's been awhile since I looked at the subject. That's a lot of hash.
That is an old number. The pool is at 270+ TH right now. |

You need to balance the load between the three outputs.

Can one of you show how it's hooks up?
I second that! I put up a blog a while back as I was getting to many messages asking about using PSU to run hubs off of. http://aurel57.blog.com/2013/09/29/asic-miners-usb-powered-hubs/ I use 20A 5v PSU's to power 4 hubs running 28 USB miners. (A person should be able to power the 49 port hub with a 40A PSU without over stressing the PSU.) My first 20A PSU has been running a couple of months without problems. Since I have added 2 more PSU's and have 10 hubs running 70 miners now running. The wiring is pretty straight forward. For the 20A PSU I bought a cheap power strip that had 14 gauge wire and cut the cord off. This is wired to the line +/- of the PSU. If using 110v wall outlet make sure your PSU switch is on the 110v and not the 220v as most have duel power. Now on my 20A they have 2 output ++/-- this is where you will power your hubs from. Since I wanted to run 30 USB miners from one 20A PSU I used 4 hubs so I could wired 2 hubs to each side of the power to balance the load. On a 40A PSU there is 3 +++/--- outputs. Without a 49port hub its hard for me to tell just how to wire one of these 40A PSU so the load would be balanced on all 3 outputs. I hope this helps some. Here is a close up of the 20A wired to 4 hubs (I added a cheap led volt meter as to keep a eye on voltage)  |

philipma1957 has found this PSU: http://www.mcmelectronics.com/product/58-12860 use code afc909 get a 15% discount to under 14 bucks plus shipping! It should be tested Wed/Thur to know for sure, but from the specs, it looks to be a great PSU to power one of these hubs (for the $). I blew up a pair of them at about 30 sticks what blew? the PSU, the wire or the plug? Its says its to have 36amps on the 5v side so should have powered more than 30? |

I doubt it affects any other pool. Based on their post, I'm guessing 50BTC in their infinite lack of wisdom did not invalidate previous jobs, or did not set the difficulty (payout rate) on a per-job basis when a miner changed their difficulty. This would allow a miner to store up high diff shares (not submit them), then regularly alter their difficulty on the pool interface, and submit them for more credit at a higher difficulty. It's a completely obvious exploit, but the description points to this scenario.
Fun fact: I did the math on how much extra payout you'd get on a pool with such an exploit. I think 50BTC's limit was diff=512, in jumps of powers of 2. So 1,2,4,8,16,32,64,128,256,512, 10 different levels. The formula for how much extra you'd expect to be paid on a power-of-2 difficulty adjustment system is: (# of difficulty settings + 1) / 2. So in this case, a person exploiting a manual difficulty adjustment with 10 different levels would be making 5.5x more than they should at a given hash rate.
The luck part isn't a mystery. 40% and 120% days aren't even close to unusual. I think they were too used to controlling a massive portion of the network, so when they became a relatively small part, they were caught off guard by how much daily variance you see.
eleuthria I wanted to thank you, I always value your information (even on competing pools). |

 new diff is 390 million ! Who cares about the difficulty when you have the pool luck we are seeing!  |

Red and black wires should be the 5v and you can get a barrel jacks to hook it up to the hub with. Just watch your wire size going to the hub 6-7 USB miners will draw 3-4 amps. I have the barrel jacks here on a blog if that helps. http://aurel57.blog.com/ |

Comparing your fraction of shares to Total shares to mine, there is clearly a lower value for this block, perhaps your rig or internet connection had some issue towards the end of the block Block # Share ratio Aurel57/Kabopar 20474 1.649844452 20473 1.22581721120472 1.936893204 20471 2.221506761 20470 2.186536019 Yes I think that must be what happened. I had noticed the big drop in shares as well. According to the ratios, the drop had started during the round 20473, and continued to round 20474. The latter round's reward may not have been affected, as the dropout only occured in its beginning. The former one, OTOH, has been ruined completely, as the dropout covered its end. Yes I have been watching and now see my phone company must be having issues as I have loss internet a couple times since. Loss it for 5+ hours last night (at least it was over that 5 hour block) The miners start back up and its hard to know what happens if you don't catch it. I am mining with 70 USB miners at about 23.6 GHS  |
