So an overpriced solar panel with overpriced li-phos batteries that will only last two years and a nifty looking USB hub? Really people if you want a solar powered USB hub you can slap one together with ease. You can buy solar panels with charge controllers for less than $1 per watt now, get some car batteries and a power inverter and use any gear you want. What's the situation where someone needs this and it save them any money over a power bill? Stuffed full of the most power hungry USB asics, it will barely operate, the batteries wouldn't last through the evening so it needs to be plugged in...
At least his batteries will last two years. A car battery won't last 2 months in a deep cycle application. 12v inverters generally suck for efficiency. I don't argue your main point that it looks a bit overpriced for what it delivers but hey, people will pay for a Prius to increase their carbon footprint while telling themselves they are helping it, so why not this product. And besides, you clearly don't understand any of the engineering issues you need to solve to run a solar powered rig. Now, ifen you had said "golf cart batteries" it woulda shown that you a) know the difference between starting batteries and deep cycle batteries and b) know the cheapest deep cycle battery on the planet. Bonus points woulda been given if you mentioned the need to provide ventilation and store them away from fire or flame. Car batteries would work as long as you don't discharge them more than 10-15%. I really want to get my hands on one of those ~300v prius batteries. Also, Hydrogen in closed spaces is awesome, where is your sense of adventure? |

You should be getting all signals from the GPU with the USB risers. I've had a few cards that didn't always do it, but the gpus were usually on the way out.
Same, I use that exact same riser and have no issues with temp readings. Usually you will either get all or none, because it shares the data channels for the whole operation of the card. If you can mine with it, the riser is almost impossible to be the problem. I do remember you need a modified cgminer for the temp display to work with 290s. |

I notice the antminer u1 is significantly more efficient than the antminer s1. Does anyone have a solid explanation for this? I know the s1 controller uses power, but not that much!
Is it just the difference between the conversion of 12v (s1) vs 5v (u1)
Or perhaps the density of the chips to each other vs a single usb?
Does anyone have a slew of them on an externally powered usb hub that can verify readings at the wall?
yes and you are correct they use less power per gh. but they cost a lot more up front. all power is due to the resistors used in the u-1 they send less power to the chip. an s-1 has 64 chips = 180 hash 90 u-1 have 90 chips = 180 hash if you buy an s-1 it is 1.11 btc and a good psu = 100 usd for a platinum total is close to 700 usd for 180gh burning 360 watts 90 sticks are 2.7 btc plus 2x 49 port hubs are .3 btc = 3 btc or 1860 usd lastly 2 good psu's run 200 total of 2060 usd for 180 gh burning about 280 watts. I had 45 u-1's with a plat seasonic the used 3.1 watts so to save 80 watts an hour for the same hash you spend about 2060 vs about 700 usd. all testing done with k-watt-meters u-1's have a place but if you have money s-1's are far better cost wise if you want a usa seller https://www.minersource.net/has a kit with 2 s-1's and a good psu https://www.minersource.net/products/bitmain-s1-dual-blade-180gh-400w-asic-miner-1-2-3this is a better deal then u-1's will ever be. Note you can buy direct from china and source your own psu and it would be a little cheaper. but may take longer to show up and longer for rma's I purchased direct from china and got 1 dud out of 4 purchased. I am not looking to purchase, just a wandering mind. I already have s1 units and love them. It would appear from your measurements and chip count that the u1's are only more efficient because they are clocked slower. One could simply underclock the s1 to get similar efficiency levels. 80watts might not sound like much but it is almost 30%. It could mean the difference between shutting them off or keeping them alive for a couple more difficulty changes. Like I said I am not looking to purchase anything just curious for verification of the actual w/ghs. |

is it?
S1 is 2W/GH at Wall, U1 is 2.5W/1.6GH at USB
so you have to add the Hub/PC PSU efficiency
The hub is going to be 99.9999% efficent. The only thing that is in it is a bridge IC (or a few depending on the size of the hub) Yes the power supply efficiency would come into play but would be the same efficiency running an s1 or u1( I assume the power supply efficiency doesn't vary much if you are drawing the 5v or 12v.) |

Does any profitable mining hardware exist that is available for purchase and delivery now?
Bitcoin mining - ASIC mining equipment (Antminer S1, KNC Jupiter, Avalon) Litecoin/dogecoin/alt mining (scrypt) - Multi GPU setups using R290X When shopping, you'll want to divide cost by speed (in gh) to figure out the lowest cost per GH. If a site sells in BTC, convert to BTC if you're planning on exchanging BTC for fiat. example: $750 / 180gh = $4.16 per gigahash The lower dollar you spend per GH, the better. Good luck, be wary of "too good to be true" deals. My advice is to stay away from group buys. Thanks for your advice. Yeah, I don't want a group buy. I want some hardware that I can run myself. I had a neptune on order but cancelled as things got too FUD. I also didn't like the idea of not receiving my machine.. If you were buying, right now, and had a few grand to throw down....what would you buy? Antminers or gpus. Dollar for dollar the profit is about the same right now between the two. The gpu rigs will consume more electricity, but the scrypt hasrate is not increasing at nearly a rapid of a rate, and the gpu rigs are less likely to become obsolete as quickly. The antminers use less electricity, but the difficulty is rising fast on the sha currencies and the antminer is more likely to become obsolete more quickly. I wouldn't consider anything else. bitmaintech.com for the antminers, or the usual computer hardware sources for gpus(or you can buy prebuilt rigs on the forum. I have some for sale 6x r9 270x and 6x r9 290 ) |

You forget to mention that some Sotoshi are far more rich than other Sotoshi...
That is a GOOD thing. |

WE are all Satoshi Nakamoto. Each any every one of you!! That’s the point of bitcoin. If you are holding or if you are mining bitcoin you are bitcoin thus you are Satoshi Nakamoto. You will never find the creator of bitcoin. That is the point to the whole thing. Satoshi Nakamoto wanted us to all come together and own bitcoin. No one to govern nor anyone to control bitcoin. Bitcoin lives inside each one of us. In our hard drives hosted on our internet . Bitcoin was powered by the people .Not gold or silver or scamy start up company with cheap stocks. The wealth of bitcoin is within the people. If you really want to find Satoshi Nakamoto go to the mirror and there you will find him. While you are in the mirror pat yourself on the back because you are a part of the revolution of finance and banking for our species. In 30 years the systems of wealth and our systems of monetary value will live in crypto.
I understand the concept that you are illustrating and agree that is the point of bitcoin, however I feel the search for Satoshi is not because he is bitcoin, but because he had the idea and took the effort to create something so great for all of us. |

Must be your version of Wyoming. When I lived there, the running joke was that every place has four seasons. In Wyoming they are, Winter, winter, winter, and fucking winter!
Nice place for a misanthrope, though. Soft people don't live there. Not very long anyway. They either get hard, get killed, or get out.
No joke. I thought Nebraska was cold until a friend of mine sent me a picture from Wyoming standing on an oil derrick holding a thermometer that read -31. Not wind chill. -31. They joked that Wyoming madness was having thicker clothes than they had length of wiener. |

right now if i boot into window with a 290 and a 280x the 280x shows up as a generic vga in device manager
i manually install driver and it says successfully updated to r9 200 series
i got to device manager and it shows r9 200 series (my 290 which works great)
and the 280x shows up as a hd 7900 series and causes all sorts of crashes
i think i might need a fresh install of windows. will try tomorrow
Fresh install is alot easier that screwing around trying to remove drivers. If you plan on installing more than 4 cards at a later time use the modded driver. and then mod your catalyst installer, then install the catalyst. (some people say that you can just use an older sdk rather than modding and installing catalyst installer, but I did it just the way I described and it worked perfectly) |

Yup ...right below this thread we have Leah McGrath Goodman offers more details on conversation with Dorian S. Nakamoto And because you didnt even read the damn news .... you were so eager to post .... Maybe you're "gifted".... i'm deeply sorry then. Of all of the information from the interview, why is the reporter something worth remembering? The name of the person who conducted the interview is the last thing on my mind. Now that I know who you are talking about the statement is obvious. |

Then you're a perfect target for Leah....
"If you've always not been stupid, you have to tell me NOW "
Yup, you're guilty until proven innocent
Who is Leah? and how is it relevant? Should I expect her to attack me next? omg you just take my proof to a Whole 'Nother Level .... Yeah.... no doubts at all that you're beyond stupid. We dont need Leah.... Because I don't know who Leah is? Because I couldn't decide if that was a statement about an individual that enjoys berating people for alleged stupidity, placing the burden of proof on the accused or some sort of third person retoric that the hipsters think is clever or some sort of catch or insult that I am not privy to. |

You guys are all assholes. I assumed something like this would be at the top. But it wasn't. When I continued looking and found several other postings, the forum wouldn't allow me to delete my post.
I also find it interesting that you challenge my intelligence based on one post, that I thought was pertinent information. Do you have insecurities about your own?
My advice to you: stop opening your mouth and remove all doubts now the world knows how dumb you are....:facepalm What if any evidence stupidity have I provided? That I failed to do a thorough search? any one with half brain would figure out what the titles of the current threads in this section are about. "..clearing name.." etc.... A dumb one however need to see " Satoshi is found! Breaking news " right on top .... You did remove my doubt with the previous post You make a good argument, I can't tell you exactly what was on the front page, but at the exact time I posted their was nothing incredibly obvious. (Satoshi is found! Breaking news) I suppose I was blinded by the excitement. I still don't agree it is evidence of stupidity. I don't consider myself stupid, but I really cant present any concrete proof of the opposite. |

That is exactly what I ended up doing after digging a little deeper. The correct package on that page (for anyone who might need this in the future) is LINUX driver for kernel 3.x and 2.6.x and 2.4.x I'm running bamt 1.3 but first you must do this... you need to blacklist the old module. try this:
Code: [Select]
echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist.conf taken from https://litecointalk.org/index.php?topic=2924.msg75706#msg75706works like a charm now. for some reason windows would become unstable with my second card and smos has been pretty good to me so far. (great now I have to register there just to say thanks)  That is surprisingly backwards of my experience. The first machine I build ran 6x gpus on windows like a dream. I tried to switch to bamt to reduce overhead. Didn't work. Ubuntu runs great but I am not sure if I really gained anything. |

bring back the newbie section.. ppllaasse
satosi made bitcom... tis lgit
Yep, You found a typo, Congratulations. Because of that missed key nobody on the forum knew what I was saying and my goal of relaying information failed. Nope they actually got the point quite clearly, and the missed letter is irrelevant. |
