Oh yeah, I took a look at the one you shipped back and the issue is pretty bizarre. I haven't figured it out yet. The 2V reference coming out of the buck chip was reading 2.7V which was pulling the adjustment range high causing the output to pull high. The bizarre thing is I swapped a different buck chip on it and it still behaved the same way, so the issue is actually outside the chip but I don't know where. Seriously weird, because nothing else ties to that pin, the traces, nothing.
I don't quite know how the buck is laid out, but you do use ceramic caps and resistors to controls the voltage? maybe one of them is cracked and changing the way the buck is running? |

Hmm.. I might just grab a few to play with it doesn’t look to hard, even to splice in a secondary plug on a cable just for power. Are you trying to just get power from 2 usb's for this or are you hooking the little dongle or to something else for more power? You can get Y splitters very cheap on ebay. I think it was Phil that pointed these out in another thread - http://www.ebay.com/itm/221661361513?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT They are 1.45 each. Only thing is it took a LONG time to get. So do not order them if you need them quick. But order and have 2 weeks or so they are quite a bargain. The 5 I got all seem to work good aswell. So work as advertised. But but but! that's not how you DIY! yeah, OK, if you want a simple plug'n'play, go for it, but ima feed 20A to 'tem stiiks! |

New plan. Batch 2 heatsinks will now be pink.
Batch 2 is the second half of the 1000 run. Heatsinks and PCBs were purchased in quantity for the entire 1000 run. Heatsink color choice for the entire 1000 run was deliberate. I will not offer different colors because there is only one color heatsink that I have and only one color heatsink that I will be installing on any of the sticks in this 1000 run. Maybe I'll consider changing it up if we do a new Compac version with a new chip, but every BM1384 production-version Compac that I ship will have the green heatsink. The decision was made six months ago and the heatsinks were purchased two months ago and I'm not changing it now.
Which is to say, yes I have a deliberate color choice specifically for Batch 2 and it is the same as for Batch 1.
Aw, you killed our fun, we're going to bicker over the colours, then you could of piped up saying "I Haz perfect colour! This!" and show the original! At least hes trying to redeem himself xD There's probably some thermal-ok paint you could slap on the heatsink if you *really* wanted to go with wavy shades ofpink/fushia?  Hmm that sound tasty. I think i'd use a pic of that as Avatar for a while. Also; http://runescape.wikia.com/wiki/Goblin_Diplomacyyou know, dumping them in bleach would probably eat the green and blue dies..  if you haven sent mine yet, try it on one of mine, then sign it "love sidehack" Yeah |

No. Heatsinks are already stocked.
could dump them in a bucket of bleach but not to long, they get corroded .. |

If you check the very first post of this 99-page thread, you'll see an intention already stated to build boards for the S1 frame. That intention has not and will not change.
I hope to hear more info from SPTech tomorrow. Right now nothing is certain. At all. About anything. But we're working on it.
Also, it seems pretty likely that the first 20 miners sold would probably be all the budget I needed for dev so I don't really want to make deals about hundreds. We'll see when I have a prototype and timelines.
Well, as long as SPTech helps with the layout on the BGA (unless the new chipset is not?? I haven’t put the time into looking into it) and setting up the rest.. So Guy, i know you're here.. play nice with Side, he don't bite If we get a 4Th upgrade for our S1/S3/S5 chassis, then what do we do with the old boards?
I'd almost consider a buy-up on these just to do the downclock/volt them, and maybe resell them? but considering S1's are going for $35-50 as a full working unit.. If not, Marketplace/ebay them, Starting bid at $5.. there will be people buying them up I thinks.. if not I will |

Trying to install CGMiner gekko in my Raspi
sudo apt-get install build-essential autoconf automake libtool libcurl4-openssl-dev pkg-config libncurses5-dev libudev-dev
Getting this =>
try:sudo apt-get update && sudo apt-get upgrade then try itwell bugger me.. i was halfway typing this and sorting my workshop |

Already shipped back? No, the discussion is only about four hours old and the post office doesn't run on Sundays.
lol, i didn't even check when it was posted, thought it was a few days back! don't take it the wrong way, I do have interest on failures like this, maybe that's the reason 90% of my miners are dead |
|
|

...
I am assuming this is the root of my failure.
...
to me that just looks like flux residue.. already shipped back? sidehack, I'm interested in a autopsy.. |

 just to let you know, these are nasty to modify, has to get the heat-gun and iron to get the plastic potting off. |

Next My big bulk sales are past. Every small order has shipped. I'll probably have the next three bulk sales ready to ship on Friday, which includes Australia GB. That leaves three bulk sales, the oldest of which came in one week ago.
cant wait! then we all have some fun Once they arrive at my workshop, I'll photograph them, as well as packing them for everyone here  |

Show me a CPU/GPU that is more efficient than even an Avalon1 or S1.
Derp! But the 440 PH/s of hardware already exists
yes, but going by the lovely "help! my miner caught fire!!" threads or "Why doesn't my Miner work any more?!" threads every once and a while, guess what is going to disappear, especially when there is no one to make any more? just like Rockminer and their hardware, you think I could get my boxes replaced? I thought the whole idea was bitcoin not to be centralised. I thought "every CPU (miner) has a vote on the blockchain" Nah, its all there for corporations to make money and capitalise on the peasants to give them the transaction fees, just like the big banks do now all im hoping for, is the day there is no more coins to mine, only transaction fees.. just like the end of the gold mining boom, there is still hobbyists mining, big corp or 2 making enough to pay for the mining, with government subsidies, and the guys with enough money to dig their own hole with licence to mine at that premises.. but anyway, why did I call the CPU/GPU mining times the dark ages not the golden age? I dunno, less known times then? the past? before I really got into it? Still.. SPT better sell them smaller models for the rest of us, I'm happy to buy one of them blades in that case (since there is 10 of them in there, that would leave me with 11TH/s, hella better then my 50GH/s) |

im with the irritation of USB, most development skimp on ESD protection from the USB ports, so the one odd day you plug your miner in, *pop* goes the controller. simple little 0.30c protection diode would do the trick.. iirc the U3 did have that on the data lines.

Firstly, Im not sure what you mean about 11,000 years to hash a block, or how a crash in BTC would magically make CPU/GPU>ASIC.
for my 50GH/s mining capability going solo, the mean time between blocks. BTC go back to 50c/BTC, you think these companies(cloud mining/asic for btc) can support themselves? i think they will go of the ways as friedcat did. then what? no more asic been developed, then what? back to dark ages of gpu/cpu mining we go. The USB block eruptor is a pathetic device (its cute and a teaching tool, but you wont make a profit) and theres virtually no sales of it for the last several months. It simply doesn't make sense to spend $450 / 1Terrahash when you could pay only $3,500 / 10Terrahash or even $30,000 / 100Terrahash. If someone is making a profit mining a small amount of bitcoins, it only makes sense they invest more money, buy the best hardware, and GO BIG. economics 101.
yep, since all home based mining capabilities can support these industrial units (power/cooling/noise), and they have a spare $30,000 in pocket to do that. The smart layperson will buy shares/hashrate in a company they believe in (be it a manufacturer like BTCS, or contracts at a mining pool like westhash) if they wish to support bitcoin, or otherwise the bitcoin price must rise high enough that residential electricity rates can still turn a profit (while industrial miners make *even more* profit due to having the best hardware)
centralising bitcoin, perfect, company 1 has 40% total hash-rate company 2 has 30%, company 3 has the other 30%. who owns the votes of the network? drop the difficulty by dropping the total hasrate from bigwigs, more availability for home miners, they can profit with costs now. I would not be surprised if there were 50x as many customers of the SP20 as there were for the SP3x series, yet similar overall revenue due to the fact that many SP3x buyers were buying >$20,000 at a time
PS: I was watching the BTCS stock all day today, and it didn't even flinch from the news of the SP50. I thought it would jump up on the news that there is a new hashrate to sell and mine with?
yep, SP20s were not as profitable from the little people, as big corps buying up hundreds of these rack mountable sp30 hardware. but thats the problem, the little guys are missing out, bigwigs are profiting, and bitcoin network is getting more and more centralised and controlled by the bigwigs. |

...
I'm hoping they left the sp40 area for home miners or at least smaller gear. This is massive and I just am curious on the price of it. But I do see a market for it, so I can't really be mad they made a miner for the "big guys".
I just hopefully we see a smaller version. Guess we will have to wait and see.
probably wont, they dropped the sp20 for the big guns long ago, they abandoned the home miners then. |

well what do you know, another item to centralise bitcoins.. all we need is 2 or 3 warehouses in china doing mining, forget the idea of splitting it up over people.. And all this is going to do is increase the difficulty to unreachable heights, rich get richer, poor get poorer.
Its going to take me more then 11,000 years to hash a block, 1 year ago, only 11 years, year before that, about 6 months. you know what will stop this? mega-hashing "companies" go bye bye..
You'd think there is more profit in making little pod miners for the masses then massive rack units that require industrial grade power supply, yes?
and if anyone says "but the U3 didn't sell well" it had a major bug, that never got fixed, no one wanted to buy it.
look at the usb block eruptor, they are still selling! but nooo, lets make industrial grade miners and forget the little people, they can go "cloud" mine off someone.
so, tell me people, what will happen when the 3 major ASIC companies go bust when BTC drops price again?(begging the question, i know) back to CPU/GPU mining for us.
am I the only one to be angry at this? that these ASIC companies listen to the ones with the big racks and cash?
enough of my ranting.

This is the one I ordered yesterday, figured it should run one modified 10 port hub with 5 sticks (with a frankenstein setup) and just a plain hub for the Pi and 2 maybe 3 fans (and should leave headroom on the power). A rough drawing of the frankenstein cross of Y cables, your bridge in the review, TheRealSteve's stick test setup (take a little from each and combine). This way the sticks are in place for an easier cooling setup. https://i.imgur.com/51KOYXi.png frankenstein I bought a bag full of these USB male plug to Female jack to do this hack too, i will photogragh my adventure with this if you wish. (please, don't hesitate to show us your hacks!) |

Well, I'm going to move this onto a electronics forum, see if anyone wants to help out there.
hopefully my "psychological disability" won't be so shunned there.

Sou novo no fórum e comecei a minerar a alguns dias, bom eu li em uns sites sobre hardwares mineradores, mas e muito difícil achar um bom e com um preço acessível no brasil, então tentei ver mais o menos como desenvolver um.
Lendo eu vi que precisa de um Raspberry Pi Ultimate XBMC, alguns Asicminer Bloc Erupter( acho que esse e o nome correto) e outras coisas, minha duvida e sobre o software que vai na memoria da placa, como instala-lo como manusear e quantos desses usb's eu preciso para que a mineração por dia venha cobrir o valor investido em poucos dias.(Não precisam se preocupar com gasto de luz).
Não sei onde conseguiu essas informações, mas você está trabalhando com tecnologia de 2 anos atrás. O prejuízo é certo! Desculpe pelo meu mau tradução , eu acho que ele pode ter lido alguns sites que têm esse tipo de informação velho como local Adafruit Bitcoin |
