@BenTuras. Is it ok to multihome the power cables on a stack as long as they all come from the same psu?
eg in a stack of 5 from a single psu run 12V and gnd to 1,3,5
I ask b/c I've repurposed an xbox 360 psu into a 230W 12V adj bench supply. While I wait on a female pcie connector I planned on hooking the wires up to the screw terminals
In a stack of five, I would connect gnd and 12V from the PSU to the board in the middle(#3) and use the supplied inter board power cables to connect #3 to #2 and #4 and connect #2 to #1 and #4 to #5 The inter board power cable is the cable between the tire wraps and the hex spacers:  (Contents of DIY1 set) |

Are you closer to a firmware update for the Serial connection that works up to your standards yet?
We're still busy optimising it and not satisfied yet. How many boards would need to be setup before you would need to hook up more than one PCIe power cable to them?
The official statement is 5 boards max to one PCIe cable. A good PSU manufacturer will use quality cables and you can go higher. The interboard power cables we supply with the board are of good quality. Also to you suggest two power cables in one board or one on every other one or some sort of scheme?
No, the board works perfect with one of the two PCIe connections used. |

OSM or even a longer name without the number is enough since the communication protocol already reports back the number of chips, otherwise I'd need to manually add any unique combination that comes out every time you design a new board  Agree, so I compiled a version with the string 'OneString' as iProduct. This file is for Con only, please do not update your board until cgminer supports this new iProduct ID!! http://www.btcguru.eu/downloads/BETA/firmware.bin-OneString |

How tall does a 33 stack go?
*grins* I would make 2 towers, but if you insist: ~ 33 x 2.5cm or 33 inch You should rename the special offer to #towerofpower. If you can get it up to 240cm then you can wedge it into the ceiling and no more stability problems You could literally make hot and cold corridors by making towers to the ceiling! Ha ha ha ha ha, your imagination is running wild. OK, specially for you: #towerofpower, 100 bare boards, 22.5BTC - 3 TH/s - the dogie special stock is limited for this special model, LOL |

Replaced by the EASTER SPECIAL OFFER, which runs till Monday. 33 board, ~1TH/s special offer:
This offer is valid till Thursday, April 20, noon CET
You will receive 33 bare boards.
Payment in BTC or bank transfer. 7.5BTC or the equivalent in fiat, exchange rate from bitpay.com.
VAT will have to be added for European orders, unless you have a valid VAT number.
Your order will be shipped by FedEx, free of charge, after we received your payment.
Speed of 25GH/s is guaranteed per board, with proper cooling they run faster than 30GH/s, making a total of over 1TH/s.
Have a look at the DIY1 product for ideas about cooling.
Overvolting possible for even higher speeds, but voids warranty.16 board tower:  |

That would then discriminate against any other cscape based bitfury mining hardware that comes out with >6 chips and alas they all have no unique identifier apart from: iManufacturer 1 c-scape
iProduct 2 bi?fury
Which the bi*fury, hex*fury and these OSMs have as well. Now if you wanted to get the designer to change the iProduct in your devices it would be mighty helpful for both of us. I agree, we had thought about it but valued compatibility with existing cgminer program higher than the additional time required to create our own driver in cgminer. Now that you are supporting our OSMs, it's a different story. (It was our choice to not get you on board earlier). What do you think of naming the product OneStringMiner15, or OSM15 to have a unique iProduct and an indication of the number of chips on it ? The existing customers can chose to update their firmware once there is an advantage in doing so. In the mean time their OneStringMiner just keeps on running with the default Bitfury driver and settings. |

I have received 3 of these bare boards courtesy of BenTuras to aid software development. They are working fine on the current cgminer, though I have added some device specific tweaks which will be in the next release of cgminer due out soon. An example from each board follows: On screen: (BXF was based on Bi*fury and M specifies multiple, hence they're called MXF in cgminer) 5: MXF 3 : 48.2C | 30.74G / 30.68Gh/s WU: 430.0/m
And API stats output: ... Thanks! And I think the abbreviation should be OSM Looking forward to the next version of cgminer. |

I have see that i need to sent my bank details with email but i dont understand what is the next step for purchase the product. Thank you for any answer
Answered by PM, also here: The best thing to do is send in an order and indicate that you want to pay by bank transfer. We'll reply with an invoice and our bank information so you can do the bank transfer. |

We have decided to donate two 3xDIY1 sets to both main developers of bitcoin mining software.
Due to their geographical location, one has already received it, the other will receive it next week.

I cant open the file and from broswer and from desktop.
I get an error too, checking now. Thanks for reporting. Upload of the file is failing over and over again ?! Probably an issue on the web server, will keep on trying and report when succeeded. Tip: Do not use spaces in your filename Although it wasn't the spaces in the name, I removed them. The upload succeeded after 7 retries ?! This is the correct URL: http://www.btcguru.eu/documentation/InstallationManualOneStringMiner.pdf |
