PS: that is why i am still considering mineral oil as an option. It is bit messy but it is just nonesence for me to pay 10+USd for a pice of metal
Remember up to 3 W/chip isnt that much, a passive cooled heatsink something in the range of 1 °C/W is more than enough, and with a fan everthing should be cool as ice. calc: - 10 chips ~ 30 W - ambiance Temp ~ 20°C = 50° C without a fan and it will be lesser with a fan. I will make a FEM simulation with a profile heatsink, and publish the result. |

Where you would probably have trouble is the USB wiring, and I am not sure how many simultaneous BFL devices an instance of cgminer can handle. It would be worth finding out. One USB host itselfs limits number of devices to 127 hubs included  |

Du hast gesucht und ich hab ein Angebot gemacht... Aber naja du kennst ja anscheinend genug Leute die Gutscheine unter dem Wert verkaufen.  Sei es mal dahingestellt aus welchen Quellen die Gutscheine stammen...verbrenn dir nicht die Finger. |

Wenn das problem noch besteht ich würde mich auch drann probieren und helfen.

Suchst du noch, ich kann dir welche schicken, rechne aber 10% Aufschlag auf den Gutscheinwert. Umrechnungskurs von MTgox.
Wenn interesse besteht, meld dich bei mir, gerne auch mit treuhandservice.

Need Help: Can anyone find the specification for the maximum current slew rate on
the USB power signal? I've been looking, but no luck. Specs say min. 100mA - max. 500mA |

Ok I feel dumb but how do you >> you have to be able to sign messages with address used for the payment of the chips!<< ??
Is their some way in the wallet to generate some signed sig, aka like public key.. or how do you go about this.. I did email you but didnt get any reply so I must of did something wrong..
I was in the first batch of chips that where ordered.

Are you planning to develope a real USB connection or only a USB 2 Serial connection?
And what for a microcontroller do you wanna use on the boards?
And do you publish the sources, PCB layouts after you ship your boards or Avalon ships the Asics?
|

A solution which uses a Rasppi would be great.
I wonder how the work is shared, in order that the asics not calculate the same hashes at the same time,
maybe you send the work with a modified nonce to each chip?

This Multilayer s**t, on old PCBs you followed the trace and saw where it is connected but here you cant see shit ^^
Ok we know there are serial DATA in/out, and CLK, maybe Debugs.
I assume the chip hashes <???and compares and if it found something it gives a reply???>.
because it wouldn be possible to stream the data out of the asic and compare them in the fpga.
Ok lets wait for official datasheets and layouts.

Or GPU miners will switch to Litecoin or other Cryptocurrencies.
|
|
|
|
|
I would be pleased if anyone could make detailed pictures of the avalon board with the asics, power stages, etc.
I would like to start developing as soon as possible.

Please read OP. It goes the other way around: you send coins and announce your order here or in PM. Only if required (disputes, mismatches) you have to confirm with your address signing that you sent the coins. That's the most efficient way to handle it, thanks for your understanding.

i would like to make a reservation for 1000 chips, i will send the bitcoins tomorrow in something like 12 hours from now.

When they get a better infrastructure from the mass of money they earn from their ridiculous fees?!  We need more competitors in that market. but its hard to survive e.g: bitcoin-24.com which seemed to be a real competitor. |

SO when buying a computer for mining, what's the most important part? The most important part is to buy NO pc for mining. only as the host for asics or something else but not for mining itself. |

i didnt bought anything still invested in bitcoins, some people say btcs are very volatile but the truth is the fiat currencies are!  |
