There are many projects which are build around the designs from burnin and bkkcoins.
So i think the main developers deserves the sample chips and not the "resellers" of them.

"Best Wurst"
There is something like this in germany called: "Best Wurscht in Town" |

Name it german  Frank´s Wurst! |

Es kann natürlich alles passieren, es kann auch auf NULL gehen, damit muss man rechnen und darf nachher nicht heulen. Ich bin aber Long eingestellt, habe genug Bitcoins, und auch wenn alles weg ist muss ich nicht am Hungertuch nagen. Aber ich will mir später nicht sagen: "Hättest du mal deine Bitcoins behalten/welche gekauft, denn die wären jetzt Millionen wert." So eine Chance bekommt man nur einmal im Leben, das fällt natürlich umso leichter, je günstiger man eingestiegen ist. Naja setzt soviel ein soviel ihr verkraften könnt zu verlieren, und entweder es ist weg oder ihr habt glück und der Gewinn reicht für: - 1 Kasten Bier - neues Auto - Haus - den Rest eures Lebens je nachdem was ihr eingesetzt habt. Das ist keine Kauf/-Verkaufsempfehlung sondern nur meine persönliche bescheidene Meinung. |

Nur zur Info: Ich habe die Datei mal gecheckt, scheint Sauber zu sein, habs in der VM angeschaut und auf Malware gecheckt: http://virusscan.jotti.org/de/scanresult/f7044daed90e58d7c0d6a6861330f5365cf67dc2 Das Angebot, finde ich trotzdem nicht seriös. |

Sorry for that...
better 0.08 BTC than 8.00 BTC hope you have learned your lesson.
Good luck with the rest of your bitcoins!

FPGA boards? Whats your hashrate and which fpgas?  |

Do you need more sample chips? i am going to get 3 pieces and let them send to you from zefir.

Engraved on a tungsten block, dipped in hot wax, using a plastic container that is encased in cement.
Really? Great idea if the sun becomes a supernova the tungston doesnt melt  |

I would like to build it myself, do you make everything opensource, PCB, BOM sourcode etc.?

Make one unified format, so zefir has less work.
I think he can live with the format where the OWNER (burnin) is written at the second position.

if you need one with special holes or something else, i would be honoured to send you one 100mm x 100mm.
Didn't you have long stock 100mm wide? I really like the idea of a long bar heat sink, say 400mm long x 100mm. And then the K16s mount on them in a row so that the heat sink becomes the structural frame holding the boards. For those with tiled arrays of K16 I could see that being a good plan. Then, to go vertical you would put the spacers between heat sinks not boards. I found a local heat sink bar like that - 60cm long but only 30mm wide. It was very cheap, like about $1 or so, but not quite right. I know Avalon says not to mount on the chips, but I'm seriously considering ramsinks w/AS epoxy or TIM pads... they are light, cheap, and transfer heat very well...
You would need to mount those on the back side, not the plastic top. Seriously, the QFN package has a big metal pad on the bottom and the die is connected to the bottom expressly to send heat out the bottom. yes i can get 500mm x 100mm heatsinks as well. Up to 1.000mm length. HeatsinkTell me prefered size and send me the hole patterns and i will manufacture you a sample. |

In order to take the heat from the other side of the pcb is there a special pcb needed for this or is it normal that pcb transport heat good?
The FR4 fibreglass of the board is a poor heat conductor. So what is often done is a grid of vias are punched through in a small area to create metal plated pathways for heat through the board. These are called "thermal vias", and it's what I've done under each ASIC on K16. There is a 5x5 grid (25 vias) under each chip. I'm totalling about 1000 vias on the board now. Thanks for clearing this up... Someone told me that a CE-sign for import into EU is only needed for ready to run-products. In case the boards are assembled but without ASICs the ce probably isnt needed. I mean the receiver hast to add the asics at the end. But i would like if someone with more knowledge could say something about. It has to come without a psu, then there is no need for a CE sign. The rest can be fully assembled. |
