Hi
Don't quote me on this but the price of the board itself fully assembled will be someone around the range of $500.00
We will have a definitive price soon, but this will give you an idea of what to expect.
-JJ
Does that include the chip assembly, or just $500 from the factory to you |

That might put you slightly above the bitfury H-cards. 16 chips +board = $1300 (assuming you get $25/chip credits) for 60 GH/s or ~$22/GH vs $20/GH for H-cards. If you can get them done at $400, that would be exactly the same cost per GH as bitfury. |

Even at 500$ it is still the cheapest option(MrTeal 8 chip cost 300$ estimated without cooling and chris99 240$ but we don't know if it is 6 or 8 chips and without cooling as well)... Board for less chips will cost less. And GB buyers and donors(the one that contacted me) will also get a discount of 5$ per chip. Good enough power regulation (needed by this chips) unfortunately cost a fortune. It is more then 30% of that price. We also need to cover R&D costs. They are close to 10.000$ at the moment. One time boards cost a lot especially if they are rush jobs. Different test parts and components also. Also some additional equipment we needed to buy and so on... And quick laying of the chips on the boards also cost allot... We can't do all that by hand... We are looking to get prices as low as possible. I'm looking for a way all the time. But at the moment it looks like we can't take it down unless you are willing to wait weeks for board to be made...
We are talking about fully made board. And we think that it will do 70GH with good chips and 65GH with below average... But that is just a guess. We have only poor quality chips(below all BFL grades) but we still get on average 3,6GH out. So even that would get as close to 60GH...

Hi Lucko Just been reading some of the early posts, Your very early estimate for a 4 chip board was "under $200" If you compare your estimates with the early BFL estimates, then your figure, of around $500 for a 16 chip board, then you are still on track to beat BFL again. Their estimates always went up and take longer. Your estimates go down and the product arrives quicker. All we need now is 70+ Gh/s from 16 chips and we all win again. BFL must be very unhappy that a private group can produce a better product.  |

BFL must be very unhappy that a private group can produce a better product. Why would they be unhappy? You're vindicating their work by using their chips. Besides, what did your group do? All of the hard work has already been done. Your private group did none of the R&D, they will just take chips and boards and put them together and then ship them. Heck, a trained monkey could do that. |
I do not suffer fools gladly... "Captain! We're surrounded!"
I embrace my inner Kool-Aid.

Can you send me one of thou them... I would love to have one. Your very early estimate for a 4 chip board was "under $200"

I'm still working on supply chain so I didn't give up on the price... It is still estimate... |

OK nice to know but please tell me that that is not what I think it is. Same power supply that BFL used... If so it is only 80A and that is not enough... EDIT: now that I have looked it longer it seems that is not. Right? Now looks like a nice board in a making... |

Our board was designed to support 8 chips without any problem and with the maximum heat dissipation. I am not an expert, as the engineers of the team did this job, but as far as I know supply current for the core of each chip is 10A. BFL power supply is approx 35-40A. that is why supports up to 14GH/s and not much more than that. If BFL's board provided 80A current, it would be enough for 6 good quality chips - 28GH/s. EDIT: If BFL's board provided 80A current, it would be enough for 6-7 good quality chips - 28GH/s. |

How hard is it to solder the chips to the board? Can it be done by end user without any specialized equipment?

I think mounting by yourself is not a good idea. An ordinary soldering iron is to big and to hot. Anything else is to expensive for a diy project, you need lots of work for a laser unit. One damaged chip and your unit is way down on hashing rate. |

I agree more or less. It can be done with hi end hot air system(you need to control temperature well) or if you are really good with soldering station(not really sure if this is the right word in English since it translated words from Slovenian)... So if you are not doing that "every day" I would not recommend that. We even lost one sample doing that testing ways to get them on and off... That is for FrankenJala do it your self videos... I am not an expert, as the engineers of the team did this job, but as far as I know
supply current for the core of each chip is 10A.
BFL power supply is approx 35-40A. that is why supports up to 14GH/s and not much more than that.
If BFL's board provided 80A current, it would be enough for 6 good quality chips - 28GH/s.
EDIT: If BFL's board provided 80A current, it would be enough for 6-7 good quality chips - 28GH/s.
Well it is more like 13A on samples we have but yes... And it looks like you just pointed me in the right direction why FrankeJala is working as it is... Need to look schematic and see if power supply is really 80A or schematic just say it is... BTW you probably messed EDIT I add... So again nice board... I will probably buy one same as goes for MrTeal... As a collection of all boards made for this chip... |

Thank you! Sorry, I mised EDIT. All 3 different designs (yours, Mr Teal and ours) look really good to me, to be honest much better than the very complicated BFL's one... |

Just wanted to update...
According to DHL I will have production PCBs on Monday.
Form could use a couple more samples. (five) more as far as I know so he can hand assemble a production board before we have some made at the assembly facility.
I am willing to donate Free PCB to anyone that gives sample chips to form so he can check the production PCB before we go to professional manufacture
contact Lucko for arrangements.
Also yes I will be offering professional chip mounting as well as assembly services in the US.
Website coming this week.
