I took part in team for about 3 different mining boards designs.
A lot of experience with electronic projects etc.
The software is not the problem just a drivers for open source .
Of course the firmware and the pcb is the key work here.
Nice, just curious. Care to elaborate a bit on the boards you have worked on, I am intrigued to say the least. |

The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

How much do you think a board would cost to run 20 chips per board? Subtract the price of the BF chips so I am just talking about the board. 20 chips should run 2TH at .11w/gh so 220W per board. How big would the board need to be? 10" X 10"? Qty 500 boards. I am just curious as to the cost of the board in qty. |

Chip count times chip core voltage should fit the DC voltage of the power supply. |

I don't have a ballpark price on hand but that's not too far from what we're looking to build. A pair of my boards would do 2TH/220W in approximately 6"x9" of PCB and screw onto an S1 heatsink. |

What I am planing ( of course if ever) is 180x120 mm PCB for this kind of chip count with top(just in case) and bottom heat sink . Any price range mentioned would be a big big speculation. Just the bare PCB can be calculated for now and there is probability for change too. For sure I would like to design a single USB stick type miner too |

Yes, so I said top heat sink is in the plan

in the other thread it was April!
tomorrow it will be February!
Engineering chips are going to integrators already in February. So for a skilled and fast integrator I would say late march is possible. April is 100%.  ... And what is the hashrate with heatsink and what's draining the chip??  See for yourself: https://www.youtube.com/watch?v=zZPum2zqGPE |

Decent scam attempt there sir, but it's pretty obviously not the real website.

Looks like preorder has gone live for batch 1 chips. I would love to get my hands on a few for a play around but 2 problems for me, a) I dont do preorders. b) Cant afford the minimum order quantity  What a SCAM attempt. LOL (Admin, please remove it.) Edit: edited  |

Even if it gets removed, the link exists in your quote. Please sterilize.

It says bitfury, etc. You are also saying that someone hacked that "punin" fella account here as well? WTF? Not the Youtube link, a previous post that linked to "Bitfury.com" the link was actually for b1tfury.xxxxxxxx with a display of "Bitfury.com" |

Serious overkill on that heatsink for 11 watts.
Still, not too bad of performance.
I'm not worried about the GH / Chip stuff, Bitfury has always prefered the 'small chip" approach.
It's not far different from the current Bitmain 1385 on GH/chip after factoring the node shrink.
It's also a positive for using a new process node, tends to increase yield some.

Wow over 100 gh/s per 11w, Really want to see these on some little sidehack sticks, 8w 80gh/s would be fine by me.
8-11W/5V=1.6-2.2A, only on the best usb 3.0 hubs, but OK on many usb 3.0 hubs with a good Y-cable. Not sure that the stick usb connector will handle >1.6A, but it is a question to sidehack. |
