I am under NDA .
So just take my word for it.

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.

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

I think you would need the top heat sink because of the FC package.

The number of chips doesn't make sense I guess... Chip count times chip core voltage should fit the DC voltage of the power supply.

In fact this is not true
You can always use some single DC-DC on the input and arrange it according to chip count

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.

there are at least 3-4 teams(persons) , that have the needed experience and know how as an example:
sidehack , vs3 , me and a few others that did not write here lately I think

I am just curious about what qualifications you have to make an efficient miner? I am not asking to be an ass but out of genuine curiosity. I would go out on a limb and say that your average electronics guy cannot make an efficient miner, let alone the software to run it.

While I can't comment on Mitak, I can speak as a satisfied customer of sidehack. His Compac USB stick works just great. This includes a BM1384 (i.e. Antminer S5 class) part and has a very broad range of power speed options.

I would be willing to bet he could make a dandy USB stick based on their part that would be say 50GH or possibly more. If Bitfury would talk with him, and supply samples at a reasonable price, things would be swell.

Just my unsolicted $.02 on at least one members capabilities.

Sorry, I was asking about Mitak not Sidehack Et al.

If we're looking at wrapping back around to our original TypeZero idea, which would be a quarter S1, probably ten chips to a board for about 4TH/400W stock setting on a four-board kit - which, with a decent heatsink and 80 or 120mm fan could be a standalone 100W pod miner. If I built a stickminer off it I'd want to get at least a 100GH top end capable. That's the main things I'd work on, probably not bother with anything bigger because someone else will probably do it cheaper and mass-produce it for big players. Y'all know Novak and I prefer to build for the people like us.

The design Novak and I are working on should be flexible that we could port it to a different chip without a lot of problem. I'd love to get my hands on some new BF silicon.

How many chips would you put per board?

So since these chips are so efficient and powerful. Why sell them and not just mine themselves instead?

You are right about that, but I don't have $1M so I can't buy chips to build miners and go mining... Even if I want to buy rev3 chips for like $10000 or $50000, no chance how things look right now...

The reason is the MOQ is so high it helps out on r/d costs, costs of their own machines, etc. They sell in such big quanities that they will make a good profit.

So if they have the opportunity to sell a few bulk and make a few million easy quick ROI by selling chips. I predict they will do it, the trick is meeting that MOQ.

If we can get someone to design a board I would participate in a group buy.
