B-Eleven sha-256 ASIC miner

[RoadStress]

And with Bitfury and BW stuff all online by then you'll be looking at  > 2EH on the network haha.

From a security point of view it will make me warm and fuzzy.

[wlefever]

2 blades with 2 6pins on each?!

The black and red wires might be from the fans?

Yes agreed on the wires for fans & the black connectors being 6 Pins & the White for data?

Is it that these are an inner casing?



With these pictures being of the complete miner in an outer casing?


Rich

No that's an old pic of Dragon miners

Interesting to see some pictures of the B11 Miner although it does not completely make sense, quite apart from looking nothing like the renderings on their website.

Those wires coming out through a hole look very odd?
Rich

Seems reality of the design process stepped in and objected to the idea shown in the pretty renders
As for the (fan?) wires coming out of what seems to be a hole for LAN socket, rather doubt they were like on the models sent in for Safety Agency approvals. Bare wire through unprotected holes in sheet metal like that is verboten. Only  takes a 1-cent rubber grommet to fix that. Using for a PR pic, um, oops?

Thanks for posting I also find it interesting on pretty different design then rendering.  I do wonder if they make a different one for internal use then external sales.

If I was them I would focus on a miner that is most profitable on sales.  And on internal I would be trying to have more chips, and have most optimized for personal farms.  Having 2 different models might make sense at least at first when filling up their own farms.

Just revisiting these pictures



I think these are probably Miners that have not yet completed the assembly process.

As previously discussed the 4 Black connectors look like 6 pin power, 2 for each of 2 hash boards. The White connector probably Data to each of the Hash Boards. I am doubting that the Black & Red wires are for the fans as you would expect a smaller gauge & 4 wires if you want to monitor & control speed.

However what is missing is the controller Board, can't see that being inside the hot casing? So perhaps it fits on the top of the unit? As to the Black & Red wires I do not know?

Hopefully more pictures & specs will be out soon.

Sweet, should finally see more photos surface soon and an announcement on the bw website.  Wouldn't mind the opportunity to get one of these.

I re-read the article I was to into looking at pictures at first.   I saw in it they say "The power consumption of the BW-LK1401 chip is 160W/T, which makes it the lowest in the industry. Building on this technology the second generation BW-LK1402 chips are currently in production with a lower power consumption of 95 W/T"

Is that a correct number on watts to T?  That seems like a huge and good jump if true.  To think a S7 1300 watts for 4.7T or so, this would do 1300 watt's for 13T if I read this right.... man is that a huge difference in efficiency.

Yes I have just been reading the same stuff and I think we might have been underestimating the B-11.

The spec on the website has 260W/TH which was no great shakes However the article has much better numbers.
   
BW-LK1401    160W/TH which gives 0.16 J/GH significantly better than S7
BW-LK1402    95W/TH which gives 0.095 J/GH getting to Bitfury territory

BW-LK1401 is Full Custom which we had not expected.
BW-LK1402 Optimised design with an ETA of 4 Months.

Found a couple of pictures showing the hash Board.

Shouldn't machines solder the parts together? Or do workers do it individually one resistor/one capacitor at a time.

Looks like the miner will be HUGE!

Most components will be machine placed, some components like connectors can be fitted by hand or could just be touchup?



Pictures are a bit misleading on size, which is actually given in the Miner Photo as 135mm x 150mm x 295mm

Holy shit...they are using a buck for every 4 chips...thats going to be one expensive board. Seems like every chip has a single tantalum output cap as well...thats insane. Looking at least 2-3 bucks of power components PER chip. Then chip cost on top of this...theyll have a hard time competing with bit fury. Does not seem like each chip can output more than 50GH based on the inductor either.

EDIT: Each board has 2 6Pin connectors, so even if they pull 200 watts per connector we are looking at ~400 watts per board, or 2.5TH per board, or ~60 GH per chip which is in line with what I previously calculated based on the power buck design.

[RichBC]

Yes 2 - 2.5TH / Board sounds about right. Much as I like the simplicity and efficiency of String designs it is actually quite nice that this is a Conventional Buck Converter based unit, could make for a more reliable unit with undervolting being easier. Also I suspect that the added component cost is quite small and with Miner pricing not seeming to be based off cost it may have very little influence on the selling price.

Well your look at LEAST 100 bucks in component costs for the buck design in this board. Let say they sell the chip half of what bitfury is so around $5 that will be ~300 bucks, so I can't see them selling this below 400 per 2.5 TH.

well maybe I will get one some day.  but no links for purchase so once again oh well.

A 5 th 400 - 450 watt unit would be nice to own.

Nice Pics RichBC hope to be able to get my hand on one of these

I'm guessing BW get's internal put in first before us little guy's get a chance at buying.   It would make sense as them to want to get as much as they can before having.   And it's hard to say how much of these they will do for internal mining they sold a LOT of cloud so should have a good amount set for this.

The good news is i do think it's a miner we will all be able to own and I agree love the specs as of today.  I just think it will be a while for us to be able to buy one.

[RichBC]

BW have started making payments on Phase 1 of the Hash Investment. Headline sales were a Total of 10PH for B11 & 5PH for B12. However looking at the interest payments and the first B11 Mining income payments I calculate the following.

B11 Phase 1 (Paying Mining Income from 11 Feb) 3.486PH (Paying BTC0.003437/TH/Day)

B11 Phase 2 (Paying Mining Income from 21 Feb) 7.998PH
B12            (Paying Mining Income from 29 Feb) 5.001PH

Total Hash Sold 16.486PH


Rich

EDIT Checked the data & corrected the above numbers. In fact they now add up to more than the headline hash sales...

Thought those 160w/GH and 90w/GH numbers were for the chip, not the miner?

 If so, that puts the miner efficiency at being probably only a little better than the published 260w/GH on the initial B11.

 The 90w/GH figure is nice to see though, gives BitFury some actual competition if/when it shows up.



 Optimally they DID set up the bucks to be controllable for undervolting - AKA the SP20E vs. string in the S5.

Yes good point on the Chips v Miner efficiency. However I think still measurably better than 260W/GH, even if we allow say 10% for the Bucks & another 10% for the PSU that would make it 192W/GH.

Let's hope they have made provision for controlling the Bucks? Hopefully a lot of information should emerge soon on this Miner.

whats gonna be nice if it all falls in line  we will finally have 4 big makers of miners to pick form, prices should come down a lot, we should have our pick of what size we want to buy or can afford etc and still make out good, if it all works out like they claim time will tell.

BW aka LK.


if it all happens and they all keep selling to the public after it happens, i see a very bright and nice time for all .
