Black Arrow 28nm 100Ghash Bitcoin ASIC from $0.49/GH/s

[ChuckBuck]

You're right, ignoring the fact that SP is actually offering preorders and promises and the fact that their in stock hw is way overpriced. Even bitmain is overpriced now that they stopped lowering the price.

What do you consider overpriced (in terms of $/GH)?

Anything more than this:

http://shop.rockminer.com/goods.php?id=35

Are they shipping now?  Did I understand correctly, 2BTC for 1.2TH? (So basically around $1/gh) ?

Shipping starts June 25.

So these don't come with power supplies and are 2 600 GH/s boxes for 720 Watts or 1440 Watts altogether.

Really like 2.2 or 2.3 BTC or more with single PSU's or 2 PSU's.  Asicminer really blew chunks this generation efficiency wise.

Over on ecointalk someone posted a snippet of an email from Minersource saying that units are inbound to them and they have tracking numbers. Could it be true?

Since that would be good news, why wouldn't they spend the 5 minutes to post it officially?

That's true. I'll only add that David did say, as quoted here, that there would be an update late tonight early tomorrow.

Perhaps they're working out the details of new compensation. Perhaps they're all busy boxing miners. I don't know their reasoning and don't want to speculate beyond that. We'll see.

[abdullahadam]

You know what's even more overpriced? Loser companies that don't ship.

haha.. +1

Agreed.  Even $0.01/GH is overpriced when it doesnt ship

It better be one hell of an update.

Why would BA ship to resellers first when they haven't even started shipping to its direct customers yet?

Order via BA #207 Still nothing Shipped.

I emailed them yesterday (no response yet) with the follow question/statement..


================
Hi there..
Last week on http://www.blackarrowsoftware.com/store/bitcoin-miners-progress-update--29-may-2014.html it was said:

"
Mass production in under way and shipping will start from the beginning of next week."

and before on:

http://www.blackarrowsoftware.com/store/bitcoin-miners-progress-update-22-may-2014.html

You said "To avoid any further delay we have the option to deliver the case-less X1 if any of the customers will choose so."

But its the end of the Week now and I have seen no evidence of my Unit being shipped yet.

Do you have more delays and if so can you give and indication on when it will be shipped and I have a tracking number of the unit I ordered 9 Months ago and has been delayed around 5 months due to issues you are having with the X1. Are you still having issues with the X1?

Why would BA ship to resellers first when they haven't even started shipping to its direct customers yet?

Because resellers are probably their biggest customers.

[Slander]

My 20 X-1's have been happily hashing away for weeks now, ok, wait, that was a dream, but Im still waiting



Hey, I held out for my coincraft desks and they are working really well, build quality and stability is amazing, boots fast and the admin screen with the speedometer and overclocking controls is just fun. Would love about 20 more of these bad boys.

Here is a pic of one, had to take the side panel off for cooling as they run hot when you are making them work. Watermark added to pic to prevent scammers from trying to sell stuff they dont have buy using other peoples pics. May such people sit by and watch all their family members get cancer and die slow, painful deaths. (which will happen because thats karma baby)

[AchrafB]

It's 1:15pm in China. No update. No excuses anymore..

we'll all go crazy :/ and you goozman96 I feel that you're going to freak out 

[btcminer84]

Please be patient. the next "next week" excuses will be done "any day". 

[LennonNZ]

Please be patient. the next "next week" excuses will be done "any day". 

I got an email back from BA. I can't post it due to them posting a "Privacy Disclaimer" they have just added back to their emails which says people can't discuss any replies back from them.

Bitcoin Miners progress update – 06 June 2014

Minion ASIC
All ASIC chips orders have been dispatched.

Software
We have quickly ported our software to Raspberry Pi which is now included in the SD Cards delivered with Raspberry Pi solution (preloaded). [Pictures attached]

Prospero X1
Control Board / Raspberry Pi
The shipping of Prospero X1 (Raspberry Pi version) is ongoing.
We are using Raspberry Pi instead of our custom designed control board because we have identified an issue with cgminer not working properly with our control board. We have not yet found still where the issue occurs (hardware or software).
The initial feedback from the customers using this solution confirmed our endurance test results. The miners are hashing steadily at 1.2Ghz. Average speed is 118Ghash and peaks at 131Ghash.
Please note that we will continue to ship the Raspberry Pi solution until we will complete fixing the control board issue.
The X1 Prospero (RPi) miners will be packed with 8 GB SD cards which will contain the latest software package.

LCD / Touch Screen / Buttons
The X1 Prospero (RPi) will not contain LCD, Touch Screen and Buttons because RPi does not support these features.
The X1 Prospero (with control board based as per original design) will contain the LCD, Touch Screen and Buttons solution but will be shipped at a later date.
Customers who prefer waiting for the LCD & Touchscreen are asked to contact us immediately so we can postpone their shipment until LCD is available.

WiFi
The cases for X1 Prospero (all versions) will continue to be manufactured from metal which will interfere and disrupt the WiFi signal therefore we decided to suspend it. Any customer has the option to request for the WiFi solution to be included. We will be happy to include this solution on request when it will be available.

Power supplies
In order to optimize the shipping time we have started shipping power supplies in advance.

Prospero X3
Control Board / Raspberry Pi
We decided to try to use 10 x Raspberry Pi per X3 as a quick fix to be used temporarily. Initial results are encouraging (hashing performed). The test board will arrive tomorrow. If this quick fix will prove satisfactory, we will consider shipping X3 Prospero (RPi) solution on temporary basis until the control board will perform as per original design.

X3 Backplane, X3 Hashboard PCB
1.The only problem that we have with X3 can be explained very simple: any hashboard (2 ASICs) will work (240Ghash) in any socket of the backplane but they will not work if we plug more than 2 hashboards in into the same backplane.
Investigations took us 2 weeks working 16-18 hours/day as we went through everything from debugging the power supply to debugging the cgminer code and reviewing the ASIC code.
We now strongly believe that the problem is due to noise on the 3.3V line which is currently shared between all hashboards. Unfortunately the 3.3V line is inside the backplane (layer 2) and inside the hashboard (layer 3) and we cannot separate them in order to get the current backplane working.
We have now almost finished a new design of the backplane which includes all the technical solutions solving the SPI noise and we aim to send it to PCB Factory on Monday. We already have the hashboards manufactured and if the new backplane works as expected we will be able to ship very soon.
2.One of our partners, which is specialised in ASIC manufacturing, has completed brand new versions of X3 Backplane and X3 Hashboard. They are currently running simulations and will send the PCB to manufacturing on Monday.
3.Three other companies have started to redesign other boards for us but their progress is not as advanced as our own. We will be taping out their design when ready and if it performs better we will use it in the next versions.

Notes
We received queries and suggestions regarding compensation packages. We will address the compensation issues as soon as we resume the shipping of the full spec Prospero X1 and Prospero X3 miners. We recognise the importance of this topic and our management team will address it accordingly.
Few months ago we announced that we have a surprise in store for our customers. We will disclose the full details as soon as we resume the shipping of the full spec Prospero X1 and Prospero X3 miners.
There are no Prospero miners X1 or X3 which are hashing on any of our facilities.

  issue with cgminer not working properly with our control board 

Don't know why I suspected something similar about 2/3 weeks ago, when I first hear - Rpi solution.  For X1 the bad escalation has been.......all Ok, next week - LCD missed, but next week - LCD & case missed, next week obviously - now LCD - case and problems in control board.

To all people that are ordering tons of PSU, I really admire you. I'm asking myself, what if after that long wait we suddenly discover that psu is a bottleneck to overclock

[ashleysly]

$6999 for 2TH/s? I think thats rather cheap. I wonder if these products actually exist or is it some sort of scam to get thousands of $$

Anyone received anything yet?

Prospero X3
Control Board / Raspberry Pi
We decided to try to use 10 x Raspberry Pi per X3 as a quick fix to be used temporarily. Initial results are encouraging (hashing performed). The test board will arrive tomorrow. If this quick fix will prove satisfactory, we will consider shipping X3 Prospero (RPi) solution on temporary basis until the control board will perform as per original design.

Hey BlackArrow, remember when you said you were looking for help from the community in solving the problem and you would offer rewards.

Black Arrow:

You asked for technical solutions. I might have a very simple one.

DITCH THE BACKPLANE
 JUST USE WIRES

Or, if you can't do that, put in a controller for every hashboard. You'd lose some money and a tiny bit of power would be wasted but it's time to ship.

Though of course you scoffed at the idea when I posted it. Glad to hear it's working for you. PM me and I'll let you know where to ship my huge reward.  


Also seriously?

WiFi
The cases for X1 Prospero (all versions) will continue to be manufactured from metal which will interfere and disrupt the WiFi signal therefore we decided to suspend it. Any customer has the option to request for the WiFi solution to be included. We will be happy to include this solution on request when it will be available.

You need to put the antenna outside the case. Try this.

[LennonNZ]

fucking shit update - we seem to be behind than we were last week - Jow many have you shipped BA? 1, 2 ?

As far as I can tell no one on here has had confirmation of shipping and/or has one in their hands. I am order #207 from BA. Does anyone have any order numbers below this and can verify they haven't got one yet.

I would be great to know if anyone independently from BA who can say they have an X1

[Vcore]

If the problem is noise in the 3.3V line it is easy to test it.

Cut the 3.3V traces going to the pcie conectors in a backplane or if it cant be done due to the layout/multilayer pcb just remove the 3.3V pads in the hashboard and then feed it with clean 3.3V, if you want really clean 3.3V use a 3.3V linear regulator feed with at least 5V and with big filter capacitors at the input and output.

Not the most efficient and likelly not an aceptable solution but the power will be as clean as it can be and you will know for sure if it is worth trying to make a pcb that has lower noise on the 3.3V line or not.

That can be cobled together in less than an hour if you already have the linear regulators. I like this one: http://www.ti.com.cn/cn/lit/ds/symlink/lm1085.pdf .

Although perhaps that is exactly how you came to the idea that the problem is in the 3.3V line.

[ernie-]

I am having trouble understanding the last update, exactly what is being shipped and when for people that have X1 orders via Minersource?
