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

[quantguy]

This is getting us nowhere. For 10 months we as customers keep posting our very justifiable rage posts and Black Arrow keep deleting posts and withhold our money.

Black Arrow should acknowledge that it's not invincible and we as customers have different tools at our disposal as Hong Kong Police, Hong Kong Consumer Council, Hong Kong Small Courts, HSBC bank and even FBI and different EU and international law enforcement agencies.

So, Black Arrow, come forward and bring fare FIAT and bitcoin compensation proposition on the table.
Otherwise your marketing expenses for conferences like http://insidebitcoins.co.uk/london2014/sponsors/ will be utterly fruitless and even damaging to your brand as well as any future marketing strategies to boost your market perception.

I would be happy to.  Here you go

Please feel free to also post screenshots of your latest order with us.

Geez, David - I know you have a thankless job, even more so now, but how can you continue to work for these con artists in good conscience?

Does someone have to literally die in a fire caused by one of BAs products for you to wise up?

We warned everybody as soon as we heard about the problems and stopped shipping immediately. We told everybody to shut down the units they have, if they chose not to do this is their own risk.

I hope that same filter applies to visitors from 127.0.0.1


David, Alex, Black Arrow - if you've got time to site here deleting hundreds of pages of evidence against you, perhaps you could take the time to answer some of the pressing questions about your conduct, competency and possible liability?

  Fucking gold!

As we're getting no response on whether the bitcoin income has been declared, maybe the agency responsible will have better luck:

Field Audit and Investigation    taxfai@ird.gov.hk
http://www.ird.gov.hk/eng/ese/esi.htm#a08 (on a side note, I'm very happy to see that the IRD of HK know what public keys are, and actually use them! Very good practice IRD!)

I really wish BAS would just answer our questions. I've got more than a few. How about it, Alex, if we nominate a list of questions between all your victims/buyers here, would you give us direct and honest responses and help us plot a path to an acceptable resolution for us all?

That horse is dead no matter how much you flog it.

Actual legal action is the only thing that will have any impact. A real court case. Real papers being served.

We feel like you've effectively stolen our money under a false pretenses and false promises. You cannot be surprised we're all pissed off

As we have announced previously, we are testing the power supplies and waiting for CE certification team to get back to us. Until then, we cannot deliver X3s, no matter how much you flood this thread. Note that we will continue manufacturing X3s and as soon the PSU is ready we'll deliver everything that was manufactured.

We have also started working with a better factory that is able to manufacture everything very fast.

Dear blackarrow,

What about "rent a minion" then?
You stated that electricity is expensive in China and your mining pool was blocked by ISP/big wall firewall.
Hence Black Arrow can't really provide this service.
Will you at least refund these customers?

[FlappySocks]

It is the PSU. The 1500uF green capacitors leak because of unstable PSU. They can be removed by hand as they are not needed. Just pull them out.

I pulled my green caps out over the weekend.  Got it down to 10 minutes per unit, from opening the lid, and screwing it back up.
I'll post details on how to do it on ecointalk when the psu's are available.

What about the X-1 then? If you can't assemble X-3s currently you should have time to clear your backlog of X-1s. According to your own timeline I should have gotten my order 6 weeks ago at latest! 3 weeks ago I've been told by Sylvia my order will be dispatched within "the next few days".
Although the miner is now absolutely worthless because it will cost more to switch it on than it will ever earn it would be nice to even get something for my money I gave you.

Ordered an X1 from Minersource in December. Like most, I have asked for a refund on numerous occasions. Communication from them has been close to nil on this issue.

With notice and out of the blue, today I find a delivery notice pasted on my front door. Attempted delivery of a package from Denver.

I'll accept the package tomorrow since refusing it will leave me with nothing in hand, period.

I'll also record the plugin and bootup just in case the PSU explodes as some X1's have done (very exciting:) but after that I have no clue. I don't want to run it 24/7 making chump change, and feel I might get my 100% seller rating burned if I sell it on eBay.

Maybe I'll put it in the litter box and let my cats take dumps on it, unplugged of course.... We'll see.

Do you have to pay import tax? That would really suck if you receive now useless miners which you paid a lot of money for and still have to pay more. I would have refused the package.

[alfabitcoin]

We wish we would be able to do that but the silicon is not this cheap. The only way we could sell 2th @ $1000 would be to loose money on each miner "sold".

Care to give some more insights in to the cost structure?

For the asic, allow me to make a guestimate based on cointerra's specs.
3 100mm² dies in a package yields 502-720 GH /chip
Lets go with the low estimate gives 166GH per die.

A 300mm wafer yields ~600 10x10mm² candidates or 100TH (at 100% yield).  AFAIK, processed 28nm wafer cost less than  $4000 in volume. Low volume runs may add significantly to that, if you have to go through to an intermediary.
Let be generous and for easy math put it $10,000 per wafer if you include yield, slicing, packaging, handling,.. thats ~$100/TH.

Now thats only silicon cost, excluding NRE and of course there are other costs, like PCB, assembly, housing, cooling, PSU, etc, but I find it hard to understand how over time, you would not be able to sell at (much)  less than $500/TH. Am I way off in my silicon cost estimate?  Or what else is so expensive? PCBs?

So manufacturer price per asic chip is ~10$

[btcminer84]

Just picked it up. There was no import tax / duty. The item was valued at $99.

So, this is scam from minersource to your country government.

How about packaging? And NRE?

Sure, NRE as stated is excluded, but slicing, packaging etc is not. still that can price up only a small amount.
Fact is that chips alone cost less then ~15$ ( with nre) and you had and have huge profit margin. Fur sure you can do a (partial) refund.
And if any third party made mistake then they should conpesate the future cost and not to be paid for mistakes over and over without any responsibility. You do have contracts with them dont you?
You just do not want to do a right thing and refund. Or name the third party involved so we can investigate ourselves.

Edit
And by all means, you would deserve such a huge profit margins if you delivered working miners on time or with slight delay.
Now is evident you are failed and still want to keep all that profit and giving nada in return.
If Iam wrong then please, provide some documents, inovices etc to back up your claims.

No. As several people have pointed out: this is currently a fair import valuation, and it would easily provable as realistic at this value to customs upon inspection. Nothing untoward here.

IMO it shows the real value of the hardware and further proves BA never intended to price match.

[MoreBloodWine]

While BA has it's issues, you can usually rest assured that MS will always check items before shipping them so chances are the X1 you received is fine.

Hey guys,
    Just came across an X-3 for a very good price. Great news.

I read the recall regarding the power supplies on BA's Web site. The previous owner was running the miner on 220 without issues since receiving it.
Is this power supply rated for 110? Does anyone on here have experience running these miners on 110? How much hotter is the PSU when working in that kind of power environment.

It hashes about 800-900, and again...good price...but...thoughts on this miner's performance at 110V?

I just read the recall myself, what I dont get is why are they still listing the PSU's on their website as for sale.

Hope I can get the PSU in my half X3 replaced ok. I havent been able to use it since I got it seeing as how it melts every cord plugged in to it.

I'm mostly afraid that as a second-owner, I won't be able to receive any kind of swap or benefit from BA directly.

On another note, received an X-1 and it wont power up when the hash board is plugged in. Powers up just fine and I can access the controller when the hash board is removed.
I'm using an external power supply and the only two pins I chose to exclude from my harness were the thermistor pins which, I assumed, were for the PSU fans.

Odd behavior, I think the backplane might be borked.

[forzendiablo]

do not plug this, its not working or may make your house burn

[Robin32]

Orderd my x3 in january...items received...0...thank you BA...whole damn scam organisation!

[Specialkey]

Does anybody know if BA has changed their terms and conditions since february?

[Specialkey]

Has anybody took legal action with a lawyer in Hong Kong? Any tipps? Please PM me.

[mahowi]

Got my tracking info today. Order #1700, order date 25.11.2013, payment received by BA 29.11.2013.
