I received the chips from Zefir for batch 3 and up.
I have not received boards from Sebastian's Batch yet.

Once the chips are in hand of my contractor there is not much i can do to accelerate things.
And this week they were down to 1 Machine because of maintenance.
I initially arranged to use 2 contractors simultaneously, to deal with the large number of boards.
The chip refunds cut the board volume to less then half, I had to scale the operation down to reduce costs.  
That also included the shipping contractor.

Regarding bitfury:
I have an exclusive agreement with cryptx until mid October.
Revenue i get on that deal will end up in the refunds.
My 50% refund offer exceeds my current available financial resources.
(all Paypal payments are unavailable)
The refunds are currently suspended because of that.
But I will stand by my word and carry out the 50% as soon as i can.

To any of the "he gets rich" screamers - revenue of this venture so far: about -20.000eur + 4 Months of Work.  
Not that those people will believe any of my words.

I took Sebastians chips to my contractor yesterday was able to get a time-slot on the machine right away. (unlike Zefir Batch 2 where i had to wait)
That time-slot ends later today, with a little luck all boards will be done with smt assembly then.


You could use a thick steel plate as base for the boards in which you screw the standoffs.
Other possibility: lay the stack down sideways.

My test-stack of 16 boards has now an uptime of ~2 Weeks without cgminer restart.
But i am using a rather old version of cgminer.

btw: news in the B'Fury thread: https://bitcointalk.org/index.php?topic=283992

Shipping of Batch 2 is under way, i am too busy to put in tracking numbers (will add them later).

I don't even have time to read the forum anymore.   


Anyway have some PCB Pr0n:

I put the boards back in stock in case anyone wants still needs some.


Batch 2 is completely done and is currently being shipped.
Big orders take a bit longer because i have to put them through customs.
The maximum batch 2 delivery has been delayed by the Bitfury development is 3 days.

Transfers of whole orders are possible.

Thank you for your kind words, i will make some explanatory announcements soon.
Currently i am in a rush to get Batch 2 shipped and your batches manufactured + finish the bitfury development.
But for those who still want/need the old boards, i will put them back in stock.

Interesting alternative in the 28nm league.
I will be watching.


will the package be flip-chip or qfn like dissipating into the board?

i had the chips running at 4ghash in my test setup.
With a proper board more could be possible, more testing is needed.
And like i said the actual costs did increase.

The 470eur was an early estimate, part costs increased as the design continued.
I am not involved in the pricing of the BitBurner Fury units, i kept my margin reasonable as usual.
I will speak to them if costs at their end can be cut.

They are all finished now and i should receive them tomorrow.
To get shorter manufacturing time i need reliable AND exact information when i will receive the chips.
But as german customs were involved this time there was no way to know when i would receive them.
My contractor received the chips on Monday last Week, actual manufacturing began on Thursday that week.

My manufacturing partners offer short reaction times in comparison to the rest of the industry but i can't afford to have the machines rigged up and waiting for the Avalon chips.
The machines have to be rigged up prior to assembly, that takes time and costs money.
Also if i have the machine standing still waiting for a chip delivery that would cost me per hour.



Only if the chips are pin and protocol-compatible it would be possible to use the old boards for them.
(Maybe even remove the old chips and replace them for the delivered ones)
But i think those chips will have a different pinouts/interface/package.

Also with the Cointerras on the horizon i also doubt the Avalon 55nm chips will be available fast enough to compete with them.
Additionally we already have 55nm chips available to us NOW, those are the Bitfurys.

My Roadmap:
end of September to November - Bitfury 55nm
from early January 2014  - CoinTerra - 28nm

Regarding the BitBurner XX -> Bitburner Fury process:
CryptX will provide the chips.
Migrated customers will be able to order before the public.
ETA of the boards: early October.

I have not yet responded to that because i have not decided that yet.
Just to make one thing clear here:
if i do Bitfury boards or am able to sell the components/boards everyone will get those extra 20% (or even more) back.

And the reason for no full refunds is very simple: that money is gone,
or more precisely it is lying around in form of electronic components/boards/heatsinks/fans/mounting brackets/screws/cables.
This is a single purpose venture, no other branches from where money for a full refund could come from.
And it is in your interest to keep it alive so am able to liquidize those assets back into money.
Oh and don't get the false impression the other 50% is my margin, the 50% are just the material costs
on top of that comes labor for assembly.

To clarify how to apply for a refund:
Just send an email stating you want one.
But i need to extra Informations:

Order number(s) > very important, saves me from having to look it up.

In case of paypal thats all.

If you paid via bank wire, i will need the IBAN and BIC to send the refund to.

Now to the most difficult case: Bitcoin
I have bitpay configured to Pay me directly in Euros so i never really received any Bitcoins directly.
To issue a refund through them i need to give them Bitcoins.  
That means i have to buy BTC first to be able to refund the bitpay payments.
For all EU customers a SEPA refund will be faster and easier for me.
If you want BTC, i will refund BTC.
Please note that the current bitpay eur<->btc exchange rate at the time the refund takes place will be applied.
And don't forget to provide me with the BTC address to refund to.

Changing around all the existing orders will be more work then accepting new ones for the people that have chips but no boards.
I still accept orders for the avalon based bitburners for a short while, that statement mainly refers to future board generations.
And It is possible to sell orders that have not been refunded to someone else.

See this post for lastest information: https://bitcointalk.org/index.php?topic=179769.msg3060806#msg3060806

I will need about one week of development time to verify my design.

Lets highlight this passage:
"and cannot be sold without loss to anyone else"
This is exactly the case here because no one would want buy these boards anymore.

precisely

announcement:
I won't be selling to end-users anymore.

Reasons:

• Time. I want to provide you with BitFury and CoinTerra mining boards for which i need lots of development time.
• Development and Manufacturing of electronic devices is my main qualification, not running an online-shop
• I failed to provide adequate customer service.
  Some of you never heard back from their requests.
• The last 3 month i worked 7 days a week all day long.
  This is slowly beginning to take its toll

Consequences:

• I will continue to develop and build mining devices.
• These will be exclusively sold in large quantities to distributors.
• existing orders will be processed and delivered or refunded.
• For the upcoming Bitfury Boards i am negotiating with a 3rd party to manage the end-user sales.
  But i am open to anyone interested that has the infrastructure to handle it.

Further refund information:
I thought long and hard about this whole mess we're all in.
And i am NOT content with the current model.
50% refund is all i can offer >NOW< without going instantly bankrupt.
I plan give back more, if i can.
Therefore any reuse or resale of the remaining components will be refunded. (You bought these with your money after all)
That means you do not need to buy bitfury boards from me in order to get those extra 20% back.
If you can wait until then it could be sent in one transaction.  (about 2-4 weeks to wrap everything up)

I value fairness above most other things like profit for example.
That goes both ways, and almost all of you are upright honorable people which i am deeply grateful for.

To you paypal disputers: i hope you can accept the proposed solution.

Running each board with individual settings is rather complicated at the moment.
Each would need to have a individual USB connection to the host.
To do that you would need to disable hot-plug detection in cgminer.
Then connect one miner launch one cgminer instance connect the next board, launch next cgminer and so forth.
But i am sure Kano can be more specific on how to achieve this.

Yesterday - late afternoon, production will resume on Monday.

Boards like the BitBurners.


More details on the refunds:
Shipping - 100%
VAT - will be calculated and refunded partially
Power supplies - 100%
BitBurner Boards - 50%
Stacking Cables - 50%
 
New thread for BitFury related questions: https://bitcointalk.org/index.php?topic=283992.new#new

Out of necessity a new thread for a new product:
I want to test the waters if you would be interested in such a board

The Bitfury design i am working on is a 16 Chip board with the same form factor as the BitBurner.
I think it makes sense that i will sell boards including the chips now - no more group buys.

Best demonstrated performance per chip is currently 2.7Ghash resulting in 42ghash/s per board.
I am aiming for 5 Ghash per chip, i will be doing things differently then the competition which will hopefully
allow us to squeeze more performance out of this silicon.
Host interface and Controller / stacking will stay the same.

Price: ~470eur+vat (Complete module including chips)
Delivery: early October if Punin delivers on time.

First of all of you should wait and see if the group buys can get a refund from avalon.
If not mining with the board is the better option to get a large portion of the investment back.


Quote §312d BGB

For everyone that seeks trouble:
You ordered a board, you'll get a board.
if you fail to provide Avalon chips it will be missing those, have fun with it.
