Topic: [Work in progess] Burnins Avalon Chip to mining board service - page 181. (Read 624197 times)

I'm excited by all this, but I realized that between the 1st and 2nd order# from Zefir, there is already 200 other orders in between !

That makes 20 million ASIC chips mining Bitcoin in a close future.

Any speculation on difficulty / profitability ?

Great! Thanks. I have ordered 200 chips from 2nd batch from zefir, and will order 20 boards (complete with cooling etc.) from you when ordering is open.

burnin please have in mind 2 powering solutions(if possible): first one for a 1-3 boards and the second one for 10+ boards(stacking). I remember a pic from ngzhang that had 10+ stacks of Lancelot units and a ton of cables and adaptors. I bet people would love powering a stack of boards with one single PSU.

Intriguing.  Good work.

^^ OK - thanks, understood!

thanks again for doing awesome work on this!

But what I'm saying is I'm ordering from Zefir initially.  Then I message him or you or both that that particular order is mine.

Please don't send messages to Zefir he's already flooded with requests.
The way this will work is:
When you order from me you'll have to include a signed message that you want me to receive your chips.
Then i run the checks that you have indeed paid the amount of Chips and that you indeed own the address.
That will be handled by Scripts.
Then i'll forward all the signed messages in a bulk so Zefir can run his own verify scripts on the data.
That will greatly reduce the amount of work and communication.

The rest is correct.



There will be a temperature controlled Fan header.
As for power connectors: adding all kinds of connectors would increase board size disproportionately.

Host software will be cgminer, it will appear like an orignal avalon to it.
But since it will be opensource and the firmware will be upgradeable via USB it is possible to run your own protocol/host-application.

@michaelmclees, I think you are correct.

I'm "on board" for 5 boards(50 chips preorded in batch 2).

I'm trying to understand all this.  So suppose I want 9 modules, which means 90 chips.  This ought to net me about 25GH, yes?

Step 1 is to buy 90 chips from Zefir, by sending 7.74BTC to 162HWpt9njiDsk5nwGixw7fDPuNy55Kh9X and signing the sending address so he knows it's me.

Step 2 is to wait for your final pricing for completed modules, which ought to be about 80 Euros per module, so 720 Euros.  When you nail down a price, I pay you somehow, and wait for you to ship my final product.

Do I have this correct?

Burnin - thanks alot!

please put me down for 20 modules - 200 chips from Zefir - ill ask him to send them to you directly!

question

Who is doing the hardware C/C++ programming?

What software will be compatible ? cgminer / bfgminer?

I'm not sure what the part cost is but it might be cheaper across the runs to support one interface and use adapters for odd-ball combinations. 4-pin Molex would work well combined with some 6-pin PCIe to Molex adapters.

I would like to suggest that in addition to a barrel jack and 6-pin PCI-e Mini-Fit Jr power connector, that the board also have connectors to accept 12V power from a 4-pin Molex, and also from a SATA-style power connector.

Heck, add in some screw terminals too.

Also, an on-board header to power a fan would be a nice touch.  Software-controlled fanspeed would be even nicer.

Well, no, Germany is in the EU (or it could be argued, germany _IS_ the EU)

This leads to a really interesting possibility - depending on the relationship between switerzland and german - but I do not see why it would be different than uk - ukrane for example.

You can import electronics _for assembly and resale_ into the eu (as long as the components come from outside the eu and are the assembled devices are sold within the EU) and no vat is paid anywhere along the line. (although you can claim back 10% as if it were paid - 10% of the 17.5% of uk vat (or is it still 20%?) there is something with the import costs being balanced against the 'export' costs and generally work out in your favour.  If you are charging the value of the cost of the chips for the assembly then you wont pay import.

Caveat: all my experience is import for assembly in the uk.  Law is not a speciality, nor something I pretend to understand - what I have posted has been my experience, and how the process was explained to me at the time. - however I may have the odd detail wrong or backward, this is what i remember being shown.  I will check tomorrow and then update this post if needed.

burinin: We already have our own supply and manufacture supply chain. Is there an option for licensing the board designs, BOM, etc so we can use all our own equipment, just not have to put the work in

I will email when I get a chance.

 

as far as i understand, u plug and start mining

I am a little lost in this world. If you assemble the chips, when I will receive it, what must I do? Plug in on a pc, configure it and nothing more? Or I need to buy and modify some other parts? Greetings.

Dude,

There is nothing guaranteed in life in general and you know it. However burnin seems qualified to do the job to the end. And most important he will make great contribution to the community also, So if you fill that you wanna safe bet go and get GPU it will mine  100%  

Interested but before I spend 35 BTC on chips only, is your service 100% guaranteed to happen or 90%... or less? What happens if Avalon releases info that make your plans change and price rise (or lower)?

Not trying to shoot you down, I am really interested, but being completely incapable myself of doing PCB or building these, I am not willing to spend 35 BTC on chips if something happens making this project not viable and me ending sitting on 400 useless chips.

Sexy. BFL - Burnin's Fantastic Labs.

Exactly, 10 chips per module.


For a single module a 2.5A 12V wallwart will suffice.
Power Stacking will possible through high current screw terminals or 6Pin VGA Bridge cables (not decided yet).
That way 3-4 Modules could be powered through one 6 Pin VGA Connector.
The design will allow the possibility that multiple boards can be mounted on a single heat sink like in the Avalon units.


About 15eur each, still subject to change since board design is not final either.
We're missing pinout and other information that will be released in may.
I will put out a 3d Preview of the PCB next week.

So we need to order 10 chips from your friend that will be forwarded to you, and you make the hardware than ship to us, the customer ?
