[Work in progess] Burnins Avalon Chip to mining board service

[Bogart]

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.

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.

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.

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?

[michaelmclees]

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?

[nomabitva]

@michaelmclees, I think you are correct.

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

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.

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.

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.

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.

^^ OK - thanks, understood!

thanks again for doing awesome work on this!

[Rodyland]

Intriguing.  Good work.

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.

[shibaji]

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.

[alexcamp]

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 ?

I do not think orders are sequential. 200 orders+ is an extreme amount. I really doubt.

Indeed,

$151,320,000 BTC equiv for 2000 orders of 10k chips (the minimum allowed). Seems unlikely.

[hchc]

Anybody know would there be custom fee into US as the finished module would be shipped from Germany? Thanks

[Bogart]

Product name suggestion: Javelin

[cchan]

Awesome！
My understanding for 1 module price:

0.086BTC / chip * 10 = 0.86BTC
          +
tax and custom handling fees (~10%)
effective shipping cost from Switzerland
flat handling fee of $20 per order
(from Zefir's thread)
          +
Expect about 80 Eur assembly cost per module
          +
shipping cost

estimated 2.0-2.5BTC totally

Those who are PMing, what part of the OP do you not understand:

Ordering will be done NGZhang style - via Email.
