[Beastlymac]

Beastlymac,

Depending on costs for USB sticks to be manufactured and timing, I'm down for 1000 to 2000 chips.

We won't have usb cost until we have got a design and prototype tested. For that we are waiting on a response from bit main on sample chips that we can use to test the design.

Bitmine still not post BOM and ref design files. Do you have plan to publicize your design ?
Can I count for sample chip to ?

Some of the information was incomplete. Please pm me with your design information.

[Cheshyr]

I assume replies to PMs will go out after the PO is sorted out with bitmain?

[GandalfG]

BitMine update git.
Now we have  schematics, PCBs etc. All  files need for reference design miner and controller.

Beastlymac, time for collect orders and post estimated time for delivery.

[madpoet]

I am happy to order as soon as I can get some rough estimates for cost

Gandalf,
Any link to the github repository containing all the goodies?

It was in the hardware announcement thread in Custom Hardware:

Those are the files we already had. The fab has informed us that the files are missing manufacturer part numbers and information relating to the pin out of the control board. I can get a quote on the hashing board itself along with the assembly cost but we can't get the information for the control board. Also we are missing the compiled pic binary so without all the information we might be forced to either re write it ourself or more likely just switch over and use a raspberry pi.

Or if the released the chip protocol we could design a control board or make a usb adapter that would plug into a host pc.

We also have the option of potentially buying control boards from them but we don't know the price of them yet.

I'm a bit confused I guess.  I loaded up the control board project, and I didn't see any parts that couldn't be derived from footprint and part number, except the generic popcorn parts which you would be replacing with your preferred equivalents in your design anyway... unless you were just planning to reprint their design?

The PIC binary and hashing chip protocol are an issue though, yeah...  I guess could you could sniff out the protocol pretty easily, but it sounds like you're trying to do something a little more turnkey from their original files.  Keep us posted, and let us know when you plan to respond to pms.  Thanks.

Yes we are aiming to replicate the S1 design and would need the control information or the chip protocol to do so. The hope was that we would be able to replicate the design instead of have to redesign parts as that would bring down the lead time and simplify production.

Sorry i missed the pm. Just responded then.

thanks

[Cheshyr]

Thanks for the reply.  It sounds like all the sample chips are locked up in your S1 replication project, so I guess the rest of us should plan on waiting until production chips are available to test out our designs.  Given how bogged down Bitmain is in meeting demand, maybe someone who already had an S1 can sniff out the protocol for you?  That way you can start working on a replacement firmware in case they can't deliver the pic hex.

Talk to you again in a couple months.  Let us know when payments open up.  Thanks.

I've sold some S1 miners to buyers. (5 units)

Buzz me if you still need this info - >> "would need the control information or the chip protocol to do so"

The chip protocol is needed if you want to create your own design. *Buzz* :-)

I'm not certain the protocol information is readily available, or has been provided by Bitmain yet. To sniff it out, we'd need someone willing to attach some electronics to their working product, or at least comfortable with a digital scope.

[Bobs Yerunkle]

I am interested in the S1 Design.

Can order 128 - 256 chips depending on total miner cost.

Just found it,

go go kevin!! im couting on your team to bring us USB units!

[AlexeyK]

if this GB will success i reserve 1000 chips .
maybe more , depending on shipping dates

[ninjaboon]

Put my nickname in for
150 chips ( 1.8 BTC ) // 0.012BTC Per chip

As every chip can hash 2.8GH/s @ 1.1v,
total 420 Giga for 150 chips.

@Beastlymac - any updates for this GB?

Currently no Christmas holidays are causing issues with getting quotes.
