Hello,

I sell the rest of my BFL Chips. You can bring in them to Luckos Clone board:

https://bitcointalk.org/index.php?topic=267649.0

or to the original Mr.Teal Board:

https://bitcointalk.org/index.php?topic=304250.0

The base for the price is the € (EUR).
Payment can be in Bitcoin or via SEPA. I prefer Bitcoin payment with Bidding starts with 5 € per Chip. Bid for min and max amount of chips and a price per chip in €. By using template:

Max. amount in pieces: 
Min. amount in pieces: 
Price per chip:             

The highest price per chip wins the auctions before the amount of chips.
If the lowest price offer will not take Min amount value the next lower offer will win.

Bid also for lower prices if a buyer retreats there bid offer, next lower offer will be win.

You can made a immediate buy if you accept a price of 25 € per chip  

Bidding ends at 30.03.2014 18:00 UTC. Don't forget the change of the day light time next sunday morning. All bids after 18:00 will not accepted!

Transport costs must be paid additionally. I prefer DHL/Deutsche Post Express with insurance.

The parcel will be have a size not more than a big letter (DIN-C4) and not more than 0,5 kg for all chips. You can check it here, who I prefer post sending which looks for like less costs:

Use as sender virtual address for calculation:

Dorfstr. 1
30827 Garbsen
Germany

And now bid bid bid...

Hi,

is it possible to extend my avalon batch 3 by an running Avalon2 card by an 4th module?

Cheers...

Cheers,

I try to make my own pcb :-) Details will follow but here the first facts:

• Main PCB will get µATX, ATX or E-ATX form factor
• Main PSR is default ATX PSR mounted in 19" server rack which the main pcb will be mounted
• BFL Chips will be solder on carrier PCB in one of actual CPU Socket form factor (e.g. LGA1155). They will get an copper heat spread on top mounted.
• Every Carrier can handle one to max 7 chips (maybe 8 depends on needed adress for PSRs)
• On Main PCB CPU sockets will be mounted to connect the BFL carrier and a proper CPU cooler solution
• Every BFL will get there own (maybe programmable) psr (which needs one own SPI address for psr controller) with sense lines as near as possible to the chips
• Option for external clock is planned (maybe need one more SPI address).
• BFL Chip Controller solution is selectable: AVR or Rasberry Pi (or other)
• Temperature will be measure by internal chip temp sensor
• KiCad will be used for planning the layout and design.
• The design files will be shared.

Ready:

• Documentation from BFL stored
• BFL Chips ordered and fully payed
• KiCad installed.
• BFL Chip symbol created for KiCad

Next Steps:

• Generate simple layout for carrier pcb
• Generate simple layout for main pcb
• Create chips to socket netlist
• Select psr module solution

Open questions:

• Documentation from BFL described Done signals in daisy chain mode. On SC Board instead chip done signals are directly connected to AVR. Why?
• What are the possible heat spread sizes for different LGA sockets? In fact also what are the dimensions of different cpu's?
• How much CPU sockets can be used on main pbc?
• Maybe because of large size 2 Layer board could be used for main pcb.
• Is the Rasberry Pi strong enough?
• When will I get my BFL chip order in hand? In 1st week of october as promised?
• How much are the costs of the more expensive parts?

My recent favorites:

• 8 BFL on LPGA-2011 Carrier with copper heat spread because of needed min. die size 42mm x 42 mm
• 8 PowerOne DP8120 POL controlled by DM7308 Power controller
• Rasberry Pi as Controlller with SPI Mode for controlling BFL Chips
• Fallback PSR DeltaOne D12S050201C with trim

To be continued.

Hi,

sometimes the fan of my Jalapeno stops spinning an so the head will go up to more than 65 ° C.
The fan itself looks like not the problem. Possible a problem with the temperature controlling the speed of the fan?

The second problem was the heatsink was not correctly srewed. It looks like the head sink rubber plates between the chips and the heatsink was been disrupted. Because of removing the fan to check them (it isn't really corrupt) I've replaced the rubbers now by heat sink grease. I connected the fan now directly to run with max. speed. The good is, the temperature is now at 42 ° C.

But in fact, I wonder me that I got such an error and I think this is an factory problem. Can anybody confirm that behavior?

Cheers...

Hello,

because of the low price of AVNets Kintex-7 325 Evaluation MMP module (est. 890 $) but the high price of the needed base board (500$) + the to less Vcc distributed current (6A) and high price pdc (300 $) I want to build my own mmp baseboard with minimal functional design.

The mmp comes with soldered memory on board, additional plugs for USB-3 and GigEthernet.
JTAG, PDC lines and io lines are distributed to plugs on the lower side of the pcb. All sense lines are distributed to an different plug.

My idea is to put on one baseboard in the size of an full pci card 4 mmps + power + digilent usb-jtag
connector + uart cp120x chip for simple communication with the fpgas.

I would like to give every mmp there own DC-DC converter for Vcc up to 20 A @ 1V small adjustable with sense support, and all the rest of the needed voltages by one DC-DC converter (I/O, memory, Digilent, UART, ...)
To save my time I would like to use finished moduls e.g. D12F200A or something else.

Hi,

I'm searching the miner stream which I have found one or two weeks ago for Kintex-7 evaluation board.
As I remember the stream has been startet by 400 Mh/s with 1 ring at 400 MHz, 500 MHz should been possible, more rings because of more than doubled no. of LUTs, too.

So I got my Kintex-7 boards yesterday but cannot further find the web page. Does anybody knows where it is gone?

Cheers...

Hallo,

ich habe vorgestern abend ein paar BTC mittels zweier Transfers auf zwei meiner
Adressen gesendet. Leider ist noch nichts angekommen. Den 2. Transfer habe
ich versucht mittels des kleinen Obulus zu beschleunigen.
Wie lange dauert denn derzeit ein Transfer derzeit so? 24 h hatte ich erwartet,
aber 48 Stunden?

Ich habe die Adressen an die ich gesendet habe inzwischen mehrfach
geprüft: Ok. Also versehentlich an eine falsche Adresse gesendet, kann
nicht sein.

MfG...
