[ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING***

[Dexter770221]

UPS is strange company indeed. Once I've ordered laptop from UK. After two weeks of waiting I contacted them and they say that they delivered but I wasn't home. Well, I was and no single trace (aviso) that they were at my door. Next day package arived and next surprise. I've ordered one laptop and got TWO Who made mistake, dunno till now... But my girlfriend was very happy that she got new laptop

Yup. When they know they've screwed and it's too late already they rush it next day first thing in the morning. Who knows, maybe they send Dave a FedEx girl like the UPS one to make it up :-)

Nope.  Its now in Memphis TN.  BOX #1 Why didn't you get off the plane??!!

Wow. That's FedEx' SuperHub baby: "The SuperHub is a world unto itself, with a hospital, a fire station, a meteorology unit, and a private security force; it has branches of U.S. Customs and Homeland Security, plus anti-terror operations no one will talk about. It has 20 electric power generators as backup to keep it running if the power grid goes down.
Every weekday night at the SuperHub, FedEx lands, unloads (in just half an hour, even for a super-jumbo 777), reloads, and flies out 150 to 200 jets. Its aircraft take off and land every 90 seconds. This all happens between 11 p.m. and 4 a.m. Central Time. "

I'd say if Box#1 doesn't move in the next 2 hours, most likely will have to spend the night at MEM. I'd certainly hand her a blanket and give her some company if I saw it over there.

Are there any components on the non-chip side of the BitFury boards? Any photos available?

I bet there aren't. They'll need the back side completely flat for the heat sink.

You can see some examples in the EU thread:
https://bitcointalk.org/index.php?topic=250249.msg3031271#msg3031271
(although their boards are likely slightly different, but the point is the same - you need it as flat as possible)

Here are some more images:

Most of bottom layer is kept free of components,
except for some passive near the DC/DC converter:

Hi, I'd like to post this here as well

https://bitcointalk.org/index.php?topic=250249.msg3041531#msg3041531

given that a lot of hashing power is going to be delivered soon to this side of the pond.

The circuitry seems so much more simple than BFL's stuff. Which is a good thing, imo. Maybe, I'm missing something.

I have a RaspPi that has been hashing away with a couple bit erupters USB sticks connected for a couple months now.  

Every now and then (once a week or so) I have to boot the Pi because the little green lights on the erupters comes on indicating miner failure.  

Yesterday the Pi died ...  not sure why - it was working away then just flaked out...  now it just lights the red power light - but not the link light, no activity lights, can't ping it -- just died.      

I'm fairly concerned that RasberryPi is not a reliable hardware platform for mining.   I will certainly be purchasing a backup Raspberry Pi to have on hand should the unit Dave ships with my boards goes tits up, too

but am curious whether there is a way to connect the H-board directly to a more reliable host -  running linux or windows or whatever via USB or ribbon cable somehow...

will future revisions of the H boards potentially have native USB connectivity so we won't have to rely on a $40 throw away SoC RaspPi to run our miners?

thoughts?   better yet, Dave, will you offer an option to purchase a backup Pi??

I guess it's fair to say MMHV  (my mileage has varied)...    and up until yesterday I really wasn't concerned and was able to reconnect the erupters to an actual PC fairly easily but that doesn't seem possible with the bitfury setup -

[-Redacted-]

I guess it would not be impossible for someone to create a USB to RPi GPIO/SPI adapter board.  Some of the Bitfury devs are actually having to solve this problem when working on 3rd party boards, and I believe the cgminer team made some comments about this as well...

will future revisions of the H boards potentially have native USB connectivity so we won't have to rely on a $40 throw away SoC RaspPi to run our miners?

Our S-HASH board has a native Ethernet connection and can connect directly to a pool.

See this thread for more info

I have been using 2 raspberry pi's controlling 6 FPGAs (and now ASICs) for the past year and a half with no prob. Just have to make sure you have a very reliable USB hub and power cord for the RPi (don't power the RPi from a powered usb hub, it has issues sometimes)

If there's enough interest, we wouldn't mind drawing up an adapter board for a single H-CARD to USB and/or ethernet.

Well - there's your answer, from the man himself !!  (Not to mention the fact he's already built this...)

Thanks for chiming in cscape!

I, at least, would be interested if it was relatively inexpensive, but I think they are wanting an m-board adapter to eliminate the RPi...
[ I'd be tempted to buy a couple of the h-board adapters and sell off my starter kits ]

Hi cscape, would you consider an M board replacement which provided USB/Ethernet interfaces? Count me in as interested if you do.

[-Redacted-]

Yeah - the problem with doing it at the h-board level is - it would be fine for a couple of cards, but a full rig would need 16 adapters, cables, hubs, getting power to the individual boards, etc.  Not sure it would be economical for running more than just a couple of h-bioards.  But I would buy at least two...

put me down for 2 -->  appreciate the response btw!

[tom99]

  better way to fix Mboard by addon usb and/or network to it.


ps: we need better MOSFET chip for high current like 50A and easy OC it.

You mean a board to interface to the current m-board ? That's basically only a RPi replacement, but less powerful, and at least as expensive.

I was thinking more of a small PCB with an edge connector, where you plug in a single H-CARD. This replaces both the big m-board and the RPi, and would be useful for people only interested in mining with 1 or 2 H-CARD attached to a PC.  For more H-CARDs, the m-board is the more practical solution.
