I want to do my FPGA development. Where can I get Xilinx developer IDE from?
Directly from the Xilinx website. There's a free web edition which includes FPGAs up to, and including, the Artix7-200, and there's also a 30 day free trial of the full edition. But keep in mind, creating a placed & routed & FAST miner within a mere 30 days would put you somewhere in the vicinity of Stephen Hawking with respect to IQ. I recommend using the free web edition - I think they call it Web pack. |

(100) One Hundred Units - 16 (16.2%) So you might be able to sell 1600 units at least  17 now. Wow - lots of millionaires reading bitcointalk.org... |

I paid slightly less than 30K for my [upgrade] order of two BFL SC miniRigs, with an aggregate hash rate of 3 TH/s - so why would I want to pay 30K for a measly 400 GH/s?
An absurd proposition.
Yes, you are right, if BFL continues to sell their now 1 TH/s rigs at $30,000, so if that is the case would you buy at $15,000? Just trying to see what the interest is here. I'm not going to buy at a HIGHER price per TH/s than I already have. I paid $10000 per TH/s. Thus, I'd be interested in ASIC miners at or below, say, $8000 per TH/s, especially if they draw significantly less power than the BFL ones. |

I think Artix-7 would be the best one/most cost efficient to mine BTC on, Virtex is a bit of overkill, and a lot more expensive.
Zynq would probably be amazing as well though (I think)
It seems to be a lot harder to get bitcoin miners to place and route successfully on Artix-7 than on Kintex-7. Do you know, is that just because the Artix devices are smaller, or have Xilinx 'cost-optimised' the routing resources in Artix? The usable chip area of the Artix-7-200T looks like a giant 'H', think of a building signage 'H' as in 'HOSPITAL', with two unusable 'parks' thrown in for good measure, a 'Central Park' and a 'Golden Gate Park'. As far as I have been told, the usable chip area of the Kintex-7 is a huge rectangle. Get it? |

So we could wait for someone who ordered a mini rig. He will probably be pissed enough to be still pissed, even if the device arrives  I would not doubt it. I am wondering how gigavps ended up with a Jalapeno considering I don't think he ever ordered one. It must be a placeholder for the 4 mini-rigs that may never come. Think about it. Let us say the Single works... and they deliver 30 singles :D:D:D:D I know of a mining service that ordered three mini rigs. Now thinking about setting up 90 Singles, that sounds like a pain in the ass For the record, I ordered 2 minirigs and would have no problem receiving 50 of the 60 GH/s singles or 60 of the 50 GH/s singles in lieu of them. Quite to the contrary, this would make it easier for me to plug the devices into different power lines and strategically put them underneath separate A/C vents. |

Wow, after Dabs you are now the second RP-based guy.
But Dabs has not received a single order yet.
Does Cebu City suffer from rolling blackouts?
If not, how many power outages per month, on the average, and how long do they typically last, on the average?
Just curious.
Will your Avalon condo have a backup generator?

If there aren't push/pull fan configuration in that new case - .....
I'm just going to hope BFL did the obvious. BFL is good at dashing hopes, though.
It's push-pull all right. |

I guess that would make it an 8 GH/s Jalapeño plugged into a surge protector that's plugged into the wall.
I guess they disable 12 of 16 mining units on the second chip, or something like that. Anyway, just quoting what Josh says. |

Getting back into topic, this is the BFL reply I got a couple days ago.. ---------- Forwarded message ---------- From: Butterfly Labs Inc < office@butterflylabs.com> Date: Tue, Apr 23, 2013 at 5:09 PM Subject: Re: New mail from contact form To: Felipe All of our current models are available for preorder on the website. We are shipping 4.5 gh/s ASICs to developers early preorder customers. Prepayment is the only method by which your preorder is entered into the queue. We are working to start shipping in the next couple weeks and have a backlog in the queue, so new pre-orders, regardless of product or power consumption, will likely ship sometime in late August or early September, sooner if possible. They probably need to update that message, they no longer have a 4.5GHs model. Or ffernandex fabricated this email… Josh said in the so-called shout box on the BFL website, that each chip can only get to 4 GH/s on air cooling and that they have to put 2 chips into the 5 GH/s Jalapeño. |

New single case  A bit hard to tell how bit it is without something next to it as a reference. It's about twice the size of the original single, and it has two fans inside, at opposite ends. |

Nice to see them screw over Single and minirig customers.
Exactly my sentiment. If you are a premium customer, i.e. sent them a wire transfer for 29.5 grand or whatever 5-figure or 6-figure amount, you would expect to get premium treatment and don't deserve to be kicked to the end of the line. It doesn't matter to me in which shape or form they ship me my minirigs, whether each comes in the form of one case with five 1600W power supplies and really strong fans or five cases with a 1600W power supply each, or even in the form of thirty 50 GH/s singles - minirig customers do not deserve to play second fiddle to the "here's your Christmas present from dad" Jalapeno riff-raff.It would be completely un-American, communist even, to ship all the Jalapenos to the riff-raff first and leave the premium, high-value customers waiting and fuming. Just my 2 cents. |

have you ordered the chips or are you waiting for people to fund this project?
Regards
We are waiting for investors to fund this project and as soon as we hit 780 BTC we will order 10k of Avalon ASIC chips. Good luck with that. It's so massively overpriced, it's not even funny. Let's assume someone wanted to buy boards with a total of 10000 ASICs on them. 3500 BTC is, whatever, $425000 for 2800 GH/s? Seriously, man? |

I find it amusing as well as sorry for the poor Avalon Batch #2 customers who paid 5 times less for ASIC machines that can do 6 times the hash rate of ASICMINER Erupter Blades. Hmm.. I wonder who will be better off 2 months from now? I find it rather amusing that asicminer customers will have their erupter blades sooner than Avalon batch #2 customers will have their Avalons, which have been ordered in february This. |

do you know how you were compromised? putting the same code back up might just let the hacker back in...
yes we do...would be silly eh? So - pray tell! |

Do yourself and us a favor and take the preorder out of it. It doesn't fly anymore. Front the cash yourself to finish it up and you will have customers lined up to get at 'real stock' when you are ready.
[/end thread]
This. Preorders have become a question of whether customers take the risk now or the business does. Given the amount of fly-by-night operators and ASIC start ups - along with the BFL fiasco - I don't think you'll find many willing to accept the risk as a customer any more. Seconded. |

What's the wattage of one chip at nominal speed?
I would say that if Avalon ASICs machine uses about 600W @ 65gh/sec that would equates to about 230 chips @ 600W so about 2.6W a chip? Just a rough calculation lol please don't quote me on it! So, if someone bought a 10000 chip lot and decided to keep all of them for himself, he'd need about 30KW to run them, power supply efficiency included? Wow. |
