I need to back stop and edit a line
John K has returned and paid out coinroll investors and soon the group buy so someone will need to point out a new backstop to fill it in.
Guess change John to a Pirates at 40 reference or something lol.
John K had some serious health issues I guess. Glad to see he is healthy enough to rectify the problems. |

PG hasn't been the same ever since he drank that koolaide.
And took the silver. He has been paid not to post about BFL he is ethically challenged at best and given the xenophobic remarks he really is unstable and can't be trusted to make sound decisions. If only everyone put him on ignore that sort of Global Ignore would be even better than a ban. No one to listen to his hate speech and twisted ethics would ultimately drive him completely over the edge. He needs help with his OCD that is for certain. No wonder him and Josh were able to "agree" to terms. |

Well, I got the Chili working, looking at the CPU under a loupe I could see that there was copper sulfate on the CPU chips which meant it was wet and running for a time period before the power supply blew. Must have been one hell of a storm. Cleaned the chips with isopropyl alcohol and it comes up sometimes when fired. Running now on a BFL single/30 supply, will see if it holds.
Also tried replacing the fuse on the PSU and the house breaker tripped. Wow. Took the Corsair power supply apart and I can see damage on the underside of the power board by the HV switching capacitor. Looks like water pooled under the board where the components were, aided by the plastic insulator, and blew things sky high. I'm guessing the FETs shorted, wow.
The Single is operational but needs the FTDI chip replaced. That's the project for tonight. However since I am one PSU short, running it is going to be a trifle complex. Hm.
Pictures so us visual learners have some perspective of your plight. Nice that you can salvage in this situation. Keep Calm and Carry C3H8O. |

then again this would be laid out automatically with the cad software and I believe that is something requiring some pretty extensive modules in a CAD software something our team doesn't have.
While the power pins area can be autorouted (assuming that's what you meant), I'd just route the signal pins manually first. But yes, try to get more information.. more layers = more expensive, more chances of something going wrong, etc. via-in-pad is a whole 'nother world of hurt that's preferably avoided  My biggest concern is cooling. Any thoughts on this ?
As with the chips you're already used to, vias to a plane on the other side, main cooling element there. You could see if the ground pins can be through-via'd to the other side (rather than to an internal layer, if used). The datasheet doesn't seem to mention power dissipation, so choice of cooling element (anodized at exposed areas) would probably have to come after you've got prototypes complete. Maybe @blackarrow can shed some more light on that, though ( tbh, given the chip has practically only a single purpose and scant few features are optional, I'm surprised to see no 'typical application and layout' section in the datasheet. Would certainly help get their chips to market on products. )Yes exactly... the world of hurt is the issue really and anything that might cause higher fabrication error rates is something you must avoid given the price of a single chip. For us it will require our team to invest in more upgrades to Allegro. We are probably going to look at work to a certain point then have someone with the skills and tools to do that aspect. Be interesting, if you want to sit in our meeting, to bend our EE's ear on this as well TheRealSteve let me know I can PM you the details. Cooling with these are less of problem than with the A1's that is for sure in terms it is not 70% 30% top and bottom. As time goes on these boards will all need some exotic cooling ala Allied Control / Asicminer farm in HK. I am hoping our Hammer Whiteface board will be tested in HK at Allied Control in a new 2 phase system they are designing... potentially from that prototype we could have a Minion Whiteface and "R" Whiteface will be dunked in some Novec but that is something everyone is going to have to move towards if they are going for increased density. Immersion cooling can save you a lot of money. |

I was speculating it is probably something else but he did go on about not being able to get the traces through then again this would be laid out automatically with the cad software and I believe that is something requiring some pretty extensive modules in a CAD software something our team doesn't have.
If I remember correctly he did have concerns in that regard with the A1 traces as the pads on that chip were tiny let me go back and listen again to the meeting recording to tease out more information. The BGA is a different kettle of fish entirely though from the A1 though.
Edit: "You can't run a wire between the balls they'd short" from the meeting recording.

While I have no love for routing BGAs, I'm curious... Did your EE specify why they believe the 'inner' pins can't be brought out directly? It looks like two power planes (row A through AH and the sides of AJ, AK) and signaling pins at row AK that can just be routed straight out one edge, and row AJ that can be routed in between the pads of AK.
Between the pads? Really is there enough space that be a pretty tiny trace wouldn't it? |

This ban will do nothing to curb his enthusiasm for getting it wrong a lot of the time. Getting it right some of the time. Or accepting BTC from BFL on a slow drip and stopped posting about them entirely.
Ethically that is why I "banned" him from my own daily scan of these forums. I think the Mods have done the right thing and clearly explained why. There is little doubt he needs a break from posting and he will be on the wrong side of these rules again in time.

Hello, I am getting quite worried, as BFL hasn't replied or responded back for quite a long time. They aren't letting me know, or updating my status at all. I also sent several replies through the site. And I never got an email from them, and I am expecting an email to say something on the lines of *yes we will need $599 for the trade of two asic miners from 3 BFL units.* As trading is declared on the site. I have over $1900 with them, and quite worried about this. I am expecting updates or something. Its been since June 18, and now its October 16. Its not like I am, bossing around or anything, I am being quite reasonable, and sending once every 3-4 weeks saying through there site any updates? and things. I am just waiting for one email, about an update. But no response since June 18? That's unreasonable  https://bitcointalk.org/index.php?topic=89685.0People already have order numbers, wheres mine? I don't understand. I prepared for this since June, I should be one of the earliest ones. TO: office@butterflylabs.comDate: Wednesday, October 10, 2012 6:04:12 PMHello, this is lightlord, I haven't gotten any confirmation yet but I have said, That I want to delay my 3X832 Units for the ASIC about 5 months ago. Now since its only 3X832, I saw that its 2X832 for one ASIC Miner. Will you need $599, for another ASIC miner? Haven't gotten an email yet. Will I get the 60 giga hash units? Email at goldvictoriacat@yahoo.caThanks David TO: BFLabs < sonny@butterflylabs.com> Date: Monday, June 18, 2012 4:29:35 AM Hello Jody, I have heard about this at http://news.yahoo.com/butterfly-labs-announces-next-generation-asic-lineup-054626776.html -BitForce SC Single: a standalone unit providing roughly 40 GH/s, priced at $1,299 And I have 3 more on the way which two values about the price of above. How long into these get released? Can I be on the first to receive list? Could I trade these 2 of these units for this, so i get this unit first? And on your site you also offer full 100% trade value. Can I trade my Current BFL unit I have, which I have 4 in total. For two of these instead? I will pay the difference and the fee. Best regards David How did this all pan out for you in the end? Be interesting to know what finally happened. |

Advanced Mining Technology: Bitcoin Miner Manufacturer Litigation
Practice: Consumer Protection
Phase: Current
AMT customers seek damages in a lawsuit filed in Federal Court in Philadelphia against AMT for its failure to deliver purchased bitcoin miners and failure to issue refunds causing the customers millions in damages.
Chimicles & Tikellis LLP has initiated a nationwide class action lawsuit on behalf of customers of Advanced Mining Technology, Inc. (a/k/a Advanced Mining Technologies, Inc.)(“AMT”). Named as defendants in the lawsuit are AMT and two of its founders, owners and/or employees, Joshua Zipkin and Jim Brown. The case is captioned: Craig Lenell et al. v. Advanced Mining Technology Inc. (a/k/a Advanced Mining Technologies Inc.) et al., Case No. 2:14-cv-01924 (U.S.D.C. ED. PA).
AMT, which is located in Haverford, PA, holds itself out as a manufacturer of specialized technology equipment used to mine bitcoins, a type of cryptocurreny, or virtual currency. AMT purports to manufacture and sell a line of high-speed bitcoin miners that range in price from approximately $1,500 to $15,000. The “mining” of bitcoins is an increasingly competitive and time-sensitive process by which computer hardware is used to obtain bitcoins by solving complex mathematical algorithms. The Complaint alleges that because these algorithms become progressively more difficult over time.
In their Complaint, Plaintiffs Jared Pela, Craig Lenell and Thomas Urbanek allege they and hundreds of other AMT customers ordered and paid for bitcoin miners which they never received from AMT. After weeks and months of undue delay, Plaintiffs unsuccessfully attempted to cancel their orders and get refunds. As a result, Plaintiffs allege economic damages including, but not limited to, loss of the purchase price and the lost opportunity to mine bitcoins.
According to the Complaint, AMT’s alleged conduct amounted to unfair, deceptive and fraudulent business practices, a breach of contract, a breach of express warranty, common law fraud, negligent misrepresentation, breach of the duty of good faith and fair dealing, unjust enrichment, and violations of various state consumer protection laws. The Complaint alleges that by concealing material facts and making false and misleading statements, AMT was able to wrongfully acquire millions of dollars from customers since mid-2013.
If you are interested in discussing your rights as an AMT customer and/or have information relating to the matter, please contact Chimicles & Tikellis by clicking the “Email us about this Case” form, below. Is there any way to revoke Joshua Zipkin's passport so that he can't leave the country? Last post... awww. What now PG? |

The spam directed at mining fabricator threads who may or may not be evil, so that he could force them into giving him free hardware, seemed a tad much don't you think?

One issue our lead EE has already seen might be the need for a 6 layer board. Paraphrasing our EE at the last meeting: 'The inner pins on the Minion can't be brought out directly to be connected. You will need to use at least 4 layers of interconnect and drill microvias to carry the signals, typically put in the pad, which is a much higher standard of manufacturing that is required compared to the more straightforward QFN chips. It is a pretty risky venture and there are plenty of possible faults that can creep in here. Reworking these could be over $150 per chip and a monstrous undertaking as the chips themselves would require being bumped again or the chip has to be discarded.' Anyone else seen that given the Minion's design?  Minion Datasheet 2014 APR 11 |

Sadly there is NO clear winner in the mining game now for anyone not investing >$1MM  That was always going to be the case really. Group and pool and collectivise your interests and you can keep pace. That is the good thing about Spondoolies they are reaching out and are keen to work with groups and bulk orders. We recently as a group were able to secure some chips so there are still plenty of opportunities available but it won't be like it was in the past an individual at home mining alone. NERD HERDS is your only way to go! Spondoolies is definitely a breath of fresh air in the mining game let us hope it continues. |

Latest Update:
We have paid for our SpondooliesTech Hammer chips which will go into our Hammer Hornets and Hammer Whiteface designs.
We have ordered our Black Arrow Minion chips which will go ino our Minion Hornets.
