Great to see some work moving forward in the BFL chip area, I just have a random question. Is there a specific reason you went for those huge electrolytic capacitors on the back of the PCB instead of some smaller SMD ones?

Yes there is. if I remember correctly they are recommended to be used with this power module... I will ask...
EDIT: I was right... Recommended part which was declared in the module-datasheet.

Hi Lucko Looking at how far this project has developed in the last month  you could well be producing working miners before BFL has completed its back orders. Does anyone have any novel ideas for racking/mounting, powering and hosting these boards? Some android devices can host, also Raspberry Pi, PC's etc. Racking can be anything from children's building kits, to top of the range professional looking racks and housings. Keith |

If there is interest we have workshop that can do anything... But one-off is not that cheap... We were planing housing but none was interested... But yes we had some ideas but you need enough interest to make it cheap enough...
But if you would like I can get you a quote for your housing... Just tell me what would you like to have...

Looking forward to this board and a nice home for my bfl 8 chips.. Not to mention a bit of overclocking  cheers @form |

Thanks for the update. One question- are these the boards being developed for MrTeal or is he working on a separate design?

Any idea on the price range for mounting loose your own BFL chips/or those you supply would be with full assembly? Would there be volume discounts for 10+ boards? What is your production capacity if you can get these to work correctly?

No this is separate design... His board is using different IC for example Any idea on the price range for mounting loose your own BFL chips/or those you supply would be with full assembly? Would there be volume discounts for 10+ boards? What is your production capacity if you can get these to work correctly?
You will get discounts for 10+ for sure... It is mounting chips no production that is the problem... I'm sure boards will be ready long before chips. So how fast can we put them on boards without errors. This will be tested soon... But I would guess over 100 per day... If necessary we can get additional help. And if we end up with that many orders we need tu upgrade testing area too... You can supply your own chips. You might look into changing shipping address with BFL... I did that when I moved so it is possible... |

Hi Lucko The racking & housing question could almost become a separate topic(there must be lots deep inside the forum) At the moment I am just looking for ideas, possibly designed around the COINADO concept, to make it a unique appearance. Some sketches or photos or mock-ups, of forum members ideas, could start this off. As you say, "one off" is expensive, but something destinctive and cheap could complete the package. |

Hey, dont think that there are so much design possibilities with a Rack case attempt. Of course if its not a rack based design the unique appearance would be possible. If you would go the Rack attempt, i wouldnt make it too complicated and use an existing Rack case and adapt it so a few of those miners will fit it, in my experience this is the cheapest way for a multiple miner Rack case. regards |

Well it was never done with this in mind... You also need to know that 8 board unit uses 100+W and 16 200+W... So cooling elements will not be small... And you need to make it rack compatible... And first test that I made with Jala and see how it is put together I would say I was right about the way chip cool it self... And that complicates things even more... It looks like you will need a heatsink below chips as well... But then again it might be Just the case that Jala had heatsink put on really poorly... That would explain 4% HW errors...
But since this is just a test board production can be made to fit...

Has anyone here with BFL bulk chip orders have an estimate/update on when they should be getting their chips? I know BFL said '100 days' but they also said '2 weeks'. I 'm just wondering if its worth it to get 100 of their chips + these boards, or upgrade my KNC Saturn...

Upgrade the Saturn. If you purchase chips now from BFL the earliest they will come will be mid November (optimistic) and then you will still need to have them installed, etc. |

Yes but I don't think that "2 weeks" was because of chips... Personally I would not put all eggs in one basket but it is your call... And Saturn might end up being "2 weeks"...

There is no way they could get a batch of chips in 2weeks, it takes 2months just to make wafers, then they have to be cut up and packaged into chips by another company. 100days sounds reasonable. |

I think he is talking about the sample chips they said they would ship out in 2 weeks which they shipped out after about 4 weeks.

No he is talking about "2 weeks" BFL is using all the time... Or with other words delays...

You are right about "2 weeks." However, it is true that they said "2 weeks" for delivery of sample chips and were only a little late that time. Also they have a financial incentive to deliver chips since 50% of payment is due on delivery, and the chips will probably come directly from Globalfoundries which should avoid the other supply chain issues. I assume you agree since you are on schedule to have boards ready by September... |

I was just asking to see if is worth it to gamble with BFL again (yeah I know, but bitfurys chips aren't that cheap either). I'm lucky enough I got my Jalepenos somewhat early. If they could deliver 100 chips in 100 days and have them mounted into boards by November it would still have a ROI of 55 days with 40% difficulty raises. It would still consider almost every ASIC company is weeks, months, and in BFL's case a whole year behind on their production schedules, with the exception of the DIY crowd.
Has anyones experiences doing a bulk 100 chip order been better than their regular miner orders? I wouldn't have the tools around, nor the hardware to mount them to test them, but if I do make an order for 100 chips. I could possibly send them to the developers who need them most and hope a DIY BFL solution can actually happen.
