It is true, that mounting will be made by Germany company?

Cheers...

Hello

We we will split thing up,

I am handling all sales, assembly, chip mounting and everything for North America.

So if you live in North America your chips will be mounted at my RoHS compliant west coast assembly facility.

if you live else where  in the world your chips may be mounted with me or someplace else. Not sure on that yet - Lucko still has to do the details

But basically how this works is I am reselling for North American customers and Lucko is reselling for Europe and other countries/continents
Our boards are Manufactured in the USA, Lucko may have other plans for the boards he has for his customers but I am not 100% sure on that yet.

So if your a customer outside North America and for questions about where his boards will be assembled you would have to ask him (Lucko)

[Lucko]

I got some BFL chips order from group buy so if I wanna buy board from here and put them together by myself what kind of soldering machine I need? Prefer something easy to use that I can buy from Ebay.

Please do yourself a favor.  Don't do it.  
You'll screw up at least half of them since you have no experience doing it.

Agree if you need to ask for what to buy on eBay don't do it...

Well Form(board designer) is from Germany but I will do the assembly. And it will be done in Slovenia. Also by robot(pick and place machine).

Hello,

I am happy to report that our first batch of Cointamination Production PCB's have arrived!







I will be fedex'ing to form some boards and cooling parts tomorrow to form as well as some sample chips.

btw: we could still use some sample chip donations if anyone has them.

However either way we should know very soon if this production board will work the way we expect it to and will take orders soon after that.

thank you to everyone who has helped to support this project.

If we are in Luckos GB do we need to order from you?
I'm in AZ.

All customers who are in North America can order from http://www.cointamination.com, if you have some sort of discount from Lucko contact him about that and we will work something out. We will have a solid coupon/discount solution for those who have earned discounts in the next day or so.


thank you

Since I will be getting chips from BFL we need to figure out logistics(I will probably mount all those chips)... Main problem is time zone difference so it is hard to talk...

[ryanb]

i purchased 8 chips from a group buy and i will send them for assembly once i receive them


but is it 699 for assembling the chips?

Any other options. $700 is a long way from the estimates.

Don't forget to add at least $800 for the chips, so $1500 for a 64GH/s board.  Works out to $3.5 more per GH/s than bitfury.

It all converges on October, BFL chips, KNC, HF and bitfury.

[Lucko]

I'm sure he is just talking about the page too soon(again)... JJ can you please comment since you setup this page and products...

[JerimiahJohnson]

hi
sorry about the confusion, between my incredibly busy life and the huge time zone difference between myself and lucko, and form we have some mis-communication.

Please dont buy anything from the website until weve tested this board thoroughly.

We will have prices and everything else worked out by the time the board is tested.

thank you for being patient and sorry for confusing you - I was excited to finally get the PCBs in though

Hi
Is there any more information about power requirements?
If these (and other boards) sell well, there could be a problem buying power supplies of the right quality and size.
We may need to pre-order psu's to obtain the best units.

BFL seem to have had problems along these lines.

BFL seem to have had problems along these lines.

These boards use standard 6 pin pci-e connectors, like what you use with a high end gpu

I do not know the exact power requirements per board yet , but it can easily be measured after form assembles the first board using these new rev 1.2 boards.

The datasheet for the chip is here: http://my.root4u.de/BFL_SHA2_Spec_Rev2.2.pdf

Which may be helpful,

But honestly I would just buy a high end certified gold or certified platinum "gaming level" psu
1000w-1200w Seasonic Platinum or Corsair Gold/Platinum Something like that

I actually tested several BFL 50Ghs SC's (they actually do 65Gh/s+) which I believe have 16 chips in them, and I was able to easily run 3 Units from one 1200w Seasonic Platinum PSU. It had enough connectors and plenty of power. So I would imagine the contamination board will use about the same amount of power as the BFL 50 SC here: https://products.butterflylabs.com/homepage/50-gh-s-bitcoin-miner.html

Hope I was able to help.

FYI,

Mini rigs are shipped with two 1500W power supplies.  One running 4 singles (64 chips) pulls 950W from the wall, the other is running 4 singles (64 chips) plus all the sidewall fans, pulls 1100W from the wall.

Thank you for the clarification JJ. Will wait to hear from you.

So my 1000w cougar (with 8 connectors) should be ok with 3 boards but may bottom out with 4?

3 is okay.
4 maybe works, too - but i wouldn't do that 24/7 - unwatched.
Its too near to its limits.

[Bogart]

I'm expecting a 16 chip board will want about 300W.

Its good these units are arriving from October onwards, they will reduce the central heating bill!
