Re: BFL board project COINTAMINATION - EU+USA facility - ORDERS OPEN
No they can't be chained... I'm waiting for JJ to agree on all prices... But I would guess that it would cost about the same or same as fully assembled with chips since the price in my assembly is the same. It takes just 10 to 20 second less for pick and place machine... So I don't think there will be a difference. But it will be a difference if you will not put chips on right. So I would suggest not to do that. But you can if you would like to do it.
Lucko,
What is the price for the assembly (for the donors like me)? JJ, told me $599 with the "discount". Not sure what that means.
I still would like to assemble 3 boards as I have 48 unsold chips. But I think I'm getting shafted, being chip donor and all.
Thanks,

af_newbie,
we really appreciated your donation and it helped us a lot to get this developed, you should get whatever discount that was offered to you for making a donation. If you were a part of the group buy from Lucko you get what $5 per chip deducted from your price? If no discount was offered PM me and we can work out a deal to reimburse you for your donation.
now onto the board itself, I have some pictures of it with cooling system on, we certainly wont have any problems with heat dissipation! this fan is a monster.
I think it would be wise to have it incorporated into mining software or firmware to control the fan speed, but thats something to take care of down the line.
I'm not hashing yet because I am having a little problems getting the trimpots right and I dont want to blow any chips - each one has to be set to 1 volt (according to form), so I just have them all turned way down right now, I have to buy a better multi-meter today because the one I have is not cutting it, and I want to get these trim pots set exactly right so I dont blow the chips.
anyways heres the pics, I gotta run to radio shack.
ill be around all day playing with this thing. if you need me send email or Pm I will respond shortly.

p.s. after just reading some mail from lucko, I realize now that I did probably kill the first board because I loaded firmware without heatsinks, and thats why I was having problems yesterday, ive got two boards left.
so I think what im going to do is keep testing this board, and send the last untouched but fully assembled board to form along with cooling parts so he can get it working himself, he is much more technically inclined than I am with this type of thing, looks like im going to fedex this morning
that way he can get it working and then give me some better instructions on how to set the thing up, its actually much more complicated than I thought it was, these trimpots have no stopping point so you really dont know when your all the way down or all the way up for that matter, without the correct voltage measuring equipment basically all you can do is turn the damn thing counter clock wise 20-30 times and hope you turned it down all the way
These boards work for sure and the last thing I want to do is destroy another one. form, lucko I am on IRC now we need to talk about this, I really need your help to set these up ,I dont want to destroy another good board for no reason
thank god they are just sample chips on here
