Topic: [Group Buy] BFL ASICs, + Board Design Underway. - page 6. (Read 15406 times)
Someone needs to redesign a bigger board with less layers to get the price down.
BFL released just the PCB for the 5Gh jalapeno
Its in Altrium format.
The problem is you can only mount two chips on it (it has pads for 8 I think) otherwise it will get to hot and fry.
They are 10 Layer boards and they are NOT cheap to have manufactured even in 1000 lots they are like $30 a pop
I have already converted the Altrium files to Gerber files, pick files and Bill of materials files.

Yea, BFL also released the gerbers on their forum. I was surprised at the amount of layers. And bypass capacitors.

What is the state now?
I've actually been swamped with work getting the group buy together. Work is slowly progressing on the PCB, though it's been sped up by BFL releasing the documentation of their chips. The plan is to submit the order to BFL on Friday and arrange for samples to be shipped out, and get the design finished and test boards under construction the week following. If revisions need to be made the schedule leaves time for that, and then production boards can be ordered with a longer leadtime to keep costs reasonable while we're waiting for the chips to arrive. Once chips arrive, they'll go to the assembly house for anyone who's interested in having a board made, or shipped directly to you.
Are you planning on producing the board that BFL released gerbers for?
I have 32 codes that I would be willing to put forward to this groupbuy if there is a real chance (as in "100%") that there is a EU-based (preferred: burnin) assembly that provides "ready to run" rigs/boards/blades.
I've contacted burnin(no answer, yet) and I've been also talking with some Finnish PCB design companies. Haven't got any solid offers yet.
If you got any good contacts in Germany we could order the chips straight to Europe and buy MrTeals design and have everything assembled here. One option is to just make clones of the BFL's existing products. The PCB designer who I talked with said that BFL needs to release more info about some component libraries (Altium schdoc) and some firmwares too.

I've already mentioned this over on BFL forums,
but I'm for 96 chips.
My only concern is, these need to be fully operation when I get them (apart from power supplies of course).
I am not interested in receiving these, then having to source my own stuff to complete it (ie. heatsinks etc).
If these can be ready, I plug them into power supplies, and off we go, I am in, and would consider purchasing credits off sellers to increase my already 96 chips.

I have 4 chip codes that I would like to get in with.
If I can find 4 more chip codes available from some one I'd like to get in for 8. That should make a nice little mining rig to play with.

how will the credit program be incorporated into this group buy?
You would transfer the credits to my email address, and the cost for chips would be lowered.Interested. Are there any shipping limitations? Slovenia, EU?
EDIT: not sure if you have this data but how much is necessary to pay at once? Full or half price?

Half price for the chips now, the remainder later. There aren't any shipping restrictions, but I can't speak to what your country will do for duty/tax.
What country are you based in?

So... +1, eh ?
Typo, fixed the spelling and inflection pause for you. 
Is there a thread/list somewhere of the people currently working on BFL 'clone' boards/designs? (KlondikeBFL anyone?)
I believe he's in Canada.
So... +1a ?
I'll be here all week... try the veal!

I'm in for putting my chip codes towards this, and purchasing a couple of devices. I have codes for 32 chips.
i'm in with 16 chips. looking forward for more info./news.cheers
Hey MrTeal, I'm in for atleast 40 chips and have ~168 Chip Codes for sale for anyone interested $7.50 each
EDIT: 8 BFL codes sold to Lucko. Great transaction
