Topic: [BFL-Chip Groupbuy] $27,5/chip 50% - BTC,PayPal,SEPA - 420 sold, 0/100 batch #4 - page 25. (Read 41816 times)

Are you buying chip credits here as well? How much if so.

Just back from another design meeting... Our board designer is really doing grate. We are getting there... As long as we sell enough chips board testing shouldn't be that far off. But we need to sell them to get samples... If everything goes to plan I will be having some computer model pictures tomorrow.

Not problem running 10 of 4 or 6 chip boards having separate USB for 160-240 Gh/s using 10 port hub

Also not problem if chaining boards with standard I2C connector like usually be doing.

Would be happy with ANY board design really working.  One chip, 4 chip, 6 chip, whatever any number chips.  Just wanting in near future, not "maybe shipping September".

Would even buying 12 more chips if putting order over limit.

I was looking all GB are going slow at the moment... I'm the only one who manage to sell any chips yesterday as far as I know... But I have interest for 80, 100 and 5 in a pipeline...

100 is a local order and they would like a meting whit me. Bad news is that my dother is sick so I can at the moment. But I will probably manage that in a next day or two. So if you are planing to order now would probably be a good time...

The picture I see should work with current design. You will lost benefits of connecting them together and use single USB. But I will look into that. It might be done.

This group buy not seeming to go anywhere very fast.

One chip USB plug in with power connector plugging in on side for wall pack power might be interesting - not useful plugging into computer supply if having male USB connector.   Could theoretically running 40 Gh/s from ten port USB hub if similar (maybe bigger) like Block Erupter but heat being major problem.  Would be more happy with smaller boards 4 chips not being USB but being stackable with holes in corners.  

Seeing second picture in this:

This is more of a interest check. If a single chip USB stick would be designed and it would required you to use additional powersupply or plug one cable into a computer powersupply would you be interested in it?

It will be low propriety but it might be ready(if we have no problem with a big board) in the time chips are hire.  It would still probably cost about 2+ BTC at current exchange rate. Might even be more expensive then 1 chip and normal board.

Sorry mistake calculating 32

nice

hopefully bfl will ship the chips ~in time ..

We have 44 chips sold Let's keep them coming

Is maybe not being clear.  This is group by for BFL chips.  Maybe when chips ordered boards being developed and chips can be using for board, but this is buying for chips only now.

12 chips more orderer. Waiting for payment... Slowly but surly...

Hi!

Lead time should be 100 days from me ordering it. But this is BFL so you never know...

When chips are received you have 3 options:
1. get chips only
2. get boards fully assembled with or without chips
3. get hosting(read first post under hosting)

But for 183€ total cost you will probably not get the board and one chip. You need more. I would recommend minimal of 4 chips. For now this is just a estimate:

chips 4*65=260$ (assuming you buy credits for 10$)
board 200$
Power supply 30$

Total 490$
VAT 22% total less then 600$(you are EU)

That is for 16GH+

It is only 60W so it will not heat you more then a llight bulb and it will not be too much noise...

EDIT: If you need credits and don't know how to get them I can get them for you.

Hi Lucko

Relative noob to all this. But I realise its ASIC or go home.....

I'm not sure what i'd be buying into

What is the ETA for actual mining?

Can I buy 3 shares? €183 via sepa (tbc)
(This seems to be the only European purchase where the thread is in English - I appreciate not your 1st language, but still very good.)

Will i just receive a bag full of chips through the post?
That I will then have to get assembled somewhere?

or ->
Can I pay you for assembly?

or ->
Is assembly included?

or ->
Is it hosted and fully assembled (I see the POOL comment, and this would be my preference. Currently GPU mining is driving me mad - Heat and Noise!)
And i receive a weekly payout? (Minus expenses)

In all honesty I need a pay and play solution really
I don't want to buy any more KNC Miner shares as these may not appear in September and I'd like to spread my risk via different vendors technology.

Cheers

Damn, you're right. I did the math a few days ago but I guess I got some numbers wrong... This is difficult with only one USB Port!

We did look into this idea. But you would need more then one port to powering it... Really impractical... Getting 15W+ in pieces of 2,5W is 6 USB ports... And it would still be BIG for USB key... I would be interested if you have any practical idea how to get power from computer... Or active USB hub... I can only see added brick for powering it. Far from simple USB flash drive...

EDIT: It would probably be cheaper and more practical to buy 1 chip and one board. Probably even 2 chips with board. But then again those ASICminer Block Erupter Sticks were also a rip-off.

There could also be 1-chip sticks. This would allow for very small boards (like an USB flash drive). They could use a passive heatsink and 15 Watts should be manageable by using an active USB port.
The ASICminer Block Erupter Sticks are very successful... Although they only got 0.3 GH/s! 4GH/s chips could be quite powerful in comparison.

seems your the only European Group Buy
and your accepting SEPA thats great

Passive heatsinks are probably not possible. You still have 16W12W per chip. One would work 2 probably not unless is BIG and you can forget about more. For 4 you need to take away 64W48W. That is midrange CPU... And that are our cooling planes... Cheap CPU coolers... They are not that noisy. We might add auto speed control at later date to the board but current plans do not include it. But if you have other ideas we will not stop you buying it without heatsink.

About other GB. Yes you will be able to buy just board or send chips to me for mounting but not before our costumers get them. They will have hi priority and other costumers will be low. If GB fails to get at lest 100 chips boards will not be made and all collected money returned. So let get first chips onboard ASAP.

EDIT: Bought too many AVALON's chips so I can't buy more them 8 at the moment.

I believe the other group buys (e.g. https://bitcointalk.org/index.php?topic=236103.60) are also highly interested in your plans! They've already got several 100s batches ordered and are watching this thread.
I, personally, find the fact so interesting that the power consumption of the chips is rather low and that heat dissipation won't seem to be the main problem. So wouldn't it be possible to put the boards for example next to each other and only use passive heatsinks? Or at least a heat-dependent fan that operates very silently. This could be a great opportunity for people who like to keep their mining quiet

We are 95% sure we are right about this two statements:

We can add 2 chips to your Jalapeno if you have a later version of the bord. And do 2gh upgrade. Making your device up to 19 gh(depends on chip but 4 A grade are about there whit OC) I would recommend to take safer option of 16+. Be aware that this voids BFL warranty.

We can also do 7gh upgrade. If you didn't get one chip version or double D grade you can get 7+ out. In most cases we are talking 8+. Be aware that this voids BFL warranty.

There is a big chance of 6 chips to work and small for 8 but you will need to look at cooling. We currently don't have enough data to say if this will work. When we get samples we can confirm.

And because of arm twisting yesterday I will put this out even if it is only 80% there.

We have finished first design of the boards. We are highly confident that 4 chip board will cost less then 200$(taxes not included). The design is not optimal at the moment and we need to optimize the components so we can make it cheaper and we are currently on published low quantity prices for components and 200 boards batch. We are moving in 4 chip modular boards that can be put together. We will live open slots for extra chips(up to 8 ) but stranded will probably came with 4(need to test stability and heat dissipation). You can pay extra 5$ to add a chips or do it your self but then cooling will need to be implemented by you and you will need one power and communication module per board. Hi end CPU or GPU cooler should do it. Also if the board is not stable this is your problem. We will make some test and advise but ultimately risk assessment will be yours.

There are 2 modules. One is communication and power and the chip module itself. You can plug 2 chip modules into a single power and communication module and you can plug also a communication module into a communication module. So you can get a long board for as many chips(there will be some limitations but not worked out jet) you like connected to only 1 USB. We will make also mounting brackets and housings to put them in a KNCminer style configuration. Every 4 chip module will need about 60W. It will be powerd ether by PCI-e, molex or both.

It looks like we will need 6 layers boards for chip module and 2 layers for power and communications. We will be ordering sample boards in about 10 to 15 days but not before we have 100 chips ordered. If the sample chips take too long I will give up my Jalapeno to get 2 for tests.

This is how KNCminer looks like. And this is how our casings will probably end up looking

The boards will be on all 4 sides of a tunnel...
