I guess I can share this picture.

This is a board that will be used for testing if we got BFL board right. The only difference is that it has bank of capacitors on top... So we can test how far it will go... New power supply is not ready jet... But it is smart to use unmodified just to test if everything is OK. If there would be a lot of changes and it wouldn't work you might end up wondering did we got BFL part wrong or are the modifications...

Anything new Lucko?

New batch started with order of 9 chips...

OK back from work... Some quality time with daughter and hire I am...

Now boards:
This is not only problem for our GB but every GB out there. Chips will probably needed to be mounted with manual pick and place... Automatic will not be good enough in placing the chips. I know it sounds strange to me too since I would guess other way around. Once mounted can't be removed so any error can destroy the chip on board... So now I'm looking for the best possible company for placing the chips on boards so no problems will pop up... Company I was planing to use isn't that sure they can do it without errors or with minimal numbers of them... But this problem is still 85 days away... It will be solved... They can do the boards and it looks like it will be about 30€ board and 20€ mounting(this is just estimate since I don't have exact number of boards)... Components will add up additional 120€ but this is again estimate since BOM for BFL board is not in documentation and we have not made it jet(I didn't write it down but if I remember correctly 600+ components)... So we are in a 200$ zone. I know this is close to price of Jalapeño but this board has 50% more power. I know that Jalapeño board has 80W for ASIC chips so it should work with at lest 6. What we think is the problem is that small voltage tolerance for chips are making problems so adding more power should help. We also added additional capacitors to stabilize it. What we think is happening is that a lot of transistors in a chip are turned when calculating(something that can happen) on and power usage spikes voltage drops below tolerance and resets the chip. Unfortunately this is the anser I got from BFL when asking if we are correct


So no help from them...

Pictures
I was promised that over this weekend board will be finished so picture will be ready next week.

Next front that I have open is contacting MrTeal to negotiate licencing agreement if this produces a cheaper product for you. He realised this picture

It looks like 5 chips but it is not. It is 4 chips and central one is in case only one is mounted... It might be a better option for those who have only 4 chips ordered or have up to 4 left when my boards are full... or if it end up being cheaper then 50% of our board we will use only those... So as promised best deal for you..

Sample chips

This is a msg I received yesterday...

Batch 2.

https://www.dropbox.com/s/y7eyoyt0nku93wa/cenzurirano2.bmp

104 chips ordered.

Exchange rate 91,7279791. Pitpay page at that time was showing 93,01

I have explained how do they get it earlier. But it looks like they also look at market depth too. And it looks relay good at current exchange rate... 83,42

Next batch is now open...

And thanks for waiting some rest did wonders...

Yeah man, take a week off. You are the hardest working group buy of them all.

Get some rest man. Thanks again for the help and support.

Today I got conformation from BFL that I'm in line for samples... for first order... Yes on a day they should be shipped... Not too good to publicised on GB but I'm letting you know about everything...

I was started to write report but fall a sleep 3 times during that... I will do it tomorrow...

Not realy... This is how they calculate it.
And since BTC-e and Bitstemp are the one they are looking in this case and not mtgox it wasn't that bad... Currently published exchange rate is 90.somthing and in case of a big order it goes down...

Lucko you have bad luck with exchange rate ;-)

Awesome and thanks for the patience while dealing with my PayPal payment.

104 chips orderd... I was doing my best to get good exchange rate by Bitpay but when I sew exchange rate 93 and press order I got 91.somting... I'm getting together with board designer so I will do a full report later on a buy and board...

Founds send to Bitstemp... Should be done today... If anyone would like to get into this batch you still can but it is BTC only

Excellent!  Thanks Lucko.

Done batch full. Moving founds to BTC and then I will order... Probably a day or two... Last payment was SEPA so I should see it tomorrow and then I need to get it to Bitstamp that will hopeful processed it tomorrow.

From now on only BTC payment will be processed in this batch...

It looks like it... I have interest for 16 more chips...

So after that the only way to get into this batch will be BTC only...

Can someone.....anyone...please finish this batch off?

16 chips to the end of the batch...

12 free credits left... After that I have a deal for 112 chip credits for 0.01BTC per credit.

End of batch is approaching... I have 20 more in pipeline if all buy only 4 will be left in this batch...

PCB will be our make based in BFL board... We had some problems with sickness but we are all back to normal.

This company will make and assemble boards http://www.elgoline.si/en/

We get sample chips...

I will be away tomorrow. I'm taking family in spa... So I will probably not answering much to questions...

Hi,

i have twi questions ... maybee i missed the specific answers in the thread

which assembler will work on the PCB? Any commitment?

which assembler will get the sample chips ?
