I've got some goodies too! :-)

Thanks Zefir!

Are you going to to an open source board design for it?

I am considering that. But no promises yet.

I have a little bitter taste left from the previous open-source design - which took a lot of work and energy to get it to its current and complete state, and I see a lot of people enjoying the benefits of it, except that I'm still paying the bills. And I still owe to the other people (including Luke) who did such an awesome work to get it to where it currently is.

Sorry, I am not up on that story, what happened to the project, how come it cost you money?

Well, despite our best wishes it turns out that nothing is free in life (well, maybe with the exception of the cheese in the trap). Components aren't free. Boards aren't either. Each sample boards run alone was $400-800 when you add all components and stencils and shipping (yeah, overnight wasn't cheap). Just as a reference - the first usable board was the 7th tested and checked in design. And that's just a portion of the inevitable part that had to be paid with money right away - I'm not even mentioning here the insane amount of work that had to be done in that short time.
So - yeah, it did cost a lot of money, or as a friend of mine put it - I could've gotten a new car for that much money.

Anyways, that's a side story and doesn't belong in this thread. If you want PM me and we can continue there. But in essence - do a search for "nanofury" on the forums and you'll see how many people have used the design, and then look the bitcoin address and see how much donations it received since November.

Shameful that fabricators didn't kick back a set percentage.

[marto74]

some did

some did

Yup! And their logos have for eternity been embedded in the project!

First of all a lot of brain is needed and Unfortunately you lack it. You are not even able to follow tech details in a single thread. But if you find someone to do it for free just share it for free

[papamoi]

Again

It s seemsthere are some idiots here who  think they are still in kindergarden,i advice them to shut up if they have anything to say....

[marto74]

And again , please stay on topic.
And stop calling others "idiots"

[end18]

Today, I got 2 chip.

Thank you, Zefir!

I'll find a way to help Coincraft A1 open source project!

[papamoi]

And again , please stay on topic.

why are u adressing to me and not him?

don t u read his idiotic post/behaviour?

btw are u his dad?because you should learn him how to behave in a forum

as i see you are so prompt to defend him

No he is not. And yes I am an idiot
But I have working board in hand  coincraft 8chips hashing like a beast
Ps
I love you daddy
And you are aware of the fact that my idiotic behavior is on purpose? And you know the reason for it , do you?
I suggest both of us  to stop to spam zefir's thread. Excuse zefir. But every where I catch you here I will comment your childish and stupid posts I promise.
I am not going to comment your posts in this thread any more. Guys here deserve deep respect and you have to be grateful for very second lost for answering your stupid questions
Resume. There is a solid proof that 1-8 chip marto design is working great. Chips can be disabled via cgminer option chip mask 8 bits
And also thre is a solid proof that no matter how hard you sniff here and there you just do not have enough brain to do something valuable. The only thing you do here is to loose our time!

zefir

got the chips today

will need probably more

will pm you

thanks

Hello, could some HW guy give small guidance on the following topics:

- RESETN, CLOCK and CLKMUX are also 1.8V, right?

- When I have multiple chip design, and I have square wave clock generator -> clock buffer/fanout -> A1 chips, do you think there will be problems if I only buffer the clock signal from one buffer to all ICs? I'm worrying about signal integrity when traces get long and noisy

- Anyone had any current readings yet? Should I got with synchronous per IC or asynchronous buck?


Thanks!

Update: Sample Chips available from Bitmine

Folks, please do not be stupid / childish here - be more constructive instead. Samples have been sent out to 20+ parties, would be more interesting to hear of some progress (besides marto's) instead of carrying some fight from other threads into this one.


Sample Chips Availability in Bitmine's Online-Shop
As announced earlier, with the confirmations that chips are working, the time frame for free samples got closed. Sample chips will remain available in low quantities through Bitmine's online-shop here.


DIY Chip Distribution closing
Along with samples, I supplied a dozen projects with 50+ chips for their first test runs. This weekend I will ship the remaining chips to get converted to mining rig. With that, this DIY chip distribution will end. I expect that those who validate their design will anyway order in larger quantities, smaller miners can easily stick together and do a group buy from Bitmine.

I will post the closing date more formal when I know my assembly options, this is just to inform you of the approaching closure.
