Here is a very simple mounting tool that I think would enable any clumsy idiot like myself to do smt mounting.

I hope people support you and get you some chips man.

I definitely want a quarter stick for our school to build.

zefir will most probably send allten 2 chips for his tests. We shared the samples a bit through the developers to optimize it.

Cross-post in all threads of projects that are registered for Avalon sample chips from my order.

Delivery of sample chips seems to have started.

If you have chips ordered with me that you want to support this project with, do it now.

If you are the owner of this project, please provide me your shipping address.

Find the details here.

Hi allten,

I would like to ask for your opinion on BFL offer we got today at https://bitcointalksearch.org/topic/65-nm-chips-bfl-accepted-100-escrow-by-john-k-group-buy-1-kernel32-223571 .

They are willing to sell us (as GroupBuy) advanced 65 nm chips (4 GH/s per piece) on 100% escrow (John K.), on-time-or-deal-is-off policy.

Is developing and producing mining boards capable of running those chips more challenging than for Avalon's 110 nm ones? Would you be interested? (Avalon boards are surely to stay the top priority.)

Since, I'm refining the deal right now, I can use any suggestions about documentation, sample chips etc. I should require for you/other developers as part of the deal.

Thank you.

Dude, please stop spamming the message threads with this question! If you really want to check with the designer of a specific project concerning their interest in designing a board to support BFL chips, a PM is clearly a better choice.

I'm not looking through an Avalon thread because I want to see same tired post advertising your BFL group buy.

does anyone know what is required to program these?

i saw the previews post on what to purchase like hot air soldering iron but it did not state on what is required to program the diy avalon?

It's funny how Yifu is your go-to-source for opinions when he is BFL's direct competitor. It's like asking Mcdonald's CEO what he thinks of the Whopper.

I like Yifu very much, he is a great man and a very capable entrepreneur. But I have to agree with PeZ on this one.

I'm sorry for the OT. Let's keep this thread an Avalon board project. (Until maybe allten says otherwise. Cheesy

)

Project update:

So, I don't follow the threads as closely as I used too. Any Avalon sample chips available out there yet?

The PCB is pretty much finished other than a few more tweaks here and there maybe and some adjustments on the top silk layer. I haven't pulled the trigger yet on a PCB order because I would like feedback if there is any expertise out there. The design definitely wouldn't be where it is today without some of the suggestions and feedback I've received (mostly by email).

Here are all the project files to date:

https://www.dropbox.com/s/nvuxcov9j8eiy2u/TopSilkScreen_Soldermask_June4_2013.pdf

As soon as I get wind of the Avalon chips shipping then i will rush the order on this ASAP. Hopefully, if there are any bugs left, we can catch it before then.

I have two Avalon samples committed to this project. Big thank you to SebastianJu.

I'm still looking for 8 more Sample chip donations that ship before the bulk orders do.
I plan on a initial order of 10 boards. If you have made a bulk chip order, please
consider a few Sample chips donation this way.
Thanks.

Stealing this list for my school.

Hope to get some Nanos / Quarter Sticks for students to work on.

I know this a lot to ask but could you do a few videos on your build? That would be awesome for our students here at school.

never did a video before. i would totally suck!
I'll make one, if you do the video editing. Cut out all the boring crap
make it interesting.

Hehehe... deal... how you going to upload it to me?

I can have kids work on that as well.

We'll figure it out when the time comes.

BTW, if you are setting up a group to build these, there are some things that can be shared.
That will cut down on overall costs. The most important thing where each individual should have there own
is a very nice pair of curved tweezers. Not just any tweezers, but good ones like I put in the DIY Setup thread.

Hopefully one of the group buyers is going to send you a few sample chips.
I wish I had bought extra ASIC's so I could build 1 or 2 of "Quarter Stick"
Thanks for being so open with your design.
