101  Bitcoin / Hardware / Re: DIY PCB with AVALON - [OP Makeover - Forming List of Developers] on: April 28, 2013, 08:44:39 AM
We can find the values empiracaly from other designs, no problem. What the led R_led G_led are used for anyway?

EDIT:http://www.ti.com/lit/ds/symlink/lm2742.pdf
Look this-->Cc1 = 4.7pF 10%, Cc2 = 1nF 10%, Rc = 229kΩ 1%. These values give a phase margin of 63° and a bandwidth
of 29.3kHz
(from datasheet example)
C2=Cc1 C3=Cc2 R4=Rc

OK, I have a preliminary Schematic for engineering discussion.

https://www.dropbox.com/s/ypqbam0uxwtcav9/BOM_Rough_Draft1.xls

Please take the engineering with a grain of salt. I would love to have some EE's look it over and
offer suggestions for improvement. I'm still having difficulty solving the math to yield values for
the following components:
C2?
C3?
R4?
C6?
c7?
L2?

Any help would be appreciated.

thanks,

KiCAD seems fine to me. But i disagree about the "oven solution". Its not appropriate for IC's because the heat is not diffusing properly at the surface of PCB.
I prefer the clean and more secure method of hot air station with liquid solder paste.

I will put a link of this URL to my web ASIC site now  Wink
Do you have any logo, banner or what?

Updated: check now!



Alright, we need a bigger push to get these chips in.

I want to ask two things:

(1) OP - can you put your personal stake in?  I know you are waiting on partners but everyone will rest easier when your money is up.

(2) Ataxx seems like a nice guy, but he's very new on this forum.  We need to start closing out the remaining 200 BTC of stake.



That said, I propose we work to close out the outstanding 198 BTC through any purchaser available.

I will have an agreement for everyone to vote for or against for a deadline for the escrow tonight, so make sure to sign in later!


Remember, the deadline is to protect your bitcoins so that you can put your money down now with a guarantee that you will get it back should these 200 BTC not materialize at least 24 hours before the ship date for Avalon's large order in Germany.  This is to create options for people who bought in in good faith that this would materialize quickly, and as such the deadline will create safety for those still wishing to contribute.

Sent my original pledge (without my friends)

https://blockchain.info/tx/958472b565b5d19236383dd60bc499eda04351e8212532b4d04d5d8b306a47dd

Please confirm JohnK. P.S I did not include any fees yet. I will do that when  more BTC comes in from MTGOX! Sent raw 17BTC for now!

I hope this will alleviate some stress / pressure / anxiety for some people Smiley


UPDATE!

Alright guys. I think I can move towards the next step in my little business plan as far as working with the local engineers in my state. I decided to purchase domains for my small start up group!

Ladies and Gentlemen, I present to you:



(30 second paint job)

http://neo-asics.com/ will currently point to the updated spreadsheet

I will keep you guys updated on what we plan on doing as far as assembling these machines. After talking to my team we are confident that we can put together a machine using Avalon ASICs chips. But only time can tell until we can put together concrete evidence. We are just doing a lot of research right now but the enthusiasm is really high!

If you are interested in having machines made using your chips send me a PM! This will be a first come first serve basis.

As for pricing we will be asking for parts + labor. Pricing at this point is unknown but you can base it some what on:

https://www.dropbox.com/s/45698vk7bpvbdkp/BOM.xls - from the DIY thread.

Obviously you can opt out anytime you want  this is just so I can see who is interested in something like this!

P.S I need a photoshop guru to design my logo hehe

ASIC's are not FPGA's so it's only for mining and nothing else. Is it possible someone to post a block diagram with the philosoply of the system?

Χαιρετώ όλους! Hi all!
If someone doing mining with cgminer for example, is it possible to show here the screen message that appears when you find a bitcoin?
no secret details of course!

Are there any GPU machines left for mining?
I 'm looking for an ASIC miner like BTF jalapeno or whatever but also looking for DIY machine with avalon asic in a KIT form.
I will trade my domain name http://mineasics.com and http://kbitcoins4u.com for just 10 BTC's for both (or best offer seperately)
PM me if anyone interested about them
TIA
