Final Update (Nov 18 2013):
So, I have finally taken care of the butterfly infestation at my home.
Then it was time to get back to this project and see where it should go.
I spent the weekend building up a few boards with the chips that "daemondazz" had sent (Thank You!).
Everything works except the Nonce capture from the Avalon Chip. The design needs
revised for a better clock filter from the incoming data out of the Avalon. It might as well be revised
for the 55nM chip as well. I believe there is already a good solution found in this open source design
for a clock filter: https://bitcointalk.org/index.php?topic=323175.0
Honestly, I don't have the drive to complete this project only because a single chip miner
seem so pointless given how the mining world has shaped up so far so fast and where it is going.
I would like to dedicate my energies on helping out on some other Open Source projects.
If there is anyone that has the ambition to finish this, PM me. I'll be happy to send
all the Eagle cad Files and materials to help out. This would include x10 55nM Avalon
sample chips and I also have a pickit 3 available if needed. I would also be happy
to share what I've learned and insights that would help get this project to the finish line faster.
Just hoping for the right person that can put the drive back into this and make it happen.
DIY Setup for a little over $200:https://bitcointalk.org/index.php?topic=161715.msg2374824#msg2374824
PCB Version A0 (Build 0). All files found here:https://bitcointalk.org/index.php?topic=161715.msg2426942#msg2426942Low Cost DIY ASIC MinerPurpose:
This thread is intended for the development of a very low cost DIY open source
ASIC miner based on Avalon's chips. Hopefully, it will inspire other Bitcoin ASIC
manufactures to offer their chips as well. Objectives:
* Get ASICs in the hands of the masses ASAP.
* Create the cheapest solution possible. The lowest possible price is the goal.
The $ per hash ratio is not expected to be the best.
* Make it simple enough that anyone with a DIY spirit can assemble one of these with
some simple low priced tools.https://www.sparkfun.com/tutorials/category/2
DIY manufacturing may be an avenue to get these out much faster.
Expect a few hours assembly time per board.
*Make the PCB design that is not only DIY friendly, but mass production friendly as well.
It will use surface mount technology.
*Inspire more ASIC Bitcoin Mining manufactures to pop up all over the world (Decentralization).
ASIC manufacturing in general is the most complicated production process in the world.
IMO, the best thing for Bitcoin would be for ASIC Bitcoin Manufactures to be decoupled from
final product production; or at least offer their chips as well on top of their final products.Specifications (subject to change):
* USB power source is all that is required.
* Utilizes a single Avalon ASIC
* 256+ MH/s
* 2 Watt maximum power usage
* TYPE A USB Male option on either side of the PCB
* Type B USB Female option
* More to comeSponsors:
*Burnin - He is a serious manufacture of Bitcoin mining equipment. He has committed to helping
with the open source software/firmware to make this project function. He has started an official
thread for his miners and it's worth checking out:https://bitcointalk.org/index.php?topic=179769.0
*Zefir - He is preordaining Avalon ASICs in smaller quantities for anyone interested:
Zefir is committed to helping this low cost DIY project be successful by making a small quantity
of chips available for ordering and development.Team:
All of you! An open source design also means its open to anyone. Feel free to take the initiative
to help out in your own way. Please don't get discouraged as it may take time to figure
out where your talents fit in best. I have received an overwhelming quantity of supportive emails
and also many request to help out. I wasn't prepared for that, but now, I would like to make
a list of anyone that wants to get involved here and what they would like to bring to the table.Shoot me ANOTHER email and I will add you name here.
"Someone42" who was the inspiration and pioneer in hardware wallets has offered his help here.
"Burnin" has also offered his help, but is also very busy as he is preparing his own miner.Allten's Commitment:
I will engineer the schematic and the PCB. As soon as the chip specifications are available, I will
release within a week a preliminary design for feedback. I will personally manufacture enough
of these to get them in the hands of all those that will be helping with firmware/software development.
After that, a detailed tutorial will be made on how to order and produce these by yourself.
Important note: I do not want to become a distributor for these for the simple fact I would like
to have time available for other projects I'm passionate about. This is a golden opportunity for anyone
or a few people to become distributors of DIY kits and already assembled miners. I will assist anyone
to get set up for this once I've completed the tutorial.Funding:
Sending some coins would be very helpful and greatly appreciated. 1AqEzSiw7aqZ7T53XvXMqrcnUD5tKcvJxP
What will donations cover? Enough to order the parts and PCBs for the initial boards used for development.
All extra will be used to drive bounties for software/firmware development.
I get the feeling that many have ordered chips with confidence that there will be a PCB solution
readily available before the ASICs arrive. If that is the case, consider donating up to 5% of
what you invested in chips to this project. It would sure help hurry it a long! Much of the bounty portion
may go to "burnin" as his code development for the controller portion will be shared with this project and
he is most heavily invested to make it work along with his product ASAP.
