I am building my own custom miner clone based on the Avalon2 reference documents with the Avalon A3255 - Q48 chip. Thanks for everyone who have shared the specifications and their experience about the Miner in this thread [https://bitcointalk.org/index.php?topic=210186.0;all] that has proved helpful.

I'll be working on V1.61 as opposed V1.5

I am currently in talks with the Chinese manufacturers to get the boards cloned and preparing all other necessary documents towards making this happen. I'd love you all to join this conversation and share your ideas and expertise to not only build the miner but also increase efficiency and reduce costs.

About myself, i'm an amateur hobbyist committed to learning new sciences, I'm basically a business guy and electronics has been my childhood interest but i had no better opportunity than now to learn and explore it and i am beginning my journey in electronics and thus i appreciate every valuable information shared in this thread. As an entrepreneur i value talent and people who've them and love having experts close in my circle to discuss my ideas and develop new products. I hope the same in this thread and in return as a gift of thankfulness i am giving away three 1 TH/S miners that we build to top 3 active contributors who help me on all technical and engineering other relevant aspects upon the successful completion of the project.

The expected time frame is 30 - 60 days to build the prototype, test and make the functional testing and sample produce it. I may visit china IF REQUIRED and i will choose one knowledgeable expert in this thread to accompany me.  I will post my questions here in this thread

You may also post your questions and suggestions and lets get this going.

Thanks

1 post and free 3th/s miner.

shit, i'm in.                                                                                                                                                                                                                                                             

Hey buddy, its your valuable contribution towards helping us successfully build the miners gonna earn you the free miner.

The Avalon2 Reference Docs. for Backplane that is currently available with me is version V1.5. But i recently saw backplane version V1.61,

Do anybody here have the pcbfile for this version or direct us to its url?

In case any has whereabouts of PCB file download link for the network controller and appropriate firmware for the miner, you may share it here

Good luck!I hope you succeed!

P.S. I like to travel! So I'm in for China!

This any help?     ???

Check your PMs

Thanks Sticky, I've downloaded the contents of this site, but i guess the pcb file for the network controller is missing. Keep us updated if you happen to get it by any chance

Thnks Serje, I'm happy you're in

I noticed that the USB cable from the FPGA controller connects into the Network Controller to which the Ethernet is connected. Do i even need this network controller board ? what does not happen / happens if i directly connect the FPGA usb to PC ?

I know these are pretty basic questions, but your answers will help me go a long way

I've received an update from some of the Chinese manufacturing units that I've approached for cloning that they do not program the firmware. As a matter of addressing this problem,i feel

First, I'd need to know how to install it myself and I appreciate your advise and links/threads on firmware installation tutorials and

Secondly, you can direct me service providers who can perform firmware installation and function testing of our miners. 

Any firmware installation tutorials for Avalon 2nd Generation miners ?

Who has the list of FPGA programmer models that support control unit programming other than Xilinix DLC9LPMC

How about

1) Platform Cable USB XILINX FPGA/CPLD JTAG DLC9G in-circuit Debugger Programmer
2) Xilinx Platform USB Download Cable Jtag Programmer for FPGA CPLD C-Mod XC2C64A
3) Xilinx DLC10 Platform Cable USB-II-G
