I started a dialog with parts@ and got a reply from
tim@hashfast.com regarding getting the manufacturing files, firmware and sales process. +1 to know their historical yield on boards as this is a non-starter if the yield is low.
He states:
"Once you purchase Golden Nonce ASICs, you will be provided the manufacturing files (schematic, BOM, and PCB layout files/Gerbers) for the mining board. The tools and software is already available at
https://github.com/hashfast .
Please provide me your address, and phone number and I will get an order confirmation sent to you for the Golden Nonce ASICs along with enough of the 5 hard to find parts to build boards. Once we have received payment, I will send you the manufacturing files."
Completely useless until when they release the design of their board under public domain. Firmware included. And I wanted to see both the evo and the new half costs version.
Even after that, you would have to add PSU and cooling. $200. And you are being optimistic in your per board cost. $300 is. You could probably reach that price if you had the PCBs for in hand for free. So $300 + $168 + $200 for 650GH. Plus the yield, plus whatever could go wrong since that you will have to deal directly with suppliers. Good luck.
would not even attempt this. Those 5 hard to find parts are in short supply world wide. USB com parts.. They screw you on just one part you will have to find an alternate. Then run a test batch of a couple boards. If it does not work your stuck with having to change other parts on the board and then another test batch. Some of those parts are backlogged at manufacturing leval for months and you are out cash. Better off asking Mr. Teal if you could front a chip buy. Also at looking at that thred the boards are not free from problems.
