I am encouraged by the creativity of this forum Great work.
But, the withdrawal of GPU mining in the near future, why is no one designing a board that will plug into the empty PCIe slots? I would think a 2 to 8 chip board with cooling would be a perfect fit, as power is right there with the unused PSU connector from the retired GPU. This might be a future consideration, as I see the small boards as expensive in relation to larger boards, price per square CM per hash rate.
What are your thoughts?

* USB is a much simpler (and cheaper) interface to work with than PCI-E for development of this type
* A single host computer can have a lot more USB devices connected to it than PCI
* The host doesn't even have to be a PC- it could be a raspberry pi or TP Link router
* The boards in development now use the PCI-E power connectors anyway that GPU's use

Yep -- say you currently have 10 computers with 6 GPUs each.  You could replace each GPU with 6 ASIC PCIe cards and still run 10 computers.  Or you could pull all the power supplies and run 60 USB ASIC cards off of one raspberry pi.  The pi uses onlye 5 W -- each computer before was using ~ 50W each, saving you 500W.  And you've cut your maintenance by a factor of 10 (firewall, system updates, etc).  Everything is centralized.

Price is 19.50 USD per piece. Shipping cost and taxes are not included. So, I think the price will be around 20 EUR/piece (or about 25 USD/piece).


Let me guess you found them on Alibaba.com??

They cannot deliver.

Sent you a PM, not sure if you got it.

But are you planning to do a single ASIC board (USB powered) with Bitfury chips?

nice man! so what were the initial costs for that prototype? can you give us any estimations?

very rough estimation for the prototype is 70 Euro + Avalon ASIC. But the PCB alone was about 40 EUR (I ordered only 5 pieces).

Lower hash rate than the USB Block Erupter, but more beautiful.

Let's wait for some overclock and I hope aauer1 will sell some of those Gizmos, as I would love to buy one.

The hashrate of about 211 MH/s wasn't really correct because it was just running for 15 minutes. The ASIC is clocked with 256MHz and performs 256MH/s without a heatsink. I also tried 300MHz but then I think I need a heatsink. For now, I'm just running it at 256MHz.

Good  Smiley

+1 Interesting. Nice to see people trying innovative ideas.

Come on friend make bfl chips board .it is not necessary USB power.can you make it without USB power I think better is 4 chips per board  Smiley

Outstanding. Would be real interested inBFL application.
Have chips on order.

Just got the board to hash! Now the proof that the board is mining:


Nice work. Looks good! Are you going to try and overclock?

And the assembled board:

Wow! I like it more than the USB Block Erupter... and what about mining results?

+1 for the Bitfury chip and please, can we just stay away from BFL?  Why do we keep plugging them after all that has happened??

Right now, I'm waiting for my PCBs for the Avalon miner. In the meantime, I thought I can try to make a board for BFL ASICs, too. So, I sat down and played around with my CAD software.

Delivery not certain. Better to work on a BitFury design as that is more in line with Avalon chips right? Same footprint.

That was fast... hashing already? I guess with such a large surface area.. you can passive cool it even with overclock.

No it is not hashing right now. I have to make the firmware for the microcontroller. Maybe I get it hashing this weekend (depends on the weather  Smiley ).

Got my PCBs for my Avalon USB miner! Let's see if it is working!

Yep, you're right. Bitfury has the same footprint as Avalon chips. And bitfury chips have higher throughput with lower power consumption than the BFL chips. With Bitfury it could be possible to make an USB powered miner with more then a 1GHs/s (the specs are specifying a hashrate of 5GHs/s with only 2.5W power consumption).

That be good... I don't think there are any BitFury USB designs right?

I think somewhere he posted the design, unsure. You need to mine that thread for info. if its not usb, then i think its easy to adapt to usb.
