Intron, Cscape,
         Very nice work! Just when i thought I've seen it all, you come a long and surprise me.
in your opinion, what are the possibilities this will become a standard with new ASIC chip designs from others?
Hopefully other ASIC competitors will take notice.
No DCDC converter with only two layer PCBs is a huge win in price reduction.


To be able to make a string design, the chip must provide
for a method to shunt the current that is carried by the
string when it is not in full operation. When you got that
one right and have some means of level shifting of the
signals going up and down the string it should be possible
whith any chip.

And Valery got that right:)

Many thanks to bitfury - https://bitcointalksearch.org/topic/m.2411923 he designed the chip with that in mind ... so far no one picked up that trend and we are still far from the best design of a chip, but if he fixes the few small problems for V2 (which i am sure he is working on and wish him a luck with that) - that will be the best of both worlds: high hashrate and cheap board.
Many thanks to Intron and Cscape for their work too - they have showed to the public that it's possible and hopefully more chip designers will at least think about the possibility.

I really like the One String miner. Wish i had some bitfury chips right bout now. Is this what Dave was carrying with him at Inside Bitcoins Las Vegas?

Don't think so:)

Are the chips available now ? If so a roundabout price ?
No they won't be back in stock until February

I think this is the best bang for the buck you can get out of bitfury chips in a USB stick form factor.

Yes, that was the idea. Total BOM cost is about $4, excluding bitfury ASICs.

awesome. someone actually made a 6 chip version. i'd thought about making a 6 chip stick when the sample chips first came out (but our first design failed and we gave up)...I think this is the best bang for the buck you can get out of bitfury chips in a USB stick form factor.

nice USb, but i dont understand why - it draws far too much power for a USB port, so for the effort of getting it to work it seems like a much easier idea to go with the one-string or other design that uses 12V and holds more chips

It takes about 2.5 Amps, you can power it from
an USB hub. And it also has a seperate power
input that feeds the bitfury ASICs. When this
option is chosen then the USB has to power
only the processor.

And indeed, we were just playing around a bit...Wink





Extremely promising design. Congrats Smiley what is the controller chip that you are using? Thanks!

So it's not powered from the USB, but from an external power supply ?

Even at the minimum 0.6W/Gh the BF chips are capable of - 15Gh is 9W, which is not possible from a single USB port be it even 3.0
With 2x USB 3.0 or 4x USB 2.0 it is doable
