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. |

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

Are the chips available now ? If so a roundabout price ?

No they won't be back in stock until February |

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?

OG Bitcoin Miner turned Proof of Stake Validator.
Maxed out Raspberry Pi 4 8GB at 120$ a Day Revenue with ~15K XTZ Bonds in Summer of 2021.
Looking at Proof of Stake systems all across the crypto ecosystem to expand operations.

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.

Many thanks to bitfury - https://bitcointalk.org/index.php?topic=228677.msg2411923#msg2411923 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. |

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:) |

Fastest USB miner at this moment:
Doing 15+ GH sustained, hex•fury is running
from a 5.5 Volts supply.

How much? PM-ed you. Also interested in the hex*fury... Please PM for the price. Thanks. |

I have a few quick question regarding string configuration.
Q1 ) Can I assume each bitfury chip acts like a diode, and a string is just a series connection of multiple chips?
Q2 ) Do the chips have an internal voltage regulator or some kind of impedance adjustment?
Thanks in advance.

Not quite, as it has it's own consumption, not a fixed voltage drop like diodes, but the second part is correct. Q2 ) Do the chips have an internal voltage regulator or some kind of impedance adjustment? Yes there is current mirror inside the chip, which does the job. Detailed explanation is here and here is a picture of what's inside the chip (to replace Russian explanation), but the external links of the schematic are wrong |

Where do we get these to test out?? That looks like a little beast with a big punch. Fastest USB miner at this moment: Doing 15+ GH sustained, hex•fury is running from a 5.5 Volts supply. intron |

I await updates on this someone needs to compete with Bitmain. its shocking that that company came out of no-where with a developed product, and has sold from stock for months now at the best price on the market and some of the best design (could be a little more compact or a bit more power efficient, but those are little details) |
