Any ETA on these? Pumped for 15 gh/s usb sticks xD
Me too please. I had already PM'd you though. 
Thanks
PM-ed you.
Thanks
Intron - please PM me details about the hex miner, VERY interested xD

Same here please, want to buy at least one, awesome design!

The hashrate of a strings design is heavily dependent
of the supply voltage. You are sure this didn't change?
The PSU is 24V +- 1% not 7% and the power (edit: at the wall) is the same, while an increased voltage should have been increased the consumption too.of the supply voltage. You are sure this didn't change?
My strings are of 28 chips or 14 per 12V instead of 15 as in your case. The last chip is replaced from a diode to get the IOVDD (wasn't sure if IOVDD = VDD will work, so played safe) - this is the only part that may affect the overall per chip voltage ... in case the voltage drop on the diode decreases with the time, but then the effect of the temperature would be much more, which is not the case, so my (current) bet is on either CMQ (+-) resitors change in value (= less unused current for balancing) or some kind of resonance of the chip clocks
Only if there are chips first 
Waiting since November to build some more strings.
One strange thing i have noticed, is that the hashrate is increasing with the time without any other changes - started with 245Gh and now at 265Gh/s ... ~7% increase it's like with the time the clock stabilizes and increases or the chips get in some kind of resonance between themselves.
@intron do you have similar experience with strings?

Very cool.
I can't wait to see them hit the market.

I am definitely interested in them when they come out. Looks great so far.
If you need someone to test any units for you let me know.

Thank you for the offer, but we are 'testing' the hell out
of these things already. And for more than Two Weeks (tm)

We are working with others to get both the 15-chip One String Miner, as well as the 6-chip hex*fury produced.

I'D like to buy one can I get directions where to buy from?

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)

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.

Q1 ) Can I assume each bitfury chip acts like a diode, and a string is just a series connection of multiple chips?
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
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.
