Con - PM me a mailing address please - I have a few NF2s from my engineering units and I might be able to repair a few more. I'll send you also one of the engineering NF6 boards.

Speaking of which - mostly good news:

I'll have to find out tomorrow what have I messed up with the 6th chip (or it might be just a bad one). I also had to correct several component values, but that was the easy part

With those stats - power usage 1.05A (on a very crappy hub - voltage dropped to 4.1V!), hottest heatsink temp 68C, passive cooling/no fan.

I could send you a fully populated H-card+adapter, like you see in the picture all with good chips.
Default speed or a little overclocked from 25ghs to 30ghs(in chainminer).

pm me the address ... wish you were in Europe... but its probably US

I don't have one so cannot write the support for it. I only have 2 single chip icefuries.

8 chips seems to be the limit, after that(currently at 12 chips) it gives alot of 50% drops and reinitialising, every time it reinitialises it brings a HW error with it, most of the times.
As i said, if it truly reinitialises the chip i think it breaks the chain and has to start all over again... i dont really know.
If i tweak the osc bits for all the chips to top out at 12ghs it works, no hw errors, no drops.

The H-card works good(all good chips) with an m-board, so the card is not the problem.

The mcp2210 should be able to take more but i dont know how to tweak the software, maybe someone could help.

Yay!( Though hopefully v0.1 is bang-on )

Good bye free time ...



Hello fun!

sweeeeet :-)

btw the 50-bit stuff is meant for NF1 - from observations at around 50bits it uses 0.5Amps (hence "within USB2 specs").
In your case this doesn't really matter so - as the guys from Eagles sing - "take it to the limit"! (a.k.a. girls favorite song about credit cards )

H-card to USB converter.

Letting it ride with 8 chips 50 osc bits(to stay in usb specs as i read on bfg readme)


If someone could solve the 50% frequency drops in bfg it would run great and also overclock.
Or if there was support fort multiple bf chips in cgminer...

It needs a power lead, a wi-fi twig and some white led's.
Then it could be suspended from the ceiling and used for space heating and lighting as well.   

That's what this one's for

I would like to reserve 1 (8 board) piece + components, no stencile as i can do by hand.

DYI kits on the way! :-)



I have only 4 panels and one stencil left!
(I wish I knew that DYIs would be so popular and ordered some more panels...)

@ vs3: thank you very much....can't wait to build my nfs ;-)

yup - they're chained (a.k.a. in a "string").

Nope, no firmware necessary (since there is no additional microcontroller) - which is the beauty of the NanoFury design

However, you do need to run a small program to initialize some settings on the board (namely the product string) - which is required for some miners (bfgminer) but not for others (cgminer). But all of this is already described and detailed on the project git page.

yup as in string-like NF6. :)helped him with some realworld data measurements to verify his ideas

Has anyone managed to get more than 10 nf1 running on a beaglebone black.
It doesn't seem to pick anymore up when I run bfgminer and gets a MCP error

Nice! Let's see if it can do 15+ GH;)

If today had been any other day but 1st April, I would have asked how to input the other 40watts
