I have some questions about the NF1 (0.7). (yellowjacket)

According to the parts list, CF1.8-1 is a 100nF capacitor.

But it looks nothing like the other 100nF capacitors on the schematics.

Also, what are those small gray circles on the left.
And what is the purpose of the contacts right of the bitfury chip, no components are going to be placed there.

thanks.

I register my interest in a possibly upcoming NF6 DIY kit.

I take it that you would do a diy kit for the NF6?

And while we set up the NF6 production line and clarify all details ... I got bored and tweaked the board a bit (removing a few extra resistors and some other minor optimizations) .. and figured - it would be interesting to see how did it evolve :-)

So - here it is - version 1 vs version 2:

then, version 2 vs 3:

or all changes between 1 and 3:

Nice, well done:-)

Thank you, Sir! :-)

And to be honest from the few people that deserve a lot of credit for NF6' existence there are two that stand out:
you - for proving that it is actually doable, and
KNK - for confirming the minute detail that makes it all possible! (which also saved me a dozen chips:)

So - Thank You!

Should our paths meet - drinks are on me!

Praise should go to Valery (bitfury), he
came up with this brilliant 'string' idea:-)

First: simoncc - nicely done! :-) And thanks for sharing!

Onto the NF6 story - v0.2 of the design is now confirmed with both gen1 and gen2 chips!

Here is how things look like with Gen1 chips:

This is with a crappy power supply (4.6V) and 54 bits, somewhat inferior heatsinks, a tiny bit of airflow, temp 46C and 65C (on the second one heatsink faces downward and that's chips temperature). I haven't checked exact current usage but from indirect measurements it is around 1.3A (which is a bit higher due to the lower voltage, or around 6W total)

Or to summarize it - with Gen1 chips 9GH would be around the norm, and over 10GH with a bit better hub (that provides actually 5V). On a slightly over-voltaged hub (5.25V) it should be able to hit even 12GH and above.

And the screenshot below is with a mix of chips: one NF6 with Gen1 chips and one with Gen2 chips:

Same hub, power usage a bit higher (and voltage down to 4.3V), speed 54 bits for both, a bit better heatsinks (the Gen2 with the best I have around), temperatures: 50C on the gen2 and 73 on the gen1 (which is also facing down so not the most efficient position anyways).

Judging by the low error rate I can probably squeeze out another 0.5-1GH out of each.

And I'm actually rather surprised that I see a stable 11.5+GH with such a low voltage on the Gen2 chips. On a better hub it will certainly exceed 12GH and with a slightly overvoltaged one (5.25V) it will very likely exceed even 15-18GH.

The Gen1 chips in this screenshot are from the older series with datecode 1337.

There are also differences between the various production dates in the Gen1 chips - the first 2 boards have chips with date code 1404 (which were from the last series - I got a few of them forwarded from bitcoinvalet's last group buy) and I am a bit surprised that they perform slightly worse than the older chips that I had around with datecode 1337 (which were leftovers from the NF1 series).

Bitfury Gen2 chips were from the first samples available for purchase from punin (datecode KCTMS):

One day someone there asked me one question "How to chain NF2s together and access them by one USB interface?"

I had a look at my NF2 board, and found out how to do that. Let me show you the picture:

WARNING HERE: I HAVE TO SAY ONE THING THAT I DO NOT REALIZE NF2 CHAIN HERE BECAUSE I HAVE ONLY ONE
BF2. SO YOU CAN TAKE THIS FOR REFERENCE ONLY. NO GUARANTEE AGAINST DESTROYING DEVICES...https://dl.dropboxusercontent.com/u/23682587/nf2-chain.jpg

1. unsolder the parts in orange rectanges on 2nd NF2. ( 1st NF2 does not need any modified, only 4 flying wires later...)
2. there are 4 red circle on 1st NF2, and there are 4 blue circle on 2nd NF2. Connect red 1 to blue 1, R2 to B2, R3 to B3,
   and R4 to B4 by flying wires. Note: make sure wires 1 2 3 are the same length.
3. if you want to chain the 3rd NF2, unsolder the parts on 3rd NF2, and connect Red circles on 2nd NF2 to Blue circles on 3rd NF2,
   and so on...
4. if you plug these chained NF2 to the same USB hub, GND plan should be the same. No GND wire should jump each other.
   Yellow circle in the picture is GND point I use.

AGAIN HERE:
WARNING HERE: I HAVE TO SAY ONE THING THAT I DO NOT REALIZE NF2 CHAIN HERE BECAUSE I HAVE ONLY ONE
BF2. SO YOU CAN TAKE THIS FOR REFERENCE ONLY. NO GUARANTEE AGAINST DESTROYING DEVICES...

You do not populate the parts in oragne rectangles on the rest 7 NF2 boards if you
have DIY kit from vs3... and you can save a little bit of money by this.

Has anyone got Cgminer to work with more than one chip?
I cant figure out how to make the code simoncc provided.
If someone could post some instructions... i would be very happy

You can download cgminer from official Con's git, then replace all files related to mcp2210 and bitfury from simoncc git then compile with --enable-bitfury.

I think that should work ... Roll Eyes

Can u guys get more hashing speed out of them? Is this the same chip as the nanofury?

The chip is the same, but the board is not (there is a dual chip NanoFury, the NanoFury II as well, you can compare the two)
For the device in your video, try this thread instead:

In another test I tried two different heatsinks - one from the NF2 series (very high performing - probably the best I've seen so far) and another generic one. The generic one had about 8-10C higher temperature, and when pushed very hard (and no fan) the board got to 105-108C and I started seeing a lot of hardware errors.

I've relocated it vertically - again no fan, and that seems to be fine - temp is 76C as of this moment while it does:
NFY 0: | 10.37/10.22/10.89Gh/s | A:87 R:0+0(none) HW:75/5.0%

Thats BIFURY, same design but communication is done through another chip and through firmware.
NFx design comunicates with the chip aproximately directly...just an usb-spi converter.

NanoFury and RedFury..icefury...etc are not the same.

Download this tool to modify the product string of MCP2210 : http://ww1.microchip.com/downloads/en/DeviceDoc/MCP2210Utility_v1.2.1.zip
Read, modify and configure... quite easy. If you use zadig to access MCP2210, you have to remove/uninstall it and change to windows default HID driver such that microchip can access MCP2210 correctly. I will put my source to github here tonight, 'cause that is at home, not in office.
[/quote]

I thought cgminer was suppose to work with the zadig drivers... excuse my ignorange im not very good at software.
As Taungeran said earlier in the thread, mcp2210 is limited by the hid drivers as they are designed for relatively low output of information, limiting the NFx to about 8 chips... as i found out.
