[EU/UK GROUP BUY] Blue Fury USB miner 2.2 - 2.7 GH/s

[Kenshin]

I had about 2.23 GH/s at first like most here. Took a look at the PCB and realized the fury chip was a bit choked to prevent heat and USB power issues. R15 next to the button was set at 22k. Read that a value of 10k would be fine. By paralleling another resistor you get R= 1 /(1/R1 + 1/R2). Set a tiny SMD pot to about 19k (careful not to set to low!) and bridged the the 22k resistor for a total of about 10k. Did a reboot and was seeing about 2.84 GH/s. High error rate and the heat sink was getting really hot. A little increase on the pots resistance landed me at at an Avg of 2.78 GH/s and a report of 2.61 GH/s. Error 4.6%

 
So you have an idea of what you should be listing in your rc.local (using Debian armhf on a SoC)

Code:

ls /dev/tty*

To make sure you are really listing the right device (a /dev/ttyACMx) on the port see what is there.

Code:

udevadm info --query=all -n /dev/ttyACM0 | grep ID_VENDOR

A fury will show:

Code:

E: ID_VENDOR=BFMG
E: ID_VENDOR_ENC=BFMG
E: ID_VENDOR_FROM_DATABASE=Atmel Corp.
E: ID_VENDOR_ID=03eb

This is even more important for ttyUSB devices since BE and BFL etc all will show up as /dev/ttyUSB* stuff.

Just change the ttyUSB0 to ttyUSB1,2,3 …n. In my case this is the cmd in my;

Code:

/etc/rc.local

Code:

/usr/bin/screen -dmS bfgminer ./bfgminer -S bigpic:/dev/ttyACM0 -S erupter:/dev/ttyUSB0 -S erupter:/dev/ttyUSB1 -S erupter:/dev/ttyUSB2 --config /home/zion/.bfgminer/bfgminer.conf

If ports start changing on you give the -S noauto a read

This is even more important for ttyUSB* devices since BE and BFL etc all will show up as /dev/ttyUSB* stuff.
Just change the ttyUSB0 to ttyUSB1,2,3 …n.

Using screen like this with the -dmS will just kick off the command and detach while the S parameter gives it a nice name “bfgminer”.  

Anyway I have my fury set at 2.7 GH/s now and that seems to be “the sweet spot” on this thing. More or less what I got with a fury chip setup I built running at 0.84V @ 2.5A clocked at 230MHz. This thing should be easy to chain fury chips on...idk. If I can get hold of some bare chips Ill give it a shot...that is if I don't get some ANT (BM1380) chips sent to me first for another project.

Somebody said something about "the pencil mod cmd" lol, sure that might work too. Not sure I personally would do it that way.

Thanks buddy, I will give it a try.

"How did you managed to get it to 2.7? I am also using the latest bfgminer. What commands are you using?"

I believe it's called the pencil command 

  Now I have coffee all over my keyboard

It seems like I have a dead BlueFury. Got them this morning. Any ideas anyone how to revive it? It shows a red led and doesn't appear in bfgminer anymore. It was there nicely for an hour until it went 'sick'. bit of a noob with those units so any help appreciated.

If you're sure its faulty, we can replace it.. but, occasionally I have to unplug one or two and plug it back in.. and/or restart the mining software.

You could always try one at a time on another computer and see how it responds to be sure.

[Markov]

No other computer to try as those at work are heavily secured. got both of them now not showing in bfgminer. will try different method and come back to you.

My other one is still hashing away like mad - MinePeon is still showing 3.5GH after 2 days! 

Oc3k, did you get my faulty one back?  Posted it yesterday.

[elpenguin]

Any updates on the faulty units?

Waiting for them to be sent.

I sent mine to you on Wednesday?

I've received yours and many others, I meant I am waiting for them to send the replacements to myself, sorry for not being clearer.

[Olly_K]

my faulty unit is being sent back tomorrow Outcast, you should get it tuesday/wednesday

thanks !

Is it still possible to order some or do I have to wait for the next round?

I'm wondering the same thing

[clarkey2013]

as above will there be another group buy?

[Orngrimm]

Is so (another groupbuy), i would be interested too....

[HellDiverUK]

I'm still waiting on a replacement for my dead one from the first GB....

Same here...

BPMC is not really showing an enthusiasm in sorting the faulty miners out... we have now had another month pass by where the USB miners we paid for have not been mining. The difficulty keeps increasing, by the time we get a replacement, 2.3GH/s will be useless.

Beastly promised the faulty miners would be replaced but it doesn't look like there are any Blues left and another batch isn't being manufactured yet. So how long are we expected to wait?
