[Announcing] MineNinja - BeagleBone Black Bitcoin Mining Platform

[sahkan]

Great job on the Beagle Bones. Is the case from the picture the one that I got?

Got it Friday night, it has been running the proxy for the blades ever since. I love that new 5W server! Thanks!

[firefop]

So far I like this product. Very nice offering and needed as well.

It's the twin sister to the one you got (with a slightly repositioned mircoSD slot), and it will be heading off to it's new owner in Sweden in a few days when we catch up with case production. Glad to hear its working well for you - thanks for your support!

Looking very nice, and useful
Congrats

Any thoughts on using the 5v from Pin1 of the floppy connector of an ATX power supply to power these?

edit: or a molex or sata connector for that matter?

Is anyone successfully running more than 7 USB Erupters on the MineNinja?

cgminer is "hashing" all of my erupters, but work is only being submitted on the first 7. 

1. ls -las /dev/ttyUSB* shows yields all of the ttyUSB from 0 to 32. with dialout access.

2. If I change the tty/USB number around in cgminer.conf, I have functioning erupters on every hub.  The hub I'm testing is a 49 port Cambrionix which is flawless on my Win7 box.

I can make 7 erupters work at a time, in every socket of every hub.


Frustrated, any help is greatly appreciated.

I have had 12 running at once, and currently am running 10 (that's all I have left).  Did you modify the startup command in /etc/init.d/cgminer?

The fact that you were able to get them to show up in /dev/ttyUSB is promising. 

Are you powering the BeagleBone using a 5v power brick plugged into the barrel plug?

Yes - using the 5v power brick for the BeagleBone.

Every one works in every slot, but only 7 at a time.

I did modify the /etc/init.d/cgminer.  I tried a few different combinations with the -S switch with the same results, then I just switched to this when I got sick of changing the numbers repeatedly:

screen -dmS miner /usr/local/bin/cgminer -c /etc/cgminer.conf

cgminer.conf

Code:

root@mineninja:~# cat /etc/cgminer_conf2.bak
{
"pools" : [
        {
        "name" : "stratum.bitcoin.cz",
                "url" : "http://stratum.bitcoin.cz:3333",
                "user" : "xxxxx",
                "pass" : "xxxxx",
                "pool-priority" : "0"
        },
        {
                "name" : "stratum.btcguild.com",

I'm guessing the problem lies somewhere in cgminer.  I'll gladly donate a BeagleBone to kano if he wants to try to sort it out.  The 3.3.x versions of cgminer have even more problems on BBB/Rasp Pi, so I can't suggest that updating would do anything other than just make the problem worse.

Agreed.  3.3.1 brought all kinds of good error messages. 

I haven't ruled out a hub issue, since this works so good on Win7.  It just doesn't seem plausible given the devices check out from commandline.  I have another low power box that I can use to test Ubuntu with the hub.  Maybe we'll get some forward progress from kano on the Beagle. 

Very cool device and well done on MineNinja!

Update and bump for this cool platform.

I've been playing around with the BBB and the mineninja image and through dumb luck managed to get cgminer 3.4.3 to compile and run. 

I've been out of Linux for so long I've forgotten how to do easy things without google, such as piping output, ala "xz file | dd of=newfile".  It literally took me two hours to flash the BBB with the stock MineNinja img. 

I wrote the image to a 4GB sdcard.  There was enough extra space to create a third partition on the card for storing the xz file.  After you boot from the SD, extract/write the image to the emmc using an xz | dd command.

Neither libudev nor udev-dev installed, seems to be an issue with BBB or Angstrom.  After banging my head against the desk trying to figure out how to install libudev, I found a google group post for a BBB libudev problem.  The BBB group post recommended systemd-dev.  After I tried it, smooth sailing.

opkg install systemd-dev

libsub-1.0.16-rc10 - http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.16-rc10/

Compile CGminer 3.4.3.  Disable/modify init.d/cgminer.  Reboot and test.  Edit init.d and cp cgminer over to /usr/local.  Reboot, hash.

YMMV.  Have a backup.  I messed with udev and libudev for quite a while figuring this out.  I have not reflashed the BBB to recreate the solution.

Seemed pretty happy around 50-55 erupters.  Really dogged out over 60 and crashed at 66.  I ran 48 all night on the same hub which previously gave me problems earlier in this thread.

[MWNinja]

Thanks for the update, we'll be releasing a new image for MineNinja "soon" that has the latest and greatest cgminer (and perhaps bfgminer).

As for flashing the BBB our wiki has pretty good instructions: https://github.com/slayersoft/MineNinja/wiki/Flashing-the-BeagleBone-eMMc

What is the easiest way (How do you?) to update the image on your mineninja host if you need to/want to?  Also, have you looked into any of the other miners yet for compatibility such as bfgminer/bitminter?

Thanks!

So, why have you removed credit of the original authors from the GPL source code you're using?

https://github.com/slayersoft/MineNinja/blob/master/WebUI/footer.inc.php
Original: https://github.com/hank/ANUBIS/blob/master/footer.inc.php

I know you forked from me since you're using acuity (which I added to pshep's version).
  
https://github.com/slayersoft/MineNinja/tree/master/WebUI/css
https://github.com/hank/ANUBIS/tree/master/css

pshep's for comparison: https://github.com/pshep/ANUBIS/tree/master/css

I left credit to pshep in, and you should be leaving credit to both of us because that's how GPL works.  If you need to take it off of the interface footer, do so, but take yourself off as well and simply say "This code is GPL" or something like that.  Then, make an AUTHORS file in the WebUI root and credit everyone.

I also see you removed the link to the contact page, which also credits myself and pshep (it's even still in your repo):
https://github.com/slayersoft/MineNinja/blob/b7580e6871174b2ed6707893964bf1203f2af189/WebUI/contact.php

(Cleaned up for readability):

You can msg me (<a href="https://bitcointalk.org/index.php?action=profile;u=47656">p_shep</a>) on bitcointalk.org or have a look here: <a href="https://bitcointalk.org/index.php?topic=57342.0">https://bitcointalk.org/index.php?topic=57342.0</a>

Anubis has taken many hours and hard work to get to the stage it's in. If
you like Anubis, any donation will be appreciated:

If you like this theming (dark/black), it was done with a forked copy of the
original software by <a href="http://github.com/hank">hank@github</a>. Maybe
you could send a small percentage of what you sent to p_shep to the following
address: 1ErikgLXAmxuTk76tdCrRW3iLnX1GS8mFd

You might want to go delete that if you want to continue making it appear that you originated all this code, and if you want to prevent myself and pshep from receiving donations.

[MWNinja]

I left credit to pshep in, and you should be leaving credit to both of us because that's how GPL works.

That's not how GPL works, basically I can modify GPL software anyway I want, make my own fork, and there's no attribution requirement.  The only requirement is that the derivative work is released under the GPL, which it is. BTW I gutted out most of the acuity template.  You aren't going to get any donations anyhow.

https://github.com/slayersoft/MineNinja/wiki/Flashing-the-BeagleBone-eMMc should help, basically boot your BBB from a microSD, then use dd to write the image to the eMMc.

Hi i wanted to buy one or two block eruptors but, the problem is that when i put my billing adress it says that u cant deliver to spain, so i cant buy anything?
Can you do something to ship them here?

Just thought I'd point out that BBB may have some bandwidth issues.

In case people wonder why their CGminer's hash rate doesn't match up, not even close, to what a mining pool says.

I'm using BFGminer and 14 Erupters. With '9', I get about 0.89% HW errors. With '14', I get 10%. All using the same Share Difficulty. I take the entire rig setup and plug it into my Windows box and get 0.98%

Setup:
.............................................-> 9 port self-powered HUB-> 9 erupters
BBB -> 7 port self-powered hub [
.............................................-> 7 port self-powered HUB-> 5 erupters

*Just swap the 'BBB' for Windows, and it's 0.98%.

This leads me to my conclusion that BBB (and possible Pi) can't handle the [read: Process] USB 2.0's full bandwidth.

*BBB is being powered via a USB cable as the DC port failed after about 4 days  . I do have it plugged into a 5v,2a (same as the power block that was recommended for a BBB) "Fast Charge" port. Hopefully the thing won't catch fire

We had much better luck with Cgminer 3.6.6, had up to 40 block erupters running solid.
