Part 3: Hacking together the Power

MOVED FROM THE END:
MOST IMPORTANTLY!

Throw away the PSU's (They suck and smell like burning electronics)


Contact cablez or post to his thread: https://bt.irlbtc.com/view/74397.0

Order QTY 4 PSU Modular or PCI-E to 3 barrel plug cables.  

This gives you 12 total plugs from an ATX PSU.
10 go to the gridseed devices
1 goes to the hub
1 is a spare

For running scrypt only you can use a 350 or less PSU for 10 units.
For dual mode you will need 1200+ watts for 10 units *(At peak efficiency) or 1200 Watts for 20 at capacity.

Now For Hacking together power









I'm on 110 here:






If you are lucky enough to have Chinese style power this would work.  This is from the lightening asic instructions.... Lol.

US POWER

get some tools, or scissors:


Cut off the end of the power cord:


Peel back the coating to show the inner insulated wires:


Strip the three wires:


Place the wires on the PSU correctly!

Grab 5 of the barrel plug cords:


#1 and 2


#3 and 4


#5


Fully wired:


Power usage while idle, IE just the PSU:

Part 5A.01: Pi

Raspberry Pi

I'll be hooking this up to power the Pi 3/12/2014 http://amzn.com/B00CBCGAL8 and testing out cgminer and cpuminer as well as casing and rack mounting the hosted set of devices I have.

Acquire an Rpi: http://www.amazon.com/s/ref=nb_sb_ss_i_0_10?url=search-alias%3Daps&field-keywords=raspberry%20pi

Dowload Raspbian from:
http://www.raspberrypi.org/downloads
http://downloads.raspberrypi.org/raspbian_latest
Extract the image file



Download SD Formatter from:
https://www.sdcard.org/downloads/formatter_4/eula_windows/

Extract and install sd formatter downloaded above.


Change the "Options" to Full and Adjust size


Confirm


If everything completed move on:


Download win32diskimager:

Extract the program and run it



I configured a few things on first boot:
Expand the image to fill the card
Change password
Change startup method (Text only)

Enable the root account

ssh back in as root and change the associated paths and groups

ssh back in as miner and install the pre-requisites

Build cgminer:

Build cpu miner:

Link the build directories for convenience:

? Profit ?

Install Pre-Requisites:

Grab possibly needed packages:

Install curl and jansso packages:


Build cpuminer from git:

*** For ubuntu 13.10 ***
Install the correct automake version so cgminer builds

Link the Jansson Libraries to fix:

*** END ***

Build cgminer:

Link the build directories for convenience:



If all went well you will have the miner installed.

Now DO NOT PLUGIN the USB yet just the power cable:




Plug in the USB cable to the computer and device:



Syslog results



*You might havedev/ttyUSBX not ttyACMX

If you don't want to run all of the miners as sudo/root
Where <username> is your username: sudo usermod -G plugdev -a miner

Now run the miner process:

Or using CGMiner Syntax


It appears you can't combine devices to one line like this: (worldlybedouin,Powell)


I use dynamic pool files but something like this will work:


SCREEN USAGE
In order to keep the miners running when you log off ssh you will need to use screen:

to list screens if you did not add your user to the plugdev group you may need to use

to join a screen

Press <ctrl> A <ctrl> D (or <ctrl> AD) to exit the screen session.  You can then exit the ssh session and the miners will continue to run.

YAY means YAY



How I run the 10 miners to 10 separate pools:
***WARNING: This assumes you use username miner and home pathhome/miner ****
This also assumes that you have added your user to plugdev or are using root with (sudo -s)

1) Create 10 pool files named pool0.sh to pool9.sh
2) insert the FREQ NAME and POOL variables into each pool file
pool9.sh
3) make the mine.sh script to execute the miners

After running mine.sh for this hosting thread https://bt.irlbtc.com/view/471764.0 I have the following screens:

To mine to my donation address for this guide:

Breakdown:  NEEDS HELP

Execute the Miner:

Enable Gridseed configuration flags

The Serial/USB com speed (Don't Change)

The chip frequency in 50 Unit steps from 600 to 900:

The number of chips on the device (Don't change for these devices)
*Change if you get a 10 or 25 Mh/s GridSeed box
*you bastard
* I want one

The number of boards/modules/devices per com port (IE 1, don't change this)

Communications method used to talk to the device board (Don't change)
*Correct me if I'm wrong

A seemingly arbitrary number until someone tells me what its for
*The doc says 11 I'm sure there is a range

I'd guess this allows devices, modules or chips to be added/removed while the miner is running?
*IDK and IDC

Standard pool config

Mining:



Mining per device vs all devices:



Quick and dirty Bus:Device:


Run one or more devices using cgminers --usb flag https://github.com/ckolivas/cgminer



or etc.

Part 5A.3: BTC/Dual Mode

Once you turn on BTC mining you have to attache to the LTC proxy in order to mine in scrypt mode dual mode.  Or unplug the devices and replug them so they show up as ttyACM# again?

Once you are running one or more devices in SHA mode you can start Scrypt mining in dual mode with:




Can I run to 10 pools this way?  Let's find out.

Get a copy of the pre-built cgminer for windows: http://cryptomining-blog.com/wp-content/files/cgminer-3-7-2-gridseed-windows.zip

Extract it

Open Device management: Press Window Key + R to open the run dialog or navigate through the control panel


Plug power into the gridseed(s)

Plug USB to the gridseed(s) and to a powered USB hub.

Open the extracted Cgminer folder:

 
Edit LTC_ONLY.bat to contain your pools and frequency



Save the file

Double click to run.

Part 7: FAQ and things that need to be added

Q: I get ttyACMx vs ttyUSBx and no shares are submitted even though the miners work and pull from stratum
A: This is normal.  Some linux versions may give you ttyUSB vs ttyACM.  Shouldn't matter. Post if it does.

Q:  Cablez's page he mentions several sizes/types (2.1/5.5 vs. 2.5/5.5)
A: 2.5mm plug http://imgur.com/a/aviaS https://bt.irlbtc.com/view/74397.0

Q: you mention 11 of barrel plugs...I don't understand what the 11th one is for if I only have 10 miners
Plug # 11 is for the USB HUB !!! Awesome!

Q: Would you consider using Cablez's micro-USB to ATX PSU power cable as well?
I've never seen that, I'll put an order in and Yes!  

Q: One thing though...    You say to throw away those PSU's that come with it and get a modular PSU capable of 600+ watts
A: I just buy modular cables from cablez here on BTC talk.  He can make just about anything for any power supply.  I plugged all 10 gridseeds and the hub directly into my corsair AX1200 using custom made modular plugs.  You could keep the included PSU's or use a really low wattage PSU to only run in scrypt mode.

Q: my devices won't mine and syslog spits out a bunch of modem manager lines:


Q: When I start cgminer/cpuminer/xxxminer no shares are submitted and syslog spits out some weird errors and I get these errors.  And libusbnot

Use a fully compatible USB a to b mini cable supporting power and data and ensure you have a full 12v supply with sufficient amperage.


Q: can xxxminer based on cgminer tell me how many devices are available?

There is some logical limit per PCI-E lead that would make 3 devices the max.  I actually have 4 per right now, and I was thinking about 10-20 per lead since these are such low wattage.  The power guys (Cablez) might be able to give more specifics.  Basically if you plug to many in and they ramp up to max power you could melt some wires and plugs.

Lol.  Just because I sell live unicorns doesn't mean all ASIC's are vaporware

Get back to me when you have Petite Lap Giraffes.

Great work!

I am thinking about buying a few hundred of these round Asic miners.

1) What will be the best way to run as much miners as possible on one controller PC RPI?

2) What software would you use?

3) What power supply would you use?

Any input is more then welcome!

http://cybtc.com/article-468-1.html


I think if I build a serial cord to the com2 interface I can dual mine on linux?

Excellent work! I enjoyed reading it. Very thorough,,,but...I have a couple questions.
What does FML mean?
What are the commands for telling the miners to run Scrypt only or SHA and Scrypt simultaneously?
I'm running cpuminer 2.3.2 and using Winblows 7
I'm going to try the freq' to 850MHz
Tried 750 last night, hashes went south so I backed off. I was thinking of trying it, especially after finding and reading the mfg spec' sheets. They'll go even faster than 850, as I recall.
Thanks!
