Anyone know what the USB power draw is for each Gridseed 5 chip miner?
I measured the power draw of the usb hub lightningasic provided. It drew 2 watts with nothing connected. With 10 miners mining, it drew 7 watts, or .5 watts per miner. I don't know if that is the miner drawing the power, or the hub increasing power usage to transmit data. Ah, didn't think of doing that! Did you happen to see the difference in amps? |

I know this thread is about cases, but this Gridseed is a REAL and legit product? Would you recommend them? What issues have you ran into?
Yes, it is legit. I bought mine from here: http://hash-master.com/This is cutting edge product and as such it comes with a learning curve so be prepared. It is progressing rapidly though. I don't see any reason not to dive in for scrypt use. |

I am using the Etekcity 10-port USB hub 3A with 10 miners x2. Seems to be working fine.
I believe that Anker hub only has a 5A power supply because of the extra charging port?
Anyone know what the USB power draw is for each Gridseed 5 chip miner?
Was thinking of replacing my Etekcity hubs with ORICO A3H10 10-port USB 3.0 4A hubs but would rather not if it is not needed.
I expected to receive the Orico hubs instead of the Etekcity from my vendor but whatever...figure I got a decent enough cost on the miners that the accessories don't matter. :/

Yes, it appears to be working great. See my screenshot a few posts up. |

Thanks for this thread! Very helpful but how can you configure a coin with random block reward? I saw on Rav3nPL github settings for dogecoin for example but there's nothing particular, I wonder how it works.
There is a promising new pull request that takes the subsidy function out into a 'module' to return a value. Have been meaning to dig into it as a solution not only for DOGE, etc. but also for WDC and it's decreasing reward. Yeah I saw that for dgb, I've set up a pool with the subsidy function from the py_module made by chaeplin. Sounds promising for other alts  But if you look at dogecoin in networks.py from Rav3nPL github the subsidy function is: SUBSIDY_FUNC=lambda height: 10000*100000000. How can it works? I doesn't really...it produces blocks of only 10,000 DOGE when the SUBSIDY_FUNC is actually used. The blockchain has many examples of this happening. Funny thing is others have used that same value for other coins that have random block rewards. I was staging a protest by not running a DOGE node for a while but finally gave in  Fortunately changing SUBIDY_FUNC is not a value that requires a new fork of the coins p2pool sharechain so it can be done node by node whenever they like. I think the DGB p2pool started a new fork (changing ident/prefix) not knowing this |

whats the deal with the low WU? I've just noticed that on mine and it seems that everywhere I look people's WU is nowhere close to their hash rate. All of my gpu miners have been around 95% WU to khash.
Is this an asic thing?
Here's my cgminer running 10 Gridseeds: http://imgur.com/Lw7jEIKTruth be told I never learned exactly what WU meant...so if you're inclined to explain I'd appreciate it.  from my google searches before I posted this: "cgminer WU is the Work Utility defined as the number of diff1 shares work / minute" so pretty much what that means to me is it's the work submitted to the pool, the higher the better. The low WU numbers would seem like it's not submitting much completed work back to the pool unless I'm missing something... Thanks. Here is my cgminer running 10: https://i.imgur.com/Jq5imub.pngRunning for about an hour. You can see the one with HW of 10. 5 on one power supply is using 0.80 amps/49.3-50.4 watts (fans on - power supply model 11PWR002-360W). 10 on one power supply is using 1.40-1.45 amps/90.5-95.1 watts (fans on - power supply model 11PWR002-360W). Going to wire up 10 more on a second power supply....which brings up an interesting question. What are the miners with over 10 USB devices doing about the display of so many in cgminer? Guess I'll just have to maximize my SSH screen. Not a bad problem to have. |

Here's what my Scripta+RasPi+Andareed's cgminer looked like when I tested it Friday: http://imgur.com/38OUKz5I've stopped that setup for today as I'm trying to spend some time to isloate why that 1 miner in the dashboard seems to throw way more HW errors than the rest. Maybe a bad cable, port, or something else... Please post if you figure it out. One of my miners is also throwing more HW errors than the others when I run at 850. At 800 I rarely get any HW errors. I am guessing the one miner just is not that strong. |

Latest revision. 20+1 design. 20 miners + 1 hole for cables between sections.  Need to enlarge the holes to 97 mm. |

Cablez, are you planning to have strait or right angle plugs on the x5 extensions?
|
|

Hmmm, hadn't thought that I could run more than 5 miners on each 12v 30a 360w led switching power supply but if your running scrypt then 5 only uses about 55W!
Going to wire up 5 more on each PS since my vendor only shipped 2 out of 4 so far.

Anyone else try the already compiled version of cgminer for windows that can connect to the gridseeds? I was able to get it to connect and mine with one at a time but never anymore than that.
Had 3 plugged in directly to the computer (no hub) but I could not get more than 2 working so switching to Linux... From the cgminer FAQ: When you first switch a device over to WinUSB with zadig and it shows that
correctly on the left of the zadig window, but it still gives permission
errors, you may need to unplug the USB miner and then plug it back in. Some
users may need to reboot at this point.
I am still waiting for a powered USB hub so that may have something to do with it. |

Thank you BotwinBG and miaviator! I was missing libncurses5-dev shown as optional but is required for the text user interface. Using this now to build deps: sudo apt-get install build-essential autoconf automake pkg-config libtool libcurl4-openssl-dev libncurses5-dev libudev-dev Have a few basic Linux questions but perhaps I'll spare this thread with them and try searching. If anyone knows though: 1. how do you go in and out of the cgminer text interface keeping it running in the background? 2. will logging out of the SSH connection shut down cgminer? If so how do you keep it running? 3. how to get back into the cgminer text interface after a new SSH connection? 4. any other tips for a lowly Linux newb? |

Ok, this is more of a cgminer question but you guys are so cool I thought i'd ask here since it's to do with gridseeds  First time compiling cgminer on Linux (ubuntu server). Got tired of windows (yay!) Used this source: https://github.com/dtbartle/cgminer-gc3355...and these commands (maybe this part will help someone): sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git
cd ~
sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl3-dev libudev-dev libcurl4-openssl-dev
sudo git clone git://github.com/dtbartle/cgminer-gc3355.git
cd cgminer-gc3355
sudo ./autogen.sh # only needed if building from git repo - may not be needed with dtbartle - did with ckolivas
sudo CFLAGS="-O2 -Wall -march=native" ./configure --enable-scrypt --enable-gridseed
sudo make
Had to run cgminer with sudo for it to access the miners...even though I did : sudo groupadd plugdev sudo usermod -G plugdev -a `whoami` sudo cp 01-cgminer.rules /etc/udev/rules.d/ [restart] sudo ./cgminer --scrypt -o stratum+tcp://xpool.net:8860 -u 7Rcgymoe8TUoWkyMnVsPn9eHMaAtx677s3 -p x --gridseed-options=baud=115200,freq=800,chips=5 --hotplug 0 So...it seems to works and found the 3 Gridseeds I have plugged in (no powered USB hub yet  ) ....but I don't get the normal cgminer screen.. it just scrolls and scrolls:  Anyone? I did not see this as a dependency for cgminer: sudo apt-get install screen |

5v 1.5A for controller and 5v 4a for the hub .
You sure? I think the wiibox controller is 5v 1.0A (although no harm in using 5v 1.5A). Most USB phone charger with that ratting will work. I'm using iPhone USB phone chargers right now |

Hi, i try and try but it don't work. I do all like in the "tutorial" but i think the identifier and prefix is more... If i change the identifier of an existing coin twisted fall in a loop.

in the /p2pool folder any idea??? chain length and so not editet because try for run only thanks 4 help I have not tried this myself but someone said (although I have my doubts) that changing p2pool/networks.py PREFIX= to the same value as p2pool/bitcoin/networks.com P2P_PREFIX= works for some coins that get stuck on 'Testing bitcoind P2P connection'. Again, I seriously doubt it but give it a shot and report back. In your coin example you would change p2pool/networks.py from: PREFIX='adcc0aecfe4c04c9'.decode('hex'), to: PREFIX='ddb9b7ef'.decode('hex'), Heh, if that works I would be shocked  |

Found this from liteningasic on the board. They are providing them for free on new and old orders from them. They look rather long. 3 plugs per PCIe. Cablez, would rather buy from you...just thought you should know. I asked them for a cost but I don't know if they will sell them separate.  |

Hi Jack/asiabtc,
Please consider selling the ATX PCIe cables on their own. How much for 20 including shipping?
Also, I will be interested in the 15 Mh/s scrypt ASIC miner. Any idea on the cost? Please put me on the pre-order list.

@Cartman - That is another nice layout. I would like to mention two things if you were to use the cables I am trying to build. The first is that your vertical side to side spacing might be a bit generous for the miners as the cable legs are specified at 14in/355mm per which gives a furthest end to end of about 20in/508mm for the five plug cable. Secondly, the wire cutouts for a cable design like this one would favor a central exit point to go between levels as its basically five equal legs joined in the center. No criticisms, just some thoughts.
Thanks...my original thought was to design with the 11PWR002-360W power supply in mind but looking at the sketch you drew up of the modular cables I can see what you mean. |
