My review so far is that I am not happy with my order. I have a LA6M and received one working controller and one broken controller. The broken controller wont even show an IP. Apparently no one is doing quality control checks over there. This means I can only run 10 units while the other 10 are sitting around collecting dust
. I am requesting a replacement controller from jack.
In theory, if you chain together both 10-port USB hubs to the single controller it should work...the controller's are supposed to be able to handle upto 20 miners.
Now how that works in practice remains to be seen.
I'd also suggest you jump over to the litecointalk forums and look for the Scripta thread...DrFranz & Chirale have a Rasberry Pi version of minerd working for these...it's not perfect but it can help you get going. I've tested this version of Scripta + minerd and it does work -- the only catch is that it doesn't turn off the BTC chip so it still draws extra power....but this approach can act as a stop-gap until Jack makes this right for you.
I tried 20 on one controller and it doesnt work. It lags and they all crash after a couple of minutes. 10 works fine though. I really dont want to run the sha-256 cores because of the greatly increased energy draw.
Use a windows or linux machine and just compile cpuminer, and cgminer from the github source: https://github.com/gridseed/usb-miner . They fixed the power draw issues with this cpuminer source, so if you only intend to scrypt mine this uses the correct amount of power now. Screw the hole controller all together until a future stable release. I am running this from my Pi with no problems so far.
Did you follow any guide or post to get cpuminer compiled and installed on the pi? Are you using NOOBS os or something else? Thanks!
I'll be the first to say that I am a linux noob, the one step that held me up was installing the libraries. These might not be entirely right but its from memory, and remember I am very new to linux but I'll try to help. I am using Raspbian.
To install cpuminer:
Terminal root:
sudo apt-get update
sudo apt-get install build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake
git clone https://github.com/gridseed/usb-miner
cd /home/pi/usb-miner/software/cpuminer
sh ./autogen.sh
sh ./configure
make && make install [wait till done installing, then plug in you usb miners]
dmesg [find and copy down the names of your USB miners, they should look like (ttyUSB0) and so on.
sudo nano /home/pi/usb-miner/software/cpuminer[this is a text editor]
minerd --freq=850 -G /dev/ttyUSB[Number for usb device] [if more then one miner write -G before each] --url= [poolurl:port] --userpass=[user].[worker]:[password]
[CTRL+X]
[Y]
[name the file [whatevername
.sh]
Now run the file that you just saved.
sh ./[name of file .sh]
Should be off to the races unless I missed some step above, I am a noob but with the help from others I figured it out, this if for CPUminer which you can run scrypt pools. Need cgminer installed to run SHA-256 coins, which is also in the software folder you downloaded. If when trying to compile you get an error like missing lib something, type ldconfig while in the directory.
EDIT: There is also a installation how to in the
https://github.com/gridseed/usb-miner/tree/master/software/doc , folder.
- 10 fans running like that will generate some noise yeah. I just bought a 110mm diam grey PVC tube. Gonna have a go at doing some stuff tomorrow creating some sort of wind-tunnel. Will report back
