Thank you sir the git is working, now the autoconf is taking forever. I will sort it must have missed a package.

I concur! Do NOT use that splitter or the pigtails (wires) coming off of it singly either!
They are designed to carry 500mA or less! A miner will pull up to 600mA in SCRYPT mode, usually less but it can peak that high. Do the math. It won't work out well for you if you don't head our warnings!
Try these http://www.amazon.com/dp/B0058RLD9C/ref=pe_385040_30332190_TE_M3T1_ST1_dp_1 with the appropriate 'paired' wire i.e. - 14ga Stranded Copper THHN - minimum just in case you ever do decide to run SHA. RED And BLACK are the idea colors. RED = + / BLACK = - Clearly marked on the adaptor!
Practically anyone can make this work! And Yes, they will work perfectly!
16 gauge stranded copper will work though if you are dead sure you will never run in SHA mode.
Good luck!

I just rebuilt from the updated instructions in the OP.

Yes.  I just had that issue...

Nice! I like the layout. Nearly exactly the same as my stacks are going to be when I have enough miners.
One small point though, if you want those single end fans to do some good, they need to be ducted so the air from the fan is pumped through the fins of all the miners in that row.
Otherwise the fan is simply cooling the pod it's bolted to and maybe helping the one next to it a bit but the rest are simply convecting their heat in to the surrounding atmosphere.

Probably best to just have all of them 'fan-less' and be done with it.
Fans look cool but I'm afraid they are wasting 90%+ of their energy in their current role.

I have my current 6 units all being cooled via a small amount of air flow from the pod in the middle of them which has a fan on it pointing downward with the bottom (as with all of them) held about 3/8" or so off the bottom with the fan screws being used as posts screwed in upside down in the fan mounting bracket. The air flowing out and around the middle spreads its air around the surrounding pods keeping them all just at or below ambient - within 1 or 2 degrees F of each other

The more I think about it, the more I dislike the idea of ducting them together like that which will add complexity and ugly the rig up. Also there is dust accumulation over time to worry about if air is forced through the fins. That stuff can get messy and cumbersome.

Running in S-Crypt only they don't really need fans anyway. None of them!
So save that .25Amp per fan and put it to use making you a bit more money!

Again, nice looking rig! Very practical layout and easy to manage!

anyone else having issues with the git address in the guide

miner@raspberrypi ~ $ git clone https://github.com/gridseed/usb-miner/tree/master/software/cgminer
Cloning into 'cgminer'...
error: The requested URL returned error: 403 while accessing https://github.com/gridseed/usb-miner/tree/master/software/cgminer/info/refs

miner@raspberrypi ~ $

That's kinda neat. Looks like you could have routed the power/usb in-between the 80/20 rails. I imagine the picture is upside down and that the miners are resting on top. Did you make that yourself?

Wonder if you would have kept the fans on all of them if it would have made a big turbine with a lot of air getting pushed all the way through....hhhmmm, makes me want to rethink a case design.

Raspberry Pi is the cheapest way to go. Get a bunch of 7 port single level hubs, and you can put 98 on one Raspberry Pi. Whether it can support that many, I have no idea.

Nice ! I'd like to see more.

But be careful : you need to isolate the red 12v wire you cut from the fan. If for any reason the wire touches the heat sink, your unit will make fireworks.

What? I stated what?, where? Please provide the link. I make lots of opinions on several different threads...
Tanks!

Hello Emoomjean. You seem pretty experienced / educated on USB gear.
Can you point me in the direction of some decent technical information on USB systems and how they work,exactly?
I'd like to read up on their nomenclature - in full. I need to learn this stuff,,,,fast!
I am not fully comprehending how 4 -127 device capable ports are going to help overcome the problem with the semi-unstable performance of all the hubs and ports downstream from there. Again, not arguing, just want to understand, exactly how that works - in detail.
Also, does anyone make an enclosed version of that unit for Win 7 PC's with USB 2.0 High Speed ports.
Thanks

Thanks all for your help. Got it working now. Was a misconfig in the cgminer.conf file

Our current setup so far:

I plan to start a thread with our full setup and a video walkthrough when we get to a certain point.

I am using 5 on each in ltc only.

Try a different pool.

Well if shares were not being accepted and I didn't see any Kh on the pool then I would say that is the problem but share are being accepted. So it must be something else.

Agreed.
