Depends on if you are running LTC or LTC+BTC. The current draw per GSD is about 1A for LTC and about 8A for dual-mode.
If you are doing LTC only, then you probably need about 10A for 5-8 GSD devices. You don't want to run the PSU at 100% (probably cant, actually). I think there is suposto be a 20% margin, so 10A per 5-8 is probably about right.

Got a link for those $2 bricks?
I'd like to see what you're talking about.
Thanks

So not enough juice in 1 brick to run all 10?  I've had them running off of just the one for about 7 hours now, wondering if I'm pushing it though?

Also, I had rigged an old power supply to run my first 20 gridseeds and that works great, but these new little power bricks with the cctv DC plug splitters are sooooo slick. I see the 12V power bricks for like $2 on fleabay...is there a reason we should not be using them (scrypt-only) for say 5-8 Gridseed units?

Probably 1 brick per 5 GSDs. That's how my kit came anyhow, 2x 12V @ 30A PSUs, 5 GSDs per PSU...

Hey guys, I got two 12v power adapter bricks in my latest Gridseed order (10 units)....what on earth is the 2nd brick used for?

I'm using a config file. Add "--" to config parameters to use them in command line. "api-allow" is an IP address of a remote host. If you want to use the API locally you don't need that parameter.

With my setup I am running a Raspberry Pi 11 Gridseed units and dtbartle cgminer.  I use two Rosewell 10 port hubs and was having tons of problems with my Pi restarting, dropping USB wifi, dropping ethernet.... I tried everything I could think of to fix the problems.  For my setup I think I found the culprit, which was my USB hubs.  I found that they were backfeeding power to the Pi which was causing the above issues.  For me, my solution was to cut the red 5v line in the usb cable that goes from the Pi's hub to the Rosewell USB hubs.  After I cut the 5v line the hubs would not turn on since they needed the 5v to turn on.  I used my multimeter to find a 5.2v open pad on the USB hub and took the cut red 5v line from the cable and soldered it to the hub so they would turn on.  Its now 2 days after the mod and it has been rock solid so far.  No reboots, no lost wifi signal ( i use a wifi dongle ).  Not saying that this is the problem with others units but for my setup it was the Rosewell USB hub backfeeding power.  Before I figured this out I thought that the Pi was just not capable enough to run stable and that getting a different board would solve the issue.  I bought a Cubietruck and found that I was having similar problems as with the Pi which is when I started reading about USB hubs and backfeeding power.  May be worth investigating for others.

can I see your command line (absent your stratum and worker names of course )

So I cant run more than 10 without getting a "zombie" error.

Did you do anything special?

How exactly do you want to use it? I have one instance talking to a monitoring application on another computer, another instance is feeding into Scripta web page. API works just like it would on any other cgminer.

has anyone gotten the api working with cgminer on rasberry?

TIA!

For people using 1-20 gridseeds a hub might matter.  Once you start hitting hundreds hubs become about cost.  I can use an $8 10 port hub and hook a lot of grids to a linux system.  It's not worth the effort or cost to use 1 pi per 5-10 miners.   At the current rate of scrypt reward drop it isn't really worth spending more on PI's than I would spend on old linux boxes built from spare parts.

cgminer on my Pi stopped working after about 6 hours.

mine is  locked up now and I'll reboot it when I get home after I get home and try applying the slub_debug=FP  and see how it goes

It's a community guide at this point.   So sorry but Your fault

Give me whatever should go in there and I'll change the OP

Have you tried differents HUBS? Think it matters?

i found some neat pictures, https://www.dropbox.com/s/yes569a9y8d6ybi/HASHRA%20SET%20UP%20GUIDE%20FOR%20WIIBOX.pdf (page 4)
but mine's broken...:/ can't find it on router and green light isn't on for more than 2sec

Micro USB power

USB to hub

Ethernet to ethernet.

Im interested in how these things are suposto be connected as well.
Got several in my order, but not sure what the wiring is suposto be.

HI! i have a Gridseed Wiibox controller ( looks like this http://www.scrypt-hash.com/wp-content/uploads/2014/03/wiibox-150x150.png )
And i am supposed to power it with micro USB? Like a phone charger/ microusb-usb and plug it to my usb hub?
Thing is there's a green light and it's on for like 3seconds then it goes black every time i plug in the wiibox controller. Is it broken?
Do i need to plug in internet + miner for the light to be green all the time? Should it not light? I don't find it on my router when having it powered + internet connected.

TYVM!

BTW sorry but
Part 4: Setting up the controller
Sucks...

I think GAW miners offer $185 including shipping.
