Do you know of any hubs that keep all the ports on a single level? I already purchased and installed a 2nd RaspPi and have 20 miners on each, but in the future it might be helpful for others that want to control more from a single unit (which I bet it can since 20 miners only results in around 10% utilization).
Probably too expensive but here is a 49 port designed for continuous enterprise use: How about 2 of these?: http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=6436&seq=1&format=2 One for each of the Raspberry Pi's 2 ports? We should be able to conceivably connect up to 48 miners per RPi... Anyone had any experience with these or know its internal topology? Or you could try two of these? I don't like the port layout though: http://www.microcenter.com/product/393329/28-Port_MondoHub_SuperSpeed_USB_30_HubThe one from monoprice looks nicer. Yeah, and a bit spendy (could get 2 monoprice ones for price of 1 MondoHub), plus I could have sworn i've read in one of the many threads floating around that the gridseed miners don't play well with USB 3.0 devices. Unfortunately the price on the hubs is roughly the same as a RPI so there is little incentive to not just run 2x 10-port cheap hubs per Pi and scale accordingly. -Eric |

Thanks, I will start working on a raspberry pi setup later this evening. Most of the setup guides I have read say 10 miners with a pi. Any tried a pi with say 40 miners?
It is doable, but you need to connect USB hubs in a certain way. You can only have 2 levels of hubs with the Pi, and 10-port hubs than come with the miners already have 2 levels inside them (6+4 ports typically). So you would lose 4 available ports if you daisy-chain those, and you need to connect to the correct ports on the first hub. Use "lsusb -t" to see the USB structure. AHA!!!! That explains it then! I have 40 miners and when I attached the 4 10-port hubs to a 7-port powered and then to the RaspPi it would only recognize 32 miners (10+10+6+6). If I connected 3 hubs it would only see 26 (10+10+6). So i'm guessing it was able to see a maximum of "levels" and after the first 2 10-port hubs are attached it only sees the first level of any additional hubs.

Delion19,
I'll shoot you an email and we can coordinate directly on a time to resolve this. The easiest option would be if you want to purchase the smallest increment (an hour), i'll credit you an extra 45 mins at the full 13MH if that sounds good to you (45 mins to balance things out since the hourly rate is higher than the best price rate).

I either expect a full refund or compensation for the time and money lost from mining with your rig. If no response within 24 hours, I will leave negative trust score
Was that hashrate reported on the leaserig website or your pool? For whatever reason on some pools the LeaseRig proxy will only display the hashrate from one node instead of the aggregate and displays as anywhere from 3-7MH. I'm replacing the last of the original controllers with Rasperry Pi's running cgminer today so this should no longer be an issue! Please let me know how you would like to be compensated if this wasn't simply a display error. -Eric |

Have you considered running it as a service? Would certainly clean things up if you actually want to continue using that computer while mining! (not to mention you don't have to worry about when the computer crashes and/or reboots while you're away).  |

Thought i'd post some pictures of my "Ducted" low profile setup that is in progress. I have a low table in my work area with about 6" of space underneath it and I thought I would design a rectangular enclosure that maximized airflow via a wind tunnel design while minimizing noise (I removed 80% of the fans).
Here is the first quadrant put into place. Note the units still mounting fans are slightly recessed in for noise mitigation and after checking airflow I realized that 4 fans per quadrant was overkill and reduced it to only 2(visible in later pics):
Here it is with the second quadrant filled:
I'm now ready to start setting up the rear quadrants and have positioned the miners with fans at the front of each stack. The overall airflow with the lid on is actually pretty decent.
Here is the view from the "front" or intake. The overall dimensions are 36" L x 20" W x 5" H and the ducts for the miners that run down the centerline are 12" in length.
There are currently 40 miners running and I will be working to clean up the wiring a bit more with zip ties. There are 8 cables that come out each end (6 power and 2 ethernet) and are plugged into power strips which are then connected to a 500watt UPS (single mode mining only!). The ethernet cables plug into a 4 port wireless bridge which connects back to my gateway router in the living room.
Hope you guys enjoy the pics and it sparks some ideas of your own!
-Eric
P.S. Total cost for materials was about $40
How did you disassemble the fans? Just cut the wires, or....? Yes I ended up just cutting them at the edge of the heatsink. That leaves about 1.5" of wire trailing from each end. If I really needed to re-attach I feel confident I could splice it back together (though I hope I never have to!). All said and done it was around 6 hours of work to unbox, wire everything, fabricate the enclosure and do initial setup. Long day, but interesting! And things definitely went faster by the time I got to the 3rd and 4th LA3M |

Can anyone comment on using Raspberry Pi vs. the Controller?
Can the RasPi vary the Mhz up to 900?
Does the RasPi get the same hashing rate for the same speed?
Can it run the miners without rebooting (or rebooting only one miner when the miner disconnects)?
Any other advantages or disadvantage of the RasPi vs the controller?
I've got 10 running off my RasPi: 1. Yes, you can vary it using the --freq=900 flag for minerd. 2. Yes, in fact I'm seeing a slightly higher rate, but that could just be because of the improved stability. 3. Yes, running rock solid for 3 days straight now with no reboots, freezes, etc. I won't switch back to the controller unless they do something amazing with that firmware. I like the concept, but i'm curious how well it can scale with a more sizable amount of miners. Would a RasPi be able to support dozens of units? I've heard the controllers that ship with the units can technically support up to 20 units, but they are underpowered and the hashing increase tapers off as you add miners (sorry I don't have the source for that report). -Moomjean |

djeZo,
So, if i'm understanding this correctly, the applet essentially works as a stratum server that your miner is pointed to which is then uplinked to the leaserig website?
If so, this sounds great since I will be receiving a bunch of gridseed miners tomorrow and I was scratching my head how to get them to work with Leaserig. Now i'll just run the applet from my HTPC and point all the miners to it's IP as my pool address.
Just read the Readme and it sounds like this might be the solution I was looking for! Now I just gotta sit here refreshing delivery details and wait for DHL to arrive....

I've been following your posts and you only said you'll match the lowest competitor price. Which I think your $225 per 60 is certainly in line with. I don't begrudge you your markup, but hey everybody is always looking for a deal... If my 40 units weren't already sitting in customs in LA waiting to be delivered tomorrow I would have definitely bought from you and saved myself over a grand. *shrug* I'll let these start working down their ROI and maybe get in on the next group buy in a month or two (especially if any new hardware is developed). -Eric |

Jack reported that another 20 boxes were shipped a couple hours ago and low and behold after calling DHL I now have a tracking #!!! For those of you anxiously waiting, its time for the daily 1800 CALL DHL, tracking check. I wish you the best of luck and i'll post my mining rig setup once I fabricate everything over the weekend. -Eric P.S. on a side note, if your order was shipped today, according to DHL it was picked up late so they can't guarantee Friday delivery to the US and it might not arrive until Monday  |

Just as a side note lads, it took 12 days from payment to delivery I never got tracking info from Jack it came via TEXT message direct from DHL.
Hope this helps.
You got lucky. After 2 weeks, I just got a tracking number and it will ship tomorrow. u didnt sent jacl all details needed, so stop whining. send all info requested Lack of details is definitely not the issue. I paid back on the 10th and submitted all info. Angela contacted me on the 19th asking for my "tel no and postal code" which I responded with in 5 minutes. Since then my daily routine for the past 6 days has been: 1. Call DHL to see if package has been shipped using my name and zip code (and they tell me no) 2. Contact Jack via Skype and re-explain the situation to him after which he says he'll look into it and msg me back (I provide all my contact info again including tel no and postal code). 3. Hours later I attempt to contact him to make sure things have been straightened out and he usually says it'll be shipped that day and he'll send me the tracking # asap. 4. No contact or response until the following morning. 5. Goto step 1. 5a. Every other day I also send Angela an email with the requested info in a futile hope someone/anyone will pull their head out of their ass. I can understand them not being able to initially ship my package 6 days ago when they asked for my ph # and zip code, but WTF has been going on since then? |

Order on the 9th and paid via BTC on the 10th (payment confirmed that day). Last message I received was yesterday morning asking for my phone # so they could send me the tracking #. Unfortunately I called DHL a couple minutes ago and they ran through the same check as the poster above with my zip and name but couldnt find any package that has been given to them for shipping yet. Leaving for the weekend so I guess i'll wait until Monday to begin really worrying, but definitely frustrated on the lost hashing opportunity over a long 4 day weekend (especially since orders much later than mine have been shipped and received already)... |

Hmm, 2 Erics on the list... Hope i'm one of them, though I have yet to receive a tracking # (but I did get a payment confirmation email back on the 10th when I paid via BTC).
Flying home tomorrow and I sure hope there is a box waiting for me! (I even got a bit antsy did a preliminary manual keyspace check on the possible tracking #'s and randomly came across a shipment to Arizona and one to Germany for "LA3M" according to the manifest!). Yeah I know, I gotta go find something more productive to do while i'm waiting...

Beastlymac (or anyone who has these in hand), can you tell me if the unit is only being run in Scrypt mode does it still need the power adapter or can it run entirely off the USB connector?
I've got a bizarre idea on how to mount these using 4" PVC tubing that i'll cut a slit down the side of for cable and reset access. Each tube will be a stack of miners working in their own little wind tunnel. I may even remove the fans from the individual units and just mount a single inlet/exhaust fan at each end since i've heard they generate very little heat.
I'm hoping each stack of 10 with the majority of fans removed would fit into a 24" tube and be quiet enough to keep in the living room near the network access point.
Any thoughts or better ideas?

To the people with units, can you tell me what the diameter is for these units? Thinking of ways to build a case for these suckers
I found the specs and they're 95mm diameter and 70mm tall, so roughly 3.75" D x 2.75" H. I've been looking at stackable mesh racks similar to this: http://www.amazon.com/Fox-Run-Stackable-10-Inch-14-Inch/dp/B000QIZ1AU/ You can fit 6 miners per level and just point a box fan at them if you want additional cooling. Perhaps not the prettiest, but would do the job, is compact and best of all, is cheap... |

Just ordered several... fingers crossed on the scheduled delivery date since i'm leaving with the pregnant wife for a "Baby-Moon" around the time its scheduled to arrive... I'm also really hoping those 500kh per module numbers actually pan out!  |

All feedback welcome!
SteadyHash is now ASIC based and is running on 40 Gridseed miners! Currently hashing at 14.5MH (billed at 14.25)!
Any previous speed issues have been resolved (been going over a week without a single downtime or fluctuation in hashing power besides normal dips from pool switches) and speed is now guaranteed with a 2x compensation for any discrepancy!
