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.

Well it completely stopped so I switched back to Ubuntu server on the Thinkpad for now.

Will try again over the weekend but if it hashes less and produces more errors it's gone. Just communicating my results so far.

This graph shows that it hashes slower and the point where it died (12PM) before I switched back to the Thinkpad.

 

Have seen up to 50mm standoffs available. Make sure you post pictures of your creations here! Would like to see what people come up with.

Hate to be posting this (especially on Pi day!) but here are my results of using the Pi with 17 miners.

Getting the Pi working was a breeze! Simply loading the OS (Raspian) and logging in through SSH (after the initial menu config) allowed me to compile cgminer just like on Ubuntu server....although a LOT slower.

After modifying the text file for stability (as posted in this thread) I fired up cgminer and it started hashing. Things were looking good and I was elated so I went to bed. I did notice that on the Pi cgminer takes from 10-25% CPU sometimes shooting up to 50%. Figured that was fine as long as the little guy was working.

Little backstory. Before using the Pi I was successfully mining using a ThinkPad laptop with Ubantu server. I took two screen shots in 24 hour intervals on that computer. First was at 800 and the second 850.

Back to the Pi...so I woke up and checked in on the Pi. Was disappointed to see some of the miners were not hashing as fast and that the average was low. HW was also MUCH higher.

Left it hashing and went to work.....checked on the pool to see how it did overnight...not good:



You can see where I started to use the Pi at around 2:00 AM. For some unknown reason it went WAY down from around 5ish to 8ish. Overall the hashrate looks lower than the Thinkpad.

Will keep it running on the Pi for another 7 hours but thinking that it will be going back to the store. I'm sure it beats using the controllers but perhaps it's just not fast enough.

Not that it matters for scrypt...but why do you have the miners bowing down? Those shelves do not restrict allow airflow blowing up. Would think that would be better especially for dual mining?

I've had 3 bad ones so far. When their good their oh so good....but when their bad 

Anyone try out the CuBox-i? Comes with Ubuntu (and android). Do you think I could compile from cgminer from github on it? It's ARM based like the Pi.

...but they were born to be free..not hidden in a cage!

Obtain some standoffs...then you could creatively make a pyramid or anything else your imagination can come up with  

Yes, angled power and USB may be needed. I'm sure Cablesz could whip up the angled power but anyone have a source on right and left angled USB?

Wow, I was just made aware of this thread otherwise I would have posted earlier.

I purchased 20 miners from their web site and picked them up in person last week (Tuesday I think). Unfortunately I did not get to meet Hash-Master himself but his warehouse staff were very friendly. We spoke shop for about an hour.

They are a legitimate business with (what appears to be) strong distribution relationships in China. I do not think they are very active on the board so it may be best to deal with them by phone or email.

+40 for me...see if you can get the price down to $120 each  

Don't need anything except for the miners themselves. Lets keep this simple and not deal with getting people power supplies, cables or any accessories.

Edit: I keep forgetting that the company I work for opened up a division in China a few years ago. We have frequent video conference calls and have already inquired if they could be a resource for sourcing product. If necessary we could have them deal directly with Gridseed on our behalf. They, of course, would require compensation for their time.

Or you could try two of these? I don't like the port layout though:

The one from monoprice looks nicer.

Also, this is the first gen product. There is talk of a 4-5U rack version coming out from Gridseed. Expect competitors to get off their butts and bring theirs to market too.

Looks like it might have been bitcoind. Restarted and have not seen it since.

Started to get this error message:

No bitcoind connection when block submittal attempted!

Anyone encounter this before? bitcoind appears to be functioning correctly and the p2pool node does not seem to have lost connection to it.

Probably too expensive but here is a 49 port designed for continuous enterprise use:

I have two Gridseed wiibox controllers available if anyone is interested.

Just the controllers. You will need a USB 2.0 A Male to Micro B (5-Pin) cable and wall plug to connect the wiibox to power. Most 5v 1A phone adaptors will work.

Paid $100 each so make me an offer.

Free USPS shipping.

Sorry if it is bad form to post this here...will delete if it is.

Thanks. Did not see the version without the ferrite core. Will order those to see if they fit better.

Edit: Just spoke to one of their reps using live chat. He said he compared both versions and they have the same size covers on the Mini-B side. Not sure if I should believe him or not.

Edit2: Went ahead and ordered 20 to see if they fit.
