Did anybody see this already...?

I received three more gridseeds from Zoomhash for a total of 9. All are working without any problems at 330-350. I used my own 360W power supply that I got from ebay for $28.

Received 10 gridseeds within 4 days from Hong Kong and 1 gridseed in 2 days from Zoomhash directly.

During testing, had 6 gridseeds fail; 2 sparked when I connected to my desktop computer directly without USB hub and 4 others wouldn't register using the USB hub that came with the units. The original USB hub was pretty cheap (open motherboard design, but I think ZoomHash is going to start sending out better quality USB hubs in the future).

Mailed in 6 bad units and received replacements within 2 days from the time Zoomhash received the bad units.

Discovered recommended solution to connect all gridseeds:
Be sure to test each griseed individually!!! After all are tested can connect all at once.
1. Purchase quality USB hub (unless Zoomhash sends you one) The Rosewill 10 port USB Hub http://www.amazon.com/Rosewill-10-Port-High-Speed-RHB-500/dp/B004F38WT4/ref=sr_1_1?ie=UTF8&qid=1396692212&sr=8-1&keywords=rosewill+10+port+hub has been tested by others with 10 gridseeds connected. I purchased 2 Hubs and am very happy with them (running for 4 days straight now with 5 units).
2. Use a quality power strip and turn it OFF (POWER IS OFF)
3. Plug Gridseeds into power bricks (I have 2 x 12V 10A bricks with 5 connectors each) and plug power bricks into power strip (POWER IS OFF)
4. Plug USB Hub into Power Strip (POWER IS OFF)
5. Plug Gridseeds into USB Hub (POWER IS OFF)
6. Plug Rasberry Pi into USB Hub and Power Strip (POWER IS OFF) - Assuming the Rasberry Pi alredy has the OS loaded and tested
7. Turn ON Power at the power strip so everything powers on at once.
8. By the time RasberryPi OS loads it's close to a minute. It recognizes all gridseeds start hashing
*** If you are going to unplug or plug in anything, turn the power off at the power strip first!!!

The Rasberry Pi software Zoomhash puts out is actually not bad, and if you are noob that doesn't konw linux it's downright sweet.  http://zoomhash.com/pages/raspberry-pi-corrupted-mining-image
Once the image is loaded and you boot it all you need to know is:
user: pi
pass: zoomhash
pi@rasberrypi~$ ./minerconfig.sh (this will prompt you to enter the pool you are connecting to, # of gridseeds, and Herts to run)
pi@rasberrypi~$ sudo screen -ls (this will display each gridseed as a number ####.#)
pi@rasberrypi~$ sudo screen -r #####.# (this will display the status of the individual gridseed)
pi@rasberrypi~$ CTRL + A + D (this will release the screen and bring you back to the prompt)
That's it!!! so simple and auto hashes on reboot!  Now if they only could include scrypta they would have an awesome setup.

I have tried most other distros and they can be a real pain to enable SSH, install applications, configure applications, then it doesn't auto-start and have to set that up too.

Called tech support a number of times and they were super firendly and very helpful. Cannot recommend ZoomHash highly enough. I will admit they were slow to respond via e-mail, but a phone call and trying different connections till I found a human let me speak with very friendly and helpful associates.

340-345 is more realistic so you should be at  6.8 or 6.9

Finally got mine a couple days ago!  All 20 hashing away with Zoomhash Pi.  At 850 MHz, almost no HW errors.  However, I'm expecting around 7.2 MH, but Scryptguild says I'm getting around 6.2 MH.  It's been hashing for 48 hours.

Using cgminer gave me more insight about the individual units, and t looks like GSD 16 has a bad core (if I am reading it right).  The right columns indicates solved blocks I think.  If that's the case, only 4 of the cores are finding blocks.  With so many GSDs connected, I don't know which one is GSD 16.  If I can pin point the bad unit, I'd like to RMA it.  Sure it's not much lost when compared to 20 units, but when I am ready to resell them they will most likely be bought individually.  1/5 dead is not very good.

Even with a dead core, I don't know why there is a 1 MH/s discrepancy.  At 360 kh/s each, a dead core is only worth 72 kh/s.  Any ideas?

Yep...the bricks are real piece of sh.t...Mine blew up on a first power up...Fzzz...Gone...

miaviator has been awesome helping me.

now using a psu which is working great!

damn bricks blew my office fuses!!

running my 18 miner.  I have an issue with one of them it seems to get much lower hashrate then the other 17 grids ..

 1 hour run time

1)372.59 Kh/s
2)332.15 Kh/s
3)332.15 Kh/s
4)337.45 Kh/s
5)358.29 Kh/s
6)334.34 Kh/s

7)280.03 Kh/s

8)340.47 Kh/s
9)358.95 Kh/s
10)346.29 Kh/s
11)342.23 Kh/s
12)339.01 Kh/s
13)366.60 Kh/s
14)345.70 Kh/s
15)350.11 Kh/s
16)345.73 Kh/s
17)368.80 Kh/s
18)347.19 Kh/s

So I am good at troubleshooting. I have not bothered to start doing that as I spent some time getting the 18 units 2 at a time 4 or 5 a week for about 1 month.

 but here is a simple question lets say no matter what i do it runs at 265-290   do I get to return it?

just curious about the WU within CGminer. Getting 361 kh/s  (which is fine) but the WU is 1-2/m...in past for scrypt with GPU it always should be 90%= of your hashrate..and that is always what you're truly paid on and actually hashing out..so is this just different due to the type of miner? or should it be higher..i believe it is being read correct online via the pool..but want to be sure..
thanks

Don't try and power the GS with the bad bricks. I did that and lost them. ZH can be a tad slow to respond, they were having issues with their email. They should be in contact soon if they haven't already.

both power bricks dont work - what do I do? sent an email but no response.

would be nice for you and him to do a deal.  it is a good product I get 350kh a unit in scrypt only and it pulls under 10 watts.

2 of these = 1 hd7970  and that pulls more then 200 watts vs 18 or so for 2 of these.

Hey Zoomhash im in LA want to meetup and discuss some group buy options for my buyers?

BAMT won't work because it's for PCs, the RPi uses an entirely different processor, not PC compatible.

I've been using the HashRa Controla image modified by DarkKnight. Here's the thread on litecointalk : https://litecointalk.org/index.php?topic=18096.0

Mining SHA256 and scrypt coins in dual mode works right out of the box with the HashRa Controla image. A little bummed that in dual mode, it only reports the SHA256 hashrate. You have to check your scrypt hashrate at the pool. But maybe somebody fixes that soon.

I haven't tried Scripta, maybe I'll give it a try sometime if I'm curious. Last I checked (a couple days ago) it didn't do dual mode, but maybe you don't care about that.

Define competitive?

Price competitive vs DOA rate vs Actually Shipping vs Correct order rate vs payment flexibility

what are you actually looking for?

i too purchased a 10 set and got it fast, but the price has already been reduced? does that mean they are not competitive anymore?

I just wanted to thank this community for all of the information provided which assisted greatly in
determining what to buy, where to buy, configurations, etc. etc.

I opted to purchase from ZoomHash and am very pleased with every aspect of their operation. Just sharing my experience since I found what others' have passed along was very helpful to me.

-> I placed a credit card order via their website on 3/26 and got an e-mail confirmation within minutes
    (8:30AM). (Small order: Single Gridseed & Power Block)
-> At 12:37 the same day (3/26) I got an e-mail indicating the order had shipped along with a USPS
    tracking number.
-> On 3/28 I got an e-mail indicating the order was on its way to its destination.
-> 3/29 : Will it make it today (Saturday)?. Probably not. Checked the USPS Tracking number:
    "Departed USPS Sort Facility" about 4 hours away. Spent Sunday regretting I hadn't ordered
     a day earlier.
-> On 3/31 the item was delivered. True to their word: Priority Mail 3-Day.

When I arrived home, I found there to be a *SLIGHT* problem. I ordered:

(1) 12v 7amp Power Adapter for 1 Gridseed Asic                       
(1) GRIDSEED 320 ~ 420 KH/S ASIC SCRYPT & SHA MINER

Instead of the 12v 7amp Power Adapter, I received a 12v to 6 Pin PCI-E PSU Molex Gridseed Adapter which is currently listed for $7.50 USD. As it turns out, this configuration (using the PCI-E to Molex Power Adapter instead of the12v/7amp Power Block) worked out better for me; with the exception of the $10.49 cost difference between the two items.

One e-mail later and less than a day later, this small problem was resolved to my satisfaction and my second order (#2879) with ZoomHash has been placed with, no doubt, more to follow.

Yes the Pi's can handle up to 32 so i have heard it runs my 10 perfectly, but i would sack off the zoomhash image. It uses CPUminer and one session per gridseed unit, So if you have a problem with one you have to connect to each screen / cpu session at a time, it makes it very awkward plus it does not register the hash rate correctly, you can only measure it from the pool.

I built my image from scratch and put cgminer 3.7.2 with scripta on it. It works beautifully. So now all my gridseeds are monitored from one screen / cgminer session or from the scripta web front end. Plus if i want to change the pool remotely i just need to edit my daemon for cgminer and restart the miner and its changed. Where as the zoomhash image you have to run through that crap script and restart the pi its not ideal.

Hi ZH/Michael,

I just put in a smaller order (Order ID is: #2832) for two 20 packs to keep things simple.  I put in a note to ship the same way as before from China.  Hope you can see to it that your shipper sees the instructions.

I will be in Hongkong the end of this month and maybe I can pick up more when I'm there.

Same here, Ordered 5 and some accessories late late Thursday night, delivered and up and running by Monday afternoon. Nice job ZoomHash.
