:-\Unless I am totally missing sumtin which may be possible, but from my experience this "Custom Antminer s7 Firmware" Doesn't Work At All.
It appears to just be a bloated non-functioning Antminer S7 batch 1 firmware copy.  It even has the "ping 114.114.114.114" line in /etc/init.d/cgminer.sh NOT commented out. Since currently (well at last time checked) this ip address is down and has been for a week or longer Cgminer will not run.  Also when I went to check the version of Cgminer after running on the SD Card that "new firmware" was dd'd to it was still showing 4.8.  I contacted Ziwalla (or how ever the spell it) Support and no response, not even an automated response.  So it's either one of a few things possible going on here:

1. Totally Doesn't Work At All
2. Does not Run on My Batch
3. Terrible Customer Service / Non-existence Support

 
Has anyone actually gotten this "Custom S7 Firmware" to Run ?

I am probably just going to Extract Original Batch 1 Firmware
to a virtual linux box and fix the cgminer.sh file
And then possible update/upgrade system
Install new version of cgminer and
Then recompress to flashable tar or just make a img file to
write to Sd Card boot.  
These were really the only features i was interested in if anyone has already done this and would like to share
That would be helpful otherwise if anyone else wants when i'm done i can post it up here or new thread for people
to freely download and use...


  

OMG U ROCK!!! Worked like a charm!
(I actually just changed the 114.114.114.114 ip address to my routers address)
Again Thank you...

On a separate note has anyone found where you can enable/disable the S7/S5+ Controller boards Data port? It would be nice to either upgrade firmware and enable more than 3 data ports...

I just hooked two units together via the rails and then unmounted both control boards and place a single bb board and data port board in between the two miners held in place with  a little velcro.  The original cables the S7 ships with are plenty long enough when set up this way...

philipma1957,

 Which data ports are your hash boards plugged into? can you take a pic?
I am having issues plugging 6 boards into one S7 Controller where some ports don't seem to
recognize the S7 boards correctly and don't hash.  I am seeing this on batch 1 and batch 3.
Does anyone else who has tried plugging multiple S7 systems into on controller seen this issue?

 

 

Heya don 't know if you're still looking for an answer on this but your best bet is to get a cheap SBC and use it to run your UltraHoist board you will then have te ability to tweak the voltage setting.  Newegg was selling the Cubieboards for $19.00 (not sure if sale is still on).  Cubieboard1 is not the best but BitCrane does have an official linux image for the cubieboard as well as a pretty slick web interface and keep alive scripts for you UltraHoist board.  You can also get a pcdunio for $15.00 to $20.00 on ebay but would need to configure any linux image you use for mining purposes. I attached the the SBC to the bottom of a metal plate that the hardware store had on sale then mounted the UltraHoist board on top. This worked fairly well in creating an independent mining unit that can hash around 550GHs to 850GHs depending on how hard you push the board and the metal mounting plate helped draw heat from the UltraHoist Chip...

What ever you do don't buy used miner from 2ndHandMiner.com

This is the shadiest site ever. I want to warn and recommend everyone not to buy any hardware from Amy K Brannan and their website.  I purchased an S5 Antminer and it arrived with only one hashing board working.  I tried to work with Amy to get the issue resolved and my return request was declined, also I was told that they called their representative at Bitmain Tech and told them not to honor any warranty repair for my item.  Also they have a tendency to jack up the price on a product once you add it to your cart. So if it's like 499 and you add to cart to check out all of sudden it's now 599. They are super shady and not customer service friendly at all.  It takes them at least a week or two to respond to any issues you may have. Don't trust these guys and don't order from them they won't make it right and they will send you malfunctioning equipment.

I have a number of PSU from EVGA and have done some testing with powering 2 S5 Antminers from on PSU.  I found that the 80 Plus Gold EVGA 1300 Watt SuperNova does an excellent job powering two miners with fans on front and back of both.  Also the 1300 watt is fairly quiet and does not seem heat up too much.  I have found that the 1600 watt 80 Plus Platinum is a bit overkill and could probably power 3 Antminer S5's, but seems to get excessively hot just powering two.  While the EVGA 1600 watt 80 Plus Titanium runs two Antminer S5's and stays super cool and in ecco mode doesn't even need to power up the fan to stay cool.  What I found very interesting was that the older generation EVGA NEX 1500 Classified watt rated at 80 Plus Gold gave me about 15% to 20% more hashing performance.  The NEX Classified did run a little hotter than the Supernova 1300 watt but not as hot as the 1600 watt Platinum.  Also the dip switches allow you to power up without sticking a paperclip in the mb cable (something that always made me a little uneasy).  Also you can change it to single rails from 8 independent ones and with 220v overclock the psu to 1650 watts.  I don't know if the 20% boost in hashing power makes up for the slight inefficiency in power conversion but for me i always like to see faster hash rates.  Has anyone else seen other PSUs that seem to provide you a boost in hash rates?   

I thought I read some where that when switched on the controller board will flash morse code of the NiC's Ip. I believe this is enabled on the T-110(s) ans would have also possible worked for you.

My buddy is letting me use/making me fix his Miner T-110. At frst the issue was that the web controller would stop giving access to the control pane/plane, So i attempted to simply update the syste, kernal, and packages.  Now he controller board does not see the usb mining cards at all and "lsusb" is giving errors about noy being able to display or load devices.  I think it would take long long time to go thru and figure wherre it all went so wrong and the best option is to just reimage the flash drive with the stock shipped SD Image.  Does any one know where i can snag it or can you send a copy of a clean working Image for the BitCrane T-110.  I have a few email in at support forBitCrane but have bot heard back yet. 

Heya also great overview the system Dogie if i get thus working and my buddy wants it back i probably gonna get a few. I like the Idea of stacking three but would they operate as a one worker cluster or just as three independent workers...

Again thank for any help on T-110 System Image.
