Right - and in order to setup the miners - need wallet address.  Don't want to have edit config's later

so no wallet password yet to get this setup nor source code to get it setup on my own server... gee kind of hard to mine without a wallet or the soure

I've hacked apart 2 BFL single power supplies - mainly because they both blew up...

If you cut the PCI-e cord between the round part and where it connects to the brick unit - you will find 4 wires.  Both of mine were different.  One was nice and easy - 2 reds and 2 blacks.  The other - it was 4 different colored wires.  You could then connect these wires directly to the Ant S1 using the screw terminal connections.  To be safer - connect one BFL brick to each side of the S1.  In theory you have enough power - each side of the s1 takes about 200 watts. 

Since my BFL supplies blew up - I used just the PCI-e end of the cables to wire them up with wirenuts to some 14awg wire and sent that to a dell 750 server powersupply

I've picked up 7 of these boards - and I have to say - I'm dumb founded.  Most of these 750 supplies can consistently pull 800 to 850 from the wall and not even blink.  Sure they are loud when you turn the fan up, but the screw terminals mean infinite wiring options for any type of device whether it is PCI-e or not.  Just wanted to say - I'm thrilled with them.

Off Topic - did you find the heat sinks actually helped?

I'd be up for 2 - perhaps more depending on price - time frame, etc.

If the S2's come down in price - i'd consider one of those.

so are there enough other p2pool servers out there that it is still similar to mining in a larger pool like btcguild?

Pardon the noob question -- for mining BTC - is it still connecting with other P2Pool servers?  Or is it waiting to find a block solo?

If the BTC is still mined as part of a bigger collection - then this sounds like a great idea - run your own pool so you can have very low latency (i.e. a server by the miners) - and then the BTC stuff is still merged in.  I've happen to already have old server hardware sitting around anyway that can be reformatted.  Granted they have tiny drives - so I'd need to find something bigger to actually store the block chain.

I setup Cgminer following the directions from Kanos - http://www.kano-kun.net/?p=87

Then I did this

That then moved all of the chainminer files into a new folder - so I could move them back if i needed to

Then


Then

cd to the cgminer directory (/opt/cgminer for me)



I'd make it sure was all running - then press Ctrl+a then D (that tells it to disattach from the screen) -- screen allows stuff to stay running on linux after you end your SSH session.


Once you get everything working -- check the crontab that was default in the image -- Don't bother doing this till you are done tweaking.


see the command about killing the screen -- and it references a file something like /etc/local/rc.d  -- I'm writing this from memory

Open up that file      then you can edit which command it is running - by default it will be trying to run a command to open up chainminer and the stratum proxy.  You can replace this with the command you need to run cgminer.

Hope that helps -- mine still aren't stable - nor are they performing very well - and I'm having to reboot cgminer every 20 minutes to get much out of them other than a metric ton of hardware errors.

Let's say one has several 20A circuits, could you load balance and wire together several of these - spread across multiple circuits?

Also when you load balance the 3 - per the picture - can you put another wire on the 12V terminal that is being shared - ie can you still have 4 PCIe leads out of each board? 

I had an old router sitting around - so I just used it as an ant setup router

good call - worth a shot at this point.  

I'm also thinking setting up the pi to kill cgminer and restart it every hour or something.

I've been using difficulty 256 - anyone have better or worse experience with others?

My blue boards all have pins down - and 2 of the green ones.  I had to hook them up to the pins down on the controller.  The pins that were down on the controller appeared to have been added after - or the pins that were up were.  Either way - it looked like someone soldered the pins on themselves.

Rocket Box is 450 Ghash at 480watt.  RX-Box is 2400 Ghash at 1.2w/ghash

The pictures are the same.  Is an RX-Box just 4 Rocket Boxes over clocked?  or are the boards bigger with more chips?

I'll post some pictures later - finally got 18 boards hooked up - in 4 chains.  HW error rate seems high.

Went to a computer recycler and bought some server fans that push 100CFM from an 80MM fan - stacked three high on the one side - the output was so powerful the fans blew themselves away from the cards - so I had to rig them  up with zip ties.

Ended up using a pack of these B00GWF65GK (well it was similar) and 2 packs of some that were 26 or 28mm  from amazon.  Then i grabbed some small plastic ones to use as spacers.

This thing isn't pretty by any means.

It is drawing power from a Dell server PSU with breakout board from Minersource - the Barrel connector adapaters are getting warm - so I plan on running new wires with the 2 screw adapaters from amazon straight to the dell PSU.  For 12 boards Kill-a-watt says about 475 watts from the wall. 

I couldn't get chainminer to work for a darn - so I ended up the cgminer route. 

Several chips still get too hot - or are just bad - cause cgminer tries to increase their rate and then drops it later on.
 BaB0: chip 59 disabled!
 [2014-06-11 00:16:11] BaB0: Chip 106 BAD - speed down from 52 to 51
 [2014-06-11 00:16:12] BaB0: Chip 122 High errors 94.30% - speed down 52 to 51
 

I tried this - and the boards that i removed the fans from - seem now to get way too hot.  I pointed 4 120mm case fans at the bank of 5 boards to see if it helps

You can order standoffs from some of the dx and aliexpress type sites - or several sellers on amazon have them.  search for 3mm standoff or something like that and pick the ones you want.

I've gotten about 11 boards up and running anywhere between 400 - 500 ghash on cgminer.

I'm going to play around with some reconfiguring of the stand offs - as suggested by helipotte.  As well as try to reduce the number of boards per chain. 

I'm not sure what was meant by the back feeding on pin 10  so I likely won't be doing that.

It's clear that one of my first mishaps was to connect boards with the pins down and boards with the pins up - as well as then not worrying about whether the pins were up or down on the controller card.

Got some of the boards working - the ones with the pins facing down - hooked to the controller with pins facing down.  Couldn't get chainminer to work for a darn - so I'm using cgminer for now.  More HW errors than I'd like but I'm hoping that can be configured away.

I have 11 of the 18 boards hooked up now.  Based on space, power and the lack of standoffs - I have to get some more parts in to get the rest working

my Rpi had a version of Scripta on it - so I just downloaded the image file in the first post on this thread and went from there. 

Mine aren't working yet - so perhaps my solution wasn't correct.  I just hooked up the cables so the arrow pointed to the side that had 1 on it.  I couldn't figure out any other way to do it
