got them running great on a debian 7 build .  19 sticks .

@Jake36 thanks for help on the cgminer install



 I will post a shot later. -------- shot below

This was the first linux build I ever did.  I burned a boot cd  took a few hours to set up I

still have some quirks , but those are my quirks.  Since I never did this os before.

 I have good numbers for the sticks

19 on 2 hubs  freq 125  

Mighty impressive.
AND
Congrats on your first Linux build.

Most build Linux 4-6 times the first time, there are just SOOOOOO many options cuz' Linux is so configurable.
What distro did ya' start with?
ALL our servers run Centos 6, which may not be optimum for what your doing.

So far I have used Debian and Raspbian both have worked good for me.  I like them a lot better then messing with windows drivers.

I think we will see more going linux with compac's.  Just is a heck of a lot nicer in my opinion then messing around with windows on them.

In my experience, USB connections are noticeably more reliable (though still get flaky occasionally) on LINUX machines.

 Slackware in my case, been using it since shortly after Yggdrasil "apparently" died (Yggdrasil eventually put out ONE more version of their distribution, about 2ish years after I'd already switched, THEN died).

i have done extensive testing of various USB scrypt and SHA256 miners and always had trouble under windows once i went to linux i never went back all my rigs are now running on various custom Pi Linux miners found here on the forums

yeah seeing linux in action reminds me of when max os worked nicely say 10.6 or earlier.

I know apple uses unix/linux alot after 5 minute or so I can see the closeness.

I think linux will be my go to os.  I just need the time to work on it.

Just throwing this out there, but it looks like we're only a block or two away from getting the first payout from Eligius on the 1BURGER. It's pretty small (about ten bucks) but the significant thing is that payout was mined entirely with hardware I built. Some of it was sticks being tested before being shipped (and our burn-in is at most three days - if it's a weekend - not three months like those other guys) but a lot of it was test hardware and prototypes.

Pretty exciting stuff.

1BURGER will buy 2 Burgers.

Is the pick-and-place all dialed in now?

[sidehack]

It's pretty close. Most of the problems I have now are related to the stencil and solder paste. The stencil needed to be a bit thinner, I think, because I'm getting too much solder on some of the QFP pads especially on the CP2102 and it's bridging. I also need a smaller belly pad area on the BM1384 because it's giving too much floatation and about half the time I have unconnected pads. The stencil guys asked us about shrinking the belly pads and were going to make that change but apparently pushed through the design as it was instead. Whoops.
Part of the problem is the solder paste is too dry, since it sat in the box at room temperature for two days before being delivered and lost a lot of its binder. It doesn't spread on the stencil worth a hoot, gums things up instead of transferring cleanly.

The pick-and-place is pretty well calibrated, but occasionally has trouble with the peelers. Every now and then it'll bind up and not peel, so it spools out half a dozen parts without picking any up and then stops with an error. Sometimes it skips a hole on larger parts and isn't aligned right, same problem and stops with an error. Of course there's no audible signal that it's stopped, so I just have to come back and check on it every now and then and see if it's still working.

huh

am I the only windows person with no problems point and click results?

yes I like the command line but my wife can run windows. I have ubuntu installed as the only OS on many old laptops. I like it but windows is everywhere, and nix is not
all I can say is my MANY windows rigs run fine 24/7. my freenas box runs fine too and there a good reason to run it.

my house has a personal house only 24/7 HTPC based web server with easyphp lookup WAMP dont laugh   please my cards are windows only and it works well. I wouldnt trust my personal install on the real web though

[sidehack]

I've never mined successfully on my Win7 machine with anything requiring Zadig. I test Compacs coming off the line with a stock cgminer 4.9.2 on an old XP32 laptop, zero problems. I've run Habanero, Prisma and New R-Box off the same laptop without much trouble. My old GPU rig was Windows.

In our shop, there are two Linux computers and one BSD machine for every Windows box (that isn't a crappy test laptop).

[SlimePuppy]

My Win 7/64 box is running two sticks beautifully.  The only snags were probably senior moments - forgetting to reboot after installing the Zadig driver, forgetting to put zlib1.dll in the cgminer directory, and forgetting to run cgminer in an administrator/elevated command window.  One thing I did notice is that I have to stay with the USB2 ports on this Asus P8P67 mobo - a stick at a 150 MHz clock would only run about 4.5 Gh/s and about 75 WU/m in a USB3 port while the same stick in a USB2 port runs about 8.2 Gh/s and 115 WU/m.

The RaspPi 2 is running edonkey's Minera package (thanks!) smoothly, though my current powered hub can only handle three sticks at 150 MHz.  The new hub comes today and (hopefully) all the sticks will move to the Pi.  Then I'll spend some 'quality time' turning the clocks up a notch or three.

And yeah buddy - those LEDs are bright!

Dammit sidehack - I managed to miss the 'stick phase' first time around...you had to do this, didn't you?  LOL

[sidehack]

I missed the stick phase too, mostly because I was getting bigger stuff instead. I had some Block Erupters that I pushed to 16.4MHz, but after that I didn't have another stick until I was given a U1 or we started collecting for the museum.

I'm hoping we can get chips and work on bigger stuff, but folks are having so much fun with this that we might try to make a second Compac with a bit better features if we can ever get a decent chip. This stick took a lot more work to get together than it should have (I burned nigh a month on the first iteration of the buck circuit before giving up), but the groundwork's already laid now so tweaking the existing design for upgrades shouldn't take long at all.

We're still ironing out ideas for a pod miner, but between Bitmain not selling us chips (neither old nor new) and the guys I've talked to telling me the price is too high, it seems unlikely to happen.

I wonder how many people would be willing to sell dead S5 boards for about $10 a pop? I'm thinking on an 8x BM1384 pod (since we can't get better chips) but chip cost would be way too high and also I don't have enough anyway. If I could get a bunch of dead S5 boards and pull chips, it wouldn't be great but it'd knock down the price quite a bit.

[chiguireitor]

Received the sticks today! Yay!

Testing them on Win 7/8/10 and working like a charm with zadig, no errors whatsoever.

Trying to get them running on my ubuntu server, but couldn't get it working as i needed to get out of the office early for some medical checkups.

Nice piece of hardware, congrats on the stick sidehack/novak.

That is all! no "buts"

I'll give you two i was going to thrash, you pay shipping or give me some kind of way ship them paid, i want nothing in return, i won't ever ask for any thing either. unless i pay for it  . one other time in a PM I asked if you wanted them "). it's cool if you don't, I'll thrash them .

[sidehack]

Ah, yeah I know I've had one or two people asked in the last few months if I wanted dead boards. Re-message me and we'll work out the details.

*NIX is more common than you think.

 Pretty much every router "appliance" runs some form of LINUX (Cisco is the only major exception, they have their own propriatary OS stuff).

 Most of the Internet runs on some sort of *NIX - the exceptions are mostly (again!) Cisco boxes in the bigger routers.

 Many older smartphones run on a *NIX of some sort, though propriatary seems to be making a comeback lately with Android getting popular.

 Do keep in mind that the Mac OS is *NIX under the hood.

 To get technical, Windows "borrowed" a LOT of *NIX design concepts in the NT series and it's later derivations, and somewhat to a lesser degree MS-DOS and consumer Windows versions did as well. MS-DOS also borrowed heavily from the older DEC RT-11 OS though (both RT-11 and UNIX borrowed from older OSs as well).

When you say you could not get it working on linux what part are you getting stuck at?   If you post what your having trouble with we might be able to help.

Early Cisco IOS's were heavily based on Linux.
When NT was released NT had dynamic memory allocation/deallocation, Linux did not.
To me DOS stole more from CP/M & MP/M than the PDP 11 OS.
Much of the NT design team was "lured" away from DEC, so it makes sense that NT has "under the hood" similarities to RT-11.

Core Dumped Blues

Well, my terminal's locked up, and I ain't got any mail,
And I can't recall the last time that my program didn't fail;
I've got stacks in my structs, I've got views in my queues,
I've got them : Segmentation violation -- Core dumped blues.

If you think that it's nice that you get what you C,
Then go : illogical statement with your whole family,
'Cause the Supreme Court ain't the only place with : Bus error views.
I've got them : Segmentation violation -- Core dumped blues.

On a PDP-11, life should be a breeze,
But with VAXen in the house even magnetic tapes would freeze.
Now you might think that unlike VAXen I'd know who I abuse,
I've got them : Segmentation violation -- Core dumped blues.
