and -- is Minera using vh's CGminer fork that provides the needed driver?

[strada001]

Are you plugging the miners directly into the Pi's USB ports, or are you using a separate powered hub?

Have you considered the amount of power the sticks draw?

I'm using a USB 2.0 powered hub (it gets 5v 2amps in) I have no clue how much power they draw.

[NotFuzzyWarm]

ref 1st few pages of this thread. Power charts are there somewhere.

Being very honest, I don't know.
I downloaded Minera from their website and I believe it's the most recent version of it, no mods done to it by me.

the youtube video I followed was this one:

Any help will be more than welcome.

[NotFuzzyWarm]

Well for a start, ask in the Minera Software Thread about it. Probably have to load vh's version and have Minera call it as an external miner of sort so the custom driver is used.

[strada001]

A RPi3 does not provide enough power to USB for a 2PAC. Get a Powered Hub.

Where can I get a good/great one??
open to suggestions.

Amazon/Ebay links are welcome

Or search around, because there are entire threads here dedicated to discussing the best hubs for these.

I did yesterday and I found one.... 2 min later my 3yr old reseted my computer and now I can't find the damm thread.

Thank you so much.

This is exactly the one I was on before the reset.

I have try without and it stopped mining after few minutes, I just used a powered USB hub and everything is fine now,
(no additional parameters regarding the frequency), 10.5gH in average

thank for share this information. I'm looking for some usb hub

Possibly running into an EXTRONANCE subscription problem with combination of:- CGminer + Nicehash + 2PAC

Hello all,
This is a noob question mostly directed at "philipma1957" ...however, anyone else is more than welcome to comment.
Philipma1957, on page 11, post #213 (of this thread), you mentioned that you were running CGminer + Nicehash + a couple of 2PACs, etc.

This is pretty-much everything I'm desperately trying to achieve - however I seem to be running into a problem with correctly configuring my CGminer .bat file with the inclusion of the "xnsub" extronance suffix in the URL.
ie. Ive tried many variations of the .bat command line, however I eventually settled on this:-
"cgminer.exe -o stratum+tcp://sha256.eu.nicehash.com:3334#xnsub -u 3JgCy49LatQgGiZj4qc1s5mJ6ynCUNdNgq.WORKER-NAME:worker1 -p x"
However, running this reports the following error when I start CGminer:- "Failed to resolve (?wrong URL)"

Strangely enough, when I change the above line to add the "/" before the "#xnsu" suffix (as per Nicehash's, "BFGminer" .bat config recommendation), CGminer then starts reporting that it has successfully connected to the Nicehash pool - in addition to this, my 2PAC starts flashing away merrily as if its making me a fortune (at 10-14Gh/S) and Nicehash reports one worker is active ...but no stats become available and bitcoins are never accumulated/given (as they do when running my vastly inferior GPU setup) .

FYI, I am running the latest pre-compiled (.exe) version of CGMiner for Windows (v4.10.0), which I downloaded from the first page of this thread.

In summary, would it be possible for someone who is successfully running the combination of CGminer + Nicehash + 2PAC, to copy/paste their .bat file command line - which I can then at least try.
...or failing that, I'd even be willing to settle for some REALLY SIMPLE, "noob" advice


PS. Ive also just started dabbling with setting up a local stratum server (to hopefully circumvent the #xnsub (extronance) problem)  ...but so far, even though I've managed to successfully launch it and see it report a stable connection to the Nicehash pool - I have not been able to get my CGminer/2PAC to run/link through it.

[philipma1957]

waste of time you simply don't need it

EXTRONANCE  on a tiny little miner  may not ever work correctly .

you are renting your miner on nice hash.

so some  one get point it to any  pool that does sha 256.

look at this post

https://bitcointalk.org/index.php?topic=559011.msg21692224#msg21692224

and the post after it.

your 2 sticks are only 22-32gh

so any time you switch(since you are renting  the renter does the switch not you) to a pool  with  64 gh diff and back to a pool with 8 gh diff

you get conflicts with nicehash min diff number of 65gh

so what happens you could freeze or crash I now point my sticks to mmpool and hop for a lucky hit.

What coding do I use to use these through CGminer?

[Will0C]

Many thanks Philip ...what you say makes perfect sense and even explains some of the other little symptoms/problems which I never got around to mentioning in my post

[gregho]

Can anyone help with with a stable way to use gekko 2pak in minera I'm not too good with coding and I've tried a few things and can't seem to figure it out any help or direction would be helpful and if any of you could tell me how to run it that would be great

[sidehack]

Have you tried the search function? Minera has been covered at least three times already, and once in the last week.

Checkout Biodom's post https://bitcointalk.org/index.php?topic=1764803.msg17678108#msg17678108 on where to measure the voltage.

You can use one of these guys to measure power-draw



Search ebay/aliexpress for "usb voltmeter amperemeter/ammeter"

Edit: Forgot to mention, vcore of about 1.5V should get you close or slightly above 300Mhz but you'll need proper cooling, that's for sure. These guys get very hot.

Speaking of which, does anyone have a particular meter or seller they would recommend, with the case and screen similar the picture above?

I just looked and there are about 500 available on eBay running from about $0.01 to about $20. I don't mind paying a little extra for quality or a bell or a whistle, but that price range presents a lot of options.

EDIT: While I'm asking, any recommendations for a decent multimeter as well? Billions to choose from.

Thanks!

You know, I was out, really out, and then my dang nephew badgered me into learnding him this stuff, and so, here I am. Again. However, I am very glad that he is interested in something like this!

[gregho]

So what I see is this

cd /var/www/minera/minera-bin/src

mkdir -p git/vthoang; cd git/vthoang

git clone https://github.com/vthoang/cgminer.git

cd cgminer

CFLAGS="-O2" ./autogen.sh --enable-gekko

make -j 2

cp cgminer /var/www/minera/minera-bin/custom/cgminer-vthoang

cd /var/www/minera/minera-bin/custom

Which is what I used initially BUT SOMEONE SAID TO ADD this line of code

cp cgminer /var/www/minera/minera-bin/custom/cgminer-gekko



But where does this last line of code go when I enter it into the terminal in miner it says no is there a special way to enter it?
