GekkoScience 2Pac/Compac BM1384 Stickminer Official Support Thread

[swanny88]

Did one of these 2Pac sticks ever find a block?  I know the odds are crazy high but just curious.

Doubt it, theoretically possible, but really they are toys. Impossible to keep them running continously.

what makes you say that?

i was thinking of setting them to restart every 12hrs or so. i think that should keep them going

[marousi]

how to set them to restart every 12 hours? please explain

[zac123]

Well I saw a post by a guy that set a cron job like a scheduled task basically that did the restart.  I think he had his rig running on a rasbery pi

For Windows, I use AutoHotkey to make/run a script that will close and restart cgminer on a timed basis. You can use a smart plug to hard-reset your hub.

cron job is the way to go for linux/RasPi.

Hi thanks for the reply.
Yes trying them on their own was the first thing I did. Black one is stable green one not.

Try turning the voltage pot to 3 o´clock with the USB port at bottom and view on the pot. Then set the frequency to 100 MHz. Then set the frequency to 175 or 200 MHz. If there are HW errors coming in, turn the pot clockwise until they stop coming in. Maybe you have set the pot too high already.

I think moste of the people here, me included, have got them running continously. So I won´t say it´s impossible. My oppinion is, it wasn´t even hard. Mine are running for weeks without any issues. Only the PI freezes occasionally. But even that happened once or twice in the last months.

Ok, running continuously at say 250 mhz? or higher? My setup is 6 2pacs, 2 2pacs/powered usb hub running at 200 mhz. holding the 2pac with the usb port down, the screw is set to 5 Oclock. They do not run continously. Don't know why?

Hi,

sorry if answered before, i was used search and not find answer. In other hands I don't read 90 pages, only 3 first (sorry guys).

I have 2 similar setups:

* raspberry pi
* sipolar usb hub
* 2 gekkoscience 2pac

The main difference is one setup has 2pac US (GSD) and the other one have EU (BSD).
I was installed with 2 month of difference. The US ones first and 2 or 3 months after EU setup.

I have a problem that cgminer shows different in EU. It's more log rather than US is like "window".

And the EU:

The question is, how could I switch between this to views? In some cases I need to work with the first one, in other moments I need the second one with log format.

I'm running the same command in two cases, for me is a mystery why in one rpi are showing in log format.

Thanks

Like I wrote a few times before, I have two 2Pacs. Each one in a 30 W Hub. Both running at 350 MHz. Voltage pot is set about 6 or 7 o´clock. Each one cooled with a Arctic Breeze fan. Both controlled by one RPi with cgminer.

Can you post the cgminer.conf file you are using? Does it have the --text-only option? Or do you start with this option? The option -t is the same? Do you use this one?

I'm not using conf file and neither --text-only

Only executing command:

Code:

sudo ./cgminer -o stratum+tcp://pool.ckpool.org:3333 -u btcaddress -p xxx --suggest-diff 32 --gekko-2pac-freq 225

Thanks

May be worth checking the display option (D).  One may have verbose (V) turned on.  Hard to tell from the photos.

You were missing a dependency while compiling, I think curses but I could be wrong. Make sure you have all the dependency packages per the first post instructions and re-compile.

thanks for your help on this.

currently have the pots pointing towards 5 o'clock running at 250htz. i get about 24hrs until they need restarting with ~9 hardwre faults.

still tweeking. my aim is to have them running @ 300 stable. we'll see. but its good fun getting it all work. the long term plan it to have 5 of these running on a ras-pi in a little cooled box that i'm designing so it can sit on my desk at work :-)

Are you still running one at a time? Are you able to run one alone at 200 MHz at 3 o´clock? I think that 3 Amps isn´t enough for 250 MHz to run stable.
What happens after 24 hours? Do they go zombie?

In my experience putting them into a box isn´t the best solution. I tried this, even with an open case and two fans. They get hotter than with my current setup, open just inside the hub with the arctic breeze fans.

yes i think you are correct about the usb hub.

ok so what i'm testing now is this:

• BSD 10014358
• 3 o'clock position
• 200 freq

i'll next be able to check it about 17:00hrs UK time. that's approx 28hrs time

OK. Then let me know if it worked.

Thanks, I was followed Ubuntu instructions instead of Debian. I was installed missing dependencies, recompiled and it's working.

ok good news.... its been mining since my last post at 200hertz, 3 0'clock position. it is showing 15 hardware errors.

so, should the next test be to up the hertz on this one or test the other stick at 200 .... hmm.
