GekkoScience Compac BM1384 Stickminer Official Support Thread

Long or short wires? Heavy or thin wires? Capacitor bypass for high current nearby? Providing the same information a third time is, oddly enough, not nearly as helpful as providing new information.

you think a usb cable is better than 1 meter of 2mm² for the power ?
have you a new stickminer projct ?

[Cc2Gre]

i like your work !
but today :the  BM1387 is very impressive
bitman work hard and fast...
i dream you create a new board for us
i know it s a dream... lol

[sidehack]

I think a USB jack on a board with nice beefy power rails and a big capacitor close by, such as you would find on a hub, is better than 1 meter of pretty much any wire. Especially when you're asking it to feed current to a switching regulator. Long wires carry inductance, and inductance opposes current changes; switching regulators have really rapid input current changes. Long wires carry resistance, and resistance means voltage drops at high currets, which mean your regulator could be bottoming out and turning off.

I'm pretty sure this has been covered in the thread already. I know you're not a native English speaker, so I'll try and be nice, but I also get kinda annoyed easily.

[Cc2Gre]

sorry but i love our product/work and the principle.
i think i will order one of your green version in usa and another one on bitshopper to compare them...
sorry but i don't see your answer for your(s) eventual futur project for usb miner...
sorry again but read many hundred pages during several days in English while i m french...
i stop boring you

[sidehack]

If you have asked me a question and I didn't answer it, and then you asked four more times and I still didn't answer it, that's either because I can't answer it or I won't answer it. I figured you'd realize that at some point.

So, my advice for helping solve the problem - if you're going to use long wires from a lab supply, drop a large capacitor (probably at least 220uF, maybe 470-1000) across the 5V and GND pins on the USB plug at the end of the wires you're hooking the stick into. Keep the input voltage below 5.5V; adjust the potentiometer for about 660mV and try a 200MHz clock. If that works, try 700mV and 250MHz, then 740mV and 300MHz. If nothing works, the stick is probably bad (but I won't point fingers) so contact the manufacturer for assistance.

[Cc2Gre]

ok

[w0mp]

I finally got it working with the latest bfgminer.  Anyone having issues with it dispaying the right hashrate?  Mine says "86/48/15 Gh/s" and I am at 150 MHz clock

EDIT:
nm, jsut restarted computer and replugged gekko stick, shows 9-10 gh now

Just received my GekkoScience Compac from bitshopper.de  (https://www.bitshopper.de/shop/sha-256-miner/usb-miner-bitcoin/compac/)

I have an existing Minera setup which works well so I thought I would try the cgminer-gekko image posted in this thread.

However whenever I plugin the USB Miner I get the following:

Which is great but it's followed by:

Jul 17 09:38:20 moria kernel: [  523.046271] cp210x 1-1.4:1.0: device disconnected

I have tried various boot command options to no avail:
slub_debug=FP
dwc_otg.speed=1
usbcore.old_scheme_first=Y

I've also updated the firmware of the PI, updated all of the software packages and updated minera to v0.7.0

Anyone else have the same setup and had this problem?

How would you go about getting a stick repaired? Have two of them and one just stopped working on me. They were overclocked(300Mhz) but with proper ventilation/cooling(front and above). Have tried numerous configs(Win 7 and PI/Minera), adj voltage and freq, hub/no hub and still cant get it working. Other stick works on all configs. Purchased from holybitcoin on 5/26/16

Thanks

[sidehack]

Step one is talk to holybitcoin

What version of the Pi are you using and are the sticks at stock settings?

i never got minera on the rpi b to work with my compacs.. probably user error and i didnt mess with it  to be honest.  i just disabled minera and compiled straight from the source for the gekko version of cgminer.

upshot is I just didnt use minera, i compiled the gekko version of cgminer on the pi and ran it from a terminal.

[vapourminer]

btw the 4 compacs on the rpi have run several months non stop perfectly. they (pi/hub/compacs/switch/modem/router) are all on ups, so that helps too; crappy power here.

the 5th, compiled on ubuntu 15.10 runs fine for weeks at a stretch but that rig is not on a ups so it drops dead when power glitches otherwise im sure it would run non stop also.

[drew_ii]

vapourminer, or any other pi-heads out there, I searched the forum here and elsewhere and can't find an answer.

On my either 2B or 3b (I'm pretty sure 3B) I run two copies of cgminer concurrently - one runs 4 sticks at 425, and the other runs three sticks at about 350 or 375, whatever I can get them cranked to.

POWER for the pi comes from an unpowered (port on-off switchable) hub connected to a powered 2.0 hub, as does the on board pi port go to the powered 2.0 hub.  THe 2.0 uplinks to 2xSuperbpag 3.0 running sticks in alternate slots, staggered for maximum airflow, with four fans going on.  Two fans are run from the *2.0* hub, and the other two from the secondary 3.0 hub (where the three slower sticks sit).

Here's the issue:

If I run both simultaneously, I can almost always count on loss of network connectivity within 24 hours.  I can restore it by unplugging and replugging the network cable, and there's some talk of ifup/ifdown commands to refresh the DHCP lease, or setting the IP static.  I Also added eligius to the hosts file to see if that helped, but it didn't.  I lose the ability to talk to eligius and im down until I notice it.

HOWEVER - if I just run the 4 sticks at 425 its rock solid for days. (the other three are plugged into their superbpag but the hardware refresh is 0'd out or they are zombied on my active cgminer)

Any ideas?

Thanks,

drupie

very cool and interesting idea there

[Mikestang]

I like the little fan mount, cool idea.  You could probably even get 2 of them on there and then cover the entire heat sink.  Do you have a laser thermometer?  Would be interesting to see what the temp difference is on the heat sink beneath the fan and on the sides.

[drew_ii]

Thoughts about soldering the power leads direct to the +5v/Grnd leads of the USB connector instead of running it off of another port through another cable?

Drupie

[gt_addict]

Someone has already soldered a barrel plug to the 5v and gnd for additional power delivery. Its further back in this thread I think, or try the gecko run thread on the main page.
