GekkoScience 2Pac/Compac BM1384 Stickminer Official Support Thread

[vh]

4.9.2 = incorrect software for 2pac.
drop minera and use the instruction on the first post so you can sort things out on the pi and its peripherals.

Maybe your hub sucks.

Hello I found the issue.

I set --gekko-2pac-freq 150 and I guess the sticks can't handle it, so when I set it to --gekko-2pac-freq 50 it started hashing.

What freq is the stick suppose to run on?

[sidehack]

Stock is 100MHz. Stock voltage should be good for 150-175MHz but note they pull 4W at 100MHz so more like 6-7W at higher speeds. If your hub can't handle more than 1A to a port you'll have trouble. If you're plugging the stick directly into a Pi's port it definitely can't handle it.

I just did --gekko-2pac-freq 100 and it went to 0 hashes.

 The max it can go is --gekko-2pac-freq 80 as far I get

Yep, your hub sucks.

Yep, your hub sucks.

Forgot to mention that I am directly connected to the raspberry pi.

If you're plugging the stick directly into a Pi's port it definitely can't handle it.

I'm saying I directly put it in my raspberry pi and its only able to handle 80, anything higher makes it do 0 hashes.

[sidehack]

Right, and I'm saying that's entirely expected because the Pi's ports are current-limited and the whole thing's being sourced from a weak-sauce micro jack. Page one, post 10:

Might I suggest adding a note for Raspberry Pi users that is is EXTREMELY HIGHLY suggested to use a powered hub and not the Pi's USB ports directly....  They have trouble even supplying enough current to a portable USB self-powered HDD... let alone a stickminer =)   I don't want to see people with unnecessary troubles related to this =)

Hi, folks
Yes I am a newbie mining excited with a GPU in my beaten up Pavilion.  It's been so fun to hear coin dropping sound whenever my lazy digging accepted as "prof of works".  So here I am joined the forum for mother of layman's asic revolution; Gekkoscience from Sidehack, Great works!

I got all the plan laid out to seriously mud myself and the first challenge is to get Gekko 2PACs to start and here is what I took from reading the board:

"2Pac sticks are $30 apiece for any quantity. For the sake of simplicity, I'll charge a flat $10 on shipping for all US orders. If you're interested in purchasing, PM me here or email sales@gekkoscience.com with quantity, shipping address and desired payment method."

This was posted 2016 and I wonder if it is still correct.
If it is not, can anyone guide me to submit order of small quantity US shipping?

I didn't want to bother Sidehack directly for he must be one of the busiest person on earth these days.
Thanks to all in advance.

Hello,

Despite days of trying, I can't seem to get my Raspberry Pi to recognize the 2Pac I have installed.  It is on a powered USB hub, and there's just one of them.  I have followed the instructions on Page 1 of this valuable thread to the letter, and at least part of my problem is that cgminer does not enable the gekko despiter the --enable-gekko command in the ./autogen.sh step.  Here's what I get:

Maybe if you PM sidehack and get on the list for "seconds" sticks, but as of right now I am not aware of any place to get them for anywhere near the original price. There is a link to the thread where he talks about the seconds in his sig block if I remember correctly.

at least part of my problem is that cgminer does not enable the gekko despiter the --enable-gekko command in the ./autogen.sh step.

did you at any time install any USB to serial drivers? For example for Moonlander 2 (Silicon Labs?). Are you using or previously used any other USB ASICs on your workstation? I got this error on my mac after I installed Silicon Labs for my scrypt Moonlander 2 USB ASIC. Couldn't use Gekko 2Pac and jstefano Moonlander 2 on the same workstation at the same time unfortunately. May be possible, but I haven't looked into it much.

Verified you can not have Moonlander installed on Mac and run Gekko CGMiner under the Mac OS. That said, i am running Parallels with windows running the 2pacs and the host OSX running Moonlanders. No problems at all. Cheaper than buying a new machine. You can just tell Parallels which devices to autodetect and which to leave to the Mac. I have 6 of each running no problem. The 2pacs are at 200 with a fan. Get a zombie or two a day - have the hub setup on a wemo plug so can just restart it remotely as Windows isn't nearly as elegant in handling devices, hence the restart. When I run running the 2Pacs under OSX natively, CGMiner would automatically restart a zombie after a few minutes. No such luck with Windows unless I am missing something. There was about 10 hours of my life I will never get back trying to figure out why the 2Pacs wouldn't run after Moonlander install. $49 is pretty cheap fix (I already have a Windows VM) though.

Wanted to see if this worked on a stock rpi3, it did not on stock.  For the benefit of the unfamiliar and those who dont readme README's.

From a completely fresh Rpi install I needed to

Code:

sudo apt-get update
sudo apt-get install autoconf libusb-1.0-0-dev libcurl4-openssl-dev libncurses5-dev libusb-1.0-0-dev libudev-dev
sudo make install
sudo usermod -G plugdev -a `pi`
sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot

then just run cgminer.  I use a conf file so my command was

Code:

cgminer -c cgminer.conf

You can also use the command line if you like typing long strings of shit over and over

The above sequence worked perfectly on a stock pi 3 with the current (Raspbian Stretch) image file.  

Just FYI for the googlers later

the example was specifically for dinofire to compare difference in his autogen.sh output
working raspberry pi instructions are on the first post.

Hello,
I´m just trying to overclock my two 2Pacs a little more. I´m using one (instead of two) sticks on one 30 W hub. So the power supply shouldn´t be the bottleneck any more.
Now I´m working on the cooling. Does it make sense to buy another heat sink? Maybe like this one?
http://www.ntodesignsinc.com/product/gekkoscience-2pac-rev2-heat-sink/
Is copper a better material here? I´m still using the arctic breeze fan. I went up to 350 MHz now and you can still touch the heatsink with your fingers without getting burned. I´m just wondering if a new heatsink would be enough for now or if I have to exchange the fan into a more powerful one.

I own 3 2-pacs and I'm having trouble getting them all to work at the same time. I have a Saberent HB-U14P usb hub. They all work fine individually, but when plugged into the hub, only 1 or 2 will work at the same time and the other turns zombie. Re-inserting means the other 2 will be disabled and only the re-inserted one will be hashing. Any tips?

Most consumer-grade USB hubs have voltage and current limiting built in.  When you plug in more than one 2-Pac miner, it becomes the active one and zombies the others.  To use more than one 2-Pac in the same hub requires closer attention to the hub's specs.  I would say you need a hub that will output (permit) at least 1 amp per port.  2+ amps per port would be better if you want higher than stock hash rates.

the documentation for your hub states:

"For a stable connection, the devices connected to the 13 Port hub must not exceed a combined current of 5 volt 2.5A. Each USB port on our 13 Port hub will only provide 5 volts 300 Milliamps. "


You need more power.

hello everyone.

I just registered to ask my own question. I am having an issue with one of my ASIC miners. 2PAC BM1384 USB Stick Miner.

I have 2 of them. one is working great and currently on a pool hashing away.

the other one has been giving me a headache.

down to the point. i installed the USB drivers using zadig. both were detected. both drivers installed. one USB is working. the other isnt getting detected by cgminer. i did some self troubleshooting like using a different machine with the one that is working. It works fine on the other machine. the one thats causing an issue doesnt work on either machine.

one machine is windows 8.1. the other is windows server 2012 R2. (dont judge, i plan on going to linux once im comfortable enough with how these things work.)

any idea onto why cgminer isn't detecting the USB? is it possible that its a defect? I hope not. it took a month to get here. it shows both USB sticks installed with no errors in device manager.

any ideas or suggestions?

thanks.
