Wow,   I got it working!

Thanks so much you guys!!   

Any recommendations for pools and currencies for this?   I'm going after Litecoin in www.Multipool.us right now.

  Good job!  Next lesson, read up on which coins you can mine with a GekkoScience 2Pac BM1384 Stickminer

https://www.coinwarz.com/miningprofitability/sha-256

 You might as well lotto mine on ck's solo pool.  It is possible but not probable that you will mine a block but you will make mere pennies per day per stick if you have zero energy costs.

 The probability of finding a valid block with each hash

It seems like all the pools I'm adding to Minero are dead pools?

Hello

I'm having kernel panics with Minera 0.8.1, two GekkoScience 2Pac and a Raspberry Pi Zero. I've followed the setup from "http://www.badbox.de/2017/07/cgminer-for-asic-usb-stickminer-on-raspberry/" and have gotten them mining (lights flashing and interface reporting GH/s) anywhere from 10 seconds to 12 hours i get a long kernel panic.

http://i65.tinypic.com/21lsr3c.jpg

I have a USB hub with 25A of power, plenty of cooling that works fine with 2 miners at 100-400mhz on a windows system. I have tried 2 Pi Zero 1.3 and a Pi Zero W. The Zero W seems to always crash shortly after mining starts. I have tried 5 different USB hubs all powered by 2A or more PSUs. I've tried a manual install of minera. lastly I've tried 4 different SD cards.

I was also wondering if there is a compatible version of bfgminer that works with the 2Pac.

You can't mine most alt-coins with this. It only mines SHA-256. That means for the most part Bitcoin, Bitcoin Cash, Namecoin, Peercoin, that sort of thing.

It will not mine other algorithms. There was a link posted above that has a list of coins you can mine, but Monero and Litecoin are NOT mineable.

I'm interested in mining coins like monera (spelling?), ZCash, Dash, Litecoin.

Any pools that I can use with my Pac2 that you know of? 

General tips/thoughts about mining coins other than bitcoin with the USB ? 

Some pools like SlushPool won't work with CGMiner?      I'm using Kano pool now, but the GUI isn't very pleasant to look at.

Thanks again for your tips guys!!   

I am going to compose a document:   GekkoScience Setup for Dummies and post a link here.     Given what I just went through, spent 20 hours on, I think I'm in a unique position to help other ultra-newbiees.

 Pete.  I replied to you a couple of posts ago and gave a link to the only coins you could mine with SHA256 ie your Gekko 2Pac.
Why don't you look at it before you compose your Setup for Dummies document?

I've not posted a lot here, but I've been mining with the asic erupter for 2-3 years off & on.  I think I have ~$4.00  duh... needed to keep it running.  LOL

I have been using cgminer with ASIC erupter 333mhz miners, pointed to slushpool.  bfgminer is easier to use, since you do not have to compile for each driver. I consider that a real pain.  I have these directly connected to Raspberry Pi, v.3b, v.2b, v.B+. The B+ only runs 1 miner, the other 2 run 2 each.  I have them connected to a multi port 60w USB power supply.

To stay on thread, I'm working on a 2pac single unit on my Pi 3b tonight.  I hope it works.  I've gotten one or two to run a short run on the 10 port usb 2.0 hub.  Then they zombi, real annoying.

I'm frustrated, finding the proper USB 2.0 powered hub, that folks use.   Thank you for reading.  JLH

I am sorry if I'm posting too much in the thread.   But for the benefit of others in the same situation.  Could somebody help provide the code for Minera in Raspberry Pi?    

Minera has a dedicated terminal for entering code, including GekkoScience Pac2.  

This guy's code didn't work for me (fyi)
https://www.youtube.com/watch?v=UQndxAfk-hM&t=557s

His code (THAT DIDN"T WORK - don't try this)
(in Minera Terminal one line at a time followed by return/enter key when prompted)

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



Somebody in the old GekkoScience Compac BM1384 thread compiled Raspberry Pi3 code that would setup Gekkoscience AND Minera.   I think that could be a super helpful tool.    Obviously I am asking for GekkoScience for Dummies type information here, which isn't too far from the truth.

Once again, I'm sorry if I'm talking too much here.   But I'll ask in case it helps people.      

I have used the code above, i've had one issue.  I can not get cgminer to write cgminer.conf.  It crashes.  I have to dig & see if it is a permissions issue, I love to blast 777 on files and folders. Smiley

If you have any tips, please let me know.  Thank you

Use the search function. It's a known issue with cgminer core.

The USB commands menu in cgminer will let you list all devices (press the L key) and hitting S and entering the ID (zero if you have only one stick) will show the device settings and stats. At present the temperature is always reported as 0, and a casual visual inspection doesn't show anythign that appears to be a thermistor. Unless the BT chip itself reports temperature, an external thermometer is your best best, because either the hardware doesn't report temperature, or cgminer as yet doesn't have instructions for querying the temperature sensor.

The 2Pac will mine sha256 coins. The ASIC (the chip that does the hashing work) is specifically built for performing sha256 hashes. It will not do other work. xhomerx10 posted a link to a page listing the types of coins the 2Pac can mine: https://www.coinwarz.com/miningprofitability/sha-256

Alright so any coin based on sha256 can be mined right ? (Like all those in your link)

I'm frustrated, finding the proper USB 2.0 powered hub, that folks use.
Am I understanding correctly that you are looking for a working USB Hub?
I have a 30W 7 Port Hub from Aukey where I connected 2 2Pacs. But I bought it on amazon.de.
On amazon.com it woul be something like this:
https://www.amazon.com/Anker-7-Port-Adapter-Charging-iPhone/dp/B014ZQ07NE/ref=sr_1_2?ie=UTF8&qid=1508871680&sr=8-2&keywords=high+power+usb+hub
I think it doesn´t have to be USB 2.0. Mine is USB 3.0 as well and it works fine.

I'm not an expert, but it appears so. Searching for "cgminer" and the name of any coin in that list I've searched for so far has returned results and examples, and if you can mine it with vh's build of cgminer then you can mine it with a Gekkoscience 2Pac, simply by changing the pool URL in your cgminer command line.

I also bought a Pluggable 7-port 60W USB HUB on Amazon for $30 USD. I don't have three GekkoScience 2Pac yet, but that's the intent soon.

Lately, I'm running two on the USB HUB and I keep getting ZOMBIE on one of the sticks. It is not a specific stick, but one will usually ZOMBIE out while the other is working okay.

I currently have it running at 200 Mhz at 9.11 watts. It chugs along at 22 Gh/s and will just die. I tried giving more watts up to 10 W per stick, but that didn't help stability.

My next step is to try 150 Mhz and see if that is better. 150Mhz takes up about 8 watts per stick.

Any thoughts?

Are you keeping it cool? 9W per stick is pretty hot, and hotter than 200MHz should require.

How're you measuring the current consumption of each stick?
Can you measure the voltage across the capacitor for each ASIC chip?
Finally, do you have a fan on the heatsinks?

In the time I've been playing with a 2Pac, the only zombie events I've had were when the cooling wasn't sufficient. Trying for minimum heatsink fan speed mine ran happily all day but then zombied about 3 hours after the building's aircon shut down for the evening. Running exactly the same setup with a higher fan speed and it's just run happily overnight @ 325 MHz with ASIC voltage of 0.73V. I feel it's worth monitoring both heatsink temp and ASIC temp on the back side of the PCB to get a feel for how effective your heat transfer is. Playing with tightness of the heatsink screws will let you find the optimum clamp force for heat transfer. Too  tight and the PCB flexes and transfer is less good.
