Hello guys, I need some help as i just got started into bitcoin mining as a hobby (with a GekkoScience 2 Pac miner).

I had setup a Raspberry Pi 3 Model B, running the latest version of Minera based on the youtube guide https://www.youtube.com/watch?v=UQndxAfk-hM . The initial setup of Minera is fine, however Minera is unable to detect the miner and the hashing speed is 0. The miner is a steady bright white colour, and Minera log is as follows:

 [2017-08-22 17:22:43.522] Started cgminer 4.10.0
 [2017-08-22 17:22:43.523] Loaded configuration file /var/www/minera/conf/miner_conf.json

 [2017-08-22 17:26:47.850] Stratum from pool 0 detected new block at height 481616

Appreciate if someone could help, thanks!

Read the 1st post here...
The sticks require a driver that Minera does not have. You need CGminer with driver from vh.

Solid white light usually means there's a problem. Compile the proper cgminer as instructed in the 1st post and if it detects the device but doesn't mine with it, you might have to contact the seller for warranty replacement.

Any news on the pod miners?

Yeah, in the "news on pod miners" thread. This is the stickminer support thread.

You need to install the vh version of cgminer as a custom miner into Minera.

SSH into your Minera Pi, and follow the steps for  "Raspbian - Kernel version: 4.4 (Raspberry Pi)".

(edit: removed my extra steps based on feedback below.)

Once those are done, you should have a folder called cgminer.

In that folder, copy the cgminer binary to /var/www/minera/minera-bin/custom/

It'll then show up in Minera as a custom miner.

@sidehack

can you give a link to the "news on pod miners"?

also,  what is a pod?  I saw it mentioned on another thread.

Interestingly enough, the first search result for "pod" is this thread.

You need to install the vh version of cgminer as a custom miner into Minera.

SSH into your Minera Pi, and follow the steps for  "Raspbian - Kernel version: 4.4 (Raspberry Pi)".

I would add two more steps between the instructions to make sure you have your custom miner in the right place.

Quote
sudo apt-get install -y build-essential git libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev screen libtool automake pkg-config libjansson-dev

mkdir 2pac
cd 2pac

mkdir -p git/vthoang; cd git/vthoang

Once those are done, you should have a folder called cgminer under the 2pac folder you made.

In that folder, copy the cgminer binary to /var/www/minera/minera-bin/custom/

It'll then show up in Minera as a custom miner.

(Full instructions here for Adding custom miners: https://github.com/michelem09/minera/wiki/Local-miners)


your addition (as written now) would only confuse as your inserted syntax does not relate to what is below it in any way.

Sorry - maybe I'm rusty on my linux.

I was trying to create a subfolder for the user to add the cgminer they build into. I can edit out my change. (I see that I should've also made it so the checkout goes to the 2pac folder, but looking at my minera, its not an issue.)

I get is what you were helping with, just need to expand your writeup in comparison with what is in the OP, in my opinion.

Hi,

I followed the Minera 2pac tutorial https://www.youtube.com/watch?v=UQndxAfk-hM

But the 2pac won't be detected and light is white.

The steps I did in minera:
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

Did I miss anything?

Bye Moe

After all the statements above I set up the custom miner and selected the new added custom miner.

Do I also need this statement:

Quote
sudo apt-get install -y build-essential git libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev screen libtool automake pkg-config libjansson-dev

If yes, can I do this statement after all the other set up statements?

If your cgminer built, you likely have those libraries. However, that is the first part of the build - you need those before you can do the subsequent steps.

What's your minera log say when you use the custom cgminer? What are the parameters you're passing it? Does the cgminer you built work without minera?

Has anyone had any luck mining with these? I've been mining for 2-3 weeks on mmpool and haven't earned anything yet: http://mmpool.org/user/guttermonk

So I tried switching to mining BCC on suprnova for the last week and haven't gotten anything there either.

My miners are running on cgminer at 135MHz with no errors.

 You didn't switch them to BCH during the frenzy I guess?
The Bitcoin difficulty is far too high to earn much with these sticks.

time(to find a block in seconds) = difficulty * 2**32 / hashrate (I'll call it 16 GH/s)

time = 923233068449 * 2**32/16000000000

time = 247828489723 s

 if you mine on a pool that regularly finds blocks, your share would be based on this number so

12.5(coins) / time = 5.04381X10-11 bitcoins per second

 or 4.3579X10-6 per day

 or 0.00159 bitcoins per year per 2Pac

 You can check my math but it looks about right to me.  Really, you should run the 2Pac on a lottery type all-or-nothing pool like solo.ckpool.org - you mine using only your Bitcoin address as a username and when in the unlikely event you mine a block, you get all but 1% of the winnings!

 I've been playing for about a month, my best share is 32.5M difficulty but we're looking for 923B for the win...for the next 6 blocks at least and it is set to drop to 888B so our luck will improve shortly! Wink

Your math sounds about right. With 5 sticks running for two weeks on mmpool, my estimated round payout is .00030723 btc. At BTC's price right now ($4150), my 5 sticks would make roughly $33.15, and would pay for themselves in seven years. LOL ...I'll try solo mining and hope I win the lottery.

That's pretty much what they've always been for, learning tools and lottery tickets. I've never disguised the fact these will never pay for themselves - outside of the improbability of a solo block.
