Mining on Rapberry PI

[notlist3d]

No tax duty.
I ordered 4 more yesterday.

Paid 179$ shipping included.
Still better than bitshopper since they don't have any in stock anyway...

Custom miner go to /var/www/minera/minera.bin/custom (if you want to use them in minera UI)

The default cgminer is in /var/www/minera/minera.bin/ and doesn,t suport the sidehack sticks

With the 330Mhs you should use --icarus-options 115200:1:1

My 2 compac have been running at freq 210 with no problem for 24h (well ventilated too)

If you look at the compac thread there is a custom minera image that is already to use with compac's.  It has the compac-cgminer set up on it.  Just put image on SD and its ready.

Or you can use a more standard OS on the RPI and put compac-cgminer on it.  Its not that hard and really is good software.

I know, that's where I got the miner binaries and the compilation process

I'm swapping miners on my raspberry pi regularly so I like have several mining SW option

Hello

I ordered 4 more yesterday.

I hope there will still some left when i place my next order . The first order beeing just a test.

With the 330Mhs you should use --icarus-options 115200:1:1

Thanks. I didn't forget to specify --enable-icarus to create the binary file, but had no idea of
the options i have to specify when launching cgminer. What does this option suppose to do?

Btw which pool did you decide to join?

Have fun with your miners

That's the "COM" port speed and distribution of shares/block per miner.

Below is the information I got from someone else, credit to him.

--icarus-options 115200:x:x


x= 1, 2, 4, or 8 (only valid options, any other numbers will cause cgminer to fail)

115200 baud rate
x is work distributions

when used in connections with
--usb :y to override BU command line of --usb :1

2 miners --usb :2 setting --icarus-options 115200:2:2
will allow both miners to work on same work unit from pool
splitting work unit between both units

miner 0 will scan work unit from 0 to 7FFFFFFF
miner 1 will scan work unit from 80000000 to FFFFFFFF
patterns.

4 miners and the work unit is split between all 4
8 miners and the work unit is split between all 8

by allowing the work unit to be split between different number of miners the scanning process of the work unit will be shorter
8 miners working in parallel each miner will only have to scan the work unit
with 1/8th of the 0 to FFFFFFFF pattern
each work unit producing the max number of 8 byte results/accepted.

I'm using bitminter so far, maybe I'll change if I care to look for better options :p

Hello,

Thanks for your message.

With the 330Mhs you should use --icarus-options 115200:1:1

Here what i got:

pi@raspberrypi ~ $ cd /home/pi/Desktop/cgminer-gekko
pi@raspberrypi ~/Desktop/cgminer-gekko $ ./cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u Jeff_59.worker1 --icarus-options 115200:1:1
 [2015-11-02 09:10:14.284] ./cgminer: --icarus-options: unrecognized option                   
pi@raspberrypi ~/Desktop/cgminer-gekko $

Although it worked fine with the "official" cgminer v.4.9.1

I'm puzzled because i think i compiled the gekko cgminer with the option --enable-icarus --enable-gekko

Regards,

Jeff.

cgminer gekko only supports the compac sticks:

--enable-gekko --enable-icarus : gekko was built by gutting icarus and rebuilding for compac's, so to use icarus, you would need to do 2 cgminers. 1 for the cgminer-gekko, 1 regular cgminer for icarus, and run both cgminers 1 for compac and 1 for icarus.

Hello,

I'm using a Belkin F4U018-BLK with a 2.5A power supply

Do you plan to plug the 6 (4+2) gekko compacs on this HUB?

As far as i'm concerned, i ordered the D-link HUB:
http://www.amazon.fr/D-Link-DUB-H7-ports-pour-Noir/dp/B0000B0DL7

I will test and report its ability to support the compacs. Do you think that
pluging HUB on HUB to support more compacs is a good idea?

Cheers,

Jeff.

Ok, thanks for the information

I just have a question while we're at this topic any way. I also have a Raspberry pi B+ which I don't currently use as I was planing to create a CCTV using it which will be connected to a twitter account. but what I wanted to ask instead is that -- can I mine altcoins using this Raspberry Pi?

As a miner mining with a CPU no not really not much.  It does make a great controller though for some miners.   Avalon 4.1, U3, Compacs, pretty much usb miners or a miner designed to use it.  

As far as CPU mining not really worth it.  It is not much on mining machine but great contoller.

I will use the dub h7 too for the 6 compac sticks

My current hub ports layout doesn't allow that many sticks.

Daisy chaining hub doesn't work well or at all.
I've seen it covered somewhere.

Maybe in the "which usb hub..." thread ?

Found it:

Raspberry PI resources
As Aajo mentioned in one of the replies: don't forget, not all hubs work with raspberry pi, more specifically, USB 3.0 hubs will not work. Also RPi will not support hubs, which are nested more than 1 level deep. In other words, a hub with miners, connected to a hub, connected to RPi is OK, but not anything deeper. That was my experience.
Additionally, there seems to be a limit of 49 BEs that one Pi can control at once.

So 1 hub with multiple hubs connected to it should work

Rpi -> hub -> hub -> miner: ok
Rpi -> hub -> hub ->hub -> miner: not ok

If you use non-powered 2.0 hubs seems to be best working for me. I can throw a cheap hub on it and run U3's or something.   But some need power like when I run compacs, so the RPI is more picky on those.

But you are right avoid 3.0 for the hub.  It kinda all depends on what your task is.  For example another hot controller is the R1 I am using a 2.0 cheap unpowered hub and works great.

Hi,

Thanks for the information

I'm using bitminter so far, maybe I'll change if I care to look for better options :p

Have you ever tried to join Sidehack pool or ckpool? It looks as if there is a waiting list to join
these clubs. Also do the compacs have to be bought from Sidehack to have the
permission to join its pool?

Cheers,

Jeff.

To my knowlege it does not matter where you are buying the compac, just that you have one. (Which ultimately it should have first sell to sidehack or europe compacs).   As some were sold to are not penalized by purchasing from resellers (a lot of other countries were resellers)  But yes the club is capped at 30 at the minute to make it fun and not just have a ton. 

But check in at the club pool board to check more into it.   It is had some good community help.  Phil of course has done a lot of work on it, and crytoglance did a amazing job on tracking software.

Hello everyone:)

I got my compac in the post yesterday, and of course i wanted to test it at once  

I launched the the gekko cgminer software:
./cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u Jeff_59.worker1 --compac-freq 150
The miner seemed to work great, however i'm a bit puzzled. Indeed, i looks as if i still don't earn
anything

I mean nearly each time the task is confirmed i get no rewards

Did i make something wrong, or does it simply tell me that mining with one compac is not enough?

Regards,

Jeff.

[zOU]

You get shares to hash,
You have to "mine" them sucesfully
Once all the shares in a block are mine, the block is found and the reward is shared amongst people having mined it.

But your pool is not always the first to complete a block, so you don' always get a reward.

We can both mine a gold mine, but I may be the first to find gold on a certain day. Maybe another day it'll be you.
That's the concept

[bestcoin_59]

Hello zOU,

Thanks for your explanation. So, if i understand correctly:

1) When i get no earning for my contribution, it does mean that anyone in that pool get a reward.
2) When i get something, then i does mean that 25 has been shared between the members
of the pool. If anyone had the same miner hardware as mine, it would mean that there are 25/0.00000637=3 924 646
members in that pool. On the other hand i read that there are in fact 'only' 18 901 active workers. Does
it mean that an average worker in that pool owns miners that are 3 924 646/18 901=207 times
more powerful than mine?

Cheers,

Jeff.

[zOU]

The reward for the block is distributed according to the share processed.

So the more mining power you have, the more share you process, the bigger the reward.

Salu Jeff,

just a quick answer to ckpool (this is a pure solo mining pool).
You mine there for yourself, you don't get anny pay excapt you are solving a Block.
Then you will get the Reward for the Block -0.5 % wich is for con the pool holder.

nb: I live verry verry near of the alsac area, on the german side.

Jeff, as far as I can see you only got one BTC payment from the pool because it takes a delay of 100 blocks before the blocks that you helped finding pay out.
The confirmed ones on your graph were from before you started mining on that pool.
By now you will see every confirm give you a little bit of BTC
