!!!UPDATE: Download cpuminer and build from tar http://sourceforge.net/projects/cpuminer/ git HEAD is broken and will not let you run configure.

If you have 800 Mhash/s GPU (Graphics card) i’m sure you often think about making your raspberry pi a dogecoin miner. Because why not :D ? It is not effective i warn you :) you will get around 0.34 khash/s that is about 2000 times less than your GPU :) and about 500 times less than CPU on your box. But its easy and fun.

I mainly did it for fun to see how it will react, work and what is the possible heat problem.

Again Why ?

Because DOGE, doge coin is THE NEW BLACK. Its future! An Irony on all crypto currency :) and its value is based on meme, laugh and happiness. This is much better than bitcoin :> at least for me

Connect to your raspberry pi

You will need:

1
2
3
4

  λ automake
  λ gcc
  λ git-core
  λ libcurl

if you are using like me 2014-01-07-wheezy-raspbian raspbian you will have everything ready :) one thing to install is automake and you can do this by typing apt-get update followed by apt-get install automake this is all you need.

lets get on the box! (default login/passowrd for this image is pi:raspberry)

1
2

10:54 kuba@pc12:~ λ ssh pi@192.168.1.22
pi@raspberrypi ~ $

(This ip address is just an example :D you will need to have a way to find it in your network.)

Now all you need to do is to clone CPU miner for it.

1

git clone https://github.com/pooler/cpuminer.git

This will download your mining software on the raspeberry pi, next we need to compile it and run!

pi@raspberrypi ~/Workspace $ cd cpuminer-2.3.2/
pi@raspberrypi ~/Workspace/cpuminer-2.3.2 $
./autogen.sh
... script will take some time ...
./configure CFLAGS="-O3"
make

This will compile and build the minerd binary that is ready to start mining :). Well you need to do one thing, join a doge pool. I’m not gone go into details of solo mining vs pool minnig :) i’m just a simple miner :D

If you need more info on mining pools you should check this topic http://www.reddit.com/r/dogecoin/comments/1tn8yz/dogecoin_mining_pool_list/

I personally at the time of writing this post i’m using small pool called chunky pool :).

Starting to mine!

Now we have software lets actually mine something :). You will need to create a shell script that will start minerd on your raspberry pi. My looks like this

1

./minerd --a scrypt --threads 1 -o stratum+tcp://pool.chunky.ms:3333 -O dogedogedoge.pi:password

make it executable and run! Yay you are a dogecoin farmer now! CPU mining is not the most optimal but hey..its all just for lolz :)

Heat problems ?

For me 2 hours of mining on raspberry pi did not generate any extra heat or stuff like this, seems to be stable. I was worried it will got nuts on this topic but i was proven wrong.

Summay

This sucks in terms of speed, you will get close to none speed because below 2 khash/s its not even worth it, you will not be on any stats on any pool even listed, periodically you will actually hit the jackpot and get a success pimping you to 2khash/s for about 60 sec but that is just a lie, you scored a win and this will give you some parts of doge. Last i checked you were able to get around 0.67 doge per hour of your raspberry time. That is really really bad as pretty basic GPU pimps you to 600+

Cheers :) Hope it helps! Much fun, so currency.
