All you have to do is follow the steps for other solo mining:
First, download the bitbar qt client:
- Windows zip - http://sourceforge.net/projects/bitbar/files/bitbar-win32.zip/download
- Official site for other builds (linux, source code): http://bitbar.biz/downloads
Set up a username and pass in bitbar.conf
server=1
rpcuser=USERNAME
rpcpassword=PASSWORD
rpcallowip=127.0.0.1
rpcport=9344
Download cgminer (http://ck.kolivas.org/apps/cgminer/2.11/cgminer-2.11.4-windows.7z) (http://ck.kolivas.org/apps/cgminer/) {Don't forget the Catalyst drivers and SDK}, then in cgminer input your username and pass, then set the URL in cgminer to http://127.0.0.1:9344
cgminer --scrypt -o http://127.0.0.1:9344 -u USERNAME-p PASSWORD
Or create up a custom .bat file (ie minebitbar.bat) and input the above code into the bat file in a text editor. Set your own custom settings for maximum hashrate.
Is solomining viable at this point? Hard to say, if your hashrate is high >2000kh/s, then yes, perhaps. Current difficulty has risen due to the addition of bitbar to coinchoose and to the exchange bter. I would expect difficulty to lower in the coming days, when it does, it would be a great time to solomine if you can spare the hashpower.
Alternatively, join one of the pools! Use similar settings to the above, but with the url and port changed to the pools, and the username and password changed to your workers
