![]() I've mine ppcoin in merge pool for long period in 2012. You really should start to mine new alt-coin !!! So, every day you have double the chance to win 25 BTC than you have to win $10k, which is less and costs you probably a dollar or two to enter. Let's take the Powerball lottery as a reference as Earlz mentions, it has odds of one in 648,975.96 to win $10,000 one in 5,153,632.65 to win $1,000,000. ![]() So one chance in 330,480 each day or one chance in 905 a year (of course, changing difficulty has to be taken into account). How low the chance may be, it's still a lot higher than winning the ordinary lottery and way cooler :) Big chance will turn out to be nothing, but with some luck they will ever find a block and cash in 25 BTC. They don't really consume too much energy, so I just let them solo mine. Let me know if that works for you or if you run into trouble.I use mine in "lottery mode" as I call it. You may now logout and cgminer will keep running in the background and you can attach back to it any time. You can leave that screen by pressing ctrl+a d Which will attach you the cgminer screen. Once connected via ssh again type screen -r miner ![]() OK, now it is time to reboot and check if everything is working. Wher username and password are your worker credentials from the pool.Ĭgminer is started via screen, this gives us later the possibility to switch to cgiminer when we connect via ssh. Now we only need to start mining after the user logged in therefore we open /etc/rc.local and add su -l USERNAME -c 'screen -d -m -S miner cgminer -o :3333 -u USERNAME -p PASSWORD' This is just in case it gets disconnected for whatever reason so you don’t have to think about starting it up every time.ġ:2345:respawn:/sbin/getty -noclear 38400 tty1ġ:2345:respawn:/bin/login -f USERNAME tty1 /dev/tty1 2>&1 I will also configure the raspberry to automatically login after startup and start mining. Now add yourself to the plugdev group and you have access to the miner as “normal” user. You can check with lsusb -vįor Some Uart Bridge which most likely is the Erupter. SUBSYSTEMS="usb", ATTRS="ea60", GROUP="plugdev"īe sure to check if your idProduct is the same as mine. This is also necessary for the automatic startup I will go through later.įire up your editor as root and create an udev rule at /etc/udev/rules.d/les with this content: Now we setup udev so it allows us to access the miners as normal user, so we don’t have to start it as root. Now get yourself a place in a mining pool, you can check this one out don’t forget to add your Bitcoin address in the appropriate field or you will not get any payout. ![]() Get cgMiner via git, just so we can update to new versions easily.ĬFLAGS="-O2 -Wall". Sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev git autoconf automake libtool screen You will need the powered USB hub even if you mining with only one Erupter since the Raspberry only outputs 100mA on it’s USB Port and the Erupter needs 500mA.įirst connect to the Raspberry via ssh and install all needed packages. In this post I will go through the process of setting up a Bitcoin miner with the raspberry pi, cgminer and an Block Erupter Asicminer. ![]()
