Let’s face it, mining digital currency nowadays is hardly worth it. It’ll cost you more in electricity than you’ll make in [insert favourite coin here]. Having said that, ASIC miners are all the rage these days for Bitcoin mining (which has a difficulty that is sky-high and will take supercomputers to get anything from it). Not so good for folks who want to try the lower end stuff (such as Litecoin) which use scrypt cryptography. Enter, stage left, the new fad of USB miners which use hardly any electricity. The first wave of USB miners were Bitcoin only, but now they’re releasing dualminers which can mine both Bitcoin and scrypt coins. To use one of these, you need to get the latest video drivers first (Nvidia for me).

Avouons-le, miner de la monnaie numérique ne vaut pas vraiment la peine aujourd'hui. Il vous en coûtera plus en électricité que cela vous rapportera en [insérez votre monnaie préférée ici]. Cela dit, les mineurs ASIC sont à la mode ces jours-ci pour miner des Bitcoin (qui est d'une difficulté exorbitante et nécessitera des supercalculateurs pour en obtenir quelque chose). Pas terrible pour les gens qui veulent essayer des trucs d'extrémité inférieure (comme Litecoin) qui utilisent la cryptographie scrypt. Entrez, gauche de la scène, la nouvelle mode des mineurs USB qui utilisent peu d'électricité.

La première vague de mineurs USB étaient Bitcoin seulement, mais maintenant ils libérant dualminers qui peut à la fois la mine Bitcoin et des pièces Scrypt.

Pour utiliser un de ces, vous avez besoin d'obtenir les derniers pilotes vidéo premier (Nvidia pour moi).

Next, we need to get some software to run with the Dualminer. Unfortunately, none are available ‘off the shelf’, so we’ll need to compile a special version of cgminer ourselves. Download the git repository in a terminal with: git clone https://github.com/dualminer/dualminer-cgminer After the download is complete: cd dualminer-cgminer Before trying anything, make the auto and configure script executable. Open a window, go into the dualminer-cgminer folder. Right-click on configure and choose Properties. Click the Permissions tab and tick the box beside ‘allow executing file as program’.

Well need a couple of dependencies, so use your package manager to install libtool, libudev-dev and libncurses5-dev. Or use the terminal if you’re up to it. Time to get compiling. In a terminal: sudo ./autogen.sh sudo ./configure –enable-dualminer –enable-scrypt –disable-opencl –prefix=/home/USERNAME/dualminder-cgminer (obviously replace USERNAME with your username)

Continue with: make && make install Wait a little while until it’s all compiled, then run cgminer with: sudo ./cgminer --scrypt -o stratum+tcp://ltc.give-me-coins.com:3333 -u wakuangdenongmin.1 -p 1 NOTE: for me I had to run it with sudo otherwise it wouldn’t detect my device

Now wait. Probably quite some time. It takes me days to get about 0.01 of a Litecoin. The problem is exacerbated by the pool getting new blocks which displays: Stratum from pool 0 detected new block and the whole mining process grinds to a halt for a short time.
