The meteoric rise of ethereum has fueled something of a gold rush for people looking to get in on the action by mining ether themselves. This requires building a custom “mining” computer from scratch, which isn’t quite as hard as it sounds.
In this how-to video, Motherboard contributor Daniel Oberhaus walks you through the step-by-step instructions for building an ethereum mining rig from the ground up. By the end of the tutorial you’ll be well on your way to mining ether and contributing to the maintenance of the ethereum network with your own computing power.
