Chris Johnson - Home Miner Tools

Written by someone who actually runs this stuff

I'm Chris - an IT specialist and home Bitcoin miner in Oklahoma City. I run a Bitaxe Gamma, four Canaan Nano 3S's, a Nano 3, and an Avalon Q. I built this site because most home mining content is written by people who don't own any miners. Everything here is based on hardware sitting in my garage and office right now. More about my setup →
