This is an autominer, but it works a little differently than blocks such as a quarry, with a focus on convenience. The machine, when it has enough power, scans blocks near it, following a bell curve pattern. It uses a MJ per block of ore mined, and 10 kJ per stone block it scanned. The types of ores it seeks out can be configured, by putting the ores you want to mine in the top row. Redstone, coal and diamond ore are mined by default, as those ores are hard to obtain without the silk touch enchantment.
