I started playing around with using ComputerCraft to control a BuildCraft oil refinery in Minecraft. The computer controls two banks of combustion engines, turning them on and off so they wont overheat and explode. My next step will be to add ccSensors support so the computer can monitor the engine temperatures instead of using a predefined duration. The source code for the ComputerCraft program is here: https://gist.github.com/3461305
