Activity Detector

The Activity Detector is a simple Cover that can be attached to all GregTech machines. When attached to a machine, it blocks interaction on the side it has been attached, and in stead emits a Redstone signal (strength 15) whenever the machine is working. For normal machines, this means whenever the machine is processing items. For Boilers, this means whenever the Boiler is burning fuel. It can be used as a form of simple remote monitoring, to see if and when your machines are in use, or if your Boilers have fuel.
