This article discusses the redstone engine in Buildcraft version 3. For the version in Buildcraft 2, see here .
Redstone engines are the cheapest of the type of Engine and as such are the least powerful of the three types of engine.
Redstone engines, like all other engines, gain speed as they heat up, which increases their energy output per second. Unlike Combustion engines, they will never explode on running hot, except when not powering anything (see below). In fact, they produce more power when becoming orange-blinking-red and it is not advised to turn them off unless needed (again, see below).
Like the other engines, the redstone engine can be turned on and off using a redstone signal, and requires an active signal in order to activate.
Break it with a pickaxe to get it back.
Produces: 1 x Redstone Engine
Power OutputEditThe Redstone Engine has 4 different power outputs, depending on how hot it is, it will eventually heat up and reach the last (better) output.
Blue: Makes 1 Energy Pulse every 5 seconds (0.01MJ/t).
Redstone engines are most often used for powering things like wooden pipes when it's not necessary to move many items at once because they are cheap to produce and maintain. The minimum configuration takes only two blocks: the engine itself and a lever or redstone torch.
OverheatingEditAll engines in Buildcraft will explode if allowed to overheat. The redstone engine however can only overheat if not connected to anything at all.
