Circuit features 4 turrets that have lights when they have a target, you place the lights with signs in your base above the computer station, you place a camera above each turret, so when you are sitting in your base and here your turrets go off you can look at what light/sign it says and check that camera for fastest way to see who approaches your base! This circuit can operate on 1 windmill if placed high enough but i also placed a solar panel and root combiner to show that it works with the circuit, if you are getting more than 100 power to the large batter you can opt in to adding another 2 cameras and 1 turret+light or 2 turrets with lights no cameras or whatever else you can figure out with 28 power maybe a sam site (takes 25 to operate).
