Minecraft Light Sensor

Ever wished you could have Minecraft ‘machines’ buttons / switches / pistons etc that were triggered by light or lack thereof? Like lights that only turn on when it is dark? This Minecraft light sensor is an impressive piece of Minecraft engineering that will take your creations to the next level of complexity. Check out the video tutorial by EthosLab. (Yes it’s 22 minutes long. Think of it as a test of your concentration span. Why, back in the old days, people could pay attention for an hour or more!)
