Complex Door Opener

Hello once again my friends! This is RM_Epic bringing you my third project that I have uploaded on Planet Minecraft. I have created a complex door opener using a top-down powered block system with a lever on the visible powered block at the surface, connecting to a three-torch input-output lights. The torch on the front side of the block is turned on/off by the redstone. The power cut on/off and it either opens or closes the door. Here's some images. I hope you enjoyed. Please drop a comment, a like, or even a favorite! That concludes my redstone device. I am RM_Epic. I wish you an "epic" day!
