How To Make a Canon Minecraft TNT (8/9 steps)
Step 8: The Redstone aspect
This is the aspect of the redstone the TNT gun, not yet the clock. As seen in the first image create a redstone line through the distributors (Crouch if you do not access their inventory when good click on the distributors). And add a repeater, so it must face the block behind the distributors. Do not set ticks on this relay. Then you will add the redstone that leads to the DTT launch. To do this place repeaters along the outside of the foundation, connected by some redstone dust in the corner. These will all have full tick value. Now we come to the green part. As in the third picture. Start by connecting the repeaters of the previous image for the first repetition on the green field. Put another redstone dust behind it on the corner and connect it to the next repetition. Then we come to the red part of the building. To do this, add a dispenser on top of the open block above the barrier, as you can see in the picture and then connect the redstone dust that leads into a repeater that will equip the dispenser. The two repeaters on the green and red wool do not have the ticks located from the default tick 1. Technically, you are finished here, and you can use it as a semi-automatic cannon without a clock. To do this simply add a button to the end of the orange part and press it whenever you want to photograph. Caution, do not use the button before the last shot already exploded, no system overload. If you want to make it completely automatic, following the next step.
