Ok, so if your looking for a simple way to defend ANYTHING with firepower, dont worry, I got your back, Basil is back! But this time, its a Bazooka firing some Buckshot. This one only depicts 3 being fired, but if you want to add more, use with caution, because everything MUST be equal in this cannon format, or it will very well mess the crap up and then you gotta clean up and regret it for the rest of your life.
Now you need to make it such a format that it is a 2. Like here:
The Lilly Pad is optional, only if you feel like you will mess up loading it. the stone slabs are for the TNT to stand on so they cant get swept by water.
Now you need the basic redstone items. This is where its tricky. You will be only using 1 lever, so basically you gotta set it on a timer, which is very helpful.
Heres a picture of what it should look like with the wiring.
Place ALL repeaters on 3 ticks, except the 3 touching the slabs. this is so the cannon is timing perfectly so all the TNT can hit the ground of effect. Then load it. This how it should be loaded and ready to go. Now go defend whatever your defending before its too late!
