A B.U.D- block update detector, detects when a block is placed next to the water or destroyed, when that happens the water wants to flow down, lift the boat off of the pressure plate turning the torch on sending a pulse and well, hard to explain but you should check it out for yourself and give me a diamond for using my time to bring redstone to my pals at pmc! also you can use redstone ore and right click it to turn it into redstone ore (on), this is useful for secret bases that don't have a lever saying: please don't pull me! I don't open any secret doors or nothing!, lol see what I mean? people always pull levers or buttons they see cause they don't care for trespassing, some people are rude and will enter a home if they like, This fixes that problem, this can also be used for auto farms! it can detect when a melon, reed, or cactus grows and if you hook it up to a new piston you can make it harvest it, if you want more I need a diamond to help inspire me to do more!

Additional Notes

I planted some jungle trees cause jungles are awesome and you know it ;) also I got the idea from a youtube video, sadly this video was super outdated and didn't work anymore, so I had to do some trials and errors and lots of pain and misery to make a working one, finnaly after putting in a certain repeater timed just right I did it, I would really like a diamond to make mroe useful redstone devices!
