I am very very very new to redstone and as an attempt to get started into the plethora of different redstone projects available, I decided to create something fairly simple: a minecart route system device thing. I worked on this for approximately 2-ish hours mostly figuring out how hoppers work and how I can use an item filter to do things for me. Now, granted, this build isn't very efficient or advanced but I simply wanted to share it because it's one of my first devices that I have built. Feel free to download this and give it a try as well as give me some feedback as to how to improve it as it takes about 8 seconds for the minecart to launch. Thanks a lot!
