Please explain why this redstone minecart-loader works
See attached images. I am proud that I was able to build this tool to make a chest-minecart pause while it gets loaded from a hopper, and when the hopper is emptied, the powered rail beneath it powers again and the minecart travels off. This construction is working perfectly. I admit I learned most of it from a video and slightly rearranged it.
The basic function is: When there is nothing in the hopper, then the various blocks cause the powered rail to have power. But if there is something in the hopper, then the various blocks cause the powered rail to lose power, so the minecart stops. It works great.
But, my problem is that I don't understand the logical sequence that makes each of the parts work in sequence!
Can a redstone genius out there please:
Look at the two attached images (one of the rail receiving power because the hopper has no items in it, and one where the rail is not getting power because the hopper has items)
Clearly explain the logical chain of events that makes it work. For example:
- The hopper has something in it, so it causes a redstone charge to come out of it into the block next to it.
- The redstone comparator then causes XXXX... this makes the YYYY...
Best Answer
When a minecart stops at a rail, it is able to be filled with the hopper's items, making the hopper lose items. When there are no items in the hopper, the comparator turns off, which powers the block it runs into, which also means it turns off the torch. The redstone torch gives power to the redstone below it, which powers the next block, which powers the rail, and the minecart is released.

How does a minecart Hopper work?
A minecart with hopper pulls in items lying nearby (within a range slightly larger than the cart itself), or inside a container directly above the minecart, at a rate of up to 20 items per second, eight times as fast as a normal hopper. It also picks up items that are lying on a block directly above the track.[Tutorial] Minecart Loaders \u0026 Unloaders
