Easiest/cheapest way to light a redstone lamp when mobs fall through tunnel onto hoppers

Easiest/cheapest way to light a redstone lamp when mobs fall through tunnel onto hoppers - Concrete modern platform with benches columns and advertisements lighted with bright white illumination

I am playing an MCPE hermit chunk map. There is 1x 16x16 chunk for me to work with, and so far no access to the nether. I have limited supplies, so the cheaper the better. Also, since I do not currently have access to the nether, comparators are out.

I have a mob grinder with a 2x2 hole down the middle. The mobs fall down this hole onto half slabs, die, and their items are collected by hoppers underneath the slabs. I am trying to find a way to visually tell when mobs fall through. I can either find a way to detect them falling in the hole, or their items being picked up. Either would be fine with me.

I would prefer to have a redstone lamp light up because I feel this is the easiest to see form a distance. I am currently on MCPE 14.2 (Windows 10 version, but basically same thing in this case)

Best Answer

To detect if an item has been collected by a hopper, you can simply place a comparator adjacent to it, with the two-torch side touching the hopper. enter image description here

The repeater then amplifies the signal so it does not matter how many items are in the hopper. Once we add an item...

enter image description here

We now know that there is an item in the hopper.

How do I get a always lighted Redstone lamp?

The ability for lit redstone lamps to drop lit redstone lamp items via Silk Touch has not been removed, however. As a result, attempting to obtain a lit redstone lamp this way in this version crashes the game with a NullPointerException. Lit redstone lamp blocks now drop unlit items regardless of tool.

Do you need silk touch for a Redstone lamp?

Do Redstone lamps stop mobs from spawning? A. Hostile mobs, such as skeletons and zombies, will spawn in light levels 7 or lower. A player can keep hostile mobs from spawning in an area by lighting up the area with Redstone Lamps.
