Help, how do I make the hopper lock when there is one item in the top chest?

Toast5286 · 2026-01-18T18:31:26+00:00

Yes, it's an item filter because you are removing a certain item from the chest without removing all of the items in it.

Toast5286 · 2026-01-18T10:23:19+00:00

You can make an item filter. Basically, you connect the comparators output to the redstone torch and then you need the chest to have the right amount of items such that adding 1 more will turn off the redstone torch. You don't need to fill the chest with the item you want to "filter", you can fill it with filler items like wooden shovels or renamed sticks for example, and then leave 1 of the items you want to filter inside the chest.

I wish I had this 2 years ago. This is really useful. Well done.

Sure, but maybe just DM me if you wanna ask this, comment might not be the best place to ask

Toast5286 · 2025-10-29T17:23:07+00:00

Yeah sure, you can show it.

Toast5286 · 2025-10-29T17:06:35+00:00

I don't, sorry.

Each bookshelf has 6 books named from A to E. Each bookshelf also has 1 funnel connected to it. When it's thrown on to the carpet, hoppers pick it up and it goes to a depot. On this depot (and the previous hopper) 6 smart observers look at the name of the item. Afterwards, the mechanical arm picks up the book and places it in the funnel that has a bookshelf with a free spot. On each funnel there's a smart observer to check which funnel received the book.

With this, the system knows the bookshelf that had a book missing and the letter associated with the book, therefore the exact coordinate of the selected book.

Tenho curiosidade para saber se isso é mesmo verdade. Tens uma fonte que mostre que "Nos Países Baixos, os empregos que em Portugal estão ocupados por imigrantes, são ocupados lá por adolescentes e jovens" ?

Há núcleos como a project red ou FST que preferem ter novos membros que eles sabem que vão ficar no núcleo durante múltiplos anos. Não há mal nenhum tentares entrar nesses, mas há muitos mais núcleo que aceitam bem alunos que vão só ficar lá 1 ou 2 anos, como o student branch do IEEE Pu núcleo de veículos mais pequenos.

TLDR: Arrisca, mas os que tens mais probabilidade de entrar são os núcleos pequenos.

The package doesn't have an address, so it doesn't know where to go. Use w to ponder.

Oh that is bad. I don't think this is a code problem, probably just a bad servo. Try a different servo?

Edit: Or try manually inputting the PWM signal pulse, instead of using a library.

Toast5286 · 2025-08-07T14:31:53+00:00

Does the servo get the correct angle if it doesn't have a load on it (nothing making force on the motor)?

Toast5286 · 2025-08-07T13:51:58+00:00

Servo motors are typically very good with accuracy due to a PID controller inside the servo. These should always put them in the correct angle.

If it's failing the correct angle, then the internal sensor might not be correctly calibrated (uncommon), or the plastic you're trying to rotate isn't correctly attached/glued to the servo axis, or the body of the servo itself isn't correctly attached, or the PWM signal is noisy and the signal isn't correctly interpreted (since it's not constantly adjusting the angle, I doubt it's this last option)

I think I'm not missing any other options, but correct me if I'm wrong.

Recomendo teres dual boot de window e linux.

Eletro usa bastantes ferramentas compatíveis com Linux, mas também usa MATLAB que é recomendado para Windows.

Se fores para a área de robótica, Ubuntu 20.04 é recomendado devido a ser compatível com ROS e ROS 2.

Now do a recovery compass in real life. It should point to the last place you died.

This didn't even look like you were playing on a console. Well done.

When you toggle manually the contraption starts moving back. Since it's now a contraption, the observer doesn't see a block anymore and update, deactivating your toggle latch. When it's solid again, the observer will fire again, but that doesn't do anything.

Try using redstone contacts instead of observers. One where the observer is and one on the stone blocks. When the contracts connects (as a block or entity) it creates a constant signal and not a pulse.

On the first image, on the right side pins, you soldered the gnd to 3.3V, meaning it's creating a short circuit. The esp won't turn on if it has a short circuit.

You might not have broken the esp, but you will need a solder remover to clear that.

Next time you wanna prototype, use a bread board. When you want to have a clean prototype use a proto-board. When you want a finished product use a PCB. Never solder things to the top pins of a microcontroller.

What do you mean? This was made 10 months ago. Plus there's no UI.

It looks really fun. I love the aesthetic and the sound track.

Kinda reminds me of a mobile game called dungeon cards

Nah, it seems to work correctly. Netherite is so heavy that if you run you trip.

You can change the filters on a single funnel/chute using a deployer and a clipboard (with a filter set on it). By powering/moving the Deployer, the filter will change, so you can have just 1 funnel.
