Can you post some more pictures of the circuit?

The oven from the front:

see also manual industrial furnace

Check if there is coal in the furnace with negation (it is important that the comparator is at the side hopper - the repeater is optional if you build the negation (block with flare at the side) directly at the comparator):

AND gate with 2 inputs and the output (redstone lamp) - it is important that there is redstone between the torches and that the torch is also set on the left:

The clock for the blink clock (2 opposing repeaters at level 3 - any other clock will work):

Hope it helps you - if not then just ask

😀 You're not exactly working with compact redstone, but I think it's a cool idea.

I know. I'm new at this, too.
The main thing is to find all the raw materials easily 😀

Cool idea

Can you also show it how you set it up in the first picture?

I'm not a fan of these industrial ovens because it doesn't give you experience.

Good thing. Only I do not bring on the PS4 the clock from the 2 repeaters to work. Have managed, however, that the lamp comes on when the refill chest is empty. The state of the chest is more important to me than the one from the hopper.
Since the lamp is relatively far away from the furnace I have amplified the signal with 2 repeaters. Can using repeaters in the redstone line cause the clock not to work? The clock is either always on or always off.
The chests are brought to the same level with the help of additional funnels and dispensers. Funnels for falling objects, for climbing the dispensers (mouth upwards). Then the whole thing becomes more accessible. The whole repair is walled under the building, so that nothing is visible from the outside.

see the instructions for the industrial oven or item lift on this page...

if I want to gain experience, I go the Nether and collect 20min Nether Quartz with enchanted pickaxe - are then so about 30 Lvl...

So I also use the PS4 version of Minecraft - I noticed that the repeater clocks like to hang times (is because the always only certain areas are "online" - so only where the player is near - have it tested once and am thereby landed at about 380 blocks away, all circuits, etc. that are further away from the player, no longer processed)... Instead prefer to use the funnel clock - which always works, because it virtually restarts itself.
In my version there are 3 funnels behind the chest - so I have to fill in coal without end so that the lamp doesn't get the signal too early, that's why I took the last funnel in front of the stove, but it works just as well...
As you can see on the main picture, I also put all my chests on one level, the screenshots here are just for understanding.

Question: how do you get the 3 chests so close together?

In which one builds alternately a normal and a drop chest - works of course also with double chests...

Thank you.

Can you do that with the repeater clock also with a komperator clock @usj89

Any clock works - is only for the flashing signal - purely theoretically, you can also leave out the clock completely to save space - but then only have a continuous light when you need to refill ...

@tangens70
I don't know if you have an answer yet but here is mine:
You have to put a redstone torch at the redstone of the clock and take it down again immediately, with the right timing the clock will start blinking.

Good idea 🙂 I will definitely still build times
