Need help on "Second tick"

[yabastar]

i literally cant beat it no matter what i try

I know this is a terrible solution, but it works!

Hint: do any of the logic gates output 1/green from only one pair of two inputs? And do you have a part that can make your inputs look like those?

[Stuffe]

Skratic having the ON component on the AND gate pin actually doesn't do anything. The output of the AND will always be that of the second pin

[Zaphod]

You have a single condition when you want the output to be active.

When input1 is "1" AND when input2 is "0"

The first thing you need to do is to establish these two signals.
This would be
* input 1.
* the inverted input2.

and then you AND them together.


resulting in

Input1 ----- -----
input2 ---inv----- (AND) ------- output

This is why I love this game, i'm so bad at logic gates. I love programming and I am good at that though.

Here one more solution )

A NAND with a permanent 1 is the same as an inverter.
You get the same effect if you connect both NAND inputs to the same source.

Zaphod
True, thanks.

[UnsignedRobin]

When you look at the desired output: It is only true, when

i1 is true AND i2 is NOT true

You have to build just that :) (you only have to look at the green outputs and build a circuit for that, in all other cases its automatically red, then)

Could do it how I did it in minecraft now that we have the delay component. I basicly made asynchronous logic blocks, that is one signal would go in a logic block, and it would output when it was finished. So I could chain these blocks one after another. I could make sure each sequence completed correctly and I could have multiple logic blocks running by themselves with a signal that indicated they were ready for output.

It doesn't feel like you have to go THAT far here as we got a global stable clock and the solutions here work fine. I just have a thing about asynchronous logic, I want to see if its possible to build a computer without a global clock.

[MarximusMaximus]

I think, at the very lowest level, you need some sort of "i'm ready" state... a global clock (leading and/or falling edge signal) is certainly the easiest of those at the basic electronics level, to my knowledge anyway. (A global one meaning that everything is at some level of known readiness at the same time, instead of "mini-clocks" or other semaphores for each component.)

(But I'm totally with you about asynchronous building. I do a lot of asynchronous and asymmetric style programming.)

I cheated with building 7x NOT+DELAY and fulfilled the truth table but not the task. I feel like this is not the first time I tricked my way around the task.
I also didn't know that I can rotate gates. Knowing that would have saved me hours. Was there a hint anywhere?

are you sure you did it with level "second tick" specifically? it's a very early level, and it's not supposed to have delay line unlocked

Good at programming but bad at logic gates? That should be impossible, try to look behind the syntax or even right at the syntax (think operators). Programming is in essence nothing more than applying logic to data structures generally larger and more complex than a bit. You just have to learn to see through the syntax and terminology.

You can even apply gate logic just using an if statement by using && (and) and || (or) operators.

In1 | In2 | Out
===========
0 | 0 | 0
1 | 0 | 1
0 | 1 | 0
1 | 1 | 0

in this case, the only condition that the output will true is important
we must think only for the second line
the answer is (In1 and not In2)
