I've been working on an automatic minecart station for mining, ( sorry for no pictures because the upload isn't working :() and i have a problem. How do i change an "on" signal from an rs nor latch to a quick pulse? I'm going to have a storage minecart dispenser stacked vertically with a trapdoor and I need a pulse once a cart comes in.
(The rs nor latches are there to switch the tracks so once a cart comes in another one can stop becide it and so on)
Wire the output from your original rs nor to another rs nor. Split that input wire into 2 lines so it goes into both sides of the second rs nor. On one of those lines (test to see which one needs it), put a tick delay on it. In essence, what this does is puts the output state of the second rs nor to the on state and then once charge reaches the other half, it turns it back off. This creates a pulse. Also, you might need to apply an inverter on the final charge depending on how your rs nor is oriented. The only thing is, this will create a pulse only when the first rs nor turns from off to on, but not the other way around. If you want it to pulse every time the output changes, that will require a different circuit. Also, if I am confusing you, look up for info on monostable circuits on the minecraft wiki. Hope I helped.
Edit: I couldn't help myself. Here is the wiki info you would probably want to see.
A monostable circuit sends an output pulse of determined length when triggered by an input pulse. They can be triggered by either a rising or falling edge of a pulse or both. The term monostable refers to the fact that only one state of the circuit is stable, while the unstable state reverts to the stable state after a set period (a bistable circuit is a latch).
A device that turns itself off a short time after it has been activated. Design A consists of an RS NOR latch and delay hooked up to its reset. The trigger input activates the latch's SET input, and after a delay set by the repeaters, the RESET activates, turning the output off again. The delay (e.g. the length that the output is high) can be set to any value by adding repeaters into the chain.
As a pulse will often have a shorter duration as it passes through complex circuitry, monostable circuits are useful for re-lengthening the duration, as the output always lasts the same amount of time, regardless of input duration.
It can also be used to delay a signal by using its reset signal as output.
Design B is a more compact version fits into a (3x2x3) space. Very short pulse and repeater has to be set to one of the last two settings in order to work. Repeaters can be added to lengthen pulse.
Alternatively, design C, a (7x2x1) vertical device can be built to fit neatly against/into a wall. As in the other cases, the length of time that the output is high can be adjusted by adding or removing repeaters. This design lacks the RS NOR latch of other designs and will only be useful in constant-input circuits. For momentary circuits, this design will not lengthen an input signal like the other designs, just cut the signal early.
A compact yet simple 2x1xn device can also be built if you're constricted to long hallways with little room for width. However, due to the design, this only works with pulsed inputs and not with constant-input circuits. Unlike the previous designs, however, it can deal with 1-tick pulses. Design D1 shows the basic device that lengthens the incoming pulse by 1. Pulses can be lengthened more by adding repeaters and/or increasing their delay, as in D2. Unfortunately, this particular design only works properly if the incoming pulse is at least two ticks long. Design D3 shows how you can skirt around this problem, increasing the size to 3x2xn. It lengthens pulses by 7 and works with any length pulse. Note that the number of ticks the device lengthens the pulse by is equal to the sum of the delays on the repeaters in the design, not including the first one.
so you wasssssssssssssasdfasfasfdasfasfasdfdasfdasfdasfdasfdasfdasso ssssso you want it where u have 4 karts stacked in the hopper and nothing on the togo pad. when a kart comes in and is now the 5th kart in the hopper it triggers the pulse to take the first kart and put it on the togo pad to be filled with stuff? If so this is a bad adea its better to have more hopper space then karts on the path and encase the whole track with only enough room for the karts themselves so nothing stopes them from moving. This way the hopper can be full and not be sending karts to the togo pad. I actually have a piston hopper that takes up way less space and is way better then the door latch
If you want the pulse to happen every time the output changes from on to off and off to on, then an edge detector is your best bet. Not as familiar with them personally, but they are right beneath monostable circuits on the pulse circuits page of the minecraft wiki.

Hold on, Sparky. I believe the OP wants a single pulse when the SR latch is set, not a monostable latch resetting itself. From the output of your RS NOR latch, throw down a rising edge-triggered monostable circuit. Here are a couple designs I like to use.
^^^ Not exactly monostable, yet it performs the same task as a monostable circuit.

Obviously the design you showed is simpler, more compact, and probably better for what OP needs, and I do know how it works, but I mean, isn't what I suggested also a rising edge triggered monostable? I was basically describing the design A from the diagram I posted. You make it sound like an rs nor based monostable wouldn't even work... I know I'm not a redstone wizard like you, but I do play with redstone pretty often and I just want to make sure I'm not fundamentally missing in my understanding of pulse type circuits. As I'm writing this I am testing on my redstone world both the rs nor based monostable I provided and the design you showed and they are both responding exactly the same way to a charge being turned on and off. I'm not trying to say your wrong, because I can clearly see how the design you use is nice and simple and compact (and I'll probably use it from now on), I'm just really self conscious about whether I'm misinforming people.

Oh no, not at all. A monostable latch is still a monostable circuit. A monostable latch is just a small part of the group. It's the same thing between an RS NOR and an RS NAND latch. They are both SR latches, and the function is identical, they're just made differently. In some cases, a monostable latch is more suitable than the designs I suggested. For example, they are much more effective when you want to sustain a pulse, rather than limit one. That was even my suggestion for someone awhile back. I have a very nice and compact model too, and unlike those previous circuits, this is my own original (I think/hope.) design.
EDIT: And yes, all monostable circuits are edge-triggered. The mechanism can also be altered by NOTing the input, which will cause it to activate on the inverse edge.
