, Sat May 28 2011, 06:15PMi was wondering how to make a restone transistor.
Who knows? not using distance benefits.

Could you not build and use a monostable delay circuit (http://www.minecraftwiki.net/images/8/89/Monostable_small.gif)? This would act like a transistor when the input is high.

What do you mean by a transistor?
Would an AND gate be sufficient?

In an analog circuit (varying voltage levels) you have a leg of the transistor that accepts a voltage (the "base"), which allows or restricts flow of electricity through the transistor along the "emitter" and "collector" legs. So, a small input on the base of the transistor becomes a big change in the overall resistance/current flow of the transistor. This is the basis for all amplifiers, including vacuum tube "valves".
In a pure digital world, though, you just apply an 'on' voltage (typically +5 volts) to the input base of the transistor, and it allows the output to read either high (+5 volts) or low (0 volts) depending on the voltage state of the emitter leg.
So, yea, a single digital transistor is basically an AND logic gate at its most basic.

a monostable circuit sends just a quick pulse… no? and gate would work i think but i will need also a rsnor latch for the on, off state. i'm just trying to find a way to do a circuit changer, like track changes direction to another track… so does redstone power goes on a line i chose.

I've used a simple RSNor to do a simple track changer. Output on chooses one direction, output off choses the other. And Minecraftblock0 I know has managed to make a four direction track switch using one simple RSNor. So if you just want to have a track switch, a simple RSNor should do the trick.

I have found that a monostable circuit in minecraft maintains a constant high output while the input is constantly high. However, there are much simpler methods such as AND or any other logic gate. I was just over complicating matters.
Vladspy, are you trying to set up a circuit so that the red stone signal can travel further? A repeater would do that and only take up one block.

As I understand it, a mono stable circuit is just an RS-NOR latch that has a delayed self-reset, so a press of a button (or input a high/on state) on one side of the latch causes one output to come on, then a delay leg turns the other side of the circuit on, resetting the latch causing that same output to go off. It performs the exact same function in the game as a single button press, with the added feature of being able to lengthen the on-state of the output as long as you need it for (just cram a bunch of repeaters on the reset leg of the circuit, all set to 4 ticks).
But yea, Kahr is probably on to something, you should explain what the end-game is you are trying to accomplish, the solution might be dead-simple, and has already been built on the server somewhere. Or, if you simply just want to learn redstone, Blinky has a bunch of circuits already set up on display in his redstone museum.

ok so let's say i have 1 line… that's the in line. i have 4 outputs.
i send a pulse down the in line… and the number of on's and off's in the pulse will choose one line of 4. so for the first line i leave i to 0, the 2nd line it's 1, the 3rd 101 and the last 10101, so the signal on the line would permit me to turn them on and off… and here i arrive to transistors… they would let me do that just fine…
so to arrive at the 3rd line… track changer… after the 1st line (original pulse 101) the pulse will be 1 the first one will change the state… and continue the route, after the second line the pulse will be 0 so it will turn on the circuit…. i could use an and gate but will just activate it 3 times in a burst. i want to keep a part of the information signal… for the others lines.
i just thought at a thing… it would be another line of redstone, the power line, it will be in sync, with the system so for 3rd post i will have info line (101) and power line (100), and in this case an and gate would work just fine… also with a ns-nor latch to remember the value… but is there a way without the power line… ?
The flaw with this idea it's how to make a system that will send info and power in sync.
So this input line would be the info line… this would allow me to have destination choosers for tracks… everywhere on my track with minimum resources and not be forced to stop to choose 3 times the same destination on different stations.
The input line would be under or between the track lines that we all know…

Yep, already been built on the server. But, its a lot more complex than what you imagine.
Discharge has already built the redstone part of your idea, not hooking it up to rail switches or anything. Just a mental exercise for him, I think. Its basically an ethernet simulator.
Basically, if you want to use a single signal line for multiple destinations, there are two ways to do it. Either send pulses to a simple counter circuit at the other end, or use something like what Discharge created; an ethernet simulator. In order for the ethernet simulator to work, you have to feed both the sending station and the receiving station a stable clock. That way, a zero is actually read as a valid input. This drastically reduces the number of pulses you would have to send down the line to form a 4 bit counter. In other words, if you want 1010 (position 1 and 3 on) that is the equivalent to the binary number 10, so you would have to send 10 pulses down a line to get the remote station to register binary 1010. If you have an ethernet simulator, you send a pulse, then wait the time span of another pulse where you send nothing, then another pulse, then another wait cycle, then the 'end signal'. On the other end, the first pulse triggers the first register to go high (1) then the second clock pluse from its internal clock cycles and there is no pulse from the incoming signal line, so it leaves the second register low (o) then these two steps are repeated again for the 3rd and 4th registers. So, in the space of 4 clock cycles you can send the equivalent of 10 pulses. Of course, if you need the destination set to binary 1111 this also just takes 4 pulses, instead of a counter circuit needing 15 pulses.
You really have to see Discharges ethernet set up to fully comprehend what I am talking about, I guess... but he is not on that much these days (hes at college taking exams I think).

i think i found a way (mentally) to use only one pulse
in sync with a power pulse so i would need 2 lines… but be very simple…
using repeaters and and gates… send a signal… and the power signal will be delayed so when i pass through the posts i put in again delayers so the info line and the power line will be in sync exactly at the line that i wish, and there and gate and ns-nor latch…
