Repeater
Using   two Redstone torches in series can effectively extend your running   wire  length past the 15-block limitation. As of 1.0.2 (the July 6th  update),  there must be a strip of wire between the two Redstone   torches. Repeaters makes it possible to send long-distance signals  around the  map, but in the proccess slow down the speed of transfer. To  reduce  delays, you can stretch out the repeater so that some areas of   the wire  are consistently in the opposite state, but as long as the   amount of  Redstone torches, or, effectively, NOT   Gates is even,  the signal will be correct.

The North/South Quirk
A specific arrangement of torches which would normally be expected to behave identically to a repeater, causing a 2-tick delay in signal transmission, instead causes only a 1-tick delay. (See figure 1.) When constructed with the torches facing east and west, this arrangement causes the expected 2-tick delay, but when facing north and south, the second (top) torch changes state at the same time as the first, after only a single tick. The quirk can cause unexpected bugs in   complicated circuit designs when not accounted for, but it does have    several practical uses. For example, double doors require opposite power   states, but inverting one signal delays that door's response by 1   tick. The only known way to perfectly synchronize them is with this  1-tick  repeater. Another application is in creating a clock circuit  (see below)  with an even pulse width and period.

Finally,  as a  generalization of the double-door use, the North/South Quirk can   be used  to obtain two signals which are always inversely related   without the  additional 1-tick delay a NOT gate normally causes in the   second signal. (See figure 2.) This can be especially useful in  circuits where precise  timing is important, such as signal processing   that relies on the  transition of an input from high to low and low to   high (on to off and  back), for example by sending each of the inverse   signals through  separate edge detectors (see pulse generators below)   and then ORing  their outputs.

Delay Circuit
Sometimes it is desirable to induce a delay in your redstone circuitry. Delay circuits aim to do this in a compact manner. These   two delay circuits utilize torches heavily in favor of compactness,   but  in doing so the builder must be aware of the North/South Quirk. For   maximum signal delay, construct these designs so that the stacked    torches face east and west. For a fine-tuned delay, adjust the design to   rotate one of the alternating-torch stacks to face north and south,  or   add an additional stack in that orientation.

Clock generators
Clock generators are devices where the output is toggling on/off constantly. The   simplest stable clock generator is the 5-clock (designs B and    C). Using this method, 1-clocks and 3-clocks are possible to make   but they will "burn out" because of their speed, which makes them    unstable. Redundancy can be used to maintain a 1-clock, even as the   torches burn out; the result is the so-called "Rapid Pulsar" (design    A). Slower clocks are made by making the chain of inverters longer   (designs B'  and C'  show how such an extension process   can  be achieved).

Using a different method, a 4-clock  can  be made (design D). A 4-clock is the fastest clock which will  not  overload the torches.

A 4-clock with a regular  on/off  pulse width is also possible as seen in design E. This design uses  five torches, but can be constructed so that it has a  pulse  width of 4  ticks by employing the North/South Quirk. It is important  that the  orientation of this design (or at least the portion  containing  the  stacked torches) be along the north/south axis.

The   customary name x-clock is derived from half of the period length,    which is also usually the pulse width. For example, design D will   produce a sequence    on   the output.

Pulse Generators
A device that creates a pulsed output when the input changes.

Design   A will create a short pulse when the input turns off. By inverting the   input as shown in B, the output will pulse when the input turns  on. The length of the pulse can be increased with extra inverters,  shown in  B'. This is an integral part of a T flip-flop, as it prevents the  flip-flop  changing more than once in a single operation. Designs A and B  can be  put together to represent both the increase of A and the   decrease of A  as separate outputs, these can then be ORed to show  when  The input  changes, regardless of its state.

A pulse  generator  which causes a short pulse of low power instead of  high can  be made by  removing the final inverter in design B' and  replacing it  with a wire  connection. This is the type used in designs A and B of the  T and JK  flip-flops (when J=1 and K=1) to briefly place  these devices  in the  'toggle' state, long enough for a single  operation to take  place.

Vertical transmission
Sometimes   it's necessary or desirable to transmit a redstone state vertically,    for example to have a central control or status for several circuits    from a single observation point. To transmit a state vertically, a 2×2   spiral of blocks with redstone can be used to transmit power in either    direction, and the spiral is internally navigable (i.e. one can climb  or   descend within the tower).

If repeaters are  necessary,  there is a 1×1 design for transmitting a state upward, and a   1×2 design  for transmitting a state downward. Internal navigability of  these  designs inside a 2×2 tower interior can be maintained using   ladders.

Combination Locks

 * A door that opens when a certain sequence of buttons has been pressed.
 * (Note: A moderate understanding of logic gates is needed for this device.)


 * RSNOR Combo Lock
 * Connect   a series of buttons to the S-input of RS Latches. Feed the Q or   Q  (choose   which one for each latch to set the combination) outputs of the  RS   Latches into a series of AND gates, and connect the final output to  an   iron door. Finally, connect a single button to all the R-inputs of  the   RS Latches. The combination is configured by using either Q or  Q  for each  button (Q  means that the button would need to be pressed, Q  don't press)
 * Example:


 * With the automated reset it causes the correct combo to cause a pulse instead of a "always on" until reset.


 * AND Combo Lock
 * The   AND based combo lock uses switches and NOT gate inverters instead of    the RSNOR latches in the previous design. This makes for a simpler    design but becomes less dynamic in complicated systems and it also lacks    an automated reset. The AND design is configured by adding inverters   to  the switches.
 * Example:



Binary to Decimal
A series of gates that convert a 3bit binary input from inputs into a decimal output from 0-7. Useful in many ways as they are compact 5x5x3 at the largest.

These can be linked in a series from    one input source but it is recommended to  place an inverter before  each   input into the circuit to keep them  isolated from interacting  with  the  other circuits since some drive a  combination of High and  Low  current.

Need  clarification but some of these  may  also work as Tri State buffers or   as close as possible with  redstone  depending on your setup.
