Gates and Latches

(Joshua Richardson, MC Circuitry)
Logic gates and latches are an enormous feature in redstone science. These circuits allow complex wiring and mind-blowing contraptions. It is basically a machine with multiple outputs and multiple inputs. The outputs are determined based on the state of each input. For example,if both inputs on an AND gate are on, the output will also be on. Hence it’s name “AND gate”, where input 1 AND input 2 need to be powered.

Below is a diagram displaying many logic gates, and below that is a description of each gate’s use.

(Minecraft Wiki - http://minecraftwiki.net/)

Input/output gate: Output on if input on
AND gate: Output on if inputs on
OR gate: Output on if either input on
XOR gate: Output on if inputs different
Rapid pulsar: Same concept as a clock, pulses output
RS NOR latch: Memory cell (Makes more sense with buttons)
NAND gate: Output off if inputs off
NOR gate: Output off when either output on
XNOR gate: Output off if inputs different
Repeater: traditional-style repeater diode, delays circuit
RS NAND gate: Outputs always on, however when a button is pressed, an output is switched off for the length of the button
5-Clock: simple 5 clock, can be majorly reduced in size

Redstone Lamps

Added in 12w07a, these redstone-powered blocks are one of my favorites. When redstone lamps receive power, they emit light at a level of 15, one level more than torches. This greatly simplifies complex lighting systems as you no longer need to use pistons to push a glowstone block into a hole. One feature to note is that power sources, such as levers and pressure plates, can be placed directly on them, and when they’re activated, they toggle the block as well. This does not work, however, with redstone torches, because when they’re on blocks, they’re powering every direction except the block on which they are placed.



Bugs:
- When breaking a lit redstone lamp, the item drop is displayed as a redstone lamp in its on state, therefore you cannot store unlit redstone lamps with lit redstone lamps in your inventory. An easy fix to this is to place the block down again, and while it’s unpowered, to break it again.

News - Minecraft 1.9

Apparently Minecraft 1.8 was not good enough for Mojang. It has been nearly a month since the release of Minecraft 1.8, and Mojang has already released a beta 1.9 pre-release, with many new blocks and features.

There are many new features in 1.9, but Minecrafters are mostly exited for the "Villagers". Essentially, these villagers live in the small randomly generated houses, found in update 1.8. These strange creatures are harmless, yet frightening.

















Another known feature appearing in update 1.9 is the swamp biome. This biome is much darker than normal, bereaved of life. Grass looks dead, tree's have darker leaves and suspend vines, and water is murky. Also, new with 1.9 are lily pads. These float on water and are found mostly in swamps.

Their are also many other tweaks, not yet confirmed. They can be found here. -Brandon Richardson

News - Minecraft 1.8

As many of you know, Minecraft 1.8 is officially available. It has been released today for the public, and if you havent downloaded it yet, update minecraft. Minecraft 1.8 is possibly the biggest update yet, with all sorts of new features:

+ Added a brand new biome generation code that simplifies life a lot and makes things much more exciting for the future
+ Added new mob; Endermen
+ Added FOV slider
+ Added brightness slider
+ Added randomly generated ravines
+ Killing a monster makes it drop experience orbs

+ Added critical hits that deal +50% damage, plus an extra point to make crits with weak weapons worth it
+ If the player hits a mob while falling, they always hit a critical hit
+ The game now keeps track of damage sources and types
+ Some damage type ignore armor now; drowning, being on fire (but not being IN a fire), falling out of the world
+ Ice now only spreads next to existing ice or from coast areas

- Removed Herobrine

Pulse Generators

Pulse generators, or "clocks", are devices which create a current that constantly toggle on and off. Pulse generators are variable, which means you are able to make different clocks for each frequency of flickering, to a degree. They can be used for many different projects such as an automatic dispenser turret and self-building bridges/houses.


Creating:

Clocks can be made many different ways. The most efficient clock in terms of required materials is a 4 clock, shown above.
This clock design is very unstable however, because the redstone torch burns out after a while if it is set to either 1 or
2 ticks (0.1-0.2 seconds), otherwise when set to 3 or 4 ticks (0.3-0.4 seconds) is it perfectly stable. The simplest clock, which can be up to 4 ticks, doesn't require a redstone torch, but requires 2 repeaters. Another design, which is semi-simple and somewhat costly in materials, is a sticky piston clock. It uses 1 sticky piston, a lever, as many repeaters as desired, wire and any piston-pushable block.

Repeaters

(For creating repeaters, see *Redstone Dust crafting combinations)

Redstone repeaters have three main fuctions. They act as a repeater, a diode and a delayer. They can be used to delay the charge given off from a button, they can also be used for pulse generator or clocks (see Pulse Generators for more information). They are the simplified and compact version of NOT gates, which have the same uses. Repeaters can be set to 4 different delays: 1 to 4 ticks. Each tick represents 0.1 seconds, so 1 tick = 0.1 seconds, 2 ticks = 0.2 seconds, and so on. Repeaters are generally used to "refresh" a current, allowing it to travel another 16 pieces of wire.

As wire/diode:

The repeater only accepts input from its "back" (the side closest to you when you place it) and only sends output to its "front" (the opposite side). It does not interact with any of its other neighbouring spaces. This makes it quite useful in tightly packed circuits.

Any of the following can serve as an input to a repeater when placed dirrectly behind it:
-A piece of redstone wire, which will automatically attach itself to the repeater (as of 1.7)
-A redstone torch
-A block charged by wire or any other method
-Any type of switch (See Switches)
-Another repeater pointing in the same direction

Any of the following can serve as an output to a repeater when placed dirrectly infront of it:
-A piece of redstone wire, regardless of the orientation
-Any type of block that can be charged
-Any device that can be controlled by redstone
-Another repeater pointing in the same direction

As delayers

As mentioned above, repeaters can be used as a delayer for redstone current. They have 4 different presets, each adding 0.1 seconds to the delay, and can be chained to provide longer delays.

Repeaters greatly simplify the construction of delay lines and provide far more granular timing than chains of redstone torches. For example, a repeater with a long line of redstone for delay would blink faster than the same design with repeaters set to four every other piece of redstone, allowing for more compact slowed down clocks.

News - Minecraft 1.8 Trailer

Minecraft's massive Adventure Update 1.8 has been leaked -- by Mojang right-hand man, Jens Bergensten, or Jeb. Minecraft creator Markus Persson is content with the leak, as shown through his subtle use of a winking emoticon in this tweet, and the following message, which says, "(I am fine with you using it. Make sure you get it from the leaked url we are hosting, though)."

















Jeb affirmed his part in the leak with yet another emoticon, in the long-eyed equals-sign style, on a Reddit post. Jeb had previously tweeted he would upload the jar file for "expert users," which is exactly what he did nine hours later. If you're an expert Minecrafter, download the file here and get your adventure started.

When a developer leaks its own game a few days early, we think that should just be called a release. But hey, what do we know?
