Redstone Devices

Once you advance far enough in your world, you may want to measure certain conditions, such as the wind speed or the time of the day.

The first is the Precision Clock. The Clock detects the hour, or, when toggled with Right Click, the month.

When in hour mode, the clock will output a strong analog signal where signal 0 means midnight or noon, and signal 11 means 11:00 or 23:00.

When in month mode, the clock will output a strong analog signal where signal 0 means January, and signal 11 means December.

You do not need a comparator to read the Clock's signal strength.

Next we have the Thermometer, which detects the ambient temperature, or the temperature of the device it is placed onto.

When reading ambient temperature, the Thermometer will output a strong analog signal where signal 0 means -40°C, and signal 15 means 40°C.

When reading device temperature, the Thermometer will output a weak analog signal where signal 0 means no heat, and signal 15 means Brilliant White.

You do not need a comparator to read the Thermometer's signal strength.

Mercury can be extracted from Cinnabar.

If you're having trouble getting the Mercury into a vial, try using a Vessel to transfer it into a Barrel, and then Right Click the Vial on the barrel.

The glass vial is also able to carry around variable amounts of fluids like a Wooden Bucket, and can safely hold Acids.

The Anemometer detects the wind speed. It outputs a strong analog signal where signal 0 means 0kmh, and signal 15 means 115 kmh.

You do not need a comparator to read the Anemometer's signal strength.

The Weather Vane detects the wind direction. It outputs a strong analog signal where signal 0 means North, and signal 8 means south. The signal increases as the wind direction proceeds clockwise.

You do not need a comparator to read the Weather Vane's signal strength.

Gates and Latches

There are many other kinds of blocks that can control redstone. Most of them can be crafted by stonecutting a Comparator, and can then be stonecut themselves, so you won't have to make lots of different devices to experiment.

A Pulse Timer can provide redstone pulses at arbitrary intervals, such as dropping items into a Blast Furnace.

The Sequenced Pulse Generator can be configured to send a combination of redstone signals at varying time intervals.

Need to provide a constant signal strength? The Analog Lever is perfect for just that.

A Threshold Switch outputs a redstone signal based on how full a container is. It works with both items and fluids.

The Smart Observer is a more advanced version of a regular Observer. It can be filtered and can also detect changes in fluid levels.

The Redstone Link can transfer redstone signals wirelessly.

Machine Covers

GregTech Covers can be placed directly onto your machines, and a lot of them will interact with redstone in some way. For example, the Machine Controller Cover lets you turn a machine off when it has a redstone signal.
