Immibis’s Peripherals Mod 1.6.4/1.6.2/1.5.2

This block reads RFID cards held by players within 5 metres. It has no GUI and can only be used from Lua code.
It can also read RFID cards inside storage carts (within 5 metres)

No card inserted:

Blank card inserted:

Non-blank card inserted:

Busy writing:

(the red line shows progress)

Right click with a RFID card in your hand to insert the card.
Right click with an empty hand to remove the card, if there is one in the writer. You cannot remove the card unless the glass cover is completely open.

RFID card recipe:

You can also craft a card with any dye to change the colour of the white tab – this is purely visual and doesn’t affect anything else.

RFID reader recipe:

RFID writer recipe:

This is a peripheral that reads and writes mag-cards.

Right click while holding a mag-card to swipe it.

The green light shows whether the device is attached to a computer.
The yellow light shows whether the device will write (on) or read (off) the next card swiped.
The orange light is controlled through the API, and is intended to indicate that the computer is waiting for you to swipe a card.

Mag-card recipe:

Like with RFID cards, you can craft a card with any dye to change the colour of the background.

Mag-card device recipe:

This is a peripheral that plays square waves.

Despite the name, these will work over any distance – even through unloaded chunks.
Network data is stored in <your world=”” folder=””>/data/immibis’s-peripherals-networks.dat – if you delete this, you’ll need to break and replace every cable and modem before they’ll work again.

LAN modem
This peripheral is the interface between a network and a computer. It must be placed on the side of a block, but will stay even if that block is removed – this allows it to be used with turtles.

Twisted-pair cable
This is the cable you can use to connect modems together.

This uses blue wool, not lapis blocks!

LAN messages

LAN messages are strings, similar to rednet.
Each modem can send a maximum of 10 messages per second, regardless of size, and stores up to 25 unsent messages – if you try to send more, you will receive a “Buffer full” error.

Each LAN message is addressed to a channel.
There are 128 channels which any computer can listen to, numbered from 1 to 128 (“positive channels”).
By default, a computer listens to channel 1, and no other positive channels.
Channel numbers can also be below 1 (“negative channels”). If a message is addressed to a negative channel, it is received by the computer with that ID (eg, messages addressed to -5 will be received by computer 5) and also to any modems that are in “promiscuous mode,” which can be set using a peripheral function.

LAN messages also carry a sender ID. Sender IDs can be faked, unless disabled in the config.

This peripheral allows your programs to easily encrypt and decrypt things.
If you’d rather people have to write their own encryption programs, you can easily disable the recipe in the config.

Recipes

The middle slot must have 64 items. All 64 will be consumed.

This recipe will not work with automatic crafting devices.

Alternate recipe

This is a completely normal recipe that works with all crafting devices.
