Wireless Jammer

The Wireless Jammer is an item block that blocks nearby wireless redstone signals.

Recipe
The Wireless Jammer is crafted with one Blaze Transceiver, one Blaze Rod, one Stone Wafer, and two Stone Wires.

Usage
Simply place the Wireless Jammer to begin blocking nearby wireless redstone signals. By default it is always On, but can be switched off with a redstone signal through its front end. Red lightning bolts will shoot out from its tip as it disables nearby wireless items (visually, those items' red bulbs will turn off). This lightning bolt will also damage nearby entities and slightly damage the player.

Disabling the Jammer or removing it will allow wireless signals to begin transmitting again after several seconds. The red bulbs of wireless items will eventually blink a few times before remaining on, showing that redstone signals are now being transmitted or received.
