Variable Redstone Emitter
The Variable Redstone Emitter, or V.R.E. for short, is a simple block that gives off a vanilla redstone signal of a given strength (0 to 15) to one of its sides.
When you place the VRE, it defaults to redstone power of 0. on top of it are two sets of diodes (mirrored, for ease of use) and a slider, indicating the current output value. Use the handy table below to lookup diodes and values (1 is diode ON, 0 is OFF)
| diodes | output |
 |
|---|---|---|
0000 | 0 | |
0001 | 1 | |
0010 | 2 | |
0011 | 3 | |
0100 | 4 | |
0101 | 5 | |
0110 | 6 | |
0111 | 7 | |
1000 | 8 | |
1001 | 9 | |
1010 | 10 | |
1011 | 11 | |
1100 | 12 | |
1101 | 13 | |
1110 | 14 | |
1111 | 15 |
A good example of usage is when using PneumatiCraft tubes and valves and controlling pressure flow, without the need for laying out redstone and torches.
