Redstone Dust is a vanilla Minecraft crafting, building and brewing ingredient. Redstone Dust is created when Redstone Ore is mined using an Iron Pickaxe or better. It can also be obtained by placing Redstone Ore or Nether Redstone in a Furnace or Macerator. Redstone Dust can be placed on the ground to create a Redstone Wire. Redstone can also be crafted into a Redstone Torch or a Redstone Repeater. These items can be used in more complex Traps or Redstone circuits. In Tekkit, Redstone is a very critical part of crafting; it is used to craft many BuildCraft and IndustrialCraft items.
Redstone Dust can be placed in a BatBox, MFE or MFSU in the lower slot to generate 500 EU/Redstone Dust/tick. This can be very useful if you don't want to set up EU power generation. For maximum power output from Redstone Dust it's recommended to hook a Energy Condenser filled with Redstone Dust up to a MFSU with a Filter in between. The MFSU has a max power output of 512 EU/tick and Redstone Dust can be consumed at 1 item/tick, so the MFSU will be able to output 500 EU/tick. The MFE and BatBox have a maximum power output lower than 500 EU/tick, so it's necessary to use a MFSU for maximum power output.
Restone dust can also be used to generate EU by placing it in the power slot of a Charging Bench at the following rates.
Charging bench Mk1-64 EU per Redstone dust
Charging bench Mk2-512 EU per Redstone dust
Charging bench Mk3-2048 EU per Redstone dust
Redstone Transport Pipe
