Psidust

To get Psidust, you need to start by crafting a CAD Assembler and an Iron CAD Assembly. Place down the CAD Assembler and put the Iron CAD Assembly in it to construct a very barebones Casting Assistance Device (CAD). From there, drop some Redstone and Lapis in the world, preferably at a 1:1 ratio. Equip your CAD, point at the dropped items and right click to make your Psidust.
