    You should probably run separate power lines, or bring the power lines from the blade back to the crystal. If you do wire it through the crystal, make sure you solder the wires together, don't rely...

    You should read the manual carefully.

    Nothing bad will happen as long as you follow the manual, because 2 LEDs is well within the ratings of the NBV4.

    Actually, the NBV4 should be able to run it fine. The MOSFETs were upgraded from previous versions to be able to support controlling power to a pixel blades. You should really be able to run more...

    Soldering through makes it easier to solder to both sides since the wire is less likely to ping off, although one side would usually be surface.

    Even if the rated forward voltages are accurate, the green will operate at around 2A at 4+v. While communal experience will say that it will survive, it's still not ideal. The old "wisdom" that the...

    I think a lot of people like to psych people out of the crystal chamber, but I don't see why. I'm sure you can do it.

    Yes. You don't have to do anything, but that is recommended for a reason. I personally use 20awg. This has nothing to do with the CFX, it's physics.
