Okay so I tried to get the other blade up and running but it powered off my PSU after a couple of seconds, from what I've been reading that's because it can't support the draw that the S1 is trying to draw correct?
But it's also pretty late so I may have just configured something incorrectly.

I might put the pencil mod back on the other side and look into it just so I can get both blades up and running on one PSU.

Thanks again!
