I have a stupid question - I'm doing my first big build, and I bought the U-Track trackball and LED lights addon. However, I didn't buy anything to power it. Do I need to buy the PAC64 LED controller? I know it says I can tap into a 5V power source (no idea how to do that), but even if I can figure out how to power it, there is no way for me to control what it lights up as right? Do I need the PAC64 to program certain lights for it?
I can't really find much documentation on it. I suck with electrical work (knowing what to splice and how to power it, etc). Any suggestions? Spending another $60 for a board just to power it seems kinda stupid. I guess I should have looked into it before I bought it - figured it was powered via USB or something.
