I'm in the same boat kinda, trying to do a Calculon style build but not sure how he did his wiring exactly.
You'll need a board that can control each LED. Or at least one channel for the main blade and one or 20 for the quillons. The board will have settings you can edit for mA, staggered ignition and timing to match the length of the activation/deactivation font. Not sure if the diamand can do that or if you'd be able to access the board to wire a crossguard how you want.
Your board of choice for your DIY project should have a manual that can explain just about everything you need.
Good luck with your project!
