Ok, an update. Build went very well.
Neopixels in the main blade, as well as in the Tridents.
Fonts installed are Son of Darkness, The Broken one, Unhinged and X Guard. All great fonts.
Delay on Tridents are perfect and really "movie" accurate. KyloDavidson's #371 blade effects are great. Just have to tweak some unstable flame crackling via the SD card.
Hilt is very movie accurate like the other two 2017 Disney Parks Exclusive Vader and Rey/Luke/Anakin.
Below is a pic of the crappy Disney electronics. Simple board and LED blade string. Looping hum sound on a 1/4 watt speaker with random flashes on three AA's. Blade ignites/retracts in tiers. Good enough to put in a hilt for a kid like I did with the other two Disney internals that I gave as as gifts.
The other pic is TCSS parts with the CFX and chassis discs attached to the cool Kylo pommel internal seen in the windows.
