Excelsior, please see my above post for the video.
I, too, dislike the slow animation, and have sped it up to match the ignition sound more accurately. I feel the speed I have it on now is appropriate to the font I have chosen.
I do not notice any corncob effect.
Thanks for the video! It was great seeing it in action. I'm glad to hear you don't have any noticeable corn cob effect. What type of diffusion did you use? I'm planning to build up my Roman Mk.1 with a Neopixel blade in the next month or so, and I'm trying to get some ideas. I figure I'll probably end up using some type of foam wrap inside of a TCSS diffuser tube, inside of a TCSS trans-white blade. My only concern is overheating the LEDs--I imagine they get pretty hot, especially using white for FOC.
I do like a slower ignition like Vader in ESB and Rogue One, but not too slow, if that makes sense. For other sabers, like a Luke ROTJ, having a fast ignition is just part of the saber's character. So again, I'm glad this is one of the parameters that can be tuned.
For diffusion, I used a salvaged Hasbro foam diffuser. My two neopixel strips, I extracted from the rubber sheath, and double sided taped them together, back to back, making sure I wasn't shorting something out. Then the two strips went back into one of the rubber sheaths for stability and protection.
The two strips, inside the rubber housing, inside the foam diffuser, went into the translucent diffuser and blade from TCSS.
