You, sir, truly are a wiring genius. I love how you do all of this custom work, what no doubt amounts to countless hours spent soldering and doing this and that, yet you're so chill about it. "Yeah, I did this, I did that."

Nice humility.
I'm sorry if you've answered this before, but how do you get your blades to light up the way they do? I love how the light comes on slowly and sort of goes up the blade, much like it does in the films. I'd imagine it has to do with the LED coming up in brightness more slowly, but I don't know how you do it. About the only thing I like that my Force FX saber does better than my Ultra Sabers is how the light goes up the blade to turn on and back down the blade to turn off. I love that effect and would love to know how to incorporate something similar. What you do with your blades is definitely similar.
I can't remember if I answered this in an email but it does sound familiar. It may be I was working on a response but had to up and leave in the middle of it.
The lighting effect of your MR is referred to as scrolling. I went after that like a dog with a bone but its not a good place to start lol. Also the weight of the blade with LEDs inside(+1lb or so) would be bad for my wrist. Not sure if I would have been able to wire a crossguard saber had I taken on scrolling right off the bat. To achieve this effect without a lightstring blade, you are correct! The card will have to have the ability to control power on/off delay. With the right blade, led and battery you could reproduce a similar lightstring blade effect but just not as pronounced. Hope that helps!
