Hey everyone!

I've been lurking around for some time, admiring all the sabers that I've seen on the forum. It finally gave me the drive to start building some of my own.
Currently, I'm thinking of first learning to build a few sabers with the MHS module. Though I have a few questions about the components:

- Which is better: single LED or Tri-Cree LED? And what's the difference, besides 1 vs. 3 LEDs?
- If I wanted basic sound (ignition and humming, maybe swinging sound too), which sound board enables me to use such sounds?
- How do you know what resistor to use?
- A momentary switch means that the LED will only turn on if you keep pressing the switch, am I correct?
- What disadvantages are to using acrylic paint? Or is powder coating a must?

I hope you guys can help me answer these questions. I have no experience building sabers, so please forgive this young Padawan.
I'm a fast learner and I have no problem getting most of the required basic tools to get the job done.
