View Full Version : Teach me questions
Hello all,
I have a few quick questions on wiring if you don't mind. I typically build RC aircraft, so all this electrical stuff is fascinating to me. In an RC build a 10% cushion/buffer from battery to say resistor or motor, is common. I noticed that isn't the case in saber builds. Why not?
My other questions:
Is over "ohm-ing"/ adding that buffer, bad for the LED?
Is the only "downside" a dimmer blade?
Why are Li-ion batteries the main choice? Li-Po seems much more popular. Or is that an RC bias?
That's it for now, I'm sure I'll think of more questions in 10 min or so.
Thanks!

We try to get our resistors as close to the proper value as possible. Sometimes we'll "under-ohm" a little bit (use a slightly lower value resistor) in order to overdrive the LED. Brightness is a huge draw for many sabersmiths. Using a higher ohm value than is needed will dim the blade.
Li-ion is chosen for its durability. Sabers take a good deal of impact. A damaged cell in a RC aircraft or vehicle can catch fire and/or explode. This will typically result in the loss of the RC device. A fire/explosion in a lightsaber can result in the loss of a hand. Prosthetic hands aren't quite up to the level of Star Wars yet, so trying to get an accurate Luke or Vader cosplay isn't a good idea. ;)
Seriously though, the li-ions are more durable when subjected to repeated impacts. I still charge them on a fireproof surface, and remove the batteries for charging if the saber was designed for it.

Thanks for the reply SS. Now I know. "And knowing is half the battle." - G.I. Joe
