i'm looking for a diagram on how to build a led ring, similar to this. i was also wondering what people use for the base of it (the actual ring) when it's installed as one solid piece.
if anyone could help me that would be appreciated.
also, what happens if you use too high a resistor? and how high is too high (if i need ~68 ohm and i installed a 100 ohm, would that do much)?
