An EMF meter built into a prop RGB PKE meter, would be beyond cool (sux about the size thing). I wanted to let you know about this wire I found at a dollar store, it's an aluminum wire (probably somewhere between 10 and 14 guage in size), this stuff is great! It's lightweight, really flexible (it does great 90 degree angles, with a lil coaxing from a pair of plyers, LOL) And comes in all kinds of great colors, I used blue and green in a bunch of places in the build. It would work great for that wire that runs from the knob to the screen in the RGB PKE meter.
