I finally found a piece of working EL (Electroluminescent) sheet which I bought in Singapore three years ago (and completely forgot about it). My idea is to create a light up PADD with some touch screen elements in it. Unfortunately, the touch-switch circuit is using the human body's capacitance to sense the inout. Unfortunately, the EL is also a big capacitance. Right now, I have placed the touch-switch above the EL which showed dissapointing results. And I know what would happen if I put it UNDER the EL sheet, which is what I am supposed to do.
This is a Flashing Electroluminescent "No Smoking" sign
See the bluish-green gunk at the right near the cables?
That's bad news, but still workable
And this is what happens when you leave the battery there for years
Even if you do not switch it on, the chemicals from the battery leaked
and corroded all the contacts along with the cabling
If you'd like to have an ultra accurate PADD kit, you can contact Matthew Munson at matthewmunson_@_yahoo.com (You need to remove the "_" from the E-Mail first as these spam bots are nasty). And, if you like to have THE ULTIMATE PADD that has lights and sound, you can give Gerhard Mros a call at email@example.com and you will not be disappointed.
