Hi again
I seldom ever play the radio so I thought that mounting it lower was not going to affect much. I wanted my gauges somewhere near the line of sight. Obviously the dash cover in my car is bad and something should be done with it.
My marble dash insert is subject to paint but I kind of like it.
I made some tabs on the ends to hold it in place and I want to make it easily removable as it is still in development. In order to minimize parallax, I glue gunned in the gauge along with a piece of two inch diameter plastic water pipe to angle it. I didn't have a light for it so I took a white LED out of a small flashlight and soldered a 2k resistor in series with it.
Instead of fishing for a wire controlled by the lighting system I just tinned the leads and stuck them through the dashboard switch of the rear window defogger. The light should turn on and off with the ignition It only draws about 7 milliamps.
