For my Christmas lights display, animated to music broadcast over a low power FM radio, I needed a sign to let people know when channel I'm on. The vinyl letters are reversed and applied to the back-side of the plexiglass. The digits actually show 188.8, but by judiciously applying black vinyl electrical tape over the unneeded segments, I can show any frequency I want! This picture only shows blue, but I have full Red, Green, and blue LEDs and control for whatever color(s) I want.
The completed sign will be updated at the http://doityourselfchristmas.com/forums/showthread.php?26793-Post-your-FM-quot-Tune-To-quot-sign-here&p=379348#post379348 forum. |
