Flux Capacitor Lighting
Using several sources on the web, screen shots from the movie and trial and error moving some parts around on the base, I settled on the locations shown below for all the parts. Key to this was the placement of the LED's and corresponding Solenoid bases. I labelled most of the holes below with the size drill bit i used. In hind sight, and for my next one, I plan on drilling the 4 "arc" holes smaller than the 7/64 in. shown here. That's just one of the many tweaks I'll be making on my next one.
