Reply to "Atlas O Amtrak Dash 8 Blunami 4408 upgrade"

Got the plexiglass piece for the relays made and also mounted them up to it, wiring is just temporary and will be cleaned up a bit better in the final version.

I also decided to make a plexiglass piece to put between the smoke unit and 4408, this should reduce how much heat gets to the 4408 by a lot.

It's just a piece of plexiglass cut to the shape and size I needed, with some aluminum foil glued to the smoke unit side (shiny side facing the smoke unit).

I ended up ordering the wrong TVS diodes. I needed bi-directional ones, but instead bought uni-directional ones. So I will place a parts order for the correct ones and hopefully they will arrive some time this week
