Swiss Railway Signal for 0 Scale

by Tom_JF

0 scale (1:45) SBB Signal L. 3-flammig. Space for 4 wires between the 2 mat parts. Lenses are made to hold 0805 SMD LEDs and need to be printed transparent. Can be printed at Shapeways (frosted detail and transparent acrylic). I have only printed the lenses at Shapeways (I do not have transparent resin). All other parts print well with my SLA printer. In the base (concrete) there is enough space for a decoder, based on ATtiny85. Design is almost finished by now. I will produce the 4 layer board at SeeedStudio.
