Peckforton Light Railway - Semaphore signal controller - Part 2

The latest version of the semaphore signal controller using key-fob radio control. All the electronics (receiver, microprocessor, servo and li-ion battery), are now contained in a 3D printed sub-base, so that each signal will be completely self-contained. This makes deployment so much simpler. Peckforton Light Railway is my hypothesis of a three-foot narrow gauge railway which might have run in rural Cheshire (UK) to serve the copper mines and communities alongside the Peckforton Hills. It is a 45mm gauge, 15mm scale garden railway. For more information, see http://riksrailway.blogspot.com - Music "Starry" by Kevin McLeod (http://incompetech.com ).
