G gauge crossing gate

thingiverse

Servo operated grade crossing in 1:24 scale for G gauge garden railway perfectly complements small spaces. Three 2mm LEDs fit seamlessly into the arm, while ten 10mm LEDs illuminate the targets with precision. K&S tubing's 7/32 and 5/32 diameters provide a sturdy framework. An Arduino microcontroller expertly pairs with infrared receiver chips and infrared LEDs to detect trains approaching, thereby operating the crossing gates in real-time. A bell sound remains on my to-do list for future enhancement. The vibrant red stripes are carefully painted onto the surface, showcasing a touch of finesse not typically associated with printed designs. To assemble this magnificent piece, cut 5/32 tubes approximately 6mm long to secure the "igloo" to the manifold. Pressing the two components together until they make contact ensures accurate spacing for the target lights. The 5/32 tubing generously allows for two #26 stranded wires to be neatly routed beneath the servo, which has ample space for connections. My specific servo measures 22x11x20 millimeters in dimensions; you may need to modify the "servo B" files to accommodate your unique servo model.
