Phil Haigh<p>Building a two arm semaphore signal today with illuminated lanterns. The signal arms will be servo driven by these little beauties, once the circuit is perfected I’ll be getting some boards made together with 3D printed mounts so that they just slot into the baseboards. The circuits will be 12v powered and take a single input for each arm 0v or 12v for the two arm positions. <a href="https://mastodonapp.uk/tags/ModelRailway" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ModelRailway</span></a> <a href="https://mastodonapp.uk/tags/OOScale" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OOScale</span></a></p>
