@Mallard4468 posted:Like most of us, I have more 154 crossing signals than 154C contactors. Since the 154C is hard to find and doesn't work very well anyway, I'd like to build a flasher circuit that can be triggered from an insulated track section. I know that such devices are available commercially, but I'm hoping that someone has already built their own and could help out - both as a learning experience and to save money. Please post if you've built your own, along with a schematic and parts list. Thanks.
I tried searching the forum, but couldn't find anything, so if a thread already exists please post it.
@Mallard4468 posted:Thanks for the options. Re the item shown above, I built a crossing flasher using it - works very well, but it costs $25, and I'm cheap.
I'm not sure you read what I posted:
Option1- even if you build them yourself and "save money" most flasher circuits are PER crossing light, so if you have 10 you need to build 10 copies, or again say you want to replace ALL of the 154C contactors- you have to build that many copies of the circuit. This is death by 100 papercuts
Option 2- buy 1 each $25 high current flasher, connect ALL of your entire layout and all 154 crossing lights to this flasher using a 2 wire bus, Trigger each of the 154 Postwar style 3 terminal lights using insulated rail as the simple trigger.
