While these are originally designed for N, they should scale up easily for HO or O. Getting close to releasing these. Just need to do the write up on them. Took me a couple of weeks but I just finished the code today. Movement will be done by and Arduino with PCA9685 board and up to 16 servos. Code moves multiple servos at the same time and you can use three or two position semaphores. I added a bounce after movement feature as well. It is not totally realistic but it adds a little flair and there are lots of options for tuning each servo individually in the code. Multiple servos move and triple color semaphores are working as expected in JMRI via CMRI which was my goal. They can be customized with a variety of spectacles and blades I designed and mounted on ether side of the mast. Totally stoked I got this working, now to just do the write up.
Getting ready to release these. Just need to finish the write up of building and getting them into JMRI. They work really well and turned out pretty good. I estimate each semaphore costs about $4 with most of that being the servo to move it. You can flip or invert the spectacles and light boxes to get all sorts of positions and directions. You can cut the blade tip of if you want a straight edge variety and cut a notch for that variety. Did I miss any spectacle types? If so, send a picture and I'll see what I can do. Keep in mind this is N scale and I had to sacrifice accuracy for durability at times.
Very nice, I had never really considered having Semaphore Signals but seeing how great these turned out I'll probably find a place or two to have some, Thanks. Sumner
Decided to try a dual and it turned out great. Now to figure out how to setup two servos under the layout to move them.
You've really done an excellent job with these. Once you get the servo setup figured out I'd love to see a short video clip of these things in action!! -Mike
Man I'm nearly speechless.... that BOUNCE!!!!!! Wow! And the action is so smooth at that scale. Incredible. -Mike
Seeing the old NP semaphores in action in Montana, yours are legit! Accurate for sure, that motion when they drop!
