Late addition: a neon OPEN sign. The effect is extremely difficult to photograph—I'm almost embarrassed to show this video. It looks infinitely better in person--just ask @VonRyan who saw it run for the first time this morning.
Looks good, and the design is well done. Especially the old-school LED sequencer. Lookign at your recent designs, you have serious love for slow-speed motors for all sorts of applications.
I suspect that if you were to paint the red LEDs black before installing them, leaving only their tops unpainted, that would have minimized the light leaks.
Anyone know how to use the JSTOR site?https://www.jstor.org/stable/43518384I figured out how to log in.Says they were converted by applying 7" wide tires. Couplers and headlights were removed.I also says my photos were taken in Cleveland in 1925 and it lists a different photographer, but I got them from an Erie book that says there are in Youngstown.EDIT: I just went through my photos. There is no way those photos are in Cleveland. The peak of the roundhouse behind the locos matched the Brier Hill round house in Youngstown. The arrangement in Cleveland wouldn't match the photos.
But what about flange mismatch ?
No question.I did exactly that. I just did not photograph it as one of the steps, but all of the LEDs are painted black with their faces cleaned off.The problem is diffusion. No diffusion leaves pinpoint spots behind the letters, making them illegible. A bare minimum of diffusion at least gets the letters filled in, but then it leads to light leaks. And I believe the lack of a "happy medium" is due to the tiny size of the sign. All I could imagine doing to fix it is creating a completely separate, self-contained sign for each letter, and then one for the oval. Which would be a ridiculous amount of work. Maybe if I run out of stuff to do, I might try that someday... Until then, rest assured it does look much better in person.
Ah damn, I got Conrail all over me...
Nothing to do now but just cut off the hand
