Javier Posted January 14, 2015 Share #1 Posted January 14, 2015 Hey, so, I want to build a R160 Exterior sign (and possibly interior, which ever is the easiest.) but the thing is I dont know the exact parts to the exterior sign. Do they use regular LED's or letter LED's? If anyone has /knows what parts I need to start building It would be awesome, Link to comment Share on other sites More sharing options...
Joel Up Front Posted January 14, 2015 Share #2 Posted January 14, 2015 They've been at it since 1981 and all I've seen them do is complain. Just complaints about everything possible... Link to comment Share on other sites More sharing options...
itmaybeokay Posted January 14, 2015 Share #3 Posted January 14, 2015 This isn't an easy task :-D I'm not sure what you mean by "letter LEDs". They use LED matrices. There are plenty of tutorials for 8x8 Led matricies out there, and that would be a good place to start. There's a MAX chip that's particularly good at driving them, meaning you just have to have three pins of the arduino driving the chip, instead of the 16 pins you'd need to directly drive the matrix. What I do know is that just like the way you'd drive the matrix using PWM (rapid blinking, painting the letters 1 column at a time) is exactly how the exterior signs work, which is why they appear distorted when the train is driving past. Anyway, if you have any questions let me know I've got a fair bit of arduino experience, but I've never driven an LED matrix bigger than 8x8.

Javier Posted January 15, 2015 Author Share #4 Posted January 15, 2015 Alright, so they use LED Bulbs? Link to comment Share on other sites More sharing options...
itmaybeokay Posted January 15, 2015 Share #5 Posted January 15, 2015 It's an LED matrix Link to comment Share on other sites More sharing options...
Javier Posted January 15, 2015 Author Share #6 Posted January 15, 2015 Ah, okay. Is it the same with the interior signs? Link to comment Share on other sites More sharing options...
Javier Posted January 28, 2015 Author Share #7 Posted January 28, 2015 I just finished the last LED matrixs on the sign and Im waiting on my new arduino to come. In the meantime I set up my R142 strip map with LED lights and connected it to my sound board so now when I finish the sign it will be like I have a little subway car in my room!
