RGB LED solution for DJTT Arcade Buttons

[pedroslopez]

Hi all!

So I've been wanting to make something with these sanwa arcade buttons that DJTT sells on here and have been looking for a way to RGB-light them kind of like the Midi fighters do.

What's the proper way to light them? What kind of LEDs do I need? Obviously a regular RGB LED doesn't quite work...

I found these (https://paradisearcadeshop.com/butto...led-rings.html) which seem to work, but the price is higher than I would like since it would drive the cost of the project up considerably with each button.

Thanks in advance for your help!

I don't know. Have you tested this? I would order one opaque button (like THIS ONE) and see how light travels through it using a single (bright) LED. If you get a hotspot, you might try 2 LEDs instead of only one. THIS GUY seemed to have a decent result from just one LED. Of course, you're probably going to want to have a responsive LED instead of just being on when pressed, but you get the idea.
