Therefore, things look and work a little different, especially creating posts and uploading images / attachments.

LED question

Postby jknightandkarr » Sat Feb 11, 2017 1:53 pm

I gotta kinda silly question. I am in need of .4" blue alphanumeric led displays, but there aren't any available that I can afford, do I had a thought, and wanted an opinion. How would a green led look behind a blue filter? Think it might look like the color of the old vaccume florecent display?
