Looking for the project parts suggestions. I have a sign holder: https://ac-order.staplesadvantage.com/i ... gavail_sc7 This is a sign for a microscopy facility, which is supposed to be dark. I want to place microscope instructions into such holders and have them evenly backlit. I'd be very thankful for any suggestions on how to realize that.
Thank you, tastewar. There's a small problem with that - the sign is A4 size. I'm guessing there might be some LED solution as an alternative? But then the problem is how to make the diffuse light without making the whole assembly bulky.
You don't necessarily have to etch the instructions into the plexiglass. If you rough-up a sheet of acrylic with sandpaper (or spray some clear satin varnish onto it), it will diffuse the edge-lighting. Put your instructions on a transparency, and they should light up nicely.
