I’m working on a small project that requires to backlight a small glass slide (4’’ x 3 1/4’’). Trying to build something like this.
My initial idea is to use LED strips on the back with an acrylic sheet to diffuse the light, but I’ve seen there are already backhlight built modules (not sure I’ll be able to find the right size or adapt one of those, though).
Also, I’d like it to be usb rechargeable, since it will be encapsulated in a frame/box and I’d like to avoid having to open it to replace batteries.
I’ve found this on youtube which is kind of what I’d need. It looks quite simple but I’ve never worked with LEDs and I’m quite lost on how to build it, mainly about what type of battery I’d need to power it… which I guess it’s something quite basic if you’re familiar with LEDs
Anyone around who could help me with it any time soon? Any guidance on this would be super appreciated It’s for a birthday present and I need to complete it in the next 2 weeks.
