Today I was rummaging through a crafts store and found some dark card board and translucent paper. The paper is available in different colors, so I can customize the color of the words to my liking. I cut some rough letters out of the card board and placed the translucent paper behind it.
This is how it looks like with a quick setup with a breadboard and an LED behind it.
Unfortunately I cut out the letters quite large, so the test wasn’t quite realistic. Nevertheless I’m optimistic 🙂
