Intro: Quick, Temporary, and Cheap LED Diffuser
Not ready to sand/embed your LEDs, but they're too bright to look at? This Instructable is for you!
I'm fiddling around with my Arduino and TLC5940, and I'm getting a headache from staring at them. But, I don't want to sand them down, or otherwise permanently diffuse them, and putting them behind a sheet of paper or typical diffuser won't let me clearly see the specific patterns I'm trying to achieve.
Step 1: Straws to the Rescue!
Amazingly, straws fit atop generic 5mm LEDs perfectly.
What you need:
Straws (Normal, cheap ones. Bendy-style optional)
LEDs you want to diffuse.
Step 2: Obviously...
After cutting, stick your straws onto the LEDs. They should rest nicely on top.
If you're anal-retentive like me, tape them together, so they stand up together.
My inspiration came from Mitch Altman's Trippy RGB Waves He used a straw as a diffuser, and I thought it was a brilliant idea. As such, I'm passing it on to you :)
