As part of a DIY electronics project, I want to use LEDs to create a glowing effect with a crystal ball.
I found a perfectly clear crystal ball that looks exactly like this:
I tried combining it with an appropriately sized ring-shaped set of LEDs. The LED ring is big enough for the bottom of the ball to fit in it but not big enough for the ball to pass through it. The LEDs are controlled by an Arduino and can change color, intensity, etc. They look like this:
I was hoping to achieve a luminescent effect, i.e. I wanted the ball to glow. A little extra light shining off of the LEDs is fine, it doesn't have to be perfect. However, in my attempts thus far it seems like the light from the LED kind of lights up the surface / sides of the ball, but it doesn't look like the ball is glowing from within. Just the opposite. It looks like the ball is dark and there's a halo around it.
