uranium marble

This project was created on 10/06/2015 and last updated 10 years ago.

Description

Seven UV LEDs facing inwards on a circle around a uranium glass marble, wired as a ring oscillator to create a beautiful glowing/spinning effect. This is my take on the original design that has apparently been around since at least 2009 (at 26C3).

Details

have you tried to make laser with uranium glass?However that could have made you cancer.

  Are you sure? yes | no

Thanks for the reply, I got some 385 and some 400nm from digikey, the 400nm were cheaper and work better

  Are you sure? yes | no

Very nice!

What wavelength LEDs did you use?

  Are you sure? yes | no

Daniel wrote 02/15/2016 at 11:06 • point

Sorry, a friend had those LEDs just lying around so I don't have any info on that. You can clearly see them emitting visible light... if that helps. Not sure if the marble reacts to one specific wavelength..

  Are you sure? yes | no
