Around the EI offices lately, something magical has happening.  Folks are laughing more… There’s a lighter spring in their step and a happy-go-lucky chirp in their voices…  It’s as if we have all become enchanted.

Micro LEDs and Motion

The micro LED lights  known as Rave lights have become popular with students at dances and parties.   With the  lights turned down, kids have these lights on their hands or in gloves, and the results are totally awesome when they wave their hands around.  Watching this phenomenon takes me back to the era of the disco ball and laser light shows.  It became apparent to me that these little lights would be fantastic when incorporated into the study of motion. Using these lights and a digital camera, it would be fairly easy to record the motion of moving objects for closer study.  Rolling, spinning , swinging, falling, projectile motion, etc. can all be captured using a camera and these little lights.

Can you figure out how these were done?
