The Musical Laser Rainbow Machine makes music into colored laser patterns of light that move and respond to the music. Music is divided into 6 frequency bands. Three beams of light are projected, two of those beams are made by combining red, green and blue lasers, and the third beam is red. Seven lasers are changing in intensity with 6 frequency bands of music. It was featured with full instructions on how to build it in Nuts and Volts Magazine, May/June 2018, cover story.
Here the laser beams are made visible with smoke. Three beams exit at the left, where they would normally go through rotating pieces of lumpy clear glass. The upper and lower beams are a combination of red, green and blue lasers, which are combined by going through mirrors that pass one or two colors and reflect another color.
Castle In the Clouds
A 3D printed castle is floating in air by magnetic levitation. Electricity is wirelessly transferred to the castle from below, to light the window of the castle and the clouds.
My first Rolling Ball Sculpture. It got me started making crazy things. I thought maybe people would think I was a little crazy making such a silly thing. Then it won Best of Show at the county fair, then “Creativity Award” (the top prize) at California State Fair’s Best of Show competition, went on the front page of the local newspaper, and I decided that people like crazy machines.
