I have a bunch of my creations to display. Par One is a rolling ball sculpture with miniature golfers hitting balls on a wacky little golf course, using microcontrollers, motors, linear actuators and servos. My Musical Laser Rainbow Machine has seven colored lasers controlled by music to create colorful patterns that move to the music. It involves the use of mcrocontrollers and many 3d printed parts. The Floating Castle is a 3d printed castle that floats on a magnetic field, with lights inside that are powered from below and through the magnetic field. A Weather Machine displays graphs of temperature, humidity, wind speed, air quality and rainfall. Also are a backpacking banjo, music kaleidoscope, and LED creations. My display won an Editor's Choice award at the Bay Area Maker Faire in 2019.
Fun with Oobleck
Oobleck is a non-newtonian fluid. That is, it acts like a liquid when sitting still, but acts like a solid when a force is acting on it (strained). Oobleck gets its name from the Dr. Seuss book Bartholomew and the Oobleck where a gooey green substance, Oobleck, fell from the sky and wreaked havoc in the kingdom. Here the Oobleck will be made from corn starch and water on top of a speaker. You get to control the excitation using Frequency and Amplitude knobs to watch the Oobleck dance! If you touch the dancing peaks the liquid will feel like rubber.
