Simple Science Episode #05: Sulfur

Episode #05: Sulfur!

Sulfur is one of the most abundant elements in the universe. Few materials are so linked to life and death as the humble sulfur atom. Present in every cell of our bodies, it is impossible to escape the importance of element #16 on the periodic table. Join Ratticus as he explores the physical and chemical characteristics of this fascinating element: sulfur.

About Ratticus:

Ratticus started performing in 1999 as the lead guitarist of the “Dixieland Possum Band.”  After a break of over ten years, Ratticus has returned with a passion for science education and video.  Inspired by the words of Jules Verne, Ratticus’ vision for science education is to present complex scientific principles in a clear and simplistic format while preserving the awe and wonder inherent to scientific discovery.

Everything great in science and art is simple. What can be less complicated than the greatest discoveries of humanity – gravitation, the compass, the printing press, the steam engine, the electric telegraph?     -Jules Verne

Simple Science Returns With a Lesson on DC Motors

Simple Science Episode #04: DC Motors

DC motors are all around us. From our computers to smartphones to the clocks on the wall, few electric devices do not contain at least one DC motor. How do they work? Ratticus explores DC motors through a series of experiments and activities that show the complexity and the simplicity of their design. In the end you’ll have a greater appreciation for these often hidden wonders of modern life.

Simple Science Episode #02: Resistors

Simple Science #02: Join the Resistance!

In Episode #02 of Simple Science, Ratticus returns to explore the world of electronics by studying one of it’s simplest components: the resistor. In Activity One, Ratticus uses a digital-multimeter to measure the resistance of several different types of resistors and makes an interesting discovery about apples. In Activity Two, Ratticus uses a homemade variable resistor to modify a simple tone generator into an electronic instrument.

Luna Coon Part 01

I started to make Luna Coon after I decided my skills were at a minimal level to do so. She is constructed from wood, clay, metal, and synthetic fur. I decided to build her using my old style of construction and no electronics, which was harder to do than I expected.

Ghoulson

Ghoulson is a scarecrow built for the Huntsville Ghost Walk to compete in the Huntsville Botanical Garden’s “Scarecrow Trail.” His eyelids blink by the way of a Pololu Micro Maestro servo controller paired with a high torque servo motor.  His eyes also glow a ghastly blue when not in direct sunlight.
