A theremin , named after its Russian inventor in the early 1900's, is an electronic musical instrument that is controlled without any contact by the musician. Volume is controlled by moving one hand near one antenna, while pitch is controlled by moving the other hand near a second antenna. The sound is generated by a pair of high-frequency oscillators.

The PocketLab HotRod is a fun and creative take on the classic “physics cart”, except it’s not boring and it doesn’t look like a brick on wheels. Check out the video and read more here to learn more.
It’s not always enough to just hear music. Many of us enjoy visualizing it while listening. 4th of July fireworks are commonly synced to Sousa’s The Stars and Stripes Forever. Concert goers see spotlights flashing to their favorite pop songs. Modern home owners play their sound systems synchronized with Phillips Hue lighting and nanoleaf® light panels with a Rhythm module. For many years, classic visualizers have di
Exploration
As a hiker changes elevation during a hike, the atmospheric pressure will change. The air pressure at sea level, is vastly different than the air pressure at the top of a mountain. In some regions, it can be even be difficult for people who are not from that region to breathe, because they are not used to the changes in altitude. Using PocketLab, determine the relationship between elevation and air pressure.
