The M&L hourglass
In my Light, Sound, and Time this unit we have been learning about time. We looked at different time telling devices, longitude and latitude, pendulums, sundials, and more. We learned about the cosmic calendar and what it meant along with the Big Bang! We learned how to use the Pythagorean theorem, how to find the period, arc length, and arc angle. We also learned about tools like an escapement, gnomon, sextant. Taking all of this information we were given the task of creating or adding to a time telling device. Below you can see a video of me explaining my device, how it works and why it is important. Hope you enjoy!
History
I got my inspiration from the original hourglass that first appeared in Europe in the eighth century. It may have been made by Luitprand, a monk at the cathedral in Chartres, France. It was widely used throughout western europe, an hourglass is a device used to measure the passage of time. There are two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance (historically sand) from the upper bulb to the lower one. I liked the idea of the hourglass but I wanted to make it for a bigger audience.

Overall, I enjoyed making this device. I don't think many products are made to be used by everyone, they are usually targeted at a specific audience and people that may need a special or specific type of design are not thought of. I think my device can be used for everyone even if you aren't hard of hearing or blind.
