+At one point, I remember being shown a picture of a gear themed clock, and being rather annoyed that despite clocks running on gears, and this clock being gear themed, it's "pretty" gears didn't _do_ anything for the mechanism. Ever since, I've had the idea in the back of my head to design a clock where all the functional gears are clearly visible.
+
+It was during my final project for a CAD course that I decided to actually have a go at it, and came up with a design based on [cycloidal drives](https://en.wikipedia.org/wiki/Cycloidal_drive). Specifically, I was inspired by [Levi Janssen's](https://www.youtube.com/watch?v=6xoCeliJ11Q) video showing a design for a single-plane, multistage cycloidal gearbox, and based my design for a clock of this style of gearbox.

-The [Technology Student Association](tsaweb.org) is a national organization that hosts STEM competitions at the national, state, and regional levels. School chapters of middle and high school students compete in a wide range of individual and team events, ranging from programming to model bridge construction to fashion design. In the 2021-22 school year, I was the president of the York Suburban High School chapter of the TSA.
 
-I also competed in the Flight Endurance competition, where participants build lightweight rubber band powered airplanes designed to stay airborne as long as possible while adhering to the weight and size constraints. The plane I built weighted 9 grams, and could fly for roughly 90 seconds before running out of power.
+I was able to come to a design I was happy with by the project deadline, but the clock was rather large, had power or drive system, and was not particularly manufactuable. However the mechanism itself was functional, and it served the purposes of the class project, which did not require me to actually build my design.
+Since that class focused on comparing 2 CAD softwares - CREO Parametric and Solidworks, I modeled my design and produced drawings in both, which are shown below. I find it interesting to compare the differences in visual style between the two softwares - CREO's drawings(left) are much more striking.

+More recently, I decided to go back and work to redesign the clock into something both manufactuable  and beautiful. The design I came up with uses stainless steel sheet for the gears, held onto the back plane with magnets and driven by a small stepper motor. I managed to shrink the design somewhat, which was aided by designing the gears to be more parametric, making iteration on gear profiles and sizes much quicker.
+This design is meant to be constructed out of steel plate, with the gears held onto the back plane by magnets to make for an extremely minimal design. The cad for this version was done using onshape, [and is available online](https://cad.onshape.com/documents/6c451e4294f56b11346f6eca/w/8283c5e1aac9d7144dc17c54/e/ba40aee599be0f51e1387e2e?renderMode=0&uiState=658b97496f79aa00b39778c0) I hope to begin prototyping this design shortly.

+It's difficult to convey just how light these aircraft look and feel, and they are quite difficult to build well. Because there is no control input to the planes, they must be tuned to climb gradually at the beginning - when the rubber band provides the most power - but not so much that they strike the roof. The plane must also be tuned to circle slowely to avoid hitting the walls of the room, which is challenging as the turn radius will vary depending not just on the tuning of the plane, but also the amount of power it's producing and any air currents it runs through.
