Project Progress: Gyroscopic Watch Winder

My main project has honestly been progressing slower than I initially expected. My senior design project has had many deliverables, and I have had to focus most of my attention on that. Because of my senior design project, I have not been able to focus solely on the project.

Because of these time constraints, I have shifted my design to make it easier to complete. As mentioned in my original design plan, I will be CADding my geometries and design by using pre-existing ones as inspiration. After looking at the CAD, I realized it is smarter to slightly adapt pre-existing designs instead of starting from scratch. I will also use additive manufacturing (3D printing) to create all the pieces. I initially planned on using wood to make the design, but I realized I do not have time to complete the project this way. Because of the time needed to dry wood glue and go to the ITLL to do the project, I am opting for 3D printing. I can also make more iterations when 3D printing because I have a printer at home.

I have talked to ITLL people and will get an Arduino from them to do the project. I plan to buy my own eventually because I cannot keep the Arduino from the ITLL. However, I have not yet purchased my own and will probably wait until the summer to do this.

I have been compiling all the code posted online that could help with this project. I have also been setting up preliminary sketches of how the electronics will work.

My main difficulties with the project are the CAD and the code. I am not very experienced in writing code and using Arduinos, so I have been using online resources and code that is already written and trying to understand what it does. I have also been working pretty hard to try and source all of the different components. This has taken some time, planning, and discussing with ITLL staff to ensure I have everything necessary to complete the project.

The main issue with CAD is maintaining a realistic geometry while following the aesthetic. The model is becoming pretty complicated because of the mid-century modern aesthetics’ organic silhouettes. The complex geometries are the primary reason that I decided I should not be creating the model from scratch. The new model I am working on is a slight setback because it is changing my initial plans, but it will help in the long run.  Overall, I am still confident that I can finish the project on time, but my progress is much smaller than I originally planned.
