I was talking about my project with my dad, just brainstorming, when he gave me the suggestion to build him a heartbeat sensor that he wears on his wrist that he can use while working out. He wanted something that would indicate when his heart rate was outside of a certain range. I plan on designing a watch that would tell the user to speed up, slow down, or maintain their beats per minute using LEDs that light up depending on the situation. Now that I had an idea of what to build, I needed an aesthetic to implement into my design. I remembered that my dad has a Harley Davidson Sportster and loves the motorcycles, so I decided to that as my aesthetic.
The main inspirations for the design is based on the Harley Davidson Motorcycle Brand and Biker culture. Riders typically wear black leather jackets, sometimes with their group’s emblem, and their bikes are usually black with flames along the sides. Also, the chrome of the pipes and engines of their bikes pop out and grab your attention. I plan on using black leather for the bands on the watch and painting the case of the sensor as black or silver with flames on the sides of it. I want to use a green, yellow, and red LEDs like a stop light to represent the need to speed up, maintain, or slow down their heart beat. If I have time, I plan on painting the Harley Davidson Logo on the case as well.
A critical component for the project is the case for the arduino that will measure the user’s heat rate. It needs to be able to hold the arduino comfortable while also not affecting the person while they are working out. I also wanted the design of the case to work with the aesthetic I established. I based the design of it on the “peanut chopper” style gas tank that are very popular on motorcycles.
