Here is my poster, where I go more in depth on the inspiration, code, mounting, hall effect sensor, and electronics.
This is a quick description of my project and why I wanted to do it.
This is a demonstration of my project.
I mounted the magnet and sensor to an RC car to see if the speed being displayed was accurate and to get a general sense as to how I would mount it to the go-kart.
I laser cut a cardboard version of the box to hold all of the elctronics to make sure that when I printed everything in wood, it would be prefect.
This is the final product on the go-kart with the mounted wood box and the working speedometer/timer.
