The Spoke Calculator was the first web app I made during my work term at Grin Technologies. Given the rim and motor being used for an ebike, it calculates the spoke length for a wheel build, the angle spokes will make with the rim, and renders an approximation of what the wheel build will look like. Custom dimensions for the motor and rim can also be entered. This app is heavily used by the wheel manufacturers at Grin Technologies itself, and also around the world by DIY ebike builders.
- The motor and rim entries in the drop-downs, along with their dimensions, are retrieved from a MySQL database so that newer motors and rims can be easily added in the future.
- A live counter was implemented which counts the number of spoke calculations made.
- Worked with one other developer.
- The app has been getting about 250 new spoke calculations every day since its launch in late May, 2014.
