This project was part of a first year engineering projects class where I was put into a team and given a client for whom which we created a product. Our client has a child with autism and wanted us to create a device that could help improve his cross body coordination. To do this we decided on creating a device that uses a balance board and hand panel combination that uses the core muscles on the balance board and your hands to press the buttons on the hand panel as they light up.

For eight months, I’ve been designing a small-scale hydroelectric turbine to help reduce Bali’s dependence on fossil fuels, which currently power 98% of the island. Inspired by the local subak water system, I developed a turbine based on the Archimedean screw for its resilience, low environmental impact, and simplicity. After several failed prototypes and much experimentation, including 3D printing and custom gear systems, I finally produced enough electricity (10 watts) to charge a phone. I’ve learned to love the engineering process itself. All files and instructions will be shared freely so others can build their own turbine too.
