EM Chanrithykol is the founder of Doydoy, what he calls “a low cost STEM learning and innovation tool” for children. Doydoy was developed when Chanrithykol attended the Think Global Make Local (TGML) course run by ARC Hub PNH in 2015 and funded by USAID’s Development Innovations. The product was designed to serve kids who didn’t have a lot of money but were interested in building and design, and is made with low-cost plastic straws and 3D printed joints that can be put together to build different structures like houses or boxes. The TGML course provided free, high quality product development training with a focus on design topics ranging from 3D printing, to electronics and robotics.
