I am a DIY hobbyist by passion and a power Engineer by profession. Most of my works are related to Solar Energy and Arduino. My main goal is to provide basic need of electricity and improve the socio-economic positions of rural people. So I work hard to make open source product to generate, harvest and store clean energy. Apart from Electronics I love 3D printing, Woodworking and to make crafts from used household stuff.
