Building projects
with curiosity,
and a love for engineering.
A selection of things I’ve built across hardware, web, and experiments.
My first hardware project — a minimalist LED desk sphere that displays study modes using soft colors and animations. Built using an ESP32.
A global youth-led platform with 8,000+ users from 70+ countries, delivering unbiased innovation, space, and tech news — no ads, no politics.
An AI chatbot built as part of BitBuzz, inspired by Chanakya’s principles to provide strategic and wisdom-driven responses.
A custom macropad designed for telescope workflows and astrophotography control setups.
Prize-winning school project — a platform for nature lovers promoting sustainability and local Indian vendors.
A kid-friendly chatbot built using Code.org App Lab to make learning interactive and engaging.
A space-themed version of Flappy Bird built for fun using Code.org, focusing on simple mechanics and visual experimentation.
Elon Musk–themed app created for a design championship using Code.org.
Exploring the night sky through careful observation and long-exposure captures.
I’m Hridhaan Sahay, a high-school student interested in space, technology, and building things from scratch.
I’m the creator of BitBuzz, a youth-led platform delivering unbiased innovation, space, and technology news.
I also share what I learn through videos on YouTube (@Astro2HR).
