I build hardware
from first principles.
Student engineer designing autonomous UAVs, custom PCBs, and 3D-printed systems — every project taken apart, understood, and documented from the first sketch to the final BOM.
Featured builds
Four projects that best represent how I work — from concept through fabrication.
Every build
Nine projects, from a battery-free NFC card to an 850mm mapping drone.
Who's building this
I'm Sreeni — a high school student in South Brunswick, NJ who builds hardware from first principles. Most of what I know about flight controllers, PCB layout, and NDVI imaging didn't come from a classroom. It came from taking things apart, reading datasheets late at night, and debugging DRC errors nobody warns you about.
My work spans autonomous UAVs, custom PCBs, rocketry avionics, and 3D-printed systems — each one documented start to finish in a build journal as I go, mistakes included. I'd rather design a part myself and get it wrong twice than buy a pre-made one that gets it right the first time.
