Learn to Build Drones from Scratch
This is the on-ramp for people who have never built a drone. No prior electronics experience assumed. By the end you will understand how a multirotor stays in the air, what parts you need, and how to configure your first flight controller.
Beginner topics covered
How drones fly and why quadcopters need four independent motors. Reading a motor KV rating and matching it to a propeller. Choosing an ESC with adequate current headroom. LiPo battery C-rating, storage voltage, and fire safety. Radio protocols: PWM, PPM, SBUS, and ExpressLRS. Flashing Betaflight or ArduPilot to a flight controller. Failsafes and pre-flight checks.
What comes next
After the beginner path you progress into VTOL fixed-wing design, autonomous mission planning, and companion computer integration for computer vision workloads.
