Electronics
Volts, signals and flying robots.
From Ohm's law to autonomous machines — the fundamentals of electronics, then deep dives into drone racing and robotics.
Fundamentals
Circuits, components and signals.
- Ohm's law Ohm's law links voltage, current and resistance with V = I x R, and underpins power P = V x I. ●○○○○ 12 min
- Series vs parallel circuits How resistance, current and voltage combine differently in series and parallel, and why homes are wired in parallel. ●●○○○ 14 min
- Capacitors & inductors The two energy-storing reactive components: capacitors store charge in an electric field, inductors store energy in a magnetic field. ●●●○○ 15 min
Drone Racing
Build, tune and fly FPV quads.
- The FPV drone system The main subsystems of an FPV racing quad and how the frame, power, control and video parts connect. ●●○○○ 13 min
- Brushless motors & ESCs Why quads use brushless motors, how an ESC commutates them, what KV rating means, and basic prop pairing. ●●●○○ 14 min
- LiPo batteries for drones Cell count, capacity, C-rating, storage voltage and the critical safety rules for handling drone LiPo packs. ●●●○○ 15 min
Robotics
Sensing, actuation and control.
- Sensors & actuators in robotics How robots sense their world (IMU, encoders, ultrasonic, IR, cameras) and act on it (motors), through the perceive-think-act loop. ●●○○○ 14 min
- Microcontrollers & GPIO What a microcontroller is, how its digital and analog I/O work, PWM, and how it reads sensors and drives outputs. ●●●○○ 15 min
