We’ve seen multiple DIY drone projects over the years, each bringing something unique to the table. At CircuitDigest, we even built our own version of a Wi-Fi controlled drone using the ESP32, which later evolved into LiteWing—an open-source drone development platform aimed at makers and researchers. Continuing in this spirit of accessible drone building, Vishal Sharma from the YouTube channel Pro Know has shared his own variation of the ESP32-based drone that uses popsicle sticks for its frame.
In Vishal's design, the flight controller is powered by the ESP32 and built on a custom PCB. The firmware is based on Espressif’s ESP-Drone project and flashed using the ESP Launchpad tool, making the setup process approachable for beginners. Vishal also gives credit to community efforts that helped make the firmware more accessible. The drone creates its own Wi-Fi hotspot, allowing users to connect and control it using the ESP-Drone mobile app.
The frame is made entirely from popsicle sticks, designed using Fusion 360, and weighs just 12 grams. A 3D-printed version is also available for those who prefer a sturdier build, which weighs around 18 grams. The complete assembly, including motors and a 450mAh LiPo battery, brings the total weight to around 50 grams. Basic controls like roll and pitch trim can be adjusted through the app, and LED indicators provide status updates for calibration, battery, and connectivity. Vishal reports a flight time of around 7 to 8 minutes and hints at future upgrades like barometer-based altitude hold and a live video feed.
