Weather Crow is an ESP32-S3 based weather station featuring an E-paper display that shows current weather conditions and forecasts. This initial release provides a complete solution for monitoring local weather with minimal power consumption through efficient deep sleep cycles. the project is under the MIT license, so you can modify or chage as you want!!

A replacement PCB for Hori Pad Mini controllers supporting software calibration & Hall Effect sensors.

A Short PCB tutorial so you can make your first PCB.

The DIY Heating Booster helps you get more out of your existing radiator – without modifying your heating system. An ESP32 controls 12V fans mounted underneath the radiator, automatically turning them on when the radiator gets warm to efficiently distribute heat throughout the room. The control logic works standalone with a local temperature sensor, but can also be fully integrated into Home Assistant. Perfect for cold spots, smart upgrades, and energy-saving DIY solutions.

This project is the development of a fully integrated, standalone Voice Assistant built upon the ESP32-C6 microcontroller. It leverages two major cloud AI services—Gemini 2.0 Flash for intelligence and Murf AI for realistic speech generation—to create a seamless, conversational experience for the user.

A custom IoT controller that manages street lighting over LoRaWAN and turns each streetlight into a fixed BLE beacon for proximity-based smart city services.

Build the ESP-FLY, a tiny, phone-controlled ESP32 pocket drone powerful enough to fly indoors & outdoors!

A US-based health tech startup came to us with a working smartwatch prototype built on dev boards and jumper wires. It measured heart rate, SpO2, and skin temperature, synced over BLE, and lasted about 14 hours on a 200 mAh battery.
