Identify noxious air bubbles lurking in the substrate w/ ultrasonic scans and assess water pollution based on chemical tests simultaneously.

Ask anything, get answers on the go! Build a portable voice assistant with Gemini AI & ESP32 for seamless, smart voice interactions

Mentor Mitra AI is a smart educational toy with a custom ATmega328P PCB that integrates the AI Thinker VC02 chip,temperature sensing, interactive voice features, and a web dashboard for personalized learning insights.

The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts various devices using an ESP32 and nRF24 modules, causing plenty of noise and sending unnecessary packets (DoS). It interrupts: The whole 2.4GHz broadband! Everything that works on 2.4GHz is being interfered, like: audio in speakers being transmitted over bluetooth, microphones on 2.4GHz, smartphone connections, WiFi, RC Drones (etc.), IoT devices, smart gadgets, wireless keyboard & mouse, just anything on 2.4GHz! Ideal for controlled disruption and security testing. Based on 2,4GHz communication. It has a big range (over 30Meters+ - may vary on your antenna and hardware setup!) on newest Bluetooth versions with casual 2.4GHz antennas, you can easily increase this aswell by taking some simple "bigger" router antennas. An amplifier (2.4GHz) may be an good option too! Remember that jamming is illegal and should not be used with malicious intent! This is strictly for educational purposes only!

The MQ One is born as a new development platform that includes all the necessary components ready to use in order to easily learn about embedded systems programming.

An alternative clock with a unique style, easy to build, and a great piece of furniture! Introducing the new Floppy Voltmeter Clock!

In this project, we will build a tiny internet clock connected to your wifi to get time from NTP servers.

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!!

Artificial plant with environmental monitoring

Buying a ready-made power supply would be too easy, so I decided to make my own.
