DIY off-grid terminal using Arduino Mega, TCM3105 modem, GPS, and error correction for resilient text communication.

Invisible indoor pollutants? This ESP32 IoT node (AP mode) reveals them—TVOC, eCO₂, temperature, humidity rate —via its own Wi-Fi dashboard.

Cutting-edge farm security system that revolutionizes protection for agricultural asset.

Introduction of the 5″ CrowPanel ESP32 Display, featuring a capacitive touchscreen and a resolution of 800×480. As its main control processor, it uses the ESP32-S3-WROOM-1-N4R8 module. This is a dual-core 32-bit LX6 microprocessor with integrated wireless capabilities, supporting both Wi-Fi and Bluetooth. It runs at a main frequency of up to 240 MHz, delivering powerful performance suitable for IoT applications.

This project features an e-paper display that shows real-time weather information, including temperature, sky conditions, humidity, and visibility. It's an energy-efficient solution with a sleek design.

This project demonstrates a long-range smart home control system built using RYLR998 LoRa modules, NodeMCU ESP8266, and Arduino Uno. Unlike traditional WiFi-based home automation systems, this project uses LoRa (Long Range communication) technology to enable wireless communication up to 5KM range under line-of-sight conditions.

I built a scalable ESP NOW hydroponic network using 3D printed components and off the shelf sensors to automatically care for plants with minimal intervention, starting small in my apartment but expandable for future vegetable gardens.

Your gateway to a simpler, smarter tomorrow!

This project is an 8-channel relay controller based on the ESP32-C3 SuperMini. It provides multi-platform IoT support out of the box for: ???? Blynk IoT Cloud ????️ Arduino IoT Cloud ????️ Home Assistant (via MQTT) ????️ Amazon Alexa voice control ???? Google Home voice control ???? Tasmota Firmware (for power users) ???? Google Firebase integration

A small project combining ESP8266 with a vintage Soviet Nixie tube from the 70s to create an artistic clock

Encrypted off-grid LoRa messaging terminal with GPS sync and dynamic key destruction. No network, no trace, full control.

“The Cyber Clock” , A rechargeable battery-powered 1.51-inch transparent OLED clock with accurate internet time and date. It can also measure your room temperature and humidity from an onboard sensor. It can show the battery percentage as well, with a fully 3D-printed Cybertruck body. It also comes with rollable wheels so you can play with it. It is also possible to lock the wheels by tightening screws so it wouldn't fall from the desk by accident !.
