This project aims to produce a fully assembled Meshtastic node based on the ESP32-S3 and RA-01SH, both of which are avaliable for assembly by JLCPCB. The only components to be bought outside are the antenna and LiPo battery. The PCB will include battery charging and SMA connector. Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source! Meshtastic utilizes LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licenses or certifications, unlike HAM radio operations. These radios are designed to rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages. Additionally, Meshtastic radios can be paired with a single phone, allowing friends

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.

This is certainly the simplest and cheapest object detection system that can serve perfectly for the presentation of the possibilities of this technology.

LaserProjector V2 is a battery-powered, ESP32-based laser XY scanner using stepper motors to deflect the beam. It has auto-homing functionality, and can be controlled wirelessly (Wi-Fi & Bluetooth).

Lightweight ESP32-based IoT module for remote data logging enabling the collection and upload of 3D printing statistic values to a cloud server, as well as displaying them locally on a dedicated display. The project also involves extending the Marlin project by adding a custom G-code command at the firmware level.

This is a visually impressive hourglass simulation project, and despite its simplicity, there are many possibilities for modifying most parameters.

Wire up your RGBW LED strip to Wi‑Fi with ESPHome! This 12 V controller drives four PWM channels—R, G, B, and W—using a simple ESP8266 board. Ideal for Home Assistant, perfect for ambient lighting, and totally local.

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.
