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

DIY Groovebox / Synthesizer / Sequencer with 6 OP FM, VA, 2x16 MIDI Channels and 8 voice Chromatic Sample Player, based on a Teensy 4.1

The ESP32 Portable Inductance Meter is a low-cost, high-precision tool designed for students, researchers, and hobbyists, offering ESP32-powered processing, dual reference capacitors for enhanced accuracy, and a rechargeable portable design—making inductance measurement more accessible and reliable for educational and experimental use.

3D-printable watch case specifically adapted for the Elecrow ESP32S3 PCB with a round display, allowing you to turn this electronic board into a functional smartwatch. This project provides a practical and stylish solution to integrate the ESP32S3 into a wearable format while maintaining access to its advanced features. https://cults3d.com/zh/3 Features of the Case Ergonomic and modern design Easy and optimized 3D printing Access to the PCB's ports and sensors Robust and lightweight structure Compatible with standard watch straps With this case, you can wear a fully functional ESP32S3 on your wrist, add sensors, and create your own applications for home automation, health tracking, smart notifications, and much more. Elecrow is organizing an online competition, and I have submitted this project. If I win, I will release this case as Open Source and make it freely available to the entire community.
