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

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

Artificial plant with environmental monitoring

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

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

My curiosity to create something new and interesting got me into this gothic style rechargeable lantern. A Gothic Lantern is a captivating piece of lighting that brings the allure of the Victorian Era into your home.

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.

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

Flea-Scope™ is a very low-cost ($18 from Elecrow) and easy-to-use 18 million sample-per-second (Msps) USB oscilloscope and mixed-signal logic analyzer with a built-in waveform generator, and so much more, based on the PIC32MK MCU!
