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.

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

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.

In the year 2021 I created a "Internet Hardware WatchDog" using NodeMCU which reboots my home router whenever there is an issue with the Internet. This device sits next to my router and happily takes care of it whenever it has a hiccup. This year, I wanted to extend the watchdogs horizon by adding an "Internet Status Notifier" that displays the current status of the Internet using an RGB LED.

This universal power supply board is a perfect match for powering the low power devices such as MCUs, Sensors & Modules with the best load and line regulation features. The board can take an AC or DC input of as low as 8V and as high as 28V to provide a multiple DC output voltages like 3.3V, 5V, 12V, variable DC output, and the output same as the input. The maximum load regulation is measured to be 60mV and the maximum line regulation is measured to be 0.2%/V.
