This is certainly the cheapest and simplest Internet radio that you can make yourself if you have minimal knowledge in the field of electronics, and all thanks to this universal and practical display module.

Effortlessly monitor your home's energy consumption with the DIY Smart Powermeter, seamlessly integrated with the user-friendly Home Assistant platform. This powerful project provides real-time data on your household's energy usage and offers the added convenience of a snapshot of your grid's status whenever you open the electric closet, thanks to the 2.9' e-paper display. Featuring an integrated 230VAC to 5VDC regulator, the ESP32-S2 efficiently harnesses power from surrounding wires for optimal performance. The Smart Powermeter supports up to six different CT clamps, with or without a burden resistor, allowing for versatile monitoring options. Additionally, it can measure ambient temperature, giving you comprehensive insights into your energy consumption and surroundings.

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

Expansion board for ESP32 boards.

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.

I am going to use this screen to create a touch panel for my home automation system.
