A small project combining ESP8266 with a vintage Soviet Nixie tube from the 70s to create an artistic clock

The P-Bit is a compact, modular IoT platform designed for hands-on STEAM and sustainability education. Equipped with temperature, humidity, light, sound, and soil moisture sensors, it allows students to collect real-time environmental data, analyze trends, and connect to the cloud for deeper insights. It features an ESP32-WROOM-32E processor with Wi-Fi and Bluetooth connectivity, a 1.8” TFT display, a rotary encoder, and GPIO/I²C expansion for additional sensors. Students can monitor microclimates, optimize irrigation, and study noise pollution through an intuitive interface. By integrating IoT and data science into the classroom, P-Bit helps address the urgent need for climate literacy, empowering the next generation with the tools to understand and protect the environment. More than just a sensor, it is a gateway to smarter, more sustainable learning.

This is an interesting and simple to make two player Arduino game that can be made in less than a day.

Project #15: Environment – DHT11 – Mk24

Simple and inexpensive way to make such a device, if you have basic knowledge of electronics and microcontrollers.

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.

In this tutorial, I am going to show you guys how to design this "Transformers PCB Badge" and how to solder the components to it.
