A device designed to detect cosmic rays (primarily muons) using a grid of Geiger-Müller sensors. Cosmic rays are high-energy particles originating from outside the Solar System, making this project a tool for observing their interaction with Earth's atmosphere.

A home plant watering device based on a simple 6-pin PIC microcontroller and 74HC chips.

Data logger shield based on STM32+ESP32. Has: LCD, keyboard, WIFi, UART and SD card for data storage. Input is as pulse counter and UART communication.

Device for quantitative analyze energy spectra of gamma-ray sources. Allows to study what radioactive isotopes in what quantities are present in measured sample.

Nuclear radiation sensor with ionization chamber as a detector. Hard to make, IMHO inferior to semiconductor detectors.

Nuclear radiation sensor with photodiode as a detector. Photodiode doesn't require high voltages as GM tubes do. Smaller size makes better resolution. Side effect is electronic must be more sensitive.

Temperature, humidity, and air pressure monitoring with an easy-to-solder Raspberry Pi shield.
